This section includes only the simplest primitives most commonly used as structure element.
polymark : is produced by the PPM (2D primitive) or PPM3 (3D primitive) function
and generates a marker (a ., or a *, etc.) at each point on the list of points given as function parameters.
polyline : is produced by the PPL (2D primitive) or PPL3 (3D primitive) function
and generates a series of straight segments joining the points on the list of points given as function parameters, in the order in which they are entered.
and is used to define a closed, planar fill area, and to fill it with a plain color, cross-hatching, or pattern. The list of points given as function parameters defines the outside contour of the fill area.
fill area set : is produced by the PFAS (2D primitive) or PFAS3 (3D primitive) function
and is used to define a list of closed, coplanar fill areas, and to fill them with plain colors, cross-hatching, or patterns. The fill areas may be separate or one inside the other. The list of lists of points given as function parameters defines the set of outside contours of the fill areas.
text : is produced by the PTX (2D primitive) or PTX3(3D primitive) function
and generates a character string either in the 2D plane, or in any plane in 3D space (for the PTX3 primitive).
annotate text : is produced by the PATR (2D primitive) or PATR3 (3D primitive) function
function and generates a character string for annotating any point in 3D space. This character string is always presented in the same plane as the display surface.
