hydroogmap::OgRayTracer< CellTracer > Class Template Reference #include <ograytracer.h> List of all members. Public Member Functions bool  trace (int x0, int y0, int x1, int y1) Detailed Description template<class CellTracer = SafeLosCellTracer> class hydroogmap::OgRayTracer< CellTracer > Author: Alex Brooks Templated over the CellTracer so that the compiler can optimise fuck out of the thing. Needs to be supplied with the CellTracer class, which matches the interface of SafeLosCellTracer above. Member Function Documentation template<class CellTracer> SOEXPORT bool hydroogmap::OgRayTracer< CellTracer >::trace (  int  x0, int  y0, int  x1, int  y1 )    Trace from cell (x0,y0) to cell (x1,y1), inclusive. Sets the endpoints which were reached. CellTracer.traceCell(x,y) is applied to every cell along the trace. rayTrace is guaranteed to start tracing from the (x0,y0) end. If traceCell ever returns false, tracing stops. If we trace right out to (x1,y1), we call cellTracer.traceSucceeded(x1,y1). Uses Bresenham's Line Algorithm (so it's fast). Returns: true: we traced out to (x1,y1) false: the trace was short-circuited The documentation for this class was generated from the following file: ograytracer.h
