Leriel appears to be a floating sphere with a distorted black and white color pattern that suddenly appears in the sky above the three wards of Tokyo. However, Leliel’s entity is actually a shadow that appears on the ground. Leliel’s body in our dimension is 680 meters wide and 3 nanometers thick, and the sphere is merely its “shadow.
basic policy
- We have a beautiful material image, so we use this as the original data and generate it programmatically.
- Find a point in two dimensions when it is projected from the viewpoint and the coordinates to place it.
- Obtaining color from a material image
- Placement of blocks with [mcpi
python

vp = np.array([6009.50, 80.00 + 1.5, 2.50])

cam_y = tp - vp
cam_y = cam_y / np.linalg.norm(cam_y)
cam_x = np.cross(cam_y, np.array([0, 1, 0]))
cam_x = cam_x / np.linalg.norm(cam_x)
cam_z = np.cross(cam_x, cam_y)
image = skimage.io.imread(f'/Users/nishio/Documents/leliel.png')

I’m projecting a 2D image onto a sphere in the micro-world.
It’s so cunning.
The world is covered in darkness.
I know how long it takes to rewrite.
- I thought about making a video shoot of the rewrite of the gun because it was interesting, but when I checked the original, it was more like it moved slowly and then suddenly came to the sky, rather than rewrite.
