[SOLVED] Is there anything in three to simplify projecting a 3d point on a plane and getting the 2d equivilant

[user123]

I have a plane, this plane could be in any orientation/angle, I know the planes normal and centre. I also have several points (3D) that are on that plane.

I am looking for a way to transpose my 3D points and get the equivlant 2D points on that plane?

I found the following link, which seems logical…

Projecting 3D points to 2D plane

I often go about things in one way before finding out theres a neater solution using some of threes methods so i thought id ask if anyone suggest a neater way?

Hi!
Have a look at this forum thread:

2D object in 3D space (by Vertices)

Hi everyone! I have a problem: How to draw 2D, flat object given by Vertices in 3D Space? I have an array with 3D Points, and I want to draw line from Points[0] to Points[1], from Points[1] to Points[2] etc… Now I have a following solution: var geometry = new THREE.BufferGeometry(); var vertices = faceToTriangles( VerticesArray ); // my function var uvs = new Float32Array([ 0.0, 0.0, 1.0, 0.0, 1.0, 1.0, 0.0, 0.0, 1.0, 1.0, 0.0, 1.0 ]); geometry.addAttribute( 'position', new THR…
