From a96308c37db0bc0086a017d318bc3504aa5f0b1a Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Mon, 30 Oct 2000 13:31:59 +0000 Subject: Replace the flags Mesa was using for ctx->NewState with a new set based on the GL attribute groups. Introduced constants describing the circumstances under which some key derived values can change: _SWRAST_NEW_RASTERMASK -- ctx->RasterMask _SWRAST_NEW_TRIANGLE -- The software rasterizer's triangle function _DD_NEW_FEEDBACK -- the 'DD_FEEDBACK' bit in ctx->TriangleCaps These are helpful in deciding whether you need to recalculate state if your recalculation involves reference to a derived value. --- src/mesa/main/buffers.c | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) (limited to 'src/mesa/main/buffers.c') diff --git a/src/mesa/main/buffers.c b/src/mesa/main/buffers.c index 7d6528291b..33e7bc0016 100644 --- a/src/mesa/main/buffers.c +++ b/src/mesa/main/buffers.c @@ -1,4 +1,4 @@ -/* $Id: buffers.c,v 1.15 2000/10/28 18:34:48 brianp Exp $ */ +/* $Id: buffers.c,v 1.16 2000/10/30 13:31:59 keithw Exp $ */ /* * Mesa 3-D graphics library @@ -51,6 +51,8 @@ _mesa_ClearIndex( GLfloat c ) GET_CURRENT_CONTEXT(ctx); ASSERT_OUTSIDE_BEGIN_END_AND_FLUSH(ctx, "glClearIndex"); ctx->Color.ClearIndex = (GLuint) c; + ctx->NewState |= _NEW_COLOR; + if (!ctx->Visual.RGBAflag) { /* it's OK to call glClearIndex in RGBA mode but it should be a NOP */ (*ctx->Driver.ClearIndex)( ctx, ctx->Color.ClearIndex ); @@ -70,6 +72,7 @@ _mesa_ClearColor( GLclampf red, GLclampf green, ctx->Color.ClearColor[1] = CLAMP( green, 0.0F, 1.0F ); ctx->Color.ClearColor[2] = CLAMP( blue, 0.0F, 1.0F ); ctx->Color.ClearColor[3] = CLAMP( alpha, 0.0F, 1.0F ); + ctx->NewState |= _NEW_COLOR; if (ctx->Visual.RGBAflag) { GLchan r = (GLint) (ctx->Color.ClearColor[0] * CHAN_MAXF); @@ -469,7 +472,7 @@ _mesa_DrawBuffer( GLenum mode ) } ctx->Color.DrawBuffer = mode; - ctx->NewState |= NEW_RASTER_OPS; + ctx->NewState |= _NEW_COLOR; } @@ -527,7 +530,7 @@ _mesa_ReadBuffer( GLenum mode ) } ctx->Pixel.ReadBuffer = mode; - ctx->NewState |= NEW_RASTER_OPS; + ctx->NewState |= _NEW_PIXEL; } @@ -552,7 +555,7 @@ _mesa_ResizeBuffersMESA( void ) ctx->DrawBuffer->Height == (GLint) buf_height) return; - ctx->NewState |= NEW_RASTER_OPS; /* to update scissor / window bounds */ + ctx->NewState |= _NEW_BUFFERS; /* to update scissor / window bounds */ /* save buffer size */ ctx->DrawBuffer->Width = buf_width; -- cgit v1.2.3
