Recently, I had the need to turn a hundred different texture images into "profiles." A profile, in this case, was a 2D shape that follows the outline of some feature in the texture (like a house facade), texture mapped with that feature. Rather than build them all in a modeler such as 3ds Max, and separately exporting them, I came up with a simple tool for loading a bunch of images, building those profiles straight on a copy of the image using clicking, saving all the profiles I've built (for later re-use or editing), and exporting to a bunch of .DAE (collada) or .X files in one fell swoop.
1) WORLD matrix. This takes vertices from object-local space (0,0,0 in the middle of the object) to world space (position and orientation applied based on 0,0,0 at your "world origin" position). This is a convenient space to do normal mapped lighting and environmental reflection in.
Attached, please find a syntax highlighting file for HLSL and Effect files for Notepad++. This file is substantially better than the one available on the Notepad++ main download site:
The Simple Audio Plugin Specification
Preview release 2009-01-14

This book/forum intends to describe the development of the Simple Audio Plugin Specification (SAPS for short), which serves two purposes:
It seems to me as if PIX for Windows, and its integration with the NVIDIA device drivers, has just gone downhill during the last year or so. I have a single project, which can demonstrate bugs both in the latest NVIDIA graphics drivers, and in the PIX tool itself.
The ODE physics library (http://www.ode.org/) has been around for a long time. Often, people ask "how do I do a good arcade car" or "how do I do a good character simulation" using ODE.
I've been hacking on XNA again. This time, I built a car simulation out of rays and a tire friction model. I'm using JigLibX for collision detection and force integration, but I'm not using the built-in car simulation, as it didn't get me the response I needed.
Geometry rasterization is about transforming vertices, which in the end make up the corners of triangles, which get rendered on the screen (very simply put).
