Matrix transform basics

Transforms are objects that embody generic position and orientation data. Vizard uses them internally for all its operations. You can use these to:

create complex motions not possible with standard methods
operate directly on 4x4 homogenous matrices
utilize many handy matrix math functions available

Creating Transforms

mat = viz.Matrix() # Create a fresh matrix object
mat.postTrans([0,1.8,0]) # Post multiply it by a translation matrix

Applying to 3D objects

mat = viz.Matrix()
mat.setPosition([0, 1.8, 0])
myObject = viz.add('beachball.osgb')
myObject.setMatrix(mat)
