Terra Editor
The DreamScape Terra Editor window is a floating dialog where you define height fields for your landscapes to use to displace their surface.
At the top of the window are a number of menus for importing data, special effects and viewing the height field you are working with.
Beneath those are a series of button icons that provide quick access to your paint and selection tools.
The large preview window (currently all black) is where you can paint elevations and slope angles interactively, as well as apply special effects to the height field map via the menus at the top of the dialog.
Finally, along the right side of the dialog are a series of command panels where you can define specific properties for your height field painting efforts as well as create procedural erosion to your height field.
There are also a number of Keyboard Shortcuts you can use to navigate the Preview window described below.
