From 048765624598e6c60b9fe4dc82a72b7110f16715 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 19 Jun 2009 08:40:43 -0600 Subject: softpipe: return alpha=1 in shadow_compare() function The alpha value wasn't set at all before so we got unpredictable results. Note that we don't currently obey GL_DEPTH_TEXTURE_MODE in the state tracker. For now, we return the result in the default mode (r,r,r,1). --- src/gallium/drivers/softpipe/sp_tex_sample.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/gallium/drivers/softpipe') diff --git a/src/gallium/drivers/softpipe/sp_tex_sample.c b/src/gallium/drivers/softpipe/sp_tex_sample.c index adbd0cb7f0..5de358dae9 100644 --- a/src/gallium/drivers/softpipe/sp_tex_sample.c +++ b/src/gallium/drivers/softpipe/sp_tex_sample.c @@ -744,7 +744,9 @@ shadow_compare(uint compare_func, break; } + /* XXX returning result for default GL_DEPTH_TEXTURE_MODE = GL_LUMINANCE */ rgba[0][j] = rgba[1][j] = rgba[2][j] = (float) k; + rgba[3][j] = 1.0F; } -- cgit v1.2.3
