Have a look here http://www.acm.org/tog/GraphicsGems/gems/MatrixPost.c it's
not quite what you want but it might help.

Subject: [Algorithms] Creating the world matrix



Hi!

I'm looking for a fast way to create the world matrix from the values of 
pitch, yaw, roll and position(and scaling factor, perhaps), without using a 
matrix operation for each value.
I would like to avoid do the folowing

WorldMatrix = MatrixIdentity();

MatrixScale(WorldMatrix, scale);

MatrixTranslate(WorldMatrix, position);

MatrixRotateX(WorldMatrix, pitch);
MatrixRotateY(WorldMatrix, yaw);
MatrixRotateZ(WorldMatrix, roll);

SetWorldMatrix(WorldMatrix);


Yes, I know the code is not efficient, and perhaps wrong, but its only a 
example.

I'm using D3D Immediate Mode.

Any ideas?


Thanks in advance.

Aldo
