From ebe12d50064370e4ddec21a1e087b24295940319 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Fri, 12 Feb 2010 00:43:38 +0100 Subject: gallium: make max_anisotropy a unsigned bitfield member saves us a dword in sampler state, hw can't do non-integer aniso degree anyway. To allow aniso 1x (which seems of dubious value but some hardware (radeons) have such a mode, and even d3d allows specifiying it) redefine anisotropic filtering as disabled only if max_anistropy is 0. --- src/gallium/docs/source/cso/sampler.rst | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/gallium/docs/source') diff --git a/src/gallium/docs/source/cso/sampler.rst b/src/gallium/docs/source/cso/sampler.rst index 044ffffcb4f..77979fc44d1 100644 --- a/src/gallium/docs/source/cso/sampler.rst +++ b/src/gallium/docs/source/cso/sampler.rst @@ -45,4 +45,6 @@ border_color RGBA color used for out-of-bounds coordinates. max_anisotropy Maximum filtering to apply anisotropically to textures.
