I want to calculate the surface area of an irregular object, the object has been grided and now I know the coordination of grids right on the boundary, the next step is that I have to try to use surface triangulation to creat traingles on boundary, then calculate the surface area(or other better ways you can think?).
but I do not know how to write C code for this transformation, anyone can help me? reply here or email <adameye at gmail>? thanks

To find the surface area of any object:
create a function which tells you whether any point is inside the object's boundaries.
then test a grid of points that are in a square around the object. Each point should be a certain distance away from the other points in a grid. thus you are pixellating the object. If a point is in the object, then add the area of a square the size of the grid squares to the total area.
