Search tables with colors in VTK

The method for searching a table is

1. Read the scalar or to the most, and store it with a vtkfloatarray. The scalar in it can represent different colors.

2. Create a search table, use setnuberofcolors () to allocate space, assign values, and use build () to create a search table.

3. Combine the scalar array with the vtkfloatarray and the polygon, and combine the lookup table with the vtkmapper.

 

Note: The float type is used for table search.
