Can anyone point me in the direction of some easy to use programs for creation of floating point textures (free programs)? I'd also like a place where I can find the file format definitions (such as which bit should be what in the headers etc.) for any floating point image file format(s) that are widely spread and popular. Also I'd like to hear if there are any file formats that the OpenGL and DirectX APIs support, for example if the DirectX method CreateTextureFromFile() can handle the formats. Finally I'd like to hear some general opinions on which formats you think are the best floating point formats for game textures, height maps and other uses, and which ones you think will become the most widely spread formats in the nearest future.
