public class SoCpuBufferBitSet extends SoCpuBufferObject
LDM buffer object optimized for bitset tile data. This type of buffer efficiently represents a tile containing bitset data. The buffer can be used like any other buffer, but uses less memory when its contents are not actually being accessed.SoBufferPropertiesInterface

Method Detail

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)
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).
-
getRealSize
public long getRealSize()
Returns the size of the buffer in bytes.
For this type of buffer the real size is the same as the size of theSoBufferObject
.
-
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.
-
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.
-
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
-
setMinMax
public void setMinMax(double min, double max)
Set min and max values for this buffer.- Parameters:
min
- user variable containing min valuemax
- user variable containing max value
-
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.
