Hi everyone,
I want to project an object from a point (like a spotligth with shadow and parametable angle) and get this projection on a plane (like a texture).
Do you think it’s possible?
Code :

Yes like a spotligth (that I know). But let it only produce black and white on plane material. And second point, that I can get the texture generated on the plane (with a camera?)
I think the best solution is to go through a shader that pass a position (the origin of the cone) and the projection angle. But I don’t know how to do that in three.js 
Hi!
There are several topics about projection

I don’t want to project a texture but the meshes from a point on surface (and get this).
A wild shot: maybe this topic will be helpful Camera + EllipseCurve
I make a version that works with a spot light. But I would have preferred a purely shader solution. Thank you for your answers;) !
