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.
