Hi Ariel
I have a lot of points (topographical survey points) and these points are defined by X, Y and Z coordinates. These points then get triangulated with the help of Agraham's Delauney dll
Now, when I tap with my stylus inside any triangle, the program will return the X and Y position where I tapped on the screen. The program then uses these X and Y values to find out in which triangle I have tapped.
Now comes the difficult part. Using the X, Y and Z coordinates of the triangle in which I have tapped, the program needs to calculate a "Z" (height) value of the point where I have tapped, using the values of the 3 corners of the triangle.
Like I have said previously, it works with least squares adjustment, but only to a certain point.
Hope you can help
Thanks
Michael
