From: Brian Paul Date: Thu, 6 Apr 2006 04:23:58 +0000 (+0000) Subject: Replace MESA_FORMAT_DEPTH_COMPONENT_FLOAT32 with 32-bit integer format. X-Git-Tag: 062012170305~21158 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a9bcf751030895494fc098f8d0ff56b2496bd993;p=profile%2Fivi%2Fmesa.git Replace MESA_FORMAT_DEPTH_COMPONENT_FLOAT32 with 32-bit integer format. This allows render to depth texture (we don't support floating pt. Z buffers). Rename MESA_FORMAT_DEPTH_COMPONENT16/32 as MESA_FORMAT_Z16/32. Software fallback for glCopyTexImage now uses integer temporary image instead of float, eliminates a lot of float/int conversions. --- diff --git a/src/mesa/drivers/dri/i915/intel_tex.c b/src/mesa/drivers/dri/i915/intel_tex.c index 4bd7f92..d2bf9d0 100644 --- a/src/mesa/drivers/dri/i915/intel_tex.c +++ b/src/mesa/drivers/dri/i915/intel_tex.c @@ -572,7 +572,7 @@ intelChooseTextureFormat( GLcontext *ctx, GLint internalFormat, case GL_DEPTH_COMPONENT16: case GL_DEPTH_COMPONENT24: case GL_DEPTH_COMPONENT32: - return &_mesa_texformat_depth_component16;
