-
-
-OVERVIEW
-
-The t_dd_imm_* files form a set of templates to produce driver -
-specific software tnl modules for a small subset of transformation and
-lighting states.
-
-The approach is quite different to the large vertex buffers of the
-src/tnl module, and is based around a cache of four recent vertices
-and a 'current' vertex which is updated directly from the Color,
-Normal, Texcoord, SecondaryColor and Fog entrypoints.
-
-The current vertex is actually a composite of the ctx->Current values
-and a partial hardware vertex maintained where the hardware values
-differ from those in ctx->Current. For example, clamped color values
-are kept in the hardware vertex, while texcoords remain in
-ctx->Current.
-
-A crude diagram:
-
- +--------------+ +-------------------+
- | ctx->Current | | Current-HW-vertex |
- +--------------+ +-------------------+
- \ /
- \ /
- \ /

- --------- --------

- | vert-0 | | vert-1 | | vert-2 | | vert-3 |
- +--------+ +--------+ +--------+ +--------+
- |

- v
-
- DMA
-
-
-Here values from ctx->Current and current-HW-vertex are merged to
-build vert-2, which is then dumped to hardware (DMA). A state machine
-determines which vertex is built in turn, and how the vertices are
-used to present primitives to hardware. These actions all occur
-during a call to Vertex{234}f{v}.
-
-Each vert-n includes clip coordinates and a clipmask in addition to
-the hardware (window) coordinates. This information allows clipping
-to take place directly on these vertices, if need be.
-
-t_dd_imm_capi.h
-
- Color{34}{fub}{v}() implementations. These update both
- ctx->Current (unclamped float colors) and current-HW-vertex
- with hardware-specific color values (typically unsigned
- bytes).
-
- When lighting is enabled, the functions from src/api_noop.c
- should be used, which just update ctx->Current. (The
- current-hw-vertex colors are produced from lighting, which is
- keyed to Normal3f).
-
-t_dd_imm_vb.c
-
- Support functions for clipping and fallback. See
- t_dd_imm_primtmp.h.
-
-t_dd_imm_napi.c
-t_dd_imm_napi.h
-
- Versions of Normal3f{v} to perform lighting with one or more
- infinite lights. Updates ctx->Current.Normal and the current
- HW colors.
-
- When lighting is disabled, use the functions from api_noop.c
- instead.
-
-
-t_dd_imm_primtmp.h
-
- State machine to control emission of vertices and primitives
- to hardware. Called indirectly from Vertex{234}f{v}. Capable
- of supporting hardware strip and fan primitives, and of
- decomposing to discreet primitives for clipping or fallback,
- or where the native primitive is unavailable.
-
-t_dd_imm_tapi.h
-
- Implementations of TexCoord{v} and MultiTexCoord4f{v}ARB to
- fire a callback when transitioning to projective texture.
- Most drivers will need to change vertex format at this point,
- some may need to enable a software rasterization fallback.
-
-t_dd_imm_vapi.h
-
- Implementations of Vertex{234}f{v}. These perform
- transformation and cliptesting on their arguments, then jump
- into the state machine implemented in primtmp.h.
-
-t_dd_imm_vertex.h
-
- Support functions for building and clip-interpolating hardware
- vertices. Called from primtmp.h.
