From 98ae83d5cc73b61826823c915b5c59746c2e85c7 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Wed, 12 Mar 2008 10:39:25 +0000 Subject: gallium: Add TEX_FILTER_ANISO img filter Hardware almost universally expects us to set a special filtering mode when anisotropic filtering is enabled, as opposed to varying a max-aniso values. Do this once in the state tracker & simplify the driver code. --- src/mesa/state_tracker/st_atom_sampler.c | 4 ++++ 1 file changed, 4 insertions(+) (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 1babba9b4f..d376480c91 100644 --- a/src/mesa/state_tracker/st_atom_sampler.c +++ b/src/mesa/state_tracker/st_atom_sampler.c @@ -160,6 +160,10 @@ update_samplers(struct st_context *st) #endif sampler->max_anisotropy = texobj->MaxAnisotropy; + if (sampler->max_anisotropy > 1.0) { + sampler->min_img_filter = PIPE_TEX_FILTER_ANISO; + sampler->mag_img_filter = PIPE_TEX_FILTER_ANISO; + } /* only care about ARB_shadow, not SGI shadow */ if (texobj->CompareMode == GL_COMPARE_R_TO_TEXTURE) { -- cgit v1.2.3
