Hi

Do someone know how to do this in vb nx journal

'I found this solution in the internet and I need it in vb nx journal

'This is done by multiplying the point with the WorldViewProjection matrix... i.e.
'WorldViewProjection Matrix = World Matrix * View Matrix * Projection Matrix
'2D Point = 3D Point * WorldViewProjectionMatrix

Thanks in advanced

RE: (World View Projection Matrix) Do someone know how to do this in vb nx journal

Projecting a point using matrix multiplication is just standard linear algebra. The text you quoted looks like it comes from an OpenGL document. That same document probably tells you how to do matrix multiplication.

None of this has any relationship to NX.

If you want a better answer, you'll probably have to clarify the question.
