CSO¶

+

CSO, Constant State Objects, are a core part of Gallium’s API.

+

CSO work on the principle of reusable state; they are created by filling +out a state object with the desired properties, then passing that object +to a context. The context returns an opaque context-specific handle which +can be bound at any time for the desired effect.

Notes¶

+
+

flatshade¶

+

The actual interpolated shading algorithm is obviously +implementation-dependent, but will usually be Gourard for most hardware.

+
+
+

bypass_vs_clip_and_viewport¶

+

When set, this implies that vertices are pre-transformed for the viewport, and +will not be run through the vertex shader. Note that implementations may still +clip away vertices that are not visible.

+
+
+

flatshade_first¶

+

There are several important exceptions to the specification of this rule.

+
    +
  • PIPE_PRIMITIVE_POLYGON: The provoking vertex is always the first vertex. +If the caller wishes to change the provoking vertex, they merely need to +rotate the vertices themselves.
    • +
  • PIPE_PRIMITIVE_QUAD, PIPE_PRIMITIVE_QUAD_STRIP: This option has no effect.
    • +
  • PIPE_PRIMITIVE_TRIANGLE_FAN: When set, the provoking vertex is the second +vertex, not the first. This permits each segment of the fan to have a +different color.

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.
