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
