A hash code should be immutable and deterministic so is unlikely to be based on memory address?

In Topic: Polygonizing a grid after subtracting an irregular portion

14 February 2013 - 12:26 PM

Here I only know the grid points And the boundary points to be subtracted. Boundary points may not fall within the grid points. Then with which coordintes I need to construct the delaunay triangulation? Could you explain?

Well, you could triangulate the boundary, do an intersection test of all the grid points against the triangles, remove those which intersect then retriangulate with all remaining points?

Wouldn't be particularly efficient but should work I guess...


If using python, Shapely is a nice library for stuff like this.

In Topic: Polygonizing a grid after subtracting an irregular portion

I have a regular grid. I need to subtract some irregular part from it as shown in the figure. I know the coordinates of the portion to be subtracted. How can I polygonize the rest of the grid after subtracting that irregular portion? There may be a number of ways. Could any one give me some suggestions?


Construct a Delaunay triangulation from the vertices?

Flash is free for commercial use, the Adobe toolchain is not. Free development alternatives exist. iOS will not run the Flash web plugin. You can build an Air executable and put it in the app store. You have to pay Apple for this, as a regular app.
