Unfortunately not, there's no concept of 3D in VB at all without developing

it yourself or using an external 3D library such as DirectX. If you want to

have a go at it yourself then hit Google and search for 3D mathematics

principles, alternatively if you want to use DirectX then you'll need a mesh

for the vector object (With the foot of the mesh centred on (0,0,0)) then

position and rotate it using a transformation matrix based on your vector.

Hope this helps,

Mike
