Constructor Detail

DynamicGeometry

public DynamicGeometry(float[] data,
                       BufferObject arrayBuffer)

Creates a new dynamic geometry that will draw from a VBO.

Parameters:

data - the array from which vertex data will be copied at each update.

arrayBuffer - the VBO into which the vertex data will be copied.

DynamicGeometry

public DynamicGeometry(float[] data,
                       FloatBuffer floatArray)

Creates a new dynamic geometry that will draw directly from a float buffer.

Parameters:

data - the array from which vertex data will be copied at each update.

floatArray - the buffer into which vertex data will be copied.
