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)
Polygon Primitives
Performance Optimized For: Factors Affecting Performance:
• Best: shared vertex primitives with many
vertices:
o triangular_strip,
triangular_strip_with_data
o polyhedron_with_data
o quadrilateral_mesh,
quadrilateral_mesh_with_data
o polytriangle_with_data,
polyquad_with_data
• Good: polygon3d
• shade_mode set to CMAP_FULL
• Edging:
o Best: edging off
o Great: SET_POLYGON_OFFSET
enabled, with hardware support
o Good: SET_POLYGON_OFFSET
enabled, with software support
o Fair: edging on
• More than 64 vertices in a single facet
• 2D polygons
• Device coordinate polygons
• shade_mode set to
CMAP_NORMAL or
CMAP_MONOTONIC
• Partial polygons
• These vertex formats:
o Indirect color
o Intensity
o No vertex normals (when lighting is
enabled)
o Non-unit normals
Polyline Primitives
Performance Optimized For: Factors Affecting Performance:
• Best: polyline3d and polyline_with_data3d
with or without move/draw flags, many
vertices per call
• These vertex formats:
o RGB/vertex
o Indirect color
o Intensity
• Individual moves and draws with move3d
and draw3d
• shade_mode set to CMAP_MONOTONIC
