POLYTYPE_ATEX_LIT, POLYTYPE_PTEX_LIT – Polygon rendering mode type Allegro game programming library. Synopsis#include <allegro.h> #define POLYTYPE_ATEX_LIT #define POLYTYPE_PTEX_LIT DescriptionLike POLYTYPE_ATEX and POLYTYPE_PTEX, but the global color_map table (for 256-color modes) or blender function (for non-MMX truecolor modes) is used to blend the texture with a light level taken from the `c’ value in the vertex structure….
POLYTYPE_ATEX – Polygon rendering mode type Allegro game programming library. Synopsis#include <allegro.h> #define POLYTYPE_ATEX DescriptionAn affine texture mapped polygon. This stretches the texture across the polygon with a simple 2d linear interpolation, which is fast but not mathematically correct. It can look OK if the polygon is fairly small or flat-on to the camera, but…
PMWEBAPI – introduction to the Performance Metrics Web Application Programming Interface OverviewThe PMWEBAPI interface is a binding of a subset of the PMAPI to the web.

PCPIntro – introduction to the Performance Co-Pilot (PCP) libraries IntroductionPerformance Co-Pilot (PCP) is a toolkit designed for monitoring and managing system-level performance. The PCP libraries support the APIs required to create new performance monitoring tools and new agents (or PMDAs) to export performance data. The libpcp library is used in both cases. The libpcp_pmda library…
