instances

Placing copies of a source on points, varying them, and realizing, drawing or spawning the result.

The definitions live in proc.ops.instances; this pack is what puts them in the op registry, so procgen.searchNodes("", { pack = "instances" }) lists the family and procgen.describeNode("op.<id>") describes any one of them.

Ops

• instances.on_points — Stand a source on every point: a geometry or mesh is carried by each point as its Mesh (and its material as its Material), placed by P, orient and scale — a Generator draws the points as one instanced draw placed on...
• instances.randomize_transform — Per-instance random yaw/tilt/scale Field<Transform> for a point cloud
• instances.pick_random — Stand one of several sources on each point, dealt by a seeded, weighted draw: each point's Mesh is its index into the sources, which the points' detail lists
• instances.pick_by_attribute — Stand one of several sources on each point, picked by an integer point attribute: each point's Mesh is its index into the sources, which the points' detail lists
• instances.realize — Copy the source standing on every point into one merged Geometry
• instances.spawn — Spawn one addressable entity per point of a population (live, per-instance transform)
• instances.draw — Draw a population as one hardware-instanced draw per source variant, each with its own source material
• instances.set_material — Dress every point of a population with one material: its Material, read when the points are drawn, realized or spawned
• instances.transform — Rigidly transform a population: move/rotate the layout and rotate/scale each instance
• instances.from_bundle — Spawn a .bundle prefab at every point (positioned by the per-instance transform)
