I’ve got two points in 3d space, and I want to draw a box between them that acts like a line. If I can translate to get to the first point, how would I find the rotation values that could make my box aligned so that one of the edges of the box connects from the first point to the second point?

I haven’t tested but perhaps lookAt in this article is what you need [image] 3D Rotations in Processing (Vectors, Matrices, Quaternions) This tutorial introduces how to rotate objects in 3D beyond Euler angles; to do this, it looks at the basics of matrices and quaternions… Reading tim…

simplified of my link above // Demo program for a 3D line final color RED = color(255, 0, 0); final color GREEN = color(0, 255, 0); final color BLUE = color(0, 0, 255); final float a = 200; PVector point0 = new PVector ( -a, -a, -3*a); // point 0 PVector point1 = new PVector ( 133, 10,…

Hello, I did this a few different ways: Trigonometry to get the angles and then do 2 rotations. Convert the Cartesian co-ordinate to spherical co-ordinates and do 2 rotations. It is a worthwhile exercise to do this from scratch from the formulas provided. Use PVectors to get the angleBetween() a…

How do I find the rotateX,rotateY, and rotateZ values to make any vector vertical?
