HLSL issue/artifact ?

Hello all,
I am using a vertex shader in my demo, and to my surprise, when my model is far away from the camera, the back faces appear in the front.
It is a little bit as if the code that calculates what to display (I use vertex skinning, with HL... |

Tool associating physics to 3D models ?

Hi there,
I was wondering if existed somehow a *generic* tool that would let one associate physics models to 3D models ? What I mean by that is that such a tool would enable one to load a 3D model (MS3D for instance) of his/her choice,... |

2D openGL engine - flickering & performance

Hello raigan,
Thank you for the tip but it is the first thing that I checked :-)

Java disadvantages

I am surprised not to read anything about the *supposedly* Java multi-platform feature. I remember back in the years, where my Java program would behave differently depending on the JVM. Sometimes it would simply crash.
