Hello,
Houdini beginner here, I am looking for a solution to project geometry from a given single point (labelled as the green dot in the diagram, just above the mid point of the sphere) to y=0 to make a semisphere.
The point is to have a flat ground without deformations and changes to the UV projection while a camera is positioned at the given point. So say you had a panoramamic image/video applied to the semisphere, it would look undistorted when viewing from this given point.
Thanks in advance!
