From a4af3e5ab3fa0f45c25673c93d802cdff087145c Mon Sep 17 00:00:00 2001 From: Brian Date: Wed, 20 Jun 2007 11:01:04 -0600 Subject: Effectively disable _TexEnvProgram before calling _swrast_DrawPixels(). It's OK to use _TexEnvProgram regardless of the texture state, but if fog is also enabled, the fragment program is lacking the actual fog computation so fogging doesn't appear. Fixing this might involve a new _MaintainFogProgram field and related code. For now, just disable the _TexEnvProgram and let swrast handle everything. --- src/mesa/drivers/dri/i915/intel_pixel.c | 18 +++++++++++++++--- src/mesa/drivers/dri/i915tex/intel_pixel_draw.c | 14 +++++++++++++- 2 files changed, 28 insertions(+), 4 deletions(-) (limited to 'src/mesa/drivers') diff --git a/src/mesa/drivers/dri/i915/intel_pixel.c b/src/mesa/drivers/dri/i915/intel_pixel.c index 535cbfcb26..a52a81bf13 100644 --- a/src/mesa/drivers/dri/i915/intel_pixel.c +++ b/src/mesa/drivers/dri/i915/intel_pixel.c @@ -440,9 +440,21 @@ intelDrawPixels( GLcontext *ctx, fprintf(stderr, "%s\n", __FUNCTION__); if (!intelTryDrawPixels( ctx, x, y, width, height, format, type, - unpack, pixels )) - _swrast_DrawPixels( ctx, x, y, width, height, format, type, - unpack, pixels ); + unpack, pixels )) { + if (ctx->FragmentProgram._Current == + ctx->FragmentProgram._TexEnvProgram) { + /* don't want the i915 texenv program to be applied to DrawPixels */ + struct gl_fragment_program *fpSave = ctx->FragmentProgram._Current; + ctx->FragmentProgram._Current = NULL; + _swrast_DrawPixels( ctx, x, y, width, height, format, type, + unpack, pixels ); + ctx->FragmentProgram._Current = fpSave; + } + else { + _swrast_DrawPixels( ctx, x, y, width, height, format, type, + unpack, pixels ); + } + } } diff --git a/src/mesa/drivers/dri/i915tex/intel_pixel_draw.c b/src/mesa/drivers/dri/i915tex/intel_pixel_draw.c index 10a079896a..46480da1b1 100644 --- a/src/mesa/drivers/dri/i915tex/intel_pixel_draw.c +++ b/src/mesa/drivers/dri/i915tex/intel_pixel_draw.c @@ -363,5 +363,17 @@ intelDrawPixels(GLcontext * ctx, if (INTEL_DEBUG & DEBUG_PIXEL) _mesa_printf("%s: fallback to swrast\n", __FUNCTION__); - _swrast_DrawPixels(ctx, x, y, width, height, format, type, unpack, pixels); + if (ctx->FragmentProgram._Current == + ctx->FragmentProgram._TexEnvProgram) { + /* don't want the i915 texenv program to be applied to DrawPixels */ + struct gl_fragment_program *fpSave = ctx->FragmentProgram._Current; + ctx->FragmentProgram._Current = NULL; + _swrast_DrawPixels( ctx, x, y, width, height, format, type, + unpack, pixels ); + ctx->FragmentProgram._Current = fpSave; + } + else { + _swrast_DrawPixels( ctx, x, y, width, height, format, type, + unpack, pixels ); + } } -- cgit v1.2.3
