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.
