I need a greyscale heightmap of the world to be used as a basic for my terrain program. For the purpose of this project, the desired end result is a PSD or BMP file with a worldmap. The greyscale values should be between 0 and 240 for the bottom of the see to the highest mountains. It is possible to use a heightmap of the real world as starting point. However, due to the scale of the worl in my terrain renderer, a real hightmap does not provide sufficient height differences but looks rather flat. for this reason, it is necessary to alter a real heightmap either in photoshop or tools like terragen or others I might not even know about. I tried terragen but it seems to unstable for this task. I care only about the resulting picture. It is also possible to apply severla filters like Perlian Noise which is commonly used in terrain generation in photoshop with the appropriate plugins, again I have no deeper knowledge about what is available here. I can provide a sample greymap of the world as a starting point, but there is no obligation to use it. I will also provide a sample program of my terrain engine. The generated heightmap can simply be put into the application directory as a jpg and the terrain can be seen in the renderengine. This should make communication easier. The program runs only on graphiccards which support Shader 3.0, for example NVIDIA 62000 and up or the respective Radeon cards. The desired result is a heightmap that provides sufficient terrain detail in my render engine. I believe that in order to do so, nearly every pixel must be slightly differnt from the neighbors. The picture should be 2000 * 2000 pixel and the waterline should be around greylevel 70. This is another problem, since the worldmap I have does probably not provide a waterline at that greylevel. A profound knowledge of photoshop or a similar high end program is essential for this task I believe.
1) a BMP or PSD file with the final worldmap, suitable to be rendered in my renderengine which provides sufficient height differences to make the resulting terrain look versatile and interesting in general. 2) All deliverables will be considered "work made for hire" under U.S. Copyright law.
