UVtoSPACE

[temiroff]

Hello anybody knows about how convert UV space to World space of my object ?

Need a little more information.

Are you in a material shader when you do this?

Do you mean that you have arbitrary UVs for a particular texture space, and that you want to look up where that UV maps to an object, and then get the world space location for that point?

Or do you mean something more like a tangent space defined along the uv directions of a particular texture space?

What are you trying to do in general? For example, maybe we need to use different terminology and approach it a different way.

i'm sorry for a long absent i have geometry shader and i need for example ask where is it my world's point of my object for my U 0.5 V 0.5

HELP?

Now, I'm confused. Did your geometry shader not assign the uvs to each vertex itself?

Where are you getting the data from? This might be easier done in a 3D application which has more of this kind of modeling information.

I think I know, what you want to do with this. What kind of information do you have? If you know on which triangle has these UV coordinates, than you can easily calculate the world coordinates of this UV point (assuming you don't have overlapping areas in the UV map).

If you don't know it, you can go through all of the vertices, and find yourself what triangle has these points.
