FillArea Primitives
Performance Optimized For: | Factors Affecting Performance: | |||
• Best: shared vertex primitives with many | • More than 64 vertices in a single facet | |||
vertices: | • Multiple Fill Areas in a set | |||
o | PEXTriangleStrip, | • Color approximation type PEXColorRange | ||
| PEXExtTriangleStrip, | • Polygon offset ON (except when supported | ||
o | PEXOCCTriangleStrip |
| by hardware) | |
PEXSetOfFillAreaSets, | • | 2D polygons: | ||
| PEXExtSetOfFillAreaSets, |

PEXOCCTriangles | • | These vertex data: | ||
o | PEXQuadrilateralMesh, |

Polyline Primitives
Performance Optimized For: | Factors Affecting Performance: | ||
• Best: polylines with or without move/draw | • | These vertex data: | |
flags, many vertices per call: |

| set), PEXOCCPolylines | • | PEXColorTypeRGB) |
• Polyline sets with multiple short disjoint | Color approximation type | ||
sets: | PEXPolylineSetWithData (multiple |

o |
|

| sets) |
|
|
• Single short polylines: |
|
| |
o | PEXPolyline, PEXOCCPolyline |
