Rasterizer discard tests
|
|
|
|
Tests:
|
|
+ dEQP-GLES3.functional.rasterizer_discard.*
|
|
|
|
Includes:
|
|
+ Correct discarding of following operations are tested:
|
|
- All primitive draw modes
|
|
- Color clears & writes
|
|
- Depth clears & writes
|
|
- Stencil clears & writes
|
|
+ Following test cases are created:
|
|
- Discard test for default framebuffer
|
|
- Discard test for default framebuffer with scissor test enabled
|
|
- Discard test for a framebuffer object
|
|
|

Description:
|
|
|
|
Rasterizer discard functionality is tested by first clearing color, depth
|
|
and stencil buffers to initial values. Next, rasterizer discarding is
|
|
enabled, and an operation is performed. Rasterizer discarding is disabled
|
|
afterwards. For depth and stencil clears, series of primitives are drawn
|
|
to make sure that the buffer clear operations were ignored.
|
|
|
|
Finally, framebuffer pixels are read. If red color is present or blue
|
|
color is not present, the performed operation was not discarded according
|
|
to specification and the test fails.
|
|
|
|
This procedure is performed for both the default framebuffer and an FBO
|
|
with color, depth and stencil attachments. Additionally, default
|
|
framebuffer discards are tested with scissor test enabled.
