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/mesa/state_tracker/st_atom_sampler.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mesa') diff --git a/src/mesa/state_tracker/st_atom_sampler.c b/src/mesa/state_tracker/st_atom_sampler.c index 9d63f1c6ab..a8262a5e1a 100644 --- a/src/mesa/state_tracker/st_atom_sampler.c +++ b/src/mesa/state_tracker/st_atom_sampler.c @@ -211,7 +211,7 @@ update_samplers(struct st_context *st) teximg ? teximg->_BaseFormat : GL_RGBA, sampler->border_color); - sampler->max_anisotropy = texobj->MaxAnisotropy; + sampler->max_anisotropy = (texobj->MaxAnisotropy == 1.0 ? 0 : (GLuint)texobj->MaxAnisotropy); /* only care about ARB_shadow, not SGI shadow */ if (texobj->CompareMode == GL_COMPARE_R_TO_TEXTURE) { -- cgit v1.2.3
