MGH_ISOSURFACE__DEFINE

Class Name


  MGH_IsoSurface

Purpose


  This class displays a 3-D numeric array as an iso-surface with an
  adjustable threshols.

Object Creation Calling Sequence


  mgh_new, 'MGH_IsoSurface', values

Inputs


  values A 3D array of numeric data

Properties


  The following properties are supported (amongst others):
    BYTE_RANGE (Init,Get)
      The range of byte values to which the data range is to be mapped.
    DATA_RANGE (Init,Get,*Set)
      The range of data values to be mapped onto the indexed color range for the
      density surface and the colour bar. Data values outside the range are mapped
      to the nearest end of the range. If not specified, DATA_RANGE is calculated
      when the density surface is created, The DATA_RANGE property can be changed
      after object initialisation only if the STORE_DATA property has been set.
    PALETTE (Init,Get,Set)
      A reference to the palette defining the byte-color mapping.
    STORE_DATA (Init,Get):
      This property is passed to the density surface. It determines whether
      data values are stored with the surface.
