Pixel Buffer Object tests
Tests:
+ dEQP-GLES3.functional.pbo.*
Includes:
+ Creating and destroying pixel pack and unpack buffers
+ Writing buffer data using glBufferData() and glBufferSubData()
+ Mapping PBOs
+ Reading pixels to pixel pack buffer
+ Copying between pixel buffer objects (2012.3)
+ Texture pack modes used in combination with pixel pack buffers
Excludes:
+ Specifying textures from PBOs
- Fully covered in texture specification tests
+ Negative API tests
- Will be added in 2012.3
+ Buffer queries
- Will be added in 2012.4
Description:
Pixel buffer object tests create pixel pack buffer or unpack buffer. Data is
written to buffer either using glBuffer(Sub)Data() or mapping buffer. After
the write data is verified to be correct by mapping the buffer. Additionally,
for pixel pack buffers readpixels is issued with PBO bound. The readpixels result
is verified by doing the same operation without pack buffer and then comparing
the results.
