35 | /* Display list compiler attempts to store lists of vertices with the |
||
36 | * same vertex layout. Additionally it attempts to minimize the need |
||
37 | * for execute-time fixup of these vertex lists, allowing them to be |
||
38 | * cached on hardware. |
||
39 | * |
||
40 | * There are still some circumstances where this can be thwarted, for |
||
41 | * example by building a list that consists of one very long primitive |
||
42 | * (eg Begin(Triangles), 1000 vertices, End), and calling that list |
||
43 | * from inside a different begin/end object (Begin(Lines), CallList, |
||
44 | * End). |
||
45 | * |
||
46 | * In that case the code will have to replay the list as individual |
||
47 | * commands through the Exec dispatch table, or fix up the copied |
||
48 | * vertices at execute-time. |
||
49 | * |
||
50 | * The other case where fixup is required is when a vertex attribute |
||
51 | * is introduced in the middle of a primitive. Eg: |
||
52 | * Begin(Lines) |
||
53 | * TexCoord1f() Vertex2f() |
||
54 | * TexCoord1f() Color3f() Vertex2f() |
||
55 | * End() |
||
56 | * |
||
57 | * If the current value of Color isn't known at compile-time, this |
||
58 | * primitive will require fixup. |
||
59 | * |
||
60 | * |
||
61 | * The list compiler currently doesn't attempt to compile lists |
||
62 | * containing EvalCoord or EvalPoint commands. On encountering one of |
||
63 | * these, compilation falls back to opcodes. |
||
64 | * |
||
65 | * This could be improved to fallback only when a mix of EvalCoord and |
||
66 | * Vertex commands are issued within a single primitive. |
