Sources editing software landscape based on the height map (OpenGL + Delphi). Shimma program can be downloaded from the author's website: http://alexeyspace.ru/programs/5/.
Height map is a graphic file with the extension * .bmp. It can be edited directly in the program, or download the file. Recommended dimensions of uploaded images 250 250 pixels. The image must be saved in grayscale. Height map is in the bottom right corner of the program. To edit it there are three kinds of brushes, you can also change the pressing force of the brush, and its size. The brighter the color of any area on the map, the higher will be the appropriate scientific fields on the landscape. Ie the brightness of a point on the map determines its height above the surface. The first two brushes can brighten areas of the map, ie, create hills. Third - dimming, ie smooth hills.
On the built landscape superimposed textures, with the lighting. You can choose from several two textures that will be imposed on the land and the mountains.
The program also displays the skybox - an object in three-dimensional graphics, playing the role of the sky and horizon. You can choose three options skybox - day, evening and night.
Well, the most interesting feature of the program is that you can then stroll through the creation of the landscape! By pressing the F9 key on the keyboard, or press the corresponding button on the toolbar. We switch to a first person view. And you can control the movement of the landscape, the mouse and the keys W, A, S, D, and perform jumps "space".
