helper class for a ray cast image
This is a helper class for storing the ray cast image including the underlying data and the size of the image. This class is not intended to be used directly - just as an internal class in the vtkFixedPointVolumeRayCastMapper so that multiple mappers can share the same image. This class also stored the ZBuffer (if necessary due to intermixed geometry). Perhaps this class could be generalized in the future to be used for other ray cast methods other than the fixed point method.

As long as the memory size is big enough, but not too big, we won't bother deleting and re-allocated, we'll just continue to use the memory size we have. This size will always be equal to or less than the ImageMemorySize.

Set / Get the origin of the image.
This is the starting pixel within the whole viewport that our Image starts on. That is, we could be generating just a subregion of the whole viewport due to the fact that our volume occupies only a portion of the viewport. The Image pixels will start from this location.

The UseZBuffer flag indicates whether the ZBuffer is in use.
The ZBuffer is captured and used when IntermixIntersectingGeometry is on in the mapper, and when there are props that have been rendered before the current volume.

float vtkFixedPointRayCastImage::GetZBufferValue | ( | int | x, |
int | y | ||
) |
Get the ZBuffer value corresponding to location (x,y) where (x,y) are indexing into the ImageInUse image.
This must be converted to the zbuffer image coordinates. Nearest neighbor value is returned. If UseZBuffer is off, then 1.0 is always returned.
|
inline |
Get the ZBuffer.
The size of the ZBuffer should be specific with SetZBufferSize, and AllocateZBuffer method should be called before getting the ZBuffer.
