Terrain Terraform Editor... The Terrain Terraform Editor is used to algorithmically generate terrain heightfields. Heightfield operations are arranged in a stack, with some operations using the results of previous operations to produce new heightfields. The results of the last operation on the stack can be applied to the terrain using the Apply button. The Terraform Editor has two panes - the top pane displays information about the currently selected operation, and the bottom pane shows the current operation stack. Between the two is a pull down menu for the creation of new operations. The first operation in the stack is always the General operation (which can't be deleted). The following operations are supported in the editor: fBm Fractal - Fractal for creating bumpy hills Rigid Multifractal - Fractal for creating ridges and sweeping valleys Canyon Fractal - Fractal for creating vertical canyon ridges Sinus - Overlapping sine wave patterns with different frequencies useful for creating rolling hills Bitmap - Used to import an existing 256x256 bitmap as a heightfield Turbulence - perturbs another operation on the stack Smoothing - smooths another operation on the stack Smooth Water - smooths water Smooth Ridges/valleys - smooths an existing operation on edge boundaries Filter - filters an existing operation based on a curve Thermal Erosion - erodes an existing operation using a thermal erosion algorithm Hydraulic Erosion - erodes an existing operation using a hydraulic erosion algorithm Blend - blends two existing operations acording to a scale factor and mathmatical operator Terrain File - loads an existing terrain file onto the stack
