vcgdemomaker(1)
NAME
vcgdemomaker - produces demo specifications for vcg
SYNOPSIS
vcgdemomaker outfile mode size
DESCRIPTION
- Vcgdemomaker creates a vcg specification and writes it to
- outfile. The mode determines the kind of specification and size
- the size of the specified graph. The specification can be read
- and visualized by the VCG tool.
MODI
- -unarytree
- generates an unary tree, i.e. a linear sequence
- of nodes. size is the number of nodes - 1, i.e. the depth of the
- tree.
- -binarytree
- generates a binary tree of depth size. Each
- node has two successors.
- -ternarytree
- generates a ternary tree of depth size. Each
- node has 3 successors.
- -leveltree
- generates a leveled tree of depth size. Each
- node has 2 normal successors, and further a list of nodes as suc
- cessors at the same level to the left and right. These lists
- contain at most 2 nodes, which itself are leveled trees. These
- trees are used to check the nearedge feature.
- -twolevelcross
- generates a cross graph. This is a biparti
- tioned graph of connected parts of 4 nodes forming a cross. Size
- is the number of nodes and should be even. This graph is gener
- ated in an ugly format to check the algorithm of reducing of
- crossing in the VCG tool.
- -allconnect
- generates a graph where all pairs of node form
- an edge. Size is the number of nodes. Note that if we have n
- nodes, we have about n*n/2 edges which is a lot. Thus it is rec
- ommended not to use this with more than 40 nodes.
- -netgraph generates a regular 4-ary network of triangular
- shape with about size nodes. This mesh graph can be used to check
- the capacity of the tool, the view mechanism and the algorithm of
- reducing of crossing in the VCG tool.
- -randomgraph
- generates a randomized 4-ary network. Starting
- from the regular 4-ary network of triangular shape with about
- size nodes, this network is produced by creating random holes.
- Thus, this graph has less than size nodes.
- -net2graph
- generates a regular 4-ary network of rhomboid
- shape with about size nodes.
- -random2graph
- generates a randomized 4-ary network. Starting
- from the regular 4-ary network of rhomboid shape with about size
- nodes, this network is produced by creating random holes. Thus,
- this graph has less than size nodes.
