AtlasGeomChunkTracer Class Reference [Atlas Resource System]

#include <atlasGeomCollision.h>

Inheritance diagram for AtlasGeomChunkTracer:

Detailed Description

Trace rays against an AtlasGeomChunk.

Public Member Functions

AtlasGeomChunkTracer (AtlasGeomChunk *chunk)

bool castRay (const Point3F &start, const Point3F &end, RayInfo *info)

Perform a raycast against the quadtree.

Protected Member Functions

const AtlasGeomChunk::ColNode * findSquare (const U32 &level, const Point2I &pos) const

virtual const F32 getSquareMin (const U32 &level, const Point2I &pos) const

Children better implement these! They return min/max height bounds of the specified square.

virtual const F32 getSquareMax (const U32 &level, const Point2I &pos) const

virtual bool castLeafRay (const Point2I pos, const Point3F &start, const Point3F &end, const F32 &startT, const F32 &endT, RayInfo *info)

And this does checks on leaf nodes.

bool castRayTriangle (Point3F orig, Point3F dir, Point3F vert0, Point3F vert1, Point3F vert2, F32 &t, Point2F &bary)

Protected Attributes

AtlasGeomChunk * mChunk

Point3F mRayDelta

Point3F mRayStart

Point3F mRayEnd

Point3F mScale

Point3F mOffset

bool AtlasGeomChunkTracer::castRay	(	const Point3F &	start,
		const Point3F &	end,
		RayInfo *	info
	)

Perform a raycast against the quadtree.

This expects positions in FILE space, not CHUNK space.

Reimplemented from QuadTreeTracer.
