Difficult time understanding generating terrain (from file)
I downloaded this program terragen and have generated random terrains and saved them as raw image data. I understand that each byte of the raw data file corresponds to a height ranging from 0-255 and those are my vertex coordinates for thet triangles/trianglestrip. The thing I have a difficult time understanding is do I plot the triangles in rows of two starting with the first point on the first row, then the first on the second row, then second on the second row etc? Or do I plot them each row at a time (first one on first row, then second, then third, etc)?
