| OpenGL ES Extension #?? |
| |
| Dependencies |
| |
| Requires OpenGL ES 3.0 |
| |
| Written against the OpenGL ES 3.2 specification. |
| |
| Overview |
| |
| This extension allows the OpenGL context to indicate if it supports rendering |
| defined pixel values when there's an interface mismatch between the fragment |
| shader and the draw framebuffer. |
| |
| New Procedures and Functions |
| |
| None |
| |
| New Tokens |
| |
| Accepted by the <cap> parameter to IsEnabled and the <pname> parameter to |
| GetBooleanv, GetIntegerv, GetFloatv, and GetInteger64v: |
| |
| ROBUST_FRAGMENT_SHADER_OUTPUT_ANGLE 0x96B9 |
| |
| Additions to the OpenGL ES Specification |
| |
| Add to the end of section 15.2.1 "Selecting Buffers for Writing" |
| |
| If the fragment shader does not declare output variables that would be |
| written to a bound draw buffer, the contents of the bound draw buffer |
| remain unchanged. |
