Status
|
|
|
|
Implemented.
|
|
|
|
Version
|
|
|
|
Version 1, 2018-8-8
|
|
|
|
Dependencies
|
|
|
|
OpenGL ES 3.0 required.
|
|
|
|
Overview
|
|
|
|
This extension adds 3D texture support to the functionality
|
|
provided by the CHROMIUM_copy_texture extension. Two new
|
|
functions are exported, glCopyTexture3DANGLE and
|
|
glCopySubTexture3DANGLE that perform the same copy operations as
|
|
glCopyTextureCHROMIUM and glCopySubTextureCHROMIUM, respectively,
|
|
on GL_TEXTURE_3D and GL_TEXTURE_2D_ARRAY bound textures.
|
|
|
|
New Procedures and Functions
|
|
|
|
void CopyTexture3DANGLE(uint sourceId,
|
|
int sourceLevel,
|
|
enum destTarget,
|
|
uint destId,
|
|
int destLevel,
|
|
int internalFormat,
|
|
enum destType,
|
|
boolean unpackFlipY,
|
|
boolean unpackPremultiplyAlpha,
|
|
boolean unpackUnmultiplyAlpha)
|
|
|
|
void CopySubTexture3DANGLE(uint sourceId,

|

|
Additions to the OpenGL ES 3.0 Specification
|
|
|
|
The command
|
|
|
|
CopyTexture3DANGLE
|
|
|
|
All CopyTexture3DANGLE behavior is the same as
|
|
CopyTextureCHROMIUM unless otherwise defined below.
|
|
|
|
When source texture doesn't contain a superset of the component
|
|
required by <internalFormat>, fill the components by the
|
|
following rules.
|
|
|
|
source format color components
|

|
INVALID_OPERATION is generated if the format of <sourceId> is not
|
|
one of formats in Table 1.1.
|
|
|
|
INVALID_ENUM is generated if <destTarget> is not TEXTURE_3D or
|
|
TEXTURE_2D_ARRAY.
|
|
|
|
INVALID_VALUE is generated if the texture corresponding to
|
|
<sourceId> has not been bound as <destTarget>.
|
|
|
|
INVALID_OPERATION is generated if <internalFormat> is not one of
|
|
the sized internal formats in Table 1.0.
|
|
|
|
The command
|
|
|
|
CopySubTexture3DANGLE
|
|
|
|
All CopySubTexture3DANGLE behavior is the same as
|
|
CopySubTextureCHROMIUM unless otherwise defined below.
|
|
|
|
<zoffset> specifies a texel offset in the z direction
|
|
respectively within the destination texture.
|
|
|
|
<z> specifies a texel offset in the z direction respectively
|
|
within the source texture.
|
|
|
|
<depth> specifies the depth of the texture subimage.
|
|
|
|
INVALID_ENUM is generated if <destTarget> is not TEXTURE_3D or
|
|
TEXTURE_2D_ARRAY.
|
|
|
|
INVALID_VALUE is generated if the texture corresponding to
|
|
<sourceId> and <destId> have not been bound as <destTarget>.
|
|
|
|
INVALID_VALUE is generated if either <sourceId> texture or
|
|
<destId> texture is not defined.
|
|
|
|
INVALID_OPERATION is generated if the format of <sourceId> or
|
|
<destId> is not one of formats in Table 1.1.
|
|
|
|
INVALID_VALUE is generated if zoffset is less than 0.
|
|
|
|
INVALID_VALUE is generated if z is less than 0.
|
|
|
|
INVALID_VALUE is generated if depth is less than 0.
|
|
|
|
INVALID_VALUE is generated if (<z> + <depth>) > srcDepth.
|
|
|
|
INVALID_VALUE is generated if (<zoffset> + <depth>) > destDepth.
