Now I am confused. Here’s a breakdown of what I’m trying to do - bear in mind that I’m pretty new to OpenGL so this is a bit of a minefield for me.
I have a collection of points that have been extracted from Ordinance survey data and are stored in a text file, like so:
Anyway from thes points I wish to generate a height map of the area. Thats all I want to do. The reason I had asked about interpolation is because I had read that a simple way of generate a height map was to use a grid and simply read in z values, but that could be wrong, like I said I’m new to this. I’m not entirely sure what you meen about mesh either. Sorry - my apologies if I’m stating the obvious. Hope this helps you to see what I’m tryin to do.
Cheers for your help
