OpenGL ES Extension ###
Dependencies
OpenGL ES 3.0 is required.
The extension is written against the OpenGL ES 3.2 specification.
Overview
This extension allows defined results when reading from a depth
texture that is bound as a read-only depth buffer.
IP Status
No known IP claims.
New Procedures and Functions
None
New Tokens
None
Additions to Chapter 8 of the OpenGL ES 3.2 Specification (Textures and
Samplers)
Added to the list of conditions in 8.14.2.1 (Rendering Feedback Loops):
"The texture is not a depth/stencil texture, or the value of
DEPTH_WRITEMASK is not FALSE."
Additions to Chapter 9 of the OpenGL ES 3.1 Specification (Framebuffers and
Framebuffer Objects)
Removed from the end of section in 9.3.1 (Rendering Feedback Loops):
"Also note that even if writing to a given texture is disabled (e.g. via the color,
depth, or stencil writemasks) during rendering, a feedback loop will still occur."
Added from the end of section in 9.3.1 (Rendering Feedback Loops):
"Note that if writing to a given depth texture is disabled (via the depth
writemask) during rendering, a feedback loop will not occur."
