◆ getInstanceBuffer()

QByteArray QQuick3DParticleInstanceTable::getInstanceBuffer ( int * instanceCount )

Implement this function to return the contents of the instance table.

The number of instances should be returned in instanceCount. The subclass is responsible for caching the result if necessary. If the instance table changes, the subclass should call markDirty().

Implements QQuick3DInstancing.
