Author: Brian Paul <[email protected]> Date: Mon Sep 21 16:07:14 2009 -0600 vbo: disable the GL_ARB_draw_elements_base_vertex rebase path This was introduced with commit 92d7ed8a20d4a018ce5324e6537ae7b478b9e5bf. It causes rendering of stray polygons (with sw rendering at least) when running the OGL Distilled / Picking demo (click on an object). This needs additional debugging to fix/restore. Found one suspect thing: in _tnl_draw_prims() there's some mixed signed/ unsigned arithmetic/comparing at line 422 that may be incorrect. --- src/mesa/vbo/vbo_rebase.c | 5 ++++- 1 files changed, 4 insertions(+), 1 deletions(-) diff --git a/src/mesa/vbo/vbo_rebase.c b/src/mesa/vbo/vbo_rebase.c index 799a25f..55a82ee 100644 --- a/src/mesa/vbo/vbo_rebase.c +++ b/src/mesa/vbo/vbo_rebase.c @@ -127,7 +127,10 @@ void vbo_rebase_prims( GLcontext *ctx, _mesa_printf("%s %d..%d\n", __FUNCTION__, min_index, max_index); - if (ib && ctx->Extensions.ARB_draw_elements_base_vertex) { + /* XXX this path is disabled for now. + * There's rendering corruption in some apps when it's enabled. + */ + if (0 && ib && ctx->Extensions.ARB_draw_elements_base_vertex) { /* If we can just tell the hardware or the TNL to interpret our * indices with a different base, do so. */ _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
