Hi,

The DBpro Help on WORLD MATRIX4 said,
"This command will copy the world matrix into the specified matrix."

What does this mean anyway? As far as I know, world matrix are the transformation matrix (position, rotation, and scale) of an object in the world. This command does not take any object as parameter, so what does it return anyway?

How about VIEW MATRIX4 and PROJECTION MATRIX4 commands? My assumption is these command will refer to the transformation matrix of the current ACTIVE camera. Is that right?

Thanks in advance!

I think that's the sound of people not really knowing the answer ...

I *guess* that the 'world matrix' could be the transformation matrix for the current camera position. Following on from that, I'd also guess that the 'view matrix' and the 'projection matrix' also use the current camera ...

All of them could be for the default camera instead though.

Was that enough guessing for you?
