My first attempts at 3D took place on a Casio 7000G, it was a simple rotating cube then a bouncing ball. On the following calculator, I was able to distort the image of the rotating cube according to polar coordinates and having “lens distortion”… Then my math teacher came and asked me what I was doing. I was 15 and already on the autism spectrum. I really started 3D with Cinema 4D, then discovered Blender 2.49. I love procedural things: materials and geometry nodes of course.
