1. The Hole Filler Helper By Russell Palmiter

2. Holes Where do they come from? –Geometry acquisition and simplification Why fill them? –Many graphics algorithms depend on manifoldness –Visually displeasing Goals in filling them –Filled automatically –Filled without significant delay –Accurate to original topology Or at least visually pleasing

3. Algorithm 1.Start With: Unstructured Mesh 2.Find Holes 3.Triangulate the Hole 4.Refine Triangulation

4. Algorithm 1.Start With: Unstructured Mesh 2.Find Holes 3.Triangulate the Hole 4.Refine Triangulation = Kalman Filter

5. Kalman Filter Prediction Correction

6. The Prediction-Correction-Cycle Correction Prediction

7. Where are Kalman Filters Used? Control Theory Avionics Stochastic Modeling Economic and financial modeling Digital Signal Processing Head Tracking Applied Optimal Estimation

8. And Now… It’s used in the process of filling holes in unstructured meshes
