Oh boy I love questions like this! Obviously check out the GOAT Inigo Quilez's page for basic SDF rendering techniques: https://iquilezles.org/articles/ This helped me get my SDF rendering a bit more stable: [video Mike Turitzin has a beautiful SDF engine he's building: [video Here are some other helpful resources I found on specific SDF rendering techniques: Skipping Spheres algorithm: https://diglib.eg.org/server/api/core/bitstreams/0dd5043c-6ac0-4b83-b3d2-d0b1ad34afba/content#3#1 Area lights using cone tracing: https://diglib.eg.org/server/api/core/bitstreams/08a7b5a8-876f-48ab-ab9a-456e94b15fe4/content#1#1 CTSS (Cone-traced super sampling, an anti-aliasing technique for SDFs s…
