From 1e1aac034c986a08248861363c0baa27dc2ae2d5 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Mon, 13 Nov 2000 20:02:56 +0000 Subject: Cleanup of derived state calculation prior to seperating software T&L into a new directory. Specifically the handling of changes to lighting lighting space (light in model vs. light in eye) have been revamped. Moved several derived values used only by swrast into that directory. Removed direct calls to swrast_flush() from vbrender.c -- pushed into ctx->Driver.RenderFinish. Optimized flat-shading case in swrast_setup. --- src/mesa/swrast/s_points.c | 19 +++++++++++-------- 1 file changed, 11 insertions(+), 8 deletions(-) (limited to 'src/mesa/swrast/s_points.c') diff --git a/src/mesa/swrast/s_points.c b/src/mesa/swrast/s_points.c index 59fadfb8e9..e5360dff7d 100644 --- a/src/mesa/swrast/s_points.c +++ b/src/mesa/swrast/s_points.c @@ -1,4 +1,4 @@ -/* $Id: s_points.c,v 1.3 2000/11/10 17:45:16 brianp Exp $ */ +/* $Id: s_points.c,v 1.4 2000/11/13 20:02:57 keithw Exp $ */ /* * Mesa 3-D graphics library @@ -362,7 +362,8 @@ multitextured_rgba_point( GLcontext *ctx, SWvertex *vert ) static void antialiased_rgba_point( GLcontext *ctx, SWvertex *vert ) { - struct pixel_buffer *PB = SWRAST_CONTEXT(ctx)->PB; + SWcontext *swrast = SWRAST_CONTEXT(ctx); + struct pixel_buffer *PB = swrast->PB; const GLfloat radius = ctx->Point.Size * 0.5F; const GLfloat rmin = radius - 0.7071F; /* 0.7071 = sqrt(2)/2 */ const GLfloat rmax = radius + 0.7071F; @@ -421,7 +422,7 @@ antialiased_rgba_point( GLcontext *ctx, SWvertex *vert ) /* coverage is in [0,256] */ alpha = (alpha * coverage) >> 8; } - if (ctx->Texture._MultiTextureEnabled) { + if (swrast->_MultiTextureEnabled) { PB_WRITE_MULTITEX_PIXEL( PB, x,y,z, fog, red, green, blue, alpha, texcoord ); @@ -614,7 +615,8 @@ dist_atten_general_rgba_point( GLcontext *ctx, SWvertex *vert ) static void dist_atten_textured_rgba_point( GLcontext *ctx, SWvertex *vert ) { - struct pixel_buffer *PB = SWRAST_CONTEXT(ctx)->PB; + SWcontext *swrast = SWRAST_CONTEXT(ctx); + struct pixel_buffer *PB = swrast->PB; const GLfloat psize = ctx->Point.Size; GLfloat dist = attenuation_distance( ctx, vert->eye ); @@ -683,7 +685,7 @@ dist_atten_textured_rgba_point( GLcontext *ctx, SWvertex *vert ) for (iy = y0; iy <= y1; iy++) { for (ix = x0; ix <= x1; ix++) { - if (ctx->Texture._MultiTextureEnabled) { + if (swrast->_MultiTextureEnabled) { PB_WRITE_MULTITEX_PIXEL( PB, ix, iy, z, fog, red, green, blue, alpha, texcoord ); @@ -706,7 +708,8 @@ dist_atten_textured_rgba_point( GLcontext *ctx, SWvertex *vert ) static void dist_atten_antialiased_rgba_point( GLcontext *ctx, SWvertex *vert ) { - struct pixel_buffer *PB = SWRAST_CONTEXT(ctx)->PB; + SWcontext *swrast = SWRAST_CONTEXT(ctx); + struct pixel_buffer *PB = swrast->PB; const GLfloat psize = ctx->Point.Size; GLfloat dist = attenuation_distance( ctx, vert->eye ); @@ -775,7 +778,7 @@ dist_atten_antialiased_rgba_point( GLcontext *ctx, SWvertex *vert ) alpha = (alpha * coverage) >> 8; } alpha = (GLint) (alpha * alphaf); - if (ctx->Texture._MultiTextureEnabled) { + if (swrast->_MultiTextureEnabled) { PB_WRITE_MULTITEX_PIXEL( PB, x, y, z, fog, red, green, blue, alpha, texcoord ); @@ -906,7 +909,7 @@ _swrast_choose_point( GLcontext *ctx ) swrast->Point = antialiased_rgba_point; } else if (ctx->Texture._ReallyEnabled) { - if (ctx->Texture._MultiTextureEnabled || + if (swrast->_MultiTextureEnabled || ctx->Light.Model.ColorControl==GL_SEPARATE_SPECULAR_COLOR || ctx->Fog.ColorSumEnabled) { swrast->Point = multitextured_rgba_point; -- cgit v1.2.3
