Class

SurfaceSupportSampler3D

Generated GDScript class reference for GridPlacement.SurfaceSupportSampler3D.

Status: Draft
Version: v6.0
Updated: Development docs generated from GDScript source

This is unreleased documentation in active development. APIs, class names, and behavior may change before the final release.

Physics-backed 3D support sampler. Casts deterministic downward rays across a GRID footprint. The returned evidence is consumed by [SurfaceSupportEvaluator3D]; this class owns no placement policy.

Members

Name	Kind	Summary
`SAMPLES_PER_CELL`	Field	Four quadrant samples per footprint cell.
`RAY_ORIGIN_ABOVE`	Field	Start far enough above ordinary terrain relief to avoid originating below it.

`ROLE_CENTER`	Field
`supported`	Property	One downward support ray: where it landed (or the intended X/Z on a miss), the surface normal (zero on a miss), and its role: a footprint coverage sample or the explicit footprint-center probe.
