Constructor Detail

MrBuffer

public MrBuffer(int capacity,
                MrDataType dataType,
                int target,
                int usage)

Creates a new buffer

Parameters:

capacity - capacity of this buffer, required to memory initialization

dataType - Type of data will be stored, usually short or float

target - Target type for VBO or IBO

usage - Usage of this buffer, usually it will not change, so STATIC_DRAW is used
