Interfaces

CameraProps

Prop	Type	Required	Notes
ref	{current: CameraRef}	false	reference of the camera for accessing it's properties
initialPosition	CameraPosition	false	set the position of the camera in geographic coordinates. The origin of coordinates is the object itself

CameraRef

Prop	Type	Required	Notes
setCameraPosition	(position: CameraPosition) => any	true	imperatively sets the camera position based on the provided geographic coordinates

setCameraPosition:

ModelProps

Prop	Type	Required	Notes
ref	{current: ModelRef}	false	reference of the 3d model for accessing it's properties
scale	number	false	scale of the 3d model, defaults to 1
positionX	number	false	x coordinate in the world of the 3d model
positionY	number	false	y coordinate in the world of the 3d model
rotationX	number	false	rotation in x axis of the model
rotationY	number	false	rotation in y axis of the model
rotationY	number	false	rotation in z axis of the model
color	CSSProperties['color']	false	color of the 3d model, defaults to "grey"
geometryProps	(geometry: BufferGeometry) => BufferGeometry	false	Perform some processing to the models geometry

FloorProps

Prop	Type	Required	Notes
gridWidth	number	false	if specified, a grid will be drawn in the floor with this width
gridLength	number	false	if specified, a grid will be drawn in the floor with this length

ModelDimensions

Prop	Type	Notes
boundingRadius	number	the radius of the bounding sphere of the 3d model before scaling
width	number	width of the 3d object
height	number	height of the 3d object
length	number	length of the 3d object

CameraPosition

Prop	Type	Required	Notes
latitude	number	false	camera's position latitude, it should be a number between - Math.PI / 2 and Math.PI / 2, if the number exceeds the limits it will be clamped
longitude	number	false	camera's position longitude, it should be a number between - Math.PI and Math.PI, if the number exceeds the limits it will be clamped
distance	number	false	the distance factor between the object and the camera. This is a factor relative to the object size or the grid size if it's specified
