qapm_tri_editor: Tool to create/edit triangles

The qapm_tri_editor tool enables creating and editing triangulations of sets of points.

Creating a triangulation

Run the tool and load in a set of points (and optionally an image)
If you wish, this can be done from the command line: qapm_tri_editor -i image1.png -p image1.pts The tool can then

Create a triangulation (using "Delaunay")
Delete triangles
Edit the mesh by "swapping" triangles
Create new triangles by clicking on three points in turn


1) Initial set of points	2) After applying Delaunay

3) Deleting triangles outside region of interest	4) Swapping triangles to edit the mesh

If a triangulation file exists, it can be loaded, for instance using qapm_tri_editor -i image1.png -p image1.pts -t triangles.tri

Modes

Delete: Click near centre of triangle to delete
Swap: Click on arc between two touching triangles to swap them; (1,2,3),(1,2,4) becomes (3,4,1),(3,4,2).
Add: Click on three nodes in sequence to create a triangle between them.
