AVX in Visual Studio 8 8 (4/19/2013 5:55:16 PM) comp.lang.c++ Hello I've just started to convert some c++ code which is optimised for sse4 to avx. After a few false starts with Visual Studio, I've finally started to generate avx code. Unfortunately the result is... Thomas

Shader profiling 4 36 (2/22/2012 8:06:25 PM) comp.graphics.api.opengl Hello I managed to put together a half-decent deferred shader and it's significantly faster than my original one-stage shader. Now I'm in the process of optimising the shader and I wondered if there were any... Thomas

Multisampling Vs Supersampling 7 93 (2/13/2012 12:17:14 AM) comp.graphics.api.opengl Hello I'm struggling to understand the essential difference between multisampling and supersampling but I'm getting the impression that multisampling makes more compromises in order to maintain frame-rates. ... Thomas

Writing to the Stencil Buffer 9 34 (2/8/2012 7:46:36 PM) comp.graphics.api.opengl Hello I want to write to the stencil buffer at the face level in order to avoid having my deferred shader operate on fragments which don't apply to a particular face. I was intending to use the GL_ARB_shader... Thomas

fragment position 1 50 (2/7/2012 3:31:47 PM) comp.graphics.api.opengl Hello If I have the depth of a fragment (from the depth buffer) and the fragment coordinates, can I determine the model space coordinates of the surface underneath the fragment and if so how? Thanks for any... Thomas

Trying to understand framebuffers and multisampled render targets 3 53 (2/6/2012 11:40:46 AM) comp.graphics.api.opengl Hi Further to my recent post, I'm struggling to understand how multisampling works with framebuffers. I'm ok with floating point formats but I can't seem to make things work with unsigned bytes. I set up a ... Thomas

Easy ways to speed up rendering? 13 47 (1/27/2012 7:48:03 PM) comp.graphics.api.opengl Hi I have a custom fragment shader which needs to do a fair bit of work per fragment including multiple texture look-ups and a lot of math. Not surprisingly, the shader runs quite slowly on models with more ... Thomas

Accessing local uvw coordinates in fragment shader 5 29 (4/5/2011 3:06:35 PM) comp.graphics.api.opengl Hello Does anyone know if it's possible to access the interpolated uvw coordinates within a fragment shader? I know that the 'varying' keyword lets you access the interpolated value of any particular vertex ... Thomas

What does SET_PLOT, 'x' mean ? 4 33 (6/12/2009 12:38:26 AM) comp.lang.idl-pvwave Hi all, I am working on an old IDL code right now. And several parts of the code do not work well. I am nor sure whether it is because of the version or because of the poor coding. (But this is a published cod... litongmu.ustc (9)
