From 594dab4769533afaeb30a588e1731a6753a93f0d Mon Sep 17 00:00:00 2001 From: Brian Date: Mon, 31 Mar 2008 14:14:30 -0600 Subject: gallium: move the test for bypass_vs into the vs_XXX_run() functions Also: 1. Added an identity_viewport flag to skip viewport transformation when it has no effect. Might also add an explicit bypass_viewport flag someday. 2. Separate the code for computing clip codes and doing the viewport transform. Predicate them separately. Note: even if bypass_vs is set, we still look at the shader to determine the number of inputs and outputs. --- src/gallium/auxiliary/draw/draw_context.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'src/gallium/auxiliary/draw/draw_context.c') diff --git a/src/gallium/auxiliary/draw/draw_context.c b/src/gallium/auxiliary/draw/draw_context.c index 10bf9f54c1..d0d5f66b37 100644 --- a/src/gallium/auxiliary/draw/draw_context.c +++ b/src/gallium/auxiliary/draw/draw_context.c @@ -228,6 +228,14 @@ void draw_set_viewport_state( struct draw_context *draw, { draw_do_flush( draw, DRAW_FLUSH_STATE_CHANGE ); draw->viewport = *viewport; /* struct copy */ + draw->identity_viewport = (viewport->scale[0] == 1.0f && + viewport->scale[1] == 1.0f && + viewport->scale[2] == 1.0f && + viewport->scale[3] == 1.0f && + viewport->translate[0] == 0.0f && + viewport->translate[1] == 0.0f && + viewport->translate[2] == 0.0f && + viewport->translate[3] == 0.0f); } -- cgit v1.2.3
