Geometry Cubes

Example showing multiple rotating cubes. This also tests the depth buffer.

import imageio.v3 as iio
import pygfx as gfx
import pylinalg as la


group = gfx.Group()

im = iio.imread("imageio:chelsea.png")
tex = gfx.Texture(im, dim=2)

material = gfx.MeshBasicMaterial(map=tex)
geometry = gfx.box_geometry(100, 100, 100)
cubes = [gfx.Mesh(geometry, material) for i in range(8)]
for i, cube in enumerate(cubes):
    cube.local.position = (350 - i * 100, 0, 0)
    group.add(cube)


def animate():
    for i, cube in enumerate(cubes):
        rot = la.quat_from_euler((0.01 * i, 0.02 * i), order="XY")
        cube.local.rotation = la.quat_mul(rot, cube.local.rotation)


if __name__ == "__main__":
    disp = gfx.Display()
    disp.before_render = animate
    disp.show(group)
