      Context¶

      -

      The context object represents the purest, most directly accessible, abilities -of the device’s 3D rendering pipeline.

      -
      -

      Methods¶

      -
      -

      CSO State¶

      -

      All CSO state is created, bound, and destroyed, with triplets of methods that -all follow a specific naming scheme. For example, create_blend_state, -bind_blend_state, and destroy_blend_state.

      -

      CSO objects handled by the context object:

      -
        -
      • Blend: *_blend_state
        • -
      • Sampler: These are special; they can be bound to either vertex or -fragment samplers, and they are bound in groups. -bind_fragment_sampler_states, bind_vertex_sampler_states
        • -
      • Rasterizer: *_rasterizer_state
        • -
      • Depth, Stencil, & Alpha: *_depth_stencil_alpha_state
        • -
      • Shader: These have two sets of methods. *_fs_state is for -fragment shaders, and *_vs_state is for vertex shaders.
        • -
      -
      -
      -

      Resource Binding State¶

      -

      This state describes how resources in various flavours (textures, -buffers, surfaces) are bound to the driver.

      -
        -
      • set_constant_buffer
        • -
      • set_framebuffer_state
        • -
      • set_fragment_sampler_textures
        • -
      • set_vertex_sampler_textures
        • -
      • set_vertex_buffers
        • -
      -
      -
      -

      Non-CSO State¶

      -

      These pieces of state are too small, variable, and/or trivial to have CSO -objects. They all follow simple, one-method binding calls, e.g. -set_edgeflags.

      -
        -
      • set_edgeflags
        • -
      • set_blend_color
        • -
      • set_clip_state
        • -
      • set_polygon_stipple
        • -
      • set_scissor_state
        • -
      • set_viewport_state
        • -
      • set_vertex_elements
        • -
      -
      -
      -

      Clearing¶

      -

      clear initializes some or all of the surfaces currently bound to -the framebuffer to particular RGBA, depth, or stencil values.

      -

      Clear is one of the most difficult concepts to nail down to a single -interface and it seems likely that we will want to add additional -clear paths, for instance clearing surfaces not bound to the -framebuffer, or read-modify-write clears such as depth-only or -stencil-only clears of packed depth-stencil buffers.

      -
      -
      -

      Drawing¶

      -

      draw_arrays

      -

      draw_elements

      -

      draw_range_elements

      -
      -
      -

      Queries¶

      -

      Queries gather some statistic from the 3D pipeline over one or more -draws. Queries may be nested, though no state tracker currently -exercises this.

      -

      Queries can be created with create_query and deleted with -destroy_query. To enable a query, use begin_query, and when finished, -use end_query to stop the query. Finally, get_query_result is used -to retrieve the results.

      -
      -
      -

      Flushing¶

      -

      flush

      -
      -
      -

      Resource Busy Queries¶

      -

      is_texture_referenced

      -

      is_buffer_referenced

      -
      -
      -

      Blitting¶

      -

      These methods emulate classic blitter controls. They are not guaranteed to be -available; if they are set to NULL, then they are not present.

      -

      These methods operate directly on pipe_surface objects, and stand -apart from any 3D state in the context. Blitting functionality may be -moved to a separate abstraction at some point in the future.

      -

      surface_fill performs a fill operation on a section of a surface.

      -

      surface_copy blits a region of a surface to a region of another surface, -provided that both surfaces are the same format. The source and destination -may be the same surface, and overlapping blits are permitted.

      -

      The interfaces to these calls are likely to change to make it easier -for a driver to batch multiple blits with the same source and -destination.

      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.

      Depth, Stencil, & Alpha¶

      -

      These three states control the depth, stencil, and alpha tests, used to -discard fragments that have passed through the fragment shader.

      -

      Traditionally, these three tests have been clumped together in hardware, so -they are all stored in one structure.

      -

      During actual execution, the order of operations done on fragments is always:

      -
        -
      • Stencil
        • -
      • Depth
        • -

      -
      bypass_vs_clip_and_viewport
      -

      -
      flatshade_first
      -
      Whether the first vertex should be the provoking vertex, for most -primitives. If not set, the last vertex is the provoking vertex.
      -
      gl_rasterization_rules
      -
      Whether the rasterizer should use (0.5, 0.5) pixel centers. When not set, -the rasterizer will use (0, 0) for pixel centers.

      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; the provoking vertex is always the last vertex.
        • -
      • 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.

      What is Gallium?¶

      -

      Gallium is essentially an API for writing graphics drivers in a largely -device-agnostic fashion. It provides several objects which encapsulate the -core services of graphics hardware in a straightforward manner.

      TGSI¶

      -

      TGSI, Tungsten Graphics Shader Instructions, is an intermediate language -for describing shaders. Since Gallium is inherently shaderful, shaders are -an important part of the API. TGSI is the only intermediate representation -used by all drivers.

      Declaration Semantic¶

      -
      -

      Follows Declaration token if Semantic bit is set.

      -

      Since its purpose is to link a shader with other stages of the pipeline, -it is valid to follow only those Declaration tokens that declare a register -either in INPUT or OUTPUT file.

      -

      SemanticName field contains the semantic name of the register being declared. -There is no default value.

      -

      SemanticIndex is an optional subscript that can be used to distinguish -different register declarations with the same semantic name. The default value -is 0.

      -

      The meanings of the individual semantic names are explained in the following -sections.

      TGSI_SEMANTIC_POSITION¶

      -

      Position, sometimes known as HPOS or WPOS for historical reasons, is the -location of the vertex in space, in (x, y, z, w) format. x, y, and z -are the Cartesian coordinates, and w is the homogenous coordinate and used -for the perspective divide, if enabled.

      -

      As a vertex shader output, position should be scaled to the viewport. When -used in fragment shaders, position will —

      -

      XXX — wait a minute. Should position be in [0,1] for x and y?

      -

      XXX additionally, is there a way to configure the perspective divide? it’s -accelerated on most chipsets AFAIK...

      -

      Position, if not specified, usually defaults to (0, 0, 0, 1), and can -be partially specified as (x, y, 0, 1) or (x, y, z, 1).

      -

      XXX usually? can we solidify that?

      -
      -
      -

      TGSI_SEMANTIC_COLOR¶

      -

      Colors are used to, well, color the primitives. Colors are always in -(r, g, b, a) format.

      -

      If alpha is not specified, it defaults to 1.

      -
      -
      -

      TGSI_SEMANTIC_BCOLOR¶

      -

      Back-facing colors are only used for back-facing polygons, and are only valid -in vertex shader outputs. After rasterization, all polygons are front-facing -and COLOR and BCOLOR end up occupying the same slots in the fragment, so -all BCOLORs effectively become regular COLORs in the fragment shader.

      -
      -
      -

      TGSI_SEMANTIC_FOG¶

      -

      The fog coordinate historically has been used to replace the depth coordinate -for generation of fog in dedicated fog blocks. Gallium, however, does not use -dedicated fog acceleration, placing it entirely in the fragment shader -instead.

      -

      The fog coordinate should be written in (f, 0, 0, 1) format. Only the first -component matters when writing from the vertex shader; the driver will ensure -that the coordinate is in this format when used as a fragment shader input.

      -
      -
      -

      TGSI_SEMANTIC_PSIZE¶

      -

      PSIZE, or point size, is used to specify point sizes per-vertex. It should -be in (p, n, x, f) format, where p is the point size, n is the minimum -size, x is the maximum size, and f is the fade threshold.

      -

      XXX this is arb_vp. is this what we actually do? should double-check...

      -

      When using this semantic, be sure to set the appropriate state in the -Rasterizer first.

      -
      -
      -

      TGSI_SEMANTIC_GENERIC¶

      -

      Generic semantics are nearly always used for texture coordinate attributes, -in (s, t, r, q) format. t and r may be unused for certain kinds -of lookups, and q is the level-of-detail bias for biased sampling.

      -

      These attributes are called “generic” because they may be used for anything -else, including parameters, texture generation information, or anything that -can be stored inside a four-component vector.

      TGSI_SEMANTIC_NORMAL¶

      -

      XXX no clue.

      -
      -
      -

      TGSI_SEMANTIC_FACE¶

      -

      FACE is the facing bit, to store the facing information for the fragment -shader. (f, 0, 0, 1) is the format. The first component will be positive -when the fragment is front-facing, and negative when the component is -back-facing.
