Window Conditions
Performance Optimized For: Factors Affecting Performance:
• Window unobscured or obscured only by
overlay windows
• Window obscured by other image plane
windows
• Backing store enabled (on supported
devices)
Fill Area Set Primitives
Performance Optimized For: Factors Affecting Performance:
• Best: shared vertex primitives with many
vertices:
o ptri_strip3_data (C), ptst3d
(FORTRAN)
o pset_of_fill_sets3_data (C), psfas3
(FORTRAN)
o pquad_mesh3_data (C), pqm3d
(FORTRAN)
• Good: single-polygon primitives:
o pfill_area_set3 (C), pfas3
(FORTRAN)
o pfill_area3 (C), pfa3 (FORTRAN)
o pfill_area_set3_data (C), pfas3d
(FORTRAN)
• True colour mapping in a direct colour
environment
• Best: edging off
• Fair: edging on
• More than 64 vertices in a single facet
• Multiple Fill Areas in a set
• 2D polygons
• Pseudo colour mapping method
• Indexed colour environment
• These vertex data:
o Indirect colour
o No vertex normals (when lighting is
enabled)
Polyline Primitives
Performance Optimized For: Factors Affecting Performance:
• Best: single polylines with many vertices
per call:
o ppolyline_set3_colr (C), ppls3c
(FORTRAN)
o ppolyline3 (C), ppl3 (FORTRAN)
o ppolyline (C), ppl (FORTRAN)
• Polyline sets with multiple disjoint sets:
o pgdp_u14 (C), pu014 (FORTRAN)
o Plus those noted above with
multiple sets
• These vertex data:
o Indirect colour
o RGB colour
• Pseudo colour mapping method
