From e90de7883a3bd9afd27ac83314f08cf9f03f60e3 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Sat, 29 Nov 2003 19:33:33 +0000 Subject: Fix generic/conventional vertex array glitches. Changed _NEW_ARRAY_ATTRIB_0 back to 0x10000 so that the conventional and generic enable bits do not alias. In ac_import.c test Array.Normal.Enabled instead of Array._Enabled & _NEW_ARRAY_COLOR0, etc. In t_array_import.c give priority for generic arrays over conventional arrays on an individual basis, not all or none. --- src/mesa/tnl/t_array_api.c | 21 ++++++-- src/mesa/tnl/t_array_import.c | 115 ++++++++++++++++++++++-------------------- 2 files changed, 77 insertions(+), 59 deletions(-) (limited to 'src/mesa/tnl') diff --git a/src/mesa/tnl/t_array_api.c b/src/mesa/tnl/t_array_api.c index f9f5fe9951..2b10a9d1c2 100644 --- a/src/mesa/tnl/t_array_api.c +++ b/src/mesa/tnl/t_array_api.c @@ -107,11 +107,16 @@ static void _tnl_draw_range_elements( GLcontext *ctx, GLenum mode, if (ctx->Array.LockCount) tnl->Driver.RunPipeline( ctx ); else { + /* The lower 16 bits represent the conventional arrays while the + * upper 16 bits represent the generic arrays.
