The following options apply to all projects.

• Fill Mode - defines how layers are rendered. Possible values are:
  • Solid (default) -  Layers are rendered as a solid surface.
  • Wire frame - Only the outline of layers is rendered.
• Backgrounds - Here you can set the background colors of the 3D surface, and the mini-map.

Ramps

You can create a library of predefined color ramps, which you can use later to quickly create desired layer symbology.

Color ramps consist of at least two colors. You can add up to 50 colors in a color ramp. ET Terrain Viewer will automatically create a gradient between the distinct colors of the ramp if the number of classes of the symbology is greater than the number of distinct colors in the ramp.

Point Markers

You can create a library of point markers, which you can use later for multi-point layers.

Point markers can be created from:

1. Images - click button Add Image to select an image file. The image must be no larger than 128 x 128 pixels. It is recommended that you use images in format PNG with defined transparency to achieve best effect.
2. Symbols - you can add symbols from installed fonts on your computer. ET Terrain Viewer provides a font named ETTV2, which contains a number of symbols. Click button Add Symbol, then select the desired font, select the color for the symbol, and type in the desired symbol, or select one from the drop-down list. ET Terrain Viewer will convert the symbol into a transparent image, and add it to the library.
