rotation problem

Quote:

Original post by badescuga I wish to rotate a model around it's center(ex. rotate a planet around it's axis) but all that i can find regarding rotation is the Matrix.CreateFromYawPitchRoll which rotates the model around the position Vector3.

CreateFromYawPitchRoll() doesn't rotate around an arbitrary position. But, the math library you're using should include a function for building a matrix from an axis-angle pair, which may be what you're wanting.

That said, by combining transforms appropriately, you can in fact use CreateFromYawPitchRoll() to effect a local-axis rotation, so if you're wanting to rotate the planet about one of its local basis vectors, you can still use this function.

okei, thanks. i'll start looking around for the apropriate function
