Package WildMagic.LibImagics.Extraction

Class ExtractSurfaceTetra.Vertex

  • Enclosing class:
    ExtractSurfaceTetra
    protected class ExtractSurfaceTetra.Vertex
extends java.lang.Object
    A rational representation of a level set vertex. The rational form allows for exact look-ups in a hash map of vertices. The class extends Object for hashing support.

      • m_iXNumer

        public int m_iXNumer
        Vertices are stored as rational numbers (xn/xd,yn/yd,zn/zd). This supports removing redundant vertices that occur because of extraction in adjacent voxels.

      • m_iXDenom

        public int m_iXDenom
        Vertices are stored as rational numbers (xn/xd,yn/yd,zn/zd). This supports removing redundant vertices that occur because of extraction in adjacent voxels.

      • m_iYNumer

        public int m_iYNumer
        Y rational

      • m_iYDenom

        public int m_iYDenom
        Y rational

      • m_iZNumer
