Utility class used to safely access channels of a buffer.
Utility class used to safely access channels of a buffer. The bufferObject is mapped in the constructor and unmapped in the destructor.

SbImageDataVoxel::SbImageDataVoxel | ( | const SbImageDataType & | channelType, |
SoBufferObject * | buffer, | ||
size_t | offset | ||
) |
channelType | Type of channel (number of channel + data type) |
buffer | main buffer containing data. Use to keep data alive and ensure they wont be deleted elsewhere. |
offset | offset in byte to beginning of channel inside buffer. |
SbImageDataVoxel::~SbImageDataVoxel | ( | ) |
Unmap buffer.
SbImageDataVoxel::SbImageDataVoxel | ( | const SbImageDataVoxel & | ) |
Copy constructor.
TypeOut SbImageDataVoxel::castValue | ( | size_t | channelIndex | ) | const |
Return value casted to the proper type.
Return a copy and not a reference because data may be int and you may want to cast to float. Throw exception if channelIndex >= getImageDataType().getNumChannel().

Return channel type.

TypeOut & SbImageDataVoxel::getValue | ( | size_t | channelIndex | ) |
Return reference to values.
Throw exception if wrong type is specified. Throw exception if channelIndex >= getImageDataType().getNumChannel().
