From a2a3d8d7f056a9c3c613da62ddc2618bf5227ce6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 6 Aug 2009 13:55:09 -0700 Subject: [PATCH] intel: Fix googleearth by avoiding GL_VIEWPORT_BIT in meta clear push/pop I have no idea why this fixes things, but being more efficient sounds good anyway. Fixes regression in 99d07d0f91ddd37926d08f4e7f10d55cac28d9a7 where most of the lit half of the world was not drawn. --- src/mesa/drivers/dri/common/dri_metaops.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/mesa/drivers/dri/common/dri_metaops.c b/src/mesa/drivers/dri/common/dri_metaops.c index fe183c2e870..cdbea344951 100644 --- a/src/mesa/drivers/dri/common/dri_metaops.c +++ b/src/mesa/drivers/dri/common/dri_metaops.c @@ -357,6 +357,7 @@ meta_clear_tris(struct dri_metaops *meta, GLbitfield mask) GLuint saved_shader_program = 0; unsigned int saved_active_texture; struct gl_array_object *arraySave = NULL; + GLfloat saved_near, saved_far; if (!meta->clear.arrayObj) meta_init_clear(meta); @@ -370,8 +371,7 @@ meta_clear_tris(struct dri_metaops *meta, GLbitfield mask) GL_POLYGON_BIT | GL_STENCIL_BUFFER_BIT | GL_TRANSFORM_BIT | - GL_CURRENT_BIT | - GL_VIEWPORT_BIT); + GL_CURRENT_BIT); saved_active_texture = ctx->Texture.CurrentUnit; /* Disable existing GL state we don't want to apply to a clear. */ @@ -440,6 +440,8 @@ meta_clear_tris(struct dri_metaops *meta, GLbitfield mask) /* The ClearDepth value is unaffected by DepthRange, so do a default * mapping. */ + saved_near = ctx->Viewport.Near; + saved_far = ctx->Viewport.Far; _mesa_DepthRange(0.0, 1.0); /* Prepare the vertices, which are the same regardless of which buffer we're @@ -519,6 +521,7 @@ meta_clear_tris(struct dri_metaops *meta, GLbitfield mask) if (saved_shader_program) _mesa_UseProgramObjectARB(saved_shader_program); + _mesa_DepthRange(saved_near, saved_far); _mesa_PopAttrib(); /* restore current array object */ -- 2.30.2
