Modifier and Type	Method	Description
static float[]	convertToFloat(short... shorts)	Convert a short array to a float array
static float[]	pad(float[] src, int srcElementSize, int attribSize)	Expand out our src data so that each attribute is a certain size, padding with 0's as needed.
static short[]	pad(short[] src, int srcElementSize, int attribSize)	Expand out our src data so that each attribute is a certain size, padding with 0's as needed.
static float[]	reorderAndPad(float[] src, int srcElementSize, int matSide)	Rearrange the data from data per element, to a list of matSide x matSide matrices, output by row as such: row0element0, row0element1, row0element2... row1element0, row1element1, row1element2... row2element0, row2element1, row2element2... If there is not enough values in the source data to fill out a row, 0 is used.

Method Details

setAutoUpdateBounds

public static void setAutoUpdateBounds(Spatial root,
 boolean doUpdate)

Simple utility to turn on / off bounding volume updating on skinned mesh objects in a given scenegraph.

Parameters:

root - the root node on the scenegraph

doUpdate - if true, skinned mesh objects will automatically update their model bounds when applying pose.

convertToFloat

public static float[] convertToFloat(short... shorts)

Convert a short array to a float array

Parameters:

shorts - the short values

Returns:

our new float array

reorderAndPad

public static float[] reorderAndPad(float[] src,
 int srcElementSize,
 int matSide)

Rearrange the data from data per element, to a list of matSide x matSide matrices, output by row as such: row0element0, row0element1, row0element2...
row1element0, row1element1, row1element2...
row2element0, row2element1, row2element2...
If there is not enough values in the source data to fill out a row, 0 is used.

Parameters:

src - our source data, stored as element0, element1, etc.

srcElementSize - the number of values per element in our source data

matSide - the size of the matrix edge... eg. 4 would mean a 4x4 matrix.

Returns:

our new data array.

pad

public static float[] pad(float[] src,
 int srcElementSize,
 int attribSize)

Expand out our src data so that each attribute is a certain size, padding with 0's as needed. If src is already correct size, we just return that without creating a new data array.

Parameters:

src - our source data, stored as element0, element1, etc.

srcElementSize - the number of values per element in our source data

attribSize - the desired size of each element in the return array.

Returns:

the padded array.

pad

public static short[] pad(short[] src,
 int srcElementSize,
 int attribSize)

Expand out our src data so that each attribute is a certain size, padding with 0's as needed. If src is already correct size, we just return that without creating a new data array.

Parameters:

src - our source data, stored as element0, element1, etc.

srcElementSize - the number of values per element in our source data

attribSize - the desired size of each element in the return array.

Returns:

the padded array.
