geo/SDFSolidAngle
Creates an SDF spherical cone.
Sdf Primitives
Creates a solid angle as SDF geometry: a cone opening along +Y from its center, closed by a piece of sphere rather than by a flat or rounded cap. At 180 degrees it is a hemisphere, and past that it is a sphere with a cone bitten out of the bottom. 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.
Parameters
| Name | Type | What it does |
|---|---|---|
| t | Vector3 | Center: the cone's apex, and the center of the sphere that closes it. |
| radius | Float | Radius of the sphere the shape is cut from. |
| angle | Float | Full opening of the cone, in degrees, measured across the axis: 180 gives a hemisphere. It stops short of a full turn, where the shape would be a whole sphere and the field would break down along the axis. Use geo/SDFSphere for that. |
