Detailed Description

the U4DRayCast class test intersections between a ray and 3D objects

Member Function Documentation

hit()

bool U4DEngine::U4DRayCast::hit	(	U4DRay &	uRay,
		U4DModel *	uModel,
		U4DTriangle &	uTriangle,
		U4DPoint3n &	uIntersectionPoint,
		float &	uIntersectionParameter
	)

Tests intersection between a ray and a 3D model and returns the face (triangle) hit.

Parameters

uRay	Ray used for the intersection
uModel	3D model to test intersection with ray. You must enable the mesh Manager on the model before using this method.
uTriangle	face (triangle) of the 3D model intersection with the ray
uIntersectionPoint	intersection 3D point
uIntersectionParameter	intersection parameter, i.e. time

Returns

face of 3d model intersecting with the given ray, along with the intersection point and parameter

Note, to use this method, you need to enable the mesh manager of the 3D model. i.e. enableMeshManager(2)
