Nice! What would be cool is try to render crazy amount of pipe with fixed view by not clearing render targets each frame. This way on CPU side you only need to store 3D bit array and next segment data. I think this way you can render absolutely bonkers amount of pipes!

this man is a genius

this guy lays pipes

I've always wondered how this screensaver was implemented. I wonder if you could have made it way simpler by using a depth buffer and just successively drawing a sphere without clearing the screen.

Can you explain further?

@@zokalyx Sure. The idea is that to draw a "tube" you're using a lot of spheres. Instead of drawing a lot of sphere every frame, you just draw a single sphere moving very slightly, without clearing the screen in between and without clearing the depth buffer(But with depth tests enabled while drawing!). The sphere should now be tracing a path, and the look of this path should be the "extrusion" of that sphere( a cylinder). Should work with other shapes as well. Kind of like how when you're clipped out of the skybox in e.g. half-life objects leave a trail.

@@Maxjoker98 Thanks! That does sound smart. I now understand the concept of using spheres. About the depth buffer thing... is that so you don't draw on top of another pipe if it's closer to the screen?

@@zokalyx Yes exactly. Depthbuffers store the "depth" (distance from camera) per-pixel, and then you only update a new pixel if it is closer to the camera than the old one. Otherwise, the "pipe texture" would just be the border of the sphere, instead of defined by the shape, and behind/infront would be wrong. I also think maybe there is a 2D-only version of this effect.

Cool bro
