Member Function Documentation

virtual bool iTerrainCollider::Collide	(	iTerrainCell *	cell,
		iCollider *	collider,
		float	radius,
		const csReversibleTransform &	trans,
		bool	oneHit,
		iTerrainCollisionPairArray *	pairs
	)			[pure virtual]

Collide collider with cell.

Parameters:

	cell	cell
	collider	collider
	radius	radius of the bounding sphere surrounding the given set of triangles (used for fast rejection)
	trans	triangle set transformation (vertices' coordinates are specified in the space defined by this transformation)
	oneHit	if this is true, than stop on finding the first collision pair; otherwise, detect all collisions
	points	destination collision pair array

Returns:

true if there were any collisions, false if there were none

virtual csTerrainColliderCollideSegmentResult iTerrainCollider::CollideSegment	(	iTerrainCell *	cell,
		const csVector3 &	start,
		const csVector3 &	end
	)			[pure virtual]

Collide segment with cell.

Parameters:

	cell	cell
	start	segment start (specified in object space)
	end	segment end (specified in object space)

Returns:

a csTerrainColliderCollideSegmentResult instance indicating what we hit.

virtual bool iTerrainCollider::CollideSegment	(	iTerrainCell *	cell,
		const csVector3 &	start,
		const csVector3 &	end,
		csVector3 &	hitPoint
	)			[pure virtual]

Collide segment with cell.

Stops on finding the first intersection point (the closest to the segment start).

Parameters:

	cell	cell
	start	segment start (specified in object space)
	end	segment end (specified in object space)
	hitPoint	receives the intersection point

Returns:

true if there was an intersections, false if there was none

virtual bool iTerrainCollider::CollideSegment	(	iTerrainCell *	cell,
		const csVector3 &	start,
		const csVector3 &	end,
		bool	oneHit,
		iTerrainVector3Array *	points
	)			[pure virtual]

Collide segment with cell.

Parameters:

	cell	cell
	start	segment start (specified in object space)
	end	segment end (specified in object space)
	oneHit	if this is true, than stop on finding the first intersection point (the closest to the segment start); otherwise, detect all intersections
	points	destination point array

Returns:

true if there were any intersections, false if there were none

virtual bool iTerrainCollider::CollideTriangles	(	iTerrainCell *	cell,
		const csVector3 *	vertices,
		size_t	tri_count,
		const unsigned int *	indices,
		float	radius,
		const csReversibleTransform &	trans,
		bool	oneHit,
		iTerrainCollisionPairArray *	pairs
	)			[pure virtual]

Collide set of triangles with cell.

Parameters:

	cell	cell
	vertices	vertex array
	tri_count	triangle count
	indices	vertex indices, 3 indices for each triangle
	radius	radius of the bounding sphere surrounding the given set of triangles (used for fast rejection)
	trans	triangle set transformation (vertices' coordinates are specified in the space defined by this transformation)
	oneHit	if this is true, than stop on finding the first collision pair; otherwise, detect all collisions
	points	destination collision pair array

Returns:

true if there were any collisions, false if there were none

virtual csPtr<iTerrainCellCollisionProperties> iTerrainCollider::CreateProperties

(

)

[pure virtual]

Create an object that implements iTerrainCellCollisionProperties This object will be stored in the cell.

This function gets invoked at cells creation.

Returns:

properties object
