vtkVoxelModeller is a filter that converts an arbitrary data set to a structured point (i.e., voxel) representation. It is very similar to vtkImplicitModeller, except that it doesn't record distance; instead it records occupancy. By default it supports a compact output of 0/1 VTK_BIT. Other vtk scalar types can be specified. The Foreground and Background values of the output can also be specified. NOTE: Not all vtk filters/readers/writers support the VTK_BIT scalar type. You may want to use VTK_CHAR as an alternative.
To create an instance of class vtkVoxelModeller, simply invoke its constructor as follows
obj = vtkVoxelModeller
The class vtkVoxelModeller has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, obj
is an instance of the vtkVoxelModeller class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkVoxelModeller = obj.NewInstance ()
vtkVoxelModeller = obj.SafeDownCast (vtkObject o)
double = obj.ComputeModelBounds (double origin[3], double ar[3])
- Compute the ModelBounds based on the input geometry. obj.SetSampleDimensions (int i, int j, int k)
- Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50) obj.SetSampleDimensions (int dim[3])
- Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50) int = obj. GetSampleDimensions ()
- Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50) obj.SetMaximumDistance (double )
- Specify distance away from surface of input geometry to sample. Smaller values make large increases in performance. Default is 1.0. double = obj.GetMaximumDistanceMinValue ()
