java.lang.Object

icyllis.arc3d.granite.geom.BoundsManager

icyllis.arc3d.granite.geom.HybridBoundsManager

public final class HybridBoundsManager
extends BoundsManager

A BoundsManager that first relies on FullBoundsManager for N draw calls, and then switches to the GridBoundsManager if it exceeds its limit. For low N, the brute force approach is surprisingly efficient, has the highest accuracy, and very low memory overhead. Once the draw call count is large enough, the grid's lower performance complexity outweigh its memory cost and reduced accuracy.
