NavigationOperator

class cee.NavigationOperator()

The Operator class is the base class for all operators. A name is required for all operators, and the name is used to identify the operator in the cee.OperatorStack.

Operators contain optional methods that correspond to the different events that may occur in the view. When an operator is set on a View, the operator can interact with its ownerView, but only that view. The cee.Viewer sets the events listeners internally, and then fires the corresponding Operator event handler method when the event is recieved.

Constructors

NavigationOperator.constructor(name)

Arguments:

• name (string) – None

Return type:

NavigationOperator

Accessors

cee.config()

The navigation configuration. Specify what should happen on mouse and touch input

Return type:

OperatorConfig <NavigationType>

cee.config(config)

Arguments:

• config (OperatorConfig) – None

Return type:

void

cee.invertWalkZoom()

Invert the zoom direction of the mouse wheel

Return type:

boolean

cee.invertWalkZoom(invert)

Arguments:

• invert (boolean) – None

Return type:

void

cee.minWalkTargetDistance()

The minimum walk target minTargetDistance

For walk navigation, this is used to control how much the navigation should slow down when getting close to the rotation point. The walk speed is dynamic so you can interact with large models. Depending on your model size, you might want to adjust this parameter.

The default is undefined (automatic), which will be interpreted as 1/10 of the current view bounding box.

Return type:

number

cee.minWalkTargetDistance(minTargetDistance)

Arguments:

• minTargetDistance (number) – None

Return type:

void

cee.mouseWheelZoomAndWalkBehavior()

Determine mouse wheel zoom and walk behavior

This setting will only have effect if mouse wheel is configured to perform zoom or walk navigation.

Return type:

MouseWheelZoomAndWalkBehavior

cee.mouseWheelZoomAndWalkBehavior(behavior)

Arguments:

• behavior (MouseWheelZoomAndWalkBehavior) – None

Return type:

void

cee.name()

The name of the operator. Built-in operator names can be referenced by the StandardOperator enum.

Return type:

string

cee.ownerView()

Returns the View that this operator is set on. If the operator is not on a view’s cee.OperatorStack, null is returned.

Return type:

View

cee.rotationAxis()

The axis around which the model should be rotated. Set undefined/null to not constrain to an axis.

Return type:

Vec3Like

cee.rotationAxis(axis)

Arguments:

• axis (Vec3Like) – None

Return type:

void

cee.rotationPoint()

The current rotation point

Return type:

Vec3Like

cee.rotationPoint(rotationPoint)

Arguments:

• rotationPoint (Vec3Like) – None

Return type:

void

cee.rotationSensitivity()

Rotation sensitivity

Sensitivity factor controlling how sensitive the mouse is when doing rotations.

Default 1.0

Return type:

number

cee.rotationSensitivity(sensitivity)

Arguments:

• sensitivity (number) – None

Return type:

void
