This layer type loads an image and renders it over the complete 3D-window. The image dimension is not used. You have to adjust the ratio of the 3D-window manually to avoid distortions. The transparency can be adjusted to blend between the image and the scene.
Like the previous "Add Image"-function, this layer type loads an image and can adjust its transparency. In addition it adjusts the ratio of the 3D-window and reads EXIF-values from the image. The focal length is used to adjust the camera of the 3d scene. To position the camera, the lat- and lon-position, orientation, pitch and altitude is read from the image. You can adjust the values in case image doesn't contain all the settings. With the checkbox, the altitude can be made absolute to sea level or relative to the ground. The camera is positioned by using the goto button of the layer:
This layer type takes polygons from shapefiles. After placing the polygons on the ground, blocks are created by extruding the polygons upward and downward. Downward extrusion is useful to fill the gap between the polygon and the ground in uneven terrain.
The amount can be controlled with the sliders for the height and negative height in the layer settings. This values effect all polygons in a shapefile, that have no such value specified in its attributes. There are four attributes to customize single polygon:
The colors-strings are comma-separated rgb-triples to specify the red, green and blue color part, each in the range from 0 to 1. Some examples:
This layer type uses 2.5D shapefile polygons to create water surfaces. The z-value determines the height absolute to sea level in meter. There are three attributes available:
If the attributes "waveLen" and "waveHgt" don't exist or if the entries are zero, the values from the global water surface will be used instead.
