right now my idea is to figure out a way to create a way to create forest scenes for a project I'm working on, and use sort of a method of pre-rendering the scene, and then applying it in a way which would allow for at a certain altitude/distance and below, the trees and such would be 3d, however further out that would be done with 2d billboards, similar to the trees in MS FSX or X-Plane 9. The areas would be pre-generated by defining in a layout tool certain regions in which to make a mass of trees, or putting individual trees/shrubs in manually, and then saving it into a landscape that's usable. The general idea is to create a method of simulating forests for ground operations at a higher detail, or for jets, a lower detail the further up you get. I would try to use a layout tool using something like google earth for reference imagery, to try to decide where to put these chunks, and individual areas, and put down the objects. Then I might work on a ground texture method whi ch would allow for higher detail ground textures the closer you get. The layout tool is still a work in progress, or at least version 2 is, so that's up in the air. The overall idea though is to create a functional foliage system for the project which would allow for high details on the ground, while maintaining good frame rates in the air. The databases would all be based off placing it in a editor based off satellite imagery, and using polygons to define some areas where it's just a big massive forest for example. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16362#16362 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
