I’m working on a CPU voxel raytracer in Python. With the amount of costly calculations involved everything must be as efficient as possible especially storing and fetching point data in space. I started by storing 2D and 3D data in dictionaries indexed by string positions, eg: data["4,16"] == "solid". Since converting positions to and from… Read More Convert list index to a 3D position based on width and height
I decided to learn a bit about matrices and 3D cameras and made some educational project for myself, to understand how it works. Swift and SwiftUI because I’m a bit familiar with. But question is more math-general-oriented. Why x-rotation looks wired? y-axis and z-axis looks great btw. Here are my matrices for rotation and camera:… Read More X-rotation looks wired
I have a multidimensional array (P x N x M) and I want to plot each N x M array in a 3D plot in such a way the P images are stacked along the z-axis. Do you know hw to do this in Python? Thanks in advance >Solution : If you want N x… Read More How to plot a multidimensional array in a 3D plot?
My ploted circle with n-generated points looks completely fine in 2D: Generated circle in 2D (x,y) However when i tried to plot the circle with half of the points increasing z value and half of them decreasing z value it looks like this: xyz circle xz view I want to make it tilted to the… Read More 3D rotated circle in matplotlib
