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 "main/glheader.h" #include "main/bufferobj.h" #include "main/context.h" #include "main/dlist.h" #include "main/enums.h" #include "main/eval.h" #include "main/macros.h" #include "main/api_validate.h" #include "main/api_arrayelt.h" #include "main/vtxfmt.h" #include "main/dispatch.h" #include "vbo_context.h" #include "vbo_noop.h" #ifdef ERROR #undef ERROR #endif /* An interesting VBO number/name to help with debugging */ #define VBO_BUF_ID 12345 /* * NOTE: Old 'parity' issue is gone, but copying can still be * wrong-footed on replay. */ static GLuint _save_copy_vertices(struct gl_context *ctx, const struct vbo_save_vertex_list *node, const GLfloat * src_buffer) { struct vbo_save_context *save = &vbo_context(ctx)->save; const struct _mesa_prim *prim = &node->prim[node->prim_count - 1]; GLuint nr = prim->count; GLuint sz = save->vertex_size; const GLfloat *src = src_buffer + prim->start * sz; GLfloat *dst = save->copied.buffer; GLuint ovf, i; if (prim->end) return 0; switch (prim->mode) { case GL_POINTS: return 0; case GL_LINES: ovf = nr & 1; for (i = 0; i < ovf; i++) memcpy(dst + i * sz, src + (nr - ovf + i) * sz, sz * sizeof(GLfloat)); return i; case GL_TRIANGLES: ovf = nr % 3; for (i = 0; i < ovf; i++) memcpy(dst + i * sz, src + (nr - ovf + i) * sz, sz * sizeof(GLfloat)); return i; case GL_QUADS: ovf = nr & 3; for (i = 0; i < ovf; i++) memcpy(dst + i * sz, src + (nr - ovf + i) * sz, sz * sizeof(GLfloat)); return i; case GL_LINE_STRIP: if (nr == 0) return 0; else { memcpy(dst, src + (nr - 1) * sz, sz * sizeof(GLfloat)); return 1; } case GL_LINE_LOOP: case GL_TRIANGLE_FAN: case GL_POLYGON: if (nr == 0) return 0; else if (nr == 1) { memcpy(dst, src + 0, sz * sizeof(GLfloat)); return 1; } else { memcpy(dst, src + 0, sz * sizeof(GLfloat)); memcpy(dst + sz, src + (nr - 1) * sz, sz * sizeof(GLfloat)); return 2; } case GL_TRIANGLE_STRIP: case GL_QUAD_STRIP: switch (nr) { case 0: ovf = 0; break; case 1: ovf = 1; break; default: ovf = 2 + (nr & 1); break; } for (i = 0; i < ovf; i++) memcpy(dst + i * sz, src + (nr - ovf + i) * sz, sz * sizeof(GLfloat)); return i; default: assert(0); return 0; } } static struct vbo_save_vertex_store * alloc_vertex_store(struct gl_context *ctx) { struct vbo_save_context *save = &vbo_context(ctx)->save; struct vbo_save_vertex_store *vertex_store = CALLOC_STRUCT(vbo_save_vertex_store); /* obj->Name needs to be non-zero, but won't ever be examined more * closely than that.
