I’m trying to create camera projection with geo-nodes to store image color on point cloud color attribute, but I’m not into trigonometry at all.
What I’d like to achieve is this:
But with geo-nodes - not on a shading level.

$\begingroup$ Is rephrasing your objective as what follows is correct ? (1) You have an image, imported as an object (a plane ?). (2) You have a point cloud. (3) You have a camera set to look at the image (1) through the point cloud (2). (4) You would like to colour a point according the background pixel seen in line "behind" it. $\endgroup$– StefLAncienCommented May 9 at 12:54

1$\begingroup$ Could you provide your Blender file using blend-exchange.com with image and point cloud ? $\endgroup$– StefLAncienCommented May 9 at 12:55

Seems I did it with new 4.2 matricies nodes combining setup I had in shading.
Inside geo-nodes there are 3 drivers - to get camera angle and shift x/y for proper mapping. So to use in defferent scene - be sure to remap those drivers to scene camera.
