No, Pygame is a wrapper for SDL, which is a 2D api. Pygame doesn’t provide any 3D capability and probably never will. 3D libraries for Python include Panda3D and DirectPython, although they are probably quite complex to use, especially the latter.
Instead of cylinder to sphere mapping I would do a sphere triangulation… I would first start with 2 hexagons each start at pole and end on the equator or do the half only and mirror the other when all done… then recursively subdivide the triangles so divide lines to half and change the mid point … Read more
For ray picking rendered objects (like by mouse) the best option is to use the already rendered buffers as there is very little cost of reading them in comparison to ray intersection tests on complex scene. The idea is to render each pick-able rendered object to separate buffer per each info you need about them … Read more
It is a little complicated, but you can draw all the objects by the following code: from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt import numpy as np from itertools import product, combinations fig = plt.figure() ax = fig.gca(projection=’3d’) ax.set_aspect(“equal”) # draw cube r = [-1, 1] for s, e in combinations(np.array(list(product(r, r, r))), 2): … Read more
So the question really is Understanding 4×4 homogenous transform matrices well without the math behind the only thing that left is geometric representation/meaning which is far better for human abstraction/understanding. So what the 4×4 matrix is? It is representation of some Cartesian coordinate system and it is composed of: 3 basis vectors (one for each … Read more
