From 493a1bb822f80f48cf284cb572acb5dd393a07e1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Fonseca?= Date: Tue, 20 Apr 2010 10:22:28 +0200 Subject: [PATCH] gallium/docs: Make it clear that minIndex, maxIndex is exclusively a index buffer characteristic. Unlike the indexBias which is specific to a draw call. This are the semantics of both D3D and GL ARB_draw_elements_base_vertex extension. --- src/gallium/docs/source/context.rst | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/gallium/docs/source/context.rst b/src/gallium/docs/source/context.rst index 69e0fccc03c..c82e681a254 100644 --- a/src/gallium/docs/source/context.rst +++ b/src/gallium/docs/source/context.rst @@ -156,6 +156,9 @@ as indices to fetch vertex attributes. ``indexBias`` is a value which is added to every index read from the index buffer before fetching vertex attributes. +``minIndex`` and ``maxIndex`` describe minimum and maximum index contained in +the index buffer. + If a given vertex element has ``instance_divisor`` set to 0, it is said it contains per-vertex data and effective vertex attribute address needs to be recalculated for every index. -- 2.30.2
