interview in Spanish with #Chaitin
#video demonstrating how to visualize #raycasting in #Godot #toread
terrain #mapgen for mountain #graphics with fractal Perlin noise and iq’s “gradient trick”, where you attenuate higher-frequency layers wherever the gradient of the lower-frequency layers is large; also, with diffusion-limited aggregation with a gradually increasing level of detail, and with “dual-filter blurring” #image-processing, where you alternate downsampling an image with blurring it, then alternate upsampling the result with blurring it, much like multiscale low-pass filtering with Hogenauer filters. Very nice pure-CGI #video.
#raytracing #graphics including #algorithms like resampled importance sampling, reservoir sampling, temporal reuse, spatial reuse, and #ReSTIR. Another very nice pure-CGI #video
#Fraser makes a more powerful blow-tube lamp for glassworking #bootstrapping #video #toread
“giving personality to procedural animations (for #games) using math” illustrated using Manim. Reparameterizes a second-order ODE with natural frequency f, damping coefficient ζ, and response speed r, to get a conveniently controllable system, then integrates it with the semi-implicit Euler method, then analyzes the eigenvalues of the state transition matrix to ensure stability. #video #graphics
#styropyro 100 car batteries in parallel, reaching 50 kiloamps #video mostly melting a bunch of metal things very rapidly
#video on writing 50 video #games in 10 years, mostly in PyGame. Some pretty interesting visuals with particle systems and whatnot.
