• devalapa_k Rotation about the z-axis...

  I have a square on screen (2 triangles), and I'm experimenting with rotating the thing.

As for how I'm doing it right now, I'm using Matrix.RotationYawPitchRoll(x, y, z) to get my rotation matrix. ...Show All

• Paz 9000 Degraded performance when debugging MDX1.1 applications in VS2005 compared to VS2003

  Hello, I've noticed that when I'm debugging MDX1.1 applications in VS2005, they achieve a significantly lower framerate than when debugging them in VS2003. The performance decrease differs per application and seems to be somehow linked to the use of HLSL effects, as applications that use the Fixed Function Pipeline do not suffer this decrease. This morning I witnessed an extreme case of this problem with a little game that renders mul ...Show All
