I3dmPayload

Decoded i3dm payload: a shared glTF mesh + a flat list of per-instance transforms. Renderer emits one instanced draw call (or instancesLength non-instanced draws on platforms without glDrawElementsInstanced).

Properties

gltf

val gltf: GltfModel

instancesLength

val instancesLength: Int

positions

val positions: FloatArray

Per-instance translation, flattened (x0, y0, z0, x1, y1, z1, ...). Always present.

rtcCenter

val rtcCenter: DoubleArray?

RTC_CENTER (instance position offset). Null when absent.

scales

val scales: FloatArray?

Per-instance scale, flattened (sx0, sy0, sz0, ...). null when the asset uses uniform scale-1 (the renderer treats null as identity to save an attribute upload).
