Detailed Description

voxel terrain class

Constructor & Destructor Documentation

iVoxelTerrain()

igor::iVoxelTerrain::iVoxelTerrain	(	iVoxelTerrainGenerateDelegate	generateVoxelsDelegate,
		iVoxelTerrainPlacePropsDelegate	placePropsDelegate,
		uint32	lodCount = 11,
		uint32	voxelBlockSetupDistance = 4,
		const iaVector3I &	maxDiscoveryBoundaries = iaVector3I(100000, 100000, 100000)
	)

initializes voxel terrain

Parameters

generateVoxelsDelegate	callback to generate voxel data
lodCount	count of level of detail allowed range is 2-11 (right now the lowest LOD is not visible)
voxelBlockSetupDistance	distance in blocks of the lowest level of detail to be generated and visible when in range
maxDiscoveryBoundaries	optionally adding boundaries to the discovery area. Values are in voxel block coordinates of the lowest LOD

castRay()

bool igor::iVoxelTerrain::castRay	(	const iaVector3I &	from,
		const iaVector3I &	to,
		iaVector3I &	outside,
		iaVector3I &	inside
	)

casts ray to voxels to detect intersection

Parameters

	from	from where the ray is cast
	to	to where the ray is cast to
[out]	outside	if there is an intersection this is the last voxel right before
[out]	inside	if there is an intersection this is the first voxel with density greater zero

Returns

true if there was an intersection
