From ff73c783cc47361ff0dd819c82d067b4b85870dd Mon Sep 17 00:00:00 2001 From: Brian Date: Sun, 6 Jan 2008 10:43:20 -0700 Subject: Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835. These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this... --- src/mesa/swrast/s_buffers.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'src/mesa/swrast/s_buffers.c') diff --git a/src/mesa/swrast/s_buffers.c b/src/mesa/swrast/s_buffers.c index 90a56284c5..b74c4ab1c8 100644 --- a/src/mesa/swrast/s_buffers.c +++ b/src/mesa/swrast/s_buffers.c @@ -251,7 +251,7 @@ static void clear_color_buffers(GLcontext *ctx) { GLboolean masking; - GLuint i; + GLuint buf; if (ctx->Visual.rgbMode) { if (ctx->Color.ColorMask[0] && @@ -265,7 +265,7 @@ clear_color_buffers(GLcontext *ctx) } } else { - struct gl_renderbuffer *rb = ctx->DrawBuffer->_ColorDrawBuffers[0][0]; + struct gl_renderbuffer *rb = ctx->DrawBuffer->_ColorDrawBuffers[0]; const GLuint indexBits = (1 << rb->IndexBits) - 1; if ((ctx->Color.IndexMask & indexBits) == indexBits) { masking = GL_FALSE; @@ -275,8 +275,8 @@ clear_color_buffers(GLcontext *ctx) } } - for (i = 0; i < ctx->DrawBuffer->_NumColorDrawBuffers[0]; i++) { - struct gl_renderbuffer *rb = ctx->DrawBuffer->_ColorDrawBuffers[0][i]; + for (buf = 0; buf < ctx->DrawBuffer->_NumColorDrawBuffers; buf++) { + struct gl_renderbuffer *rb = ctx->DrawBuffer->_ColorDrawBuffers[buf]; if (ctx->Visual.rgbMode) { if (masking) { clear_rgba_buffer_with_masking(ctx, rb); @@ -331,7 +331,7 @@ _swrast_Clear(GLcontext *ctx, GLbitfield buffers) /* do software clearing here */ if (buffers) { - if (buffers & ctx->DrawBuffer->_ColorDrawBufferMask[0]) { + if (buffers & ctx->DrawBuffer->_NumColorDrawBuffers > 0) { clear_color_buffers(ctx); } if (buffers & BUFFER_BIT_DEPTH) { -- cgit v1.2.3
