Interpolation in vtk
VTK Related Presentation for Scientific Visualization (CS 526)
The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing, and visualization used by thousands of researchers and developers around the world.
Computer Visualization involves discrete data that is either provided or sampled at discrete points. We may need information at positions other than these discrete points for rendering or for sub-sampling the data during algorithm execution. This is where Interpolation Functions comes into the picture. My Presentation was about Interpolation in vtk. Here is the ppt.
