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.SoBufferPropertiesInterface

Method Detail
-
map
public void map(SoGLBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode)
Calls map(targetBufferObject, accessMode, (long)0, (long)SO_BUFFER_SIZE_ALL).
-
map
public void map(SoCpuBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode, long startPosition)
Calls map(targetBufferObject, accessMode, startPosition, (long)SO_BUFFER_SIZE_ALL).
-
map
public void map(SoCpuBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode)
Calls map(targetBufferObject, accessMode, (long)0, (long)SO_BUFFER_SIZE_ALL).
-
map
public void map(SoGLBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode, long startPosition)
Calls map(targetBufferObject, accessMode, startPosition, (long)SO_BUFFER_SIZE_ALL).
-
map
public void map(SoGLBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode, long startPosition, long mappingSize)
Map the current buffer object into the specified GL buffer object.
See the general map method for more information.
-
map
public void map(SoCpuBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode, long startPosition, long mappingSize)
Map the current buffer object into the specified CPU buffer object.
See the general map method for more information.
-
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.
-
getRealSize
public long getRealSize()
Returns the real size of the buffer in bytes.
-
getType
public SbDataType getType()
Get the type of the value of the uniform tile.
-
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 valuemax
- user variable to store max value
-
unmap
public void unmap(SoCpuBufferObject bufferObject)
Unmap the specified CPU buffer object
It is defined just to speed up the call when the type of the object is known.
Remove the specified bufferObject from the list of buffers which map the current buffer.See the general unmap function for more information.
-
unmap
public void unmap(SoGLBufferObject bufferObject)
Unmap the specified GL buffer object
It is defined just to speed up the call when the type of the object is known.
If the access mode supports writing the specified buffer is sync'd with the buffer.See the general unmap function for more information.
- Parameters:
bufferObject
- Buffer to be unmapped.
-
setValue
public void setValue(double value, SbDataType dataType)
Set the value and data type for this uniform buffer.
