I need to create a terrain that can be used in C++ and opengl and I am told that using a height map is the way to go. I have a .bmp file that is a greyscale image that I would like to use. However, I do not know how to load that greyscale image into the project so that it can be used as a height map or how I can apply a texture to it to create terrain nor how to compute the normals that I'm told will be required. How would I go about achieving what I would like to do?
