public class SoCpuBufferUniform
extends SoCpuBufferObject

LDM buffer object optimized for uniform (single value) tile data. This type of buffer efficiently represents a uniform tile, in other words a tile in which every value is the same. The buffer can be used like any other buffer, but uses very little memory when its contents are not actually being accessed.

public SoCpuBufferUniform(double value,
                          SbDataType valueType)

Constructor.

Parameters:

value - Initial value of uniform buffer.

valueType - Initial value type of uniform buffer.

SoCpuBufferUniform

public SoCpuBufferUniform()

Default constructor.

Method Detail

setValue

public void setValue(double value,
                     SbDataType dataType)

Set the value and data type for this uniform buffer.

getValue

public double getValue()

Get the value of the uniform tile.

setRealSize

public void setRealSize(long realSize)

Set the real size of the buffer object in bytes.

getType

public SbDataType getType()

Get the type of the value of the uniform tile.

getRealSize

public long getRealSize()

Returns the real size of the buffer in bytes.

getMinMax

public double[] getMinMax()

Get the min and max values in the buffer, if they are known.
Returns false if these values have not been set or computed. Returns true if values are available.

Parameters:

min - user variable to store min value

max - user variable to store max value
