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 | - +--------------+ +-------------------+ - \ / - \ / - \ / - \ / - --------- -------- - | | - v v - +--------+ +--------+ +--------+ +--------+ - | 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.
