Hi there, I'd like to procedurally generate a height map in run time and don't want to save it to the image, as it costs in additional overhead. I'm looking for a way to use 2d array instead of image url (the array dimension may serve as a number of subdivisions). Obviously I don't want to rewrite the CreateGroundFromHeightMap function, because this function is works fine and there is no need at all to reinvent a wheel. What I'd expect for, is that CreateGroundFromHeightMap will consist of two functions - the basic one, which receives the two dimensional array, and the wrapper function which converts the image to the 2d array. I'm wondering how can I do it without changing the code of the framework (maybe I'm missing something), and why its's not done this way so far? P.s. If you will look at the implementation of CreateGroundFromHeightMap, you will notice that this is what actually happening there - first of all get the data from the image, and then build the height map. It's just not organized well (or, again, maybe I'm missing something).
