| | Project a texture over the terrain, scaled to the model The projection is isometric down the Z axis so maps nicely to terrain that is nearly an XY plane.

|
| virtual void | colorizeByElevation (osg::Node *node, const std::string &definition, int textureunit=0) |
| | Colorize a terrain using a specified gradient When scale and offset are 0.0, the gradient is stretched to match the terrain such that 0 in terrain-local coordinates represents the midpoint of the gradient.

Recursively exempt anything under node that should not be texturized.
This should be done once before using any of the automatic texturing functions (drapeTexture, colorizeByElevation, etc.) and will prevent texturing on detectable non-terrain elements. Calling this more than once is harmless, but it can be time-consuming for large terrain.
