Name Strings
GL_CHROMIUM_color_buffer_float_rgba
Version
Last Modifed Date: February 7, 2014
Dependencies
This extension is written against the OpenGL ES 2.0 specification.
OpenGL ES 2.0 is required.
OES_texture_float is required.
Overview
This extension implements a subset of EXT_color_buffer_float on top of
OpenGL ES 2.0.
This extension enables rendering to floating point RGBA textures. When
this extension is enabled:
* The 32-bit floating point type GL_RGBA32F becomes available as a
color-renderable internal format. Textures created with type = FLOAT,
and internal format GL_RGBA32F, can be attached to framebuffer object
color attachments for rendering.
* GL_RGBA / GL_RGBA32F becomes an allowable format / internalformat
parameter pair for TexImage2D. The restriction in section 3.7.1 of the
OpenGL ES 2.0 spec that the internalformat parameter and format parameter
of TexImage2D must match is lifted for this case.
Floating point RGBA textures may still be created also with the unsized
GL_RGBA internal format, but whether such textures are renderable is not
guaranteed.
New Tokens
Accepted by the <internalformat> parameter of TexImage2D:
GL_RGBA32F 0x8814
New Procedures and Functions
None.
Errors
None.
New State
None.
