From 50f76b9d9b4b17940798b44233b9b5af2f932117 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Mon, 15 Jan 2007 14:20:21 +0000 Subject: [PATCH] Correctly initialize current attribute sizes. Some legacy attributes (eg color) have an initial value other than {0,0,0,1} which means that their initial size != 1 either. --- src/mesa/vbo/vbo_context.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) diff --git a/src/mesa/vbo/vbo_context.c b/src/mesa/vbo/vbo_context.c index 165e32da8a8..65998e7ff75 100644 --- a/src/mesa/vbo/vbo_context.c +++ b/src/mesa/vbo/vbo_context.c @@ -47,6 +47,14 @@ extern void _tnl_draw_prims( GLcontext *ctx, #define NR_GENERIC_ATTRIBS 16 #define NR_MAT_ATTRIBS 12 +static GLuint check_size( const GLfloat *attr ) +{ + if (attr[3] != 1.0) return 4; + if (attr[2] != 0.0) return 3; + if (attr[1] != 0.0) return 2; + return 1; +} + static void init_legacy_currval(GLcontext *ctx) { struct vbo_context *vbo = vbo_context(ctx); @@ -63,7 +71,7 @@ static void init_legacy_currval(GLcontext *ctx) /* Size will have to be determined at runtime: */ - cl->Size = 1; + cl->Size = check_size(ctx->Current.Attrib[i]); cl->Stride = 0; cl->StrideB = 0; cl->Enabled = 1; @@ -88,7 +96,6 @@ static void init_generic_currval(GLcontext *ctx) /* This will have to be determined at runtime: */ cl->Size = 1; - cl->Type = GL_FLOAT; cl->Ptr = (const void *)ctx->Current.Attrib[VERT_ATTRIB_GENERIC0 + i]; cl->Stride = 0; -- 2.30.2
