DCL:GRPH1:Summary:Output Primitives
There are 2 interpolation functions.
The following are the parameters for SGpGET/SGpSET for this function.
LLNINT (L) A flag specifying whether linear interpolation will be made. (Default value: .FALSE.) LGCINT (L) A flag specifying whether a great circle interpolation will be made. (Default value: .TRUE.). RDX, RDY (R) The interpolation interval. The length of a segment in the interpolation will not exceed this value. (Default value: (5., 5.))
Clippings will be performed in the following locations.
The following are the parameters for SGpGET/SGpSET for this function.
LCLIP (L) A flag specifying whether clipping will be made in the viewport. (Default value: .FALSE.) VXMIN, VXMAX, VYMIN, VYMAX (R) The viewport. Normally set by SGSVPT. TXMIN, TXMAX, TYMIN, TYMAX (R) The clipping boundaries in TC. (Default values: -180.0, +180.0, -90.0, +90.0) IRMOD (I) A parameter specifying whether the tone boundary lines will be connected in the clockwise or counter-clockwise direction. (See 1.7.5 ) (Default value: 0).
The clipping of a viewport can be switched ON/OFF with 'LCLIP'. Other clippings will always be performed. In orthographic projections, the line segments on the reverse side will also be drawn when the default value for the clipping boundary in TC is used. To draw only lines on the front side, set 'TYMIN' to 0.
