Number
OpenGL ES Extension XX
Dependencies
None
Overview
This extension allows skipping texture format renderability validation if
the implementation is capable of rendering to the underlying texture
format. This can be useful in situations where textures are created
externally and the current context's version and extensions do not allow
rendering to the texture but the implementation is capable.
New Procedures and Functions
None
New Tokens
Accepted as a value for <pname> for the TexParameter{if} and
TexParameter{if}v commands and for the <value> parameter of
GetTexParameter{if}v:
GL_RENDERABILITY_VALIDATION_ANGLE 0x9EA0
Additions to the OpenGL Specification
None.
New Behavior
Additions to Chapter 3 of the OpenGL ES 2.0 Specification (Rasterization)
Add a new row to Table 3.10 (Texture parameters and their values):
Name | Type | Legal Values
------------------------------------------------------------
RENDERABILITY_VALIDATION_ANGLE | bool | TRUE, FALSE
Add a new section 3.7.x (Texture Usage) before section 3.7.12 and
renumber the subsequent sections:
"3.7.x Texture Usage
Texture renderability validation can be controled via the
RENDERABILITY_VALIDATION_ANGLE value for the <pname> argument to
TexParameter{if}[v].
Possible values for <params> when <pname> is TEXTURE_USAGE_ANGLE are:
TRUE - the default. Renderability validation is unchanged.
FALSE - Renderability of the texture becomes implementation dependent.
The implementation will allow rendering to the format if it is
capable."
