In picture mode: - Use the left and right arrows to select a butterfly. - Press space to draw the butterfly in 3D. In 3D drawing mode: - Use left and right arrows to flap the wings. - Press B to change the backdrop and C to change the pen color. - Press R to select a new butterfly to draw.
This is a variation of my 3D Object Drawing Machine: https://scratch.mit.edu/projects/129497471/ Like that one, this project scans the object image before rendering it. The scanning algorithm is a bit more complex, capturing internal details of the wing, not just the outer contours.
