LowDim Sample
LowDim Sample demonstrates programming Point Set objects

The application
By default the application loads LowDim.mdg with three points and per vertex
colors. The form displays all properties of the set.
Changing the point count edit box and pressing Tab key adds or removes points
to the set. Zoom ou tto see the new points. New points are created at the default location (0,0,0) and with
default color.
Implementation
LowDimDlg::Init() function obtains
ISectionPointSet
interface from the first ISection
in the model and gets access to its Point Array by quirking it from the
ISectionPointSet. and storing it
in m_iArray2 variable. To retrieve coordinates of the points
IMatrixData
is obtained with a call to ISectionPointSet.GetPoints.
IMatrixData
implemented by the Color Array is obtained via
ISectionPointSet.GetColors and stored into the m_iMatrixColor variable.
OnPointCountChanged() method handles changes in size of the point array
by adding or removing last points via m_iArray2.
All other operations are comparatively straightforward.
