Places clones at per-point transforms a GPU compute pass writes into a buffer — the way to drive a cloner from positions computed on the GPU each frame (a physics step, a flocking simulation, a compute-shader layout).
Declarative element:
<sk-compute-buffer-points-source>
Not on the sk.* global — construct via the declarative element or a module import.
This is a data-driven member of the points-source family (see
ShaderFunctionPointsSource): a points-source defines the set of
positions at which a sk-cloner places copies of its content, so it lives
as a child of a <sk-cloner> and the cloner's other child is the template
cloned at each point. Unlike the procedural sources — which generate their
points from a formula — this one takes its placements from a
sk-compute-node: the cloner binds the producer's GPU buffer slice
directly (zero-copy, nothing read back to the CPU), so the layout can be
regenerated on the GPU every frame at no transfer cost.
Key attributes. compute-node references (by #id) the
sk-compute-node whose output supplies the placements; that node must be
declared with output-kind="point-matrices" so it emits PointData records
(one local matrix per point). compute-property-key selects which output to
read when a node exposes several — it defaults to output.0, so a single-output
producer needs no key. The source stays inert (zero points) until the referenced
producer is resolved and GPU-ready.
Related. For placements written as a per-index function instead of a compute
pass, see sk-custom-wgsl-points-source; both pair naturally with a
sk-compute-node. For object/data-driven placements see
sk-mesh-vertex-points-source, sk-mesh-surface-points-source,
sk-buffer-points-source, and sk-cloner-points-source; for
built-in procedural shapes see sk-grid-points-source and
sk-sphere-points-source. Its host is always a sk-cloner.
