Billboard calculation wrong in Matrix class #740

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi! 
It seems that the Billboard algorithm mixes up two vectors.
The Billboard matrix for following parameters should be Identity:
Obj Position      = (0,0,0)
Cam Position      = (0,0,-30)
Cam UpVector      = (0,1,0)
Cam ForwardVector = (0,0,1)

...but it is not! The first and second row are interchanged.
So the first row must be the Final vector and the second row the Crossed vector.

Cheers
Karol
