Orthographic unproject

[gaia]

What are the steps required to unproject (2D->3D)? I’ve tried vec3Object.unproject(camera) and the results are not correct. I’m trying to select a 2D rectangular region (screen coordinates) and get that rectangular region in 3D (world coordinates). I need to get the vertices that exist in the rectangular region.

Have you tried it like demonstrated here:

How to unproject mouse2D with Orthographic Camera

Try this: const vector = new THREE.Vector3(); vector.set( mouse.x, mouse.y, ( camera.near + camera.far ) / ( camera.near - camera.far ) ); vector.unproject( camera ); BTW: You do not project. You unproject^^.
