LowMemoryVertexBufferObject

Class Overview

Compared to a HighPerformanceVertexBufferObject, the LowMemoryVertexBufferObject uses 50% less heap memory, at the cost of significantly slower data buffering (up to 5x slower!). Usually a LowMemoryVertexBufferObject is preferred to a HighPerformanceVertexBufferObject when the following conditions are met:

1. The applications is close to run out of memory.
2. You have very big HighPerformanceVertexBufferObject or an extreme number of small HighPerformanceVertexBufferObjects, where a 50% heap memory reduction would actually be significant.
3. The content (color, vertices, texturecoordinates) of the LowMemoryVertexBufferObject is changed not often, or even better: never.
