Intermact API Reference / @intermact/render-three / ThreeObject3DView

Class: ThreeObject3DView

Defined in: object-view-3d.ts:53

Renders one 3D Intermact object (design.md §15.2, §10) into three.js objects and updates them from a RuntimeState3D diff: transform (position + quaternion + scale), opacity, and Create reveal. The provider's GeometryProvider3D.kind selects line / mesh / points.

• Lines reveal by arc length (honoring revealStart/revealEnd), using each segment's cumulative length so motion is uniform regardless of sample density.
• Geometry is hot-rebuilt when geometryVersion bumps (reactive recompute / replaceObject), mirroring the 2D view.
• Point clouds with per-point scalars are colored via a rampColor ramp.

Framework-free: R3F hosts group and calls update per frame.
