From fdb07636f2e6324c5250cd5ee97778b7f5933bea Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 22 Feb 2005 22:36:31 +0000 Subject: Added __glExtensionBiIsEnabled and __GLXcontext::gl_extension_bits. This enables libGL to query which extension are exported to applications. Refactored array-query functionality (from glGet*v) in src/glx/x11/single2.c. Massive re-write of indirect vertex array support. The most noticable effect is that glDrawElements now generates DrawArrays protocol. The side-effects (and the main reasons for the re-work) are that it is much easier to add support for new arrays (e.g., GL_VERTEX_ATTRIB_ARRAY, GL_WEIGHT_ARRAY_ARB, etc.) and it is much easier to add support for the new DrawArrays protocol (required to support ARB_vertex_buffer_object). These changes were primarilly tested with progs/demos/isosurf. --- src/glx/x11/indirect_vertex_array.h | 55 +++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 src/glx/x11/indirect_vertex_array.h (limited to 'src/glx/x11/indirect_vertex_array.h') diff --git a/src/glx/x11/indirect_vertex_array.h b/src/glx/x11/indirect_vertex_array.h new file mode 100644 index 0000000000..5eae8a5a6e --- /dev/null +++ b/src/glx/x11/indirect_vertex_array.h @@ -0,0 +1,55 @@ +/* + * (C) Copyright IBM Corporation 2004, 2005 + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sub license, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.
