Texture unit usage tests
|
|
|
|
Tests:
|
|
+ dEQP-GLES2.functional.texture.units.*
|
|
|
|
Includes:
|
|
+ Use of multiple units simultaneously:
|
|
- 1, 2, 4, 8
|
|
- all available
|
|
+ Mixed texture formats
|
|
+ Mixed texture types
|
|
+ Mixed texture parameters
|

Description:
|
|
|
|
For each texture unit a 2D or cube map texture is generated. Shader samples all
|
|
textures and adds scaled lookup values together to yield a value in range 0..1
|
|
for each output component.
|
|
|
|
For each texture a separate coordinate array is generated, yielding different
|
|
sample points. Simple quad is rendered with a fragment shader that adds texture
|
|
lookup results together. Resulting image is compared against a reference image
|
|
produced by a reference renderer.
