GL11ExtensionPackpublic interface GL11ExtensionPack implements GLThe GL11ExtensionPack interface contains the Java(TM)
programming language bindings for the OpenGL ES 1.1 Extension Pack.
The runtime OpenGL ES engine may or may not implement any
particular extensions defined in the extension pack. Functions
that require a particular extension will throw an
UnsupportedOperationException if the extension is not
available at runtime.
The OpenGL ES 1.1 Extension Pack consists of the following extensions:
- OES_texture_env_crossbar
- OES_texture_mirrored_repeat
- OES_texture_cube_map
- OES_blend_subtract
- OES_blend_func_separate
- OES_blend_equation_separate
- OES_stencil_wrap
- OES_extended_matrix_palette
- OES_framebuffer_object
The specification for the OpenGL ES 1.1 Extension Pack may be
found at http://www.khronos.org/cgi-bin/fetch/fetch.cgi?opengles_spec_1_1_extension_pack.
The documentation in this class is normative with respect to
instance variable names and values, method names and signatures,
and exception behavior. The remaining documentation is placed here
for convenience and does not replace the normative documentation
found in the OpenGL ES 1.1 Extension Pack specification, OpenGL ES
specification, relevant extension specifications, and the OpenGL
specification versions referenced by any of the preceding
specifications. |

| Methods Summary |
|---|
| public void | glBindFramebufferOES(int target, int framebuffer)(OES_framebuffer_object extension)
Bind a framebuffer.
The operations described in chapter 4 of the OpenGL 1.5
specification affect the images attached to the framebuffer
object bound to the target GL_FRAMEBUFFER_OES. By default,
framebuffer bound to the target GL_FRAMEBUFFER_OES is zero,
specifying the default implementation dependent framebuffer
provided by the windowing system. When the framebuffer bound to
target GL_FRAMEBUFFER_OES is not zero, but instead names a
application-created framebuffer object, then operations
affect the application-created framebuffer object
rather than the default framebuffer.
The namespace for framebuffer objects is the unsigned
integers, with zero reserved by the GL to refer to the default
framebuffer. A framebuffer object is created by binding an
unused name to the target GL_FRAMEBUFFER_OES. The
binding is effected by calling glBindFramebufferOES
with target set to GL_FRAMEBUFFER_OES
and framebuffer set to the unused name. The
resulting framebuffer object is a new state vector, comprising
all the state values listed in the table below. There are
GL_MAX_COLOR_ATTACHMENTS_OES color attachment
points, plus one each for the depth and stencil attachment
points.
glBindFramebufferOES may also be used to bind an
existing framebuffer object to target. If the bind
is successful no change is made to the state of the bound
framebuffer object and any previous binding to
target is broken. The current
GL_FRAMEBUFFER_OES binding can be queried using
glGetIntegerv(GL_FRAMEBUFFER_BINDING_OES).
While a framebuffer object is bound to the target
GL_FRAMEBUFFER_OES, GL operations on the target to
which it is bound affect the images attached to the bound
framebuffer object, and queries of the target to which it is
bound return state from the bound object. The framebuffer object
bound to the target GL_FRAMEBUFFER_OES is used as
the destination of fragment operations and as the source of pixel
reads such as glReadPixels.
In the initial state, the reserved name zero is bound to the
target GL_FRAMEBUFFER_OES. There is no
application-created framebuffer object corresponding to the name
zero. Instead, the name zero refers to the
window-system-provided framebuffer. All queries and operations
on the framebuffer while the name zero is bound to the target
GL_FRAMEBUFFER_OES operate on this default
framebuffer. On some implementations, the properties of the
default window-system-provided framebuffer can change over time
(e.g., in response to window-system events such as attaching the
context to a new window-system drawable.)
Application-created framebuffer objects (i.e., those with a
non-zero name) differ from the default window-system-provided
framebuffer in a few important ways. First and foremost, unlike
the window-system-provided framebuffer,
application-created-framebuffers have modifiable attachment
points for each logical buffer in the framebuffer.
Framebuffer-attachable images can be attached to and detached
from these attachment points. Also, the size and format of the
images attached to application-created framebuffers are
controlled entirely within the GL interface, and are not affected
by window-system events, such as pixel format selection, window
resizes, and display mode changes.
Additionally, when rendering to or reading from an
application created-framebuffer object:
- The pixel ownership test always succeeds. In other words,
application-created framebuffer objects own all of their
pixels.
- There are no visible color buffer bitplanes. This means
there is no color buffer corresponding to the back, front, left,
or right color bitplanes.
- The only color buffer bitplanes are the ones defined by the
framebuffer attachment points named
COLOR_ATTACHMENT0_OES through
COLOR_ATTACHMENTn_OES.
- The only depth buffer bitplanes are the ones defined by the
framebuffer attachment point
DEPTH_ATTACHMENT_OES.
- The only stencil buffer bitplanes are the ones defined by the
framebuffer attachment point
STENCIL_ATTACHMENT_OES.
| | public void | glBindRenderbufferOES(int target, int renderbuffer)(OES_framebuffer_object extension)
Bind a renderbuffer.
A renderbuffer is a data storage object containing a single
image of a renderable internal format. GL provides the methods
described below to allocate and delete a renderbuffer's image,
and to attach a renderbuffer's image to a framebuffer object.
The name space for renderbuffer objects is the unsigned
integers, with zero reserved for the GL. A renderbuffer object
is created by binding an unused name to
GL_RENDERBUFFER_OES. The binding is effected by
setting target to GL_RENDERBUFFER_OES
and renderbuffer set to the unused name. If
renderbuffer is not zero, then the resulting
renderbuffer object is a new state vector, initialized with a
zero-sized memory buffer, and comprising the state values listed
in Table 8.nnn of the EXT_framebuffer_object
specification. Any previous binding to target is
broken.
glBindRenderbufferOES may also be used to bind an
existing renderbuffer object. If the bind is successful, no
change is made to the state of the newly bound renderbuffer
object, and any previous binding to target is
broken.
While a renderbuffer object is bound, GL operations on the target
to which it is bound affect the bound renderbuffer object, and
queries of the target to which a renderbuffer object is bound
return state from the bound object.
The name zero is reserved. A renderbuffer object cannot be
created with the name zero. If renderbuffer is
zero, then any previous binding to target is broken
and the target binding is restored to the initial
state.
In the initial state, the reserved name zero is bound to
GL_RENDERBUFFER_OES. There is no renderbuffer
object corresponding to the name zero, so client attempts to
modify or query renderbuffer state for the target
GL_RENDERBUFFER_OES while zero is bound will
generate GL errors.
Using glGetIntegerv, the current
GL_RENDERBUFFER_OES binding can be queried as
GL_RENDERBUFFER_BINDING_OES.
| | public void | glBindTexture(int target, int texture)(1.1 + OES_texture_cube_map extension)
Bind a named texture to a texturing target.
The OES_texture_cube_map extension allows the
value GL_TEXTURE_CUBE_MAP to be passed to the
target parameter.
| | public void | glBlendEquation(int mode)(1.1 + OES_blend_subtract extension) Specify the
blending equation.
Blending is controlled by glBlendEquation.
glBlendEquation mode
GL_FUNC_ADD defines the blend equation as
C = Cs * S + Cd * D,
where Cs and Cd are the source and
destination colors, S and D are the
quadruplets of weighting factors determined by the blend
functions glBlendFunc and
glBlendFuncSeparate, and C is the new color
resulting from blending.
If mode is GL_FUNC_SUBTRACT, the
blending equation is defined as
C = Cs * S - Cd * D.
If mode is GL_FUNC_REVERSE_SUBTRACT,
the blend equation is defined as
C = Cd * D - Cs * S.
Errors
GL_INVALID_ENUM is generated if mode
is not an accepted value.
Associated Gets
glGetIntegerv with argument
GL_BLEND_EQUATION returns the blend equation.
| | public void | glBlendEquationSeparate(int modeRGB, int modeAlpha)(1.1 + OES_blend_equation_separate extension)

glBlendEquationSeparate allows different blend
equations to be provideded for RGB and alpha. The blend equations
are those defined for glBlendEquation.
Errors

glBlendFuncSeparate allows different blend factors to be
applied to RGB and alpha. The blend factors are those defined for
glBlendFunc.

| | public int | glCheckFramebufferStatusOES(int target)(OES_framebuffer_object extension)
Check the status of a framebuffer.
Returns one of GL_FRAMEBUFFER_COMPLETE_OES,
GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT_OES,
GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT_OES,
GL_FRAMEBUFFER_INCOMPLETE_DIMENSIONS_OES,
GL_FRAMEBUFFER_INCOMPLETE_DRAW_BUFFER_OES,
GL_FRAMEBUFFER_INCOMPLETE_READ_BUFFER_OES, or

| | public void | glCompressedTexImage2D(int target, int level, int internalformat, int width, int height, int border, int imageSize, java.nio.Buffer data)(1.1 + OES_texture_cube_map extension)
Specify a two-dimensional compressed texture image.
The OES_texture_cube_map extension allows the
values
GL_TEXTURE_CUBE_MAP_{POSITIVE,NEGATIVE}_{X,Y,Z} to
be passed to the target parameter.
| | public void | glCopyTexImage2D(int target, int level, int internalformat, int x, int y, int width, int height, int border)(1.1 + OES_texture_cube_map extension)
Specify a two-dimensional texture image with pixels from the
color buffer.
The OES_texture_cube_map extension allows the
values
GL_TEXTURE_CUBE_MAP_{POSITIVE,NEGATIVE}_{X,Y,Z} to
be passed to the target parameter.
| | public void | glDeleteFramebuffersOES(int n, int[] framebuffers, int offset)(OES_framebuffer_object extension)
Delete framebuffer objects.
Framebuffer objects are deleted by calling
glDeleteFramebuffersOES. framebuffers
contains n names of framebuffer objects to be
deleted. After a framebuffer object is deleted, it has no
attachments, and its name is again unused. If a framebuffer that
is currently bound to the target GL_FRAMEBUFFER_OES
is deleted, it is as though glBindFramebufferOES had
been executed with the target of
GL_FRAMEBUFFER_OES and framebuffer of
zero. Unused names in framebuffers are silently
ignored, as is the value zero.
| | public void | glDeleteFramebuffersOES(int n, java.nio.IntBuffer framebuffers)(OES_framebuffer_object extension)
Integer Buffer version of
glDeleteFramebuffersOES.
| | public void | glDeleteRenderbuffersOES(int n, int[] renderbuffers, int offset)(OES_framebuffer_object extension)
Delete a renderbuffer.
Renderbuffer objects are deleted by calling
glDeleteRenderbuffersOES where renderbuffers
contains n names of renderbuffer objects to be
deleted. After a renderbuffer object is deleted, it has no
contents, and its name is again unused. If a renderbuffer that
is currently bound to GL_RENDERBUFFER_OES is
deleted, it is as though glBindRenderbufferOES had
been executed with the target
GL_RENDERBUFFER_OES and name of zero.
Additionally, special care must be taken when deleting a
renderbuffer if the image of the renderbuffer is attached to a
framebuffer object. Unused names in
renderbuffers are silently ignored, as is the value
zero.
| | public void | glDeleteRenderbuffersOES(int n, java.nio.IntBuffer renderbuffers)(OES_framebuffer_object extension)
Integer Buffer version of
glDeleteRenderbuffersOES.
| | public void | glEnable(int cap)(1.1 + OES_texture_cube_map extension)
Enable server-side GL capabilities.
Cube-map texturing is enabled if cap assumes the
value GL_TEXTURE_CUBE_MAP.
If enabled, cube-map texturing is performed for the active
texture unit. See GL.glActiveTexture,
GL.glTexImage2D, glCompressedTexImage2D,
and glCopyTexImage2D.
Texture coordinates with be generated if cap is
equal to GL_TEXTURE_GEN_STR.
| | public void | glFramebufferRenderbufferOES(int target, int attachment, int renderbuffertarget, int renderbuffer)(OES_framebuffer_object extension)
Attach a renderbuffer to a framebuffer.
A renderbuffer can be attached as one of the logical buffers
of the currently bound framebuffer object by calling
glFramebufferRenderbufferOES. target
must be GL_FRAMEBUFFER_OES.
GL_INVALID_OPERATION is generated if the current
value of GL_FRAMEBUFFER_BINDING_OES is zero when
glFramebufferRenderbufferOES is called.
attachment should be set to one of the attachment
points of the framebuffer, one of
GL_COLOR_ATTACHMENTn_OES (where
n is from 0 to GL_MAX_COLOR_ATTACHMENTS_OES -
1), GL_DEPTH_ATTACHMENT_OES, or
GL_STENCIL_ATTACHMENT_OES.
renderbuffertarget must be
GL_RENDERBUFFER_OES and renderbuffer
should be set to the name of the renderbuffer object to be
attached to the framebuffer. renderbuffer must be
either zero or the name of an existing renderbuffer object of
type renderbuffertarget, otherwise
GL_INVALID_OPERATION is generated. If
renderbuffer is zero, then the value of
renderbuffertarget is ignored.
If renderbuffer is not zero and if
glFramebufferRenderbufferOES is successful, then the
renderbuffer named renderbuffer will be used as the
logical buffer identified by attachment of the
framebuffer currently bound to target. The value of
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE_OES for the
specified attachment point is set to
GL_RENDERBUFFER_OES and the value of
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME_OES is set to
renderbuffer. All other state values of the
attachment point specified by attachment are set to
their default values listed in the table below. No change is made
to the state of the renderbuffer object and any previous
attachment to the attachment logical buffer of the
framebuffer object bound to framebuffer target is
broken. If, on the other hand, the attachment is not successful,
then no change is made to the state of either the renderbuffer
object or the framebuffer object.
Calling glFramebufferRenderbufferOES with the
renderbuffer name zero will detach the image, if
any, identified by attachment, in the framebuffer
currently bound to target. All state values of the
attachment point specified by attachment in the
object bound to target are set to their default
values listed in the table below.
If a renderbuffer object is deleted while its image is
attached to one or more attachment points in the currently bound
framebuffer, then it is as if
glFramebufferRenderbufferOES had been called, with a
renderbuffer of 0, for each attachment point to
which this image was attached in the currently bound framebuffer.
In other words, this renderbuffer image is first detached from
all attachment points in the currently bound framebuffer. Note
that the renderbuffer image is specifically *not* detached from
any non-bound framebuffers. Detaching the image from any
non-bound framebuffers is the responsibility of the application.
The values in the first column of the table below should be
prefixed with GL_RENDERBUFFER_ and suffixed with
OES. The get command for all values is
glGetRenderbufferParameterivOES. All take on
positive integral values.

To render directly into a texture image, a specified image from a
texture object can be attached as one of the logical buffers of the
currently bound framebuffer object by calling this method.
GL_INVALID_OPERATION is generated if the current value of
GL_FRAMEBUFFER_BINDING_OES is zero when
glFramebufferTexture2DOES is called.
attachment must be one of the attachment points of
the framebuffer, either
GL_COLOR_ATTACHMENTn_OES (where
n is from 0 to GL_MAX_COLOR_ATTACHMENTS_OES -
1), GL_DEPTH_ATTACHMENT_OES, or
GL_STENCIL_ATTACHMENT_OES.
If texture is zero, then textarget
and level are ignored. If texture is
not zero, then texture must either name an existing
texture object with an target of textarget, or
texture must name an existing cube map texture and
textarget must be one of:
GL_TEXTURE_CUBE_MAP_POSITIVE_X,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, or
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z. Otherwise,
GL_INVALID_OPERATION is generated.
level specifies the mipmap level of the texture
image to be attached to the framebuffer and must be 0 (indicating
the base MIPmap level).
If textarget is one of
GL_TEXTURE_CUBE_MAP_POSITIVE_X,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, or
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z, then
level must be greater than or equal to zero and less
than or equal to log base 2 of
GL_MAX_CUBE_MAP_TEXTURE_SIZE. For all other values of
textarget, level must be greater than or
equal to zero and no larger than log base 2 of
GL_MAX_TEXTURE_SIZE. Otherwise,
GL_INVALID_VALUE is generated.
If texture is not zero, then
textarget must be one of:
GL_TEXTURE_2D,
GL_TEXTURE_CUBE_MAP_POSITIVE_X,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, or
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z.
If texture is not zero, and if
glFramebufferTexture2DOES is successful, then the
specified texture image will be used as the logical buffer
identified by attachment of the framebuffer currently
bound to target. The value of
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE_OES for the
specified attachment point is set to GL_TEXTURE and
the value of
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME_OES is set to
. Additionally, the value of
GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_LEVEL_OES for the
named attachment point is set to level. If
texture is a cubemap texture then, the value of
GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_CUBE_MAP_FACE_OES
the named attachment point is set to textarget. All
other state values of the attachment point specified by
attachment are set to their default values listed in
the table below. No change is made to the state of the texture
object, and any previous attachment to the attachment
logical buffer of the framebuffer object bound to framebuffer
target is broken. If, on the other hand, the
attachment is not successful, then no change is made to the state
of either the texture object or the framebuffer object.
Calling glFramebufferTexture2DOES with
texture name zero will detach the image identified by
attachment, if any, in the framebuffer currently
bound to target. All state values of the attachment
point specified by attachment are set to their
default values listed in the table below.
If a texture object is deleted while its image is attached to
one or more attachment points in the currently bound framebuffer,
then it is as if glFramebufferTexture2DOES had been
called, with a texture of 0, for each attachment
point to which this image was attached in the currently bound
framebuffer. In other words, this texture image is first detached
from all attachment points in the currently bound framebuffer.
Note that the texture image is specifically not detached from
any other framebuffer objects. Detaching the texture image from
any other framebuffer objects is the responsibility of the
application.
The entire texture image, including border texels, if any, can be
addressed with window-coordinates in the following range:
0 <= window_x < (texture_width + (2 * border)),
and
0 <= window_y < (texture_height + (2 * border))
The values in the first column of the table below should be
prefixed with GL_RENDERBUFFER_ and suffixed with
OES. The get command for all values is
glGetRenderbufferParameterivOES. All take on
positive integral values.

The OES_texture_cube_map extension provides a new
texture generation scheme for cube map textures. Instead of the
current texture providing a 2D lookup into a 2D texture image,
the texture is a set of six 2D images representing the faces of a
cube. The (s,t,r) texture coordinates are treated as
a direction vector emanating from the center of a cube. At
texture generation time, the interpolated per-fragment
(s,t,r) selects one cube face 2D image based on the
largest magnitude coordinate (the major axis). A new 2D
(s,t) is calculated by dividing the two other
coordinates (the minor axes values) by the major axis value. Then
the new (s,t) is used to lookup into the selected 2D
texture image face of the cube map.
Unlike a standard 2D texture that have just one target, a cube
map texture has six targets, one for each of its six 2D texture
image cube faces. All these targets must be consistent, complete,
and have equal width and height.
This extension also provides two new texture coordinate
generation modes for use in conjunction with cube map
texturing. The reflection map mode generates texture coordinates
(s,t,r) matching the vertex?s eyespace reflection
vector. The reflection map mode is useful for environment mapping
without the singularity inherent in sphere mapping. The normal
map mode generates texture coordinates (s,t,r)
matching the vertex?s transformed eyespace normal. The normal map
mode is useful for sophisticated cube map texturing-based diffuse
lighting models.
The intent of the new texgen functionality is that an
application using cube map texturing can use the new texgen modes
to automatically generate the reflection or normal vectors used
to look up into the cube map texture.
The following texgen modes are supported: GL_REFLECTION
MAP and GL_NORMAL MAP. The
GL_SPHERE_MAP, GL_OBJECT LINEAR, and
GL_EYE LINEAR texgen modes are not supported. Texgen
supports a new coord value GL_STR. This allows the
application to specify the texgen mode for the appropriate
coordinates in a single call. Texgen with coord values of
GL_S, GL_T, GL_R and
GL_Q are not supported.
Errors
GL_INVALID_ENUM is generated if
param or pname is not an accepted
value, or if pname is
GL_TEXTURE_GEN_MODE and params is not
GL_REFLECTION_MAP or GL_NORMAL_MAP.
