Remove Border Triangles

How To Remove Badly Shaped Border Triangles A Delaunay triangulation is convex but that does not always hold for your data. As a consequence your triangulation may contain triangles close to the convex hull that do not really belong to the desired non-convex result. This post shows how to remove them. Minimal Example in C++ […]

Random Polygons, Surfaces, Segments for Automated Software Tests

Geometry programming: Degenerate cases, numeric issues and unexpected geometric settings make a developer’s life hard. Automated software stress tests with random data are essential to discover bugs early. But creating random polygons without self-intersections or even random surfaces is for example not trivial. For convenient debugging the module testDataGenerators can be used to create repeatable […]

Runtime for a Face List

Storing a triangulation as a list consisting of three indices per triangle is a common task and leads to a frequently asked question that reads as follows: “Creating a triangulation with Fade is fast. But when I store a face list of vertex indices it runs forever. What is wrong?”. The basic answer: It is […]

Progress Bar Mechanism

Fade is very fast and most of the time you won’t need a progress bar. But for huge operations you may want to connect your progress bar to Fade’s progress update mechanism. Step 1: Create your own class Create some custom class that derives from MsgBase so that it can receive messages from Fade. The […]
