Lithosphere is a GPU driven terrain generator. It allows you to create and export material textures and heightmaps intended for use in realtime graphics applications.All terrain algorithms are implemented as GLSL fragment shaders operating on floating point textures. This allows realtime modification of the terrain. A graph of nodes is evaluated in order to arrive at the terrain output.Features Realtime terrain modification Save/Open of scene.lth files Simplex noise height source Wind and Erosion algorithms Gaussian Filtering Mixing and Adjusting Mathemathical operators Float array and DXF mesh export PNG texture exportRequirementsLithosphere requires a fast computer and graphics card to operate. It also requires specific opengl compatibility OpenGL shading language version 1.20 GL_ARB_texture_float GL_ARB_pixel_buffer_object GL_ARB_vertex_buffer_object GL_ARB_framebuffer_objectRecommended system specs Intel Quad Core CPU 2gb RAM Nvidia Geforce GTX-285 1gb video ramWorking with Nvidia Geforce GTX-285 Nvidia Geforce 8800 GTS Nvidia Quadro FX1700 512mbNot working with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (no floating point textures) Mac OSX Leopard (comes with python2.5, you can install python2.6) Geforce 7700 (too slow) Multiple grapics cards in use on the system (non SLI, tri-monitor setups etc., OpenGL context sharing does not work in such setups)LicenseLithosphere is licenced as AGPL version 3.0 or above.WhoLithosphere is written by Florian BÃ¶sch (facebook, linkedin)StandaloneThe standalone distribution contains all dependencies but no python, you will need 32bit python2.6 installed on your system. It has been tested with windows and linux, no test on snow leopard so far, it might run. Execute the file "run.py" contained in the distribution to run the application.Version 0.1.2 - Mon Mar 29 2010 Lithosphere 0.1.2 Alpha tgz Lithosphere 0.1.2 Alpha zipWhat's new in 0.1.2 Ambient occlusion strength saved in scene file fixed the simplex noise shader to be glsl 1.20 compatibleSee the full changelogExamplesThese are examples that are also contained in the source. examples.tgz examples.zipLinuxA Linux debian installer package is in the works.WindowsA windows executable and installer is in the works.Mac OSXI have no suitable apple machine that would run lithosphere, help appreciatedViewport NavigationIn order to use the 3d viewport, you have to click into it to focus. It gets an orange border when it is focused. Mouse drag for look key for flying left and key [F] for flying right key [E] for flying forward and key [D] for flying backwards key [W] for flying up and key [R] for flying down key [Right Shift] for slowing movement speed to 1/10thSlidersThe sliders you find in lithosphere can be very sensitive. If you want to slow down the rate of change of a slider, you can hold [Right Shift] while you modify it. Sliders can be modified in these three ways: Drag them with the mouse If a slider is focused (glows orange) use the mouse scroll wheel to change it If a slider is focused use the cursor keys (/) to change itToolbarThe toolbar allows you to save/open scene files and create nodes from which you create your terrain.NodesNodes appear in the work area (bottom of the screen) when you create them. The nodes may have inputs, which are on the left side of the node widget. Nodes have output, which is on the bottom right side of the node Widget. Outputs can connect to many Inputs, but one Input can only connect to one Output.There are three kinds of nodes. Source nodes have no input, they are what you start with. Operator nodes combine multiple inputs to one output. Filter nodes modify primarily one input, and optionally a weightmap that determines the weight of the effect.
