Sampler

Texture units have many options for selecting texels from loaded textures; this state controls an individual texture unit’s texel-sampling settings.

Texture coordinates are always treated as four-dimensional, and referred to with the traditional (S, T, R, Q) notation.

Members

XXX undocumented compare_mode, compare_func

wrap_s

How to wrap the S coordinate. One of PIPE_TEX_WRAP.

wrap_t

How to wrap the T coordinate. One of PIPE_TEX_WRAP.

wrap_r

How to wrap the R coordinate. One of PIPE_TEX_WRAP.

min_img_filter

The filter to use when minifying texels. One of PIPE_TEX_FILTER.

min_mip_filter

The filter to use when minifying mipmapped textures. One of PIPE_TEX_FILTER.

mag_img_filter

The filter to use when magnifying texels. One of PIPE_TEX_FILTER.

normalized_coords

Whether the texture coordinates are normalized. If normalized, they will always be in [0, 1]. If not, they will be in the range of each dimension of the loaded texture.

prefilter

XXX From the Doxy, “weird sampling state exposed by some APIs.” Refine.

lod_bias

The bias to apply to the level of detail.

min_lod

Minimum level of detail, used to clamp LoD after bias.

max_lod

Maximum level of detail, used to clamp LoD after bias.

border_color

RGBA color used for out-of-bounds coordinates.

max_anisotropy

Maximum filtering to apply anisotropically to textures. Setting this to 1.0 effectively disables anisotropic filtering.
