Geometry Instancing

Render one piece of geometry many times with per-instance transforms, colors, and textures via geometryCOMP instancing.

Data Sources

instanceop accepts any operator family — pick based on data characteristics:

• tableDAT — static/hand-authored. Set instancefirstrow=names
• CHOP — animated/procedural (LFO, noise, soptoCHOP). Most common
• TOP — texture-driven, large instance counts
• POP — directly (preferred) — point a transform source OP at a nullPOP and reference point attributes with P(0)/P(1)/P(2) (position), attrib_name(i), etc. No poptoCHOP round-trip, no GPU→CPU cost. e.g. instancetop=null_positions, instancetx=P(0), instancety=P(1), instancetz=P(2)
• POP via poptoCHOP — only when you need the data as CHOP channels for other ops. GPU→CPU cost

Split sources: instancetop (translate), instancerop (rotate), instancesop (scale). instanceop is the default fallback. Each accepts a POP directly — use P(n)/attrib syntax in the channel selectors.
