Creating on the fly objects and projecting them on texture

[farshizzo]

Hi,

When you create an On-The-Fly object for the screen, the vertex positions need to be in screen coordinates. Screen coordinates range from 0 to 1. (0,0) is the bottom left corner of the screen and (1,1) is the top right corner. So in your case you don't need to bother with the viz.screentoworld function since the points are already in screen coordinates.
