Detailed Description

Array position - dense buffer index (0, 1, 2, ...)

Array positions are sequential indices into GPU buffers. They are computed during geometry building by reordering primitives by parent object for cache locality.

Allows implicit conversion to size_t for convenient array indexing.

ArrayPosition pos{5};
float value = buffer[pos];  // Implicit conversion to size_t
