Sharing a fun visualization of how bins are rendered. Intentionally slowed down simulation, and the actual hardware itself has a lot of known optimizations to implement. Green Square: GPU Clearing Tile Red Square: GPU Drawing Triangle Blue Square: GPU Storing Tile to Framebuffer

@john_goetz @Dry417 @GameRant Not to mention the realtime Global Illumination. The light from the sun illuminates through the atmosphere in realtime. Causing realistic lighting situations like these. Impossible with baked lighting. Notice also the gas giant yellow bouncing onto the moon surface?

Working on a video now - the differences are staggering. Hopefully a big game like this can finally showcase the benefits of Lumen (and Nanite, of course) to the masses! Light actually behaves like light.

My favorite, simple rotation trick: angle = time - sin(time); This makes it smoothly start and stop every 2pi radians. You can also rotate quarter turns like so angle = time - sin(time*4.)/4.; Demo code: o+=length(max(abs((FC.xy-r*.5)*rotate2D(t-sin(t*4.)/4.))-.3*r.y,0.));

an explanation of refraction. When a wave changes its speed and wavelength at a boundary, it must change its direction so that the amplitudes match up at the boundary
