Function Documentation

template<typename VolumeType >

bool PolyVox::aStarDefaultVoxelValidator	(	const VolumeType *	volData,
		const Vector3DInt32 &	v3dPos
	)

This function provides the default method for checking whether a given voxel is valid for the path computed by the AStarPathfinder.

Using this function, a voxel is considered valid for the path if it is inside the volume and if its density is below that returned by the voxel's getDensity() function.

Returns:: true is the voxel is valid for the path

template<typename VolumeType , typename Callback >

RaycastResult PolyVox::raycastWithDirection	(	VolumeType *	volData,
		const Vector3DFloat &	v3dStart,
		const Vector3DFloat &	v3dDirectionAndLength,
		Callback &	callback
	)

Cast a ray through a volume by specifying the start and a direction.

The ray will move from v3dStart along v3dDirectionAndLength, calling callback for each voxel it passes through until callback returns false. In this case it returns a RaycastResults::Interupted. If it passes from start to end without callback returning false, it returns RaycastResults::Completed.

Note:: These has been confusion in the past with people not realising that the length of the direction vector is important. Most graphics API can provide a camera position and view direction for picking purposes, but the view direction is usually normalised (i.e. of length one). If you use this view direction directly you will only iterate over a single voxel and won't find what you are looking for. Instead you must scale the direction vector so that it's length represents the maximum distance over which you want the ray to be cast.

Parameters:

volData	The volume to pass the ray though
v3dStart	The start position in the volume
v3dDirectionAndLength	The direction and length of the ray
callback	The callback to call for each voxel

Returns:: A RaycastResults designating whether the ray hit anything or not

RaycastResult PolyVox::raycastWithEndpoints	(	VolumeType *	volData,
		const Vector3DFloat &	v3dStart,
		const Vector3DFloat &	v3dEnd,
		Callback &	callback
	)

Cast a ray through a volume by specifying the start and end positions.

The ray will move from v3dStart to v3dEnd, calling callback for each voxel it passes through until callback returns false. In this case it returns a RaycastResults::Interupted. If it passes from start to end without callback returning false, it returns RaycastResults::Completed.

Parameters:

volData	The volume to pass the ray though
v3dStart	The start position in the volume
v3dEnd	The end position in the volume
callback	The callback to call for each voxel

Returns:: A RaycastResults designating whether the ray hit anything or not
