Simple Perspective Correction

Beginners
1

Hi,
Forgive me but I can’t remember if this is something simple or difficult to do (or if I have to use camSchnappr or something).

Basically I just want to project a flat image onto a sphere (or other shape) and make it look correct from a certain perspective.

Just using the image → Material → Geo’s color map distorts the image.

In this example I used a texture SOP inside the geometry and tried to change it to “perspective from camera” (with a camera looking at a grid), unfortunately the 3D geometry still distorts the image.

I would appreciate any pointers on how to make a simple perspective warp. Thanks

Do you mean simple polar uv on a sphere ?
or some kind special projection on sphere to make the viewer to think he watch flat surface ?

added simple polar UV

Thanks Barakooda,
I was referring to your last point. I would like to make the viewers think they are looking at a flat surface on the complex geometry.

Ideally I would like to figure a way to make this work on not just spheres but other complex geometry as well.

Are there any solutions of this type?

Use the “perspective from camera” option in the texture sop to set texture coords according to the audience pov.
