i need to be able to move a marker along the surface of a mesh without using the mouse.
With the mouse it was kind of easy, just using the scene.pick() method.
Now with the numeric / keyboard control this is a tad more difficult.
What I’d like to achieve is that the user can use two keys or numeric inputs to control the position in the 2D space which then gets translated to the meshes 3D space.
I have found this thread:
But I am not sure if there might be a different, simpler option which escapes me now.
