From 06bce2ddd0958cff3c2ee477a880e998dfc48be7 Mon Sep 17 00:00:00 2001 From: "Graham Linden graham@lindenlab.com" Date: Thu, 15 Feb 2018 21:55:24 +0000 Subject: Add debug setting and code to allow nVidia nSight graphics debugging to capture SL frames. These changes are only enabled if RenderNsightDebugSupport is true and eliminate use of some OpenGL legacy functionality which is incompatible with nSight capture (mostly glReadPixels and other fixed-function pipe rendering calls). --- indra/llrender/llgl.cpp | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'indra/llrender/llgl.cpp') diff --git a/indra/llrender/llgl.cpp b/indra/llrender/llgl.cpp index 155c2402bd..35b6951779 100644 --- a/indra/llrender/llgl.cpp +++ b/indra/llrender/llgl.cpp @@ -1348,8 +1348,19 @@ void LLGLManager::initExtensions() if (mHasVertexShader) { LL_INFOS() << "initExtensions() VertexShader-related procs..." << LL_ENDL; + + // nSight doesn't support use of ARB funcs that have been normalized in the API + if (!LLRender::sNsightDebugSupport) + { glGetAttribLocationARB = (PFNGLGETATTRIBLOCATIONARBPROC) GLH_EXT_GET_PROC_ADDRESS("glGetAttribLocationARB"); glBindAttribLocationARB = (PFNGLBINDATTRIBLOCATIONARBPROC) GLH_EXT_GET_PROC_ADDRESS("glBindAttribLocationARB"); + } + else + { + glGetAttribLocationARB = (PFNGLGETATTRIBLOCATIONARBPROC)GLH_EXT_GET_PROC_ADDRESS("glGetAttribLocation"); + glBindAttribLocationARB = (PFNGLBINDATTRIBLOCATIONARBPROC)GLH_EXT_GET_PROC_ADDRESS("glBindAttribLocation"); + } + glGetActiveAttribARB = (PFNGLGETACTIVEATTRIBARBPROC) GLH_EXT_GET_PROC_ADDRESS("glGetActiveAttribARB"); glVertexAttrib1dARB = (PFNGLVERTEXATTRIB1DARBPROC) GLH_EXT_GET_PROC_ADDRESS("glVertexAttrib1dARB"); glVertexAttrib1dvARB = (PFNGLVERTEXATTRIB1DVARBPROC) GLH_EXT_GET_PROC_ADDRESS("glVertexAttrib1dvARB"); -- cgit v1.2.3
