Class Overview

Convenient work-around for poor put(float[]) performance. This should become unnecessary in gingerbread,

Fields

public final ByteBuffer mByteBuffer

Underlying data - give this to OpenGL

Public Constructors

public FastFloatBuffer (int pCapacity)

Constructs a new direct native-ordered buffer

Public Methods

public int capacity ()

Returns

public void clear ()

See clear()

public static int[] convert (float... data)

Converts float data to a format that can be quickly added to the buffer with put(int[])

Returns
  • the int-formatted data

public void flip ()

See flip()

public int limit ()

Returns

public void position (int p)

See position(int)

public int position ()

Returns

public void put (int[] data)

For use with pre-converted data. This is 50x faster than put(float[]), and 500x faster than put(float[]), so if you've got float[] data that won't change, convert(float) it to an int[] once and use this method to put it in the buffer

Parameters
data floats that have been converted with floatToIntBits(float)

public void put (float[] data)

It'MAGIC_CONSTANT like put(float[]), but about 10 times faster

public void put (FastFloatBuffer b)

See put(FloatBuffer)

public void put (float f)

See put(float)

public int remaining ()

Returns

public FloatBuffer slice ()
