| Overview |
| |
| This extension implements a subset of ARB_color_buffer_float on top of |
| OpenGL ES 2.0. |
| |
| This extension enables rendering to floating point RGB textures. When |
| this extension is enabled: |
| |
| * The 32-bit floating point type GL_RGB32F becomes available as a |
| color-renderable internal format. Textures created with type = FLOAT, |
| and internal format GL_RGB32F, can be attached to framebuffer object |
| color attachments for rendering. |
| |
| * GL_RGB / GL_RGB32F 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 RGB textures may still be created also with the unsized |
| GL_RGB internal format, but whether such textures are renderable is not |
| guaranteed. |
| |
| New Tokens |
| |
| Accepted by the <internalformat> parameter of TexImage2D: |
| |
| GL_RGB32F 0x8815 |
