Window Conditions Performance Optimized For: Factors Affecting Performance: • Window unobscured or obscured only by • Window obscured by many other image overlay windows plane windows • Backing store enabled (on supported devices) Polygon Primitives Performance Optimized For: Factors Affecting Performance: • Best: shared vertex primitives with many • More than 64 vertices in a single facet vertices: • 2D polygons o triangular_strip, • Device coordinate polygons 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 • 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 enabled, with hardware support o Good: SET_POLYGON_OFFSET enabled, with software support o Fair: edging on Polyline Primitives Performance Optimized For: Factors Affecting Performance: • Best: polyline3d and polyline_with_data3d • These vertex formats: with or without move/draw flags, many o RGB/vertex vertices per call o Indirect color o Intensity • Individual moves and draws with move3d and draw3d • shade_mode set to CMAP_MONOTONIC Page 113 Graphics Administration Guide for HP-UX 10.20
