Description:
|
|
|
|
Texture border clamp cases test functionality added in
|
|
EXT_texture_border_clamp extension. Tests set up a texture with a certain
|
|
format, set border color to certain value, set one or more wrapping modes to
|
|
CLAMP_TO_BORDER, and then proceed to render the texture to screen. The
|
|
rendering result is then verified. Test cases also generate a reference image
|
|
which may be useful when evaluating results.
|
|
|
|
In formats.* subgroup, all GLES31 texture formats are tested. Each format is
|
|
tested with power-of-two and non-power-of-two texture sizes using NEAREST and
|
|
LINEAR filtering, and texture-gather fetching.
|
|
|
|
In range_clamp.* subgroup, border color components are set to values that are
|
|
not in the representable range of the internal format. The effective value is
|
|
expected to be clamped to the valid range.
|
|
|
|
In sampler.* subgroup, texture border color and wrapping mode are set using
|
|
a sampler state.
|
|
|
|
In per_axis_wrap_mode.*, texture wrap mode is not same in all S, T, and R
|
|
directions. Wrapping is tested for 2D and 3D textures with multiple formats
|
|
and with different sampling modes.
|
|
|
|
In depth_compare_mode.*, depth texture border values are tested with compare
|
|
mode set to COMPARE_REF_TO_TEXTURE.
|
|
|
|
In unused_channels.*, border color has non-zero values in components that are
|
|
not representable in the target formats. These components are expected to have
|
|
no effect.
