Hi all,

For a project I’m doing I need to translate a texture coordinate to a coordinate in 3D space. So far I have not been able to find any clues on how to achieve this and I’m stuck with this problem.
Is there a method available that I can use, or should I hook some code in to achieve this?
Any help in pointing me in the right direction is highly appreciated!

Thanks,

Paul

There is a class doing this practically out of the box: barycentricTest in tools. The only thing required, is to interpolate the values of the uv coordinates from the “bounds” that you define from the 3 face vertices and their respective uv’s.

Thanks for your quick reply Fabrice and sorry for my late reply back to you.

It looks like this class that you are referring to does the opposite for what was needed, as this will return a UV coordinate based on a face’s position in space. What I was looking for is to get from a coordinate in a texture to a 3D position in space.

Fortunately my 3D object is quite simple, as I’m working with a sphere. This allows me to transform a texture coordinate myself with some math.

The MouseEvent3d returns you the uv coordinates and the position in space.
