Examples of org.earth3d.jearth.model.PartsObject

org.earth3d.jearth.model.PartsObject
Parses a data block in the "parts" format. This format can put several documents into a single file. The file starts with a single line containing a number that tells us how many blocks are in the file. Each block starts with a line containing a number describing the size of the following block. Then the block itself follows. @author webmaster@earth3d.org
