Detailed Description

project a polyline onto a terrain

vtkProjectedTerrainPath projects an input polyline onto a terrain. (The terrain is defined by a 2D height image and is the second input to the filter.) The polyline projection is controlled via several modes as follows. 1) Simple mode projects the polyline points onto the terrain, taking into account the height offset instance variable. 2) Non-occluded mode insures that no parts of the polyline are occluded by the terrain (e.g. a line passes through a mountain). This may require recursive subdivision of the polyline. 3) Hug mode insures that the polyine points remain within a constant distance from the surface. This may also require recursive subdivision of the polyline. Note that both non-occluded mode and hug mode also take into account the height offset, so it is possible to create paths that hug terrain a certain distance above it. To use this filter, define two inputs: 1) a polyline, and 2) an image whose scalar values represent a height field. Then specify the mode, and the height offset to use.

An description of the algorithm is as follows. The filter begins by projecting the polyline points to the image (offset by the specified height offset). If the mode is non-occluded or hug, then the maximum error along each line segment is computed and placed into a priority queue. Each line segment is then split at the point of maximum error, and the two new line segments are evaluated for maximum error. This process continues until the line is not occluded by the terrain (non-occluded mode) or satisfies the error on variation from the surface (hug mode). (Note this process is repeated for each polyline in the input. Also, the maximum error is computed in two parts: a maximum positive error and maximum negative error. If the polyline is above the terrain–i.e., the height offset is positive–in non-occluded or hug mode all negative errors are eliminated. If the polyline is below the terrain–i.e., the height offset is negative–in non-occluded or hug mode all positive errors are eliminated.)

Warning

This algorithm requires the entire input image to be in memory, hence it may not work for extremely large images.

The input height image is assumed to be positioned in the x-y plane so the scalar value is the z-coordinate, height value.

A priority queue is used so that the 1) the total number of line segments can be controlled, and 2) the algorithm can terminate when the errors in the queue are less than the specified error tolerance.
