Window Conditions
Performance Optimized For:
Factors Affecting Performance:
•
Window unobscured or obscured only by
overlay windows
•
Window obscured by many other image
plane windows
•
Backing store enabled (on supported
devices)
FillArea Primitives
Performance Optimized For:
Factors Affecting Performance:
•
Best: shared vertex primitives with many
vertices:
o
PEXTriangleStrip,
PEXExtTriangleStrip,
PEXOCCTriangleStrip
o
PEXSetOfFillAreaSets,
PEXExtSetOfFillAreaSets,
PEXOCCIndexedFillAreaSets
o
PEXOCCTriangles
o
PEXQuadrilateralMesh,
PEXExtQuadrilateralMesh,
PEXOCCQuadrilateralMesh
•
Good: single-polygon primitives:
o
PEXFillAreaSetWithData,
PEXExtFillAreaSetWithData,
PEXFillAreaSet,
PEXOCCFillAreaSet, PEXFillArea,
PEXFillAreaWithData
•
Color approximation type
PEXColorSpace
•
Best: edging off
Fair: edging on
•
More than 64 vertices in a single facet
•
Multiple Fill Areas in a set
•
Color approximation type
PEXColorRange
•
Polygon offset ON (except when supported
by hardware)
•
2D polygons:
o
PEXFillAreaSet2D,
PEXFillArea2D
•
These vertex data:
o
PEXColorTypeIndexed
color
o
No vertex normals (when lighting is
enabled)
Polyline Primitives
Performance Optimized For:
Factors Affecting Performance:
•
Best: polylines with or without move/draw
flags, many vertices per call:
o
PEXPolylineSetWithData
(single
set),
PEXOCCPolylines
•
Polyline sets with multiple short disjoint
sets:
o
PEXPolylineSetWithData
(multiple
sets)
•
Single short polylines:
o
PEXPolyline
,
PEXOCCPolyline
•
These vertex data:
o
Color per vertex
(
PEXColorTypeIndexed
or
PEXColorTypeRGB
)
•
Color approximation type
PEXColorRange
