Camera : fisheye 180

Hello,

I’m actually trying to have a Fisheye camera without using the RENDER TOP’s fisheye option !
So I know there is a “projection matrix/CHOP/DAT” option or “custom projection GLSL DAT” option too but I don’t know how to use it and how to get the same effect that the RENDER TOP.

My goal is to get an UV mesh distortion as a fisheye for my 3D model.

Thanks :wink:

Have you looked at the Projection TOP?

hello Ben,

I think I might found what I was looking for : this is the texture SOP with an “Equirectangular Inside (Spherical Polar)” option in the texture Type.

But this doesn’t give me the same result as a 3D software like C4D for exemple.
In the 3D software I need to move the spherical UV mapping higher on Y axis like 1m70 (human size). In Touchdesigner I’m still looking how to know where is the reference of the spherical polar origin of my texture SOP.

Is there a way to see the texture SOP’s origin in the Geometry viewer?
