-
-Name Strings
-
- GL_CHROMIUM_consistent_uniform_locations
-
-Version
-
- Last Modifed Date: June 17, 2012
-
-Dependencies
-
- OpenGL ES 2.0 is required.
-
-Overview
-
- This extension guarantees uniforms always have the same locations.
-
- This allows the client program to know the locations of uniforms
- without having to wait for shaders to compile or GLSL programs to
- link to query the locations and therefore have no blocking calls
- when initializing programs.
-
- To be forward compatible the locations are provided through the
- function GetUniformLocationsCHROMIUM. LinkProgram must be called
- before calling GetUniformLocationsCHROMIUM.
-
-Issues
-
- If a uniform is unused in the actual program it may be optimized out
- by the GL driver. In this case the locations will be wrong. You
- must provide a list of only the used uniforms.
-
-New Tokens
-
- None
-
-New Procedures and Functions
-
- void GetUniformLocationsCHROMIUM (GLuint program,
- const GLUniformDefinitionCHROMIUM* uniforms,
- GLsizei count, GLsizei max_locations,
- GLint* locations);
-
- Provides the locations of uniforms assuming the list of uniforms provided
- matches the uniforms actually used in the corresponding program.
-
- <uniforms> is an array of uniforms. <count> is the number of uniforms in the
- array. <max_locations> is the maximum number of locations to write to
- <locations>. <locations> is an array to receive the uniform locations.
-
- INVALID_VALUE is generated if <count> is less then or equal to 0.
-
- INVALID_VALUE is generated if any GLUniformDefinitionHCHROMIUM's size
- field is <= 0.
-
- For each uniform <size> locations are provided. For example:
-
- static const GLUniformDefinitionCHROMIUM defs[] = {
- { GL_FLOAT_VEC2, 3, "someUniform", }, // An array of 3 vec2s
- { GL_FLOAT_VEC4, 1, "someOtherUniform", }, // A single vec4
- { GL_SAMPLER_2D, 2, "yetAnotherUniform", }, // An array of 2 sampler2Ds
- };
-
- Would return an array of locations as follows
-
- location[0] = location for "someUniform[0]"
- location[1] = location for "someUniform[1]"
- location[2] = location for "someUniform[2]"
- location[3] = location for "someOtherUniform"
- location[4] = location for "yetAnotherUniform[0]"
- location[5] = location for "yetAnotherUniform[1]"
-
-Errors
-
- None.
-
-New State
-
- None.
-
-Revision History
-
- 7/17/2012 Documented the extension
- 7/19/2012 Added <program> argument.
