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/main/buffers.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/mesa/main/buffers.c') diff --git a/src/mesa/main/buffers.c b/src/mesa/main/buffers.c index 0fba73b3c2..2252bbd4c5 100644 --- a/src/mesa/main/buffers.c +++ b/src/mesa/main/buffers.c @@ -508,8 +508,9 @@ set_color_output(GLcontext *ctx, GLuint output, GLenum buffer, /* Set per-FBO state */ fb->ColorDrawBuffer[output] = buffer; fb->_ColorDrawBufferMask[output] = destMask; - /* not really needed, will be set later */ - fb->_NumColorDrawBuffers[output] = 0; + + /* this will be computed later, but zero to be safe */ + fb->_NumColorDrawBuffers = 0; if (fb->Name == 0) { /* Only set the per-context DrawBuffer state if we're currently -- cgit v1.2.3
