So far I have been using normal avering to calculate the normals for my vertices in my heightmap, with good graphical result (see picture), however it is terribly slow. With a incresing image size the ...
My Task I want to interpolate a heightmap by using the normal of each nearby point of the heightmap which is calculated before. When having 4 Points before i gonna have 9 points after it. ( See this ...
I have some height-map sampled on a regular grid stored in an array. Now, I want to use the normals on the sampled vertices for some smoothing algorithm. The way I'm currently doing it is as follows: ...
