geo/SDFEllipsoid
Creates an SDF ellipsoid.
Sdf Primitives
Creates an ellipsoid as SDF geometry: a sphere with a separate radius per axis. The field is an approximation of the true distance, exact on the surface and slightly short away from it, which is what keeps a sphere trace from overstepping. Wire it to the geo/Output node to see it raymarched, or compose it with other SDF objects through geo/SDFBoolean, geo/SDFRepeat and geo/Transform. Dragging the params never recompiles the preview shader. For fields beyond the wrapper primitives, use geo/SDFBuilder and the code/SDF* library.
Parameters
