Additionally it attempts to minimize the need * for execute-time fixup of these vertex lists, allowing them to be * cached on hardware. * * There are still some circumstances where this can be thwarted, for * example by building a list that consists of one very long primitive * (eg Begin(Triangles), 1000 vertices, End), and calling that list * from inside a different begin/end object (Begin(Lines), CallList, * End). * * In that case the code will have to replay the list as individual * commands through the Exec dispatch table, or fix up the copied * vertices at execute-time. * * The other case where fixup is required is when a vertex attribute * is introduced in the middle of a primitive. Eg: * Begin(Lines) * TexCoord1f() Vertex2f() * TexCoord1f() Color3f() Vertex2f() * End() * * If the current value of Color isn't known at compile-time, this * primitive will require fixup. * * * The list compiler currently doesn't attempt to compile lists * containing EvalCoord or EvalPoint commands. On encountering one of * these, compilation falls back to opcodes. * * This could be improved to fallback only when a mix of EvalCoord and * Vertex commands are issued within a single primitive. */ #include "glheader.h" #include "context.h" #include "dlist.h" #include "enums.h" #include "macros.h" #include "api_validate.h" #include "api_arrayelt.h" #include "vtxfmt.h" #include "t_save_api.h" /* * NOTE: Old 'parity' issue is gone, but copying can still be * wrong-footed on replay. */ static GLuint _save_copy_vertices( GLcontext *ctx, struct tnl_vertex_list *node ) { TNLcontext *tnl = TNL_CONTEXT( ctx );
