Add example: Getting UV projected texture image

[Karric]

Please add example code of how I can get the mesh's UV texture with the projected image applied to it.

Please also consider the scenario where the mesh is not unwrapped and thus has no base texture.

not sure what you mean by "get the mesh's UV texture", can you elaborate what you're trying to do?

[marcofugaro]

What you're talking about is texture baking, it is possible in three.js, but you'd have to do it by hand.
There is not example in three.js, but you might find some resources in the issue: mrdoob/three.js#14055.

Not related to this library, you could bake any three.js material.

@marcofugaro ok, understood. I'm having a second issue. It seems like ProjectedMaterial requires lights in the scene. Is there some way to render this material as shadeless? I tried passing flatShading: THREE.FlatShading when I create the material, but this did not do anything. I added an ambient light, but it lightens the projected texture too much. I checked online and could not find very much about shadeless.

Hi Marco, as Karric says, don't you think it could be possible to uv unwrap the texture once projected to the mesh ? so let's say a second shader that reads the current pixels projected on the mesh and fit the uvmaps that the object already has. So let's say an scenario where you load an obj file with uv maps (created in blender or any other software) and then projecting the pixels form the initial texture projection to the final uv maps projection ?
Thanks in advance

Here I prepared an illustration to show visually what could be achieved directly via shader

Yes it's possible, that's what texture baking does. But you have to do it yourself because it's out of scope of this library.
