Commodore C64 demo Mathematica by Reflex. Captured from a real C64 using s-video cable and audio from a 8580 SID chip. Some postprocessing done with the interlaced effects to get around RU-vid framerate issues.
@@patsfan4life They're talking about 1:24. It looks like spheres in 3D, but actually it are just circles of different sizes that are drawn on top of each other. Z ordering is what specifies which circle should be on the foreground and which should be on the background.
@Dark0Lord7 Works the same as a mandelbrot set, except you change the initial condition before iterating. changing the condition without panning results in the various julia sets being shown.
most of this is just smoke and mirror, half animation half realtime stuff :) fex. a realtime raycaster is 3-4x slower. on c64 and a realtime phong torus is 20x :)
I don t think their phong like torus is animated or video. - kindof quarter resolved and fuzzy upsampled but the shortcuts work to create a fast scene. Similar less restricted rendering happens at a lower framerate in "Oxyron - ReLIGHTening" for comparison.
@@adymode its very simple, the torus' rotation is an animation, and its 2d rotation (around the axis thats orthogonal to the screen) is done by polar mappign the torus animation. or if you want the torus is sliced up into "angles", and by picking which angle is mapped (shown) onto which angle on screen it gets rotated, another benefit of this "angle" approach that the animation can be mirrored, as you see the torus is symmetrical always on the screen to 180 degree. you can do this by a few assembly instructions, as the resolution is small, so every pixel has these few instructions assigned and the polar offsets for the lookps are precalculated. the cube is the same, just a few phases of "true" rotation animated. I code c64 demos since 30 years, I have done much more complex effects, this is a simple thing in my book.
