NavigationConfig

class cee.NavigationConfig()

Navigation configuration for a view.

Specify how mouse and touch input should be used to navigate the view (move the camera).

Note: To use the right mouse button (either rightMouseButton or leftAndRightMouseButtons), you need to disable the default context menu in the browser (see example below).

Example on how to configure “Ceetron style” navigation:

// Disable context menu - Required for enableMouseButtonTracking
canvas.addEventListener("contextmenu", (event) => { event.preventDefault()});

// Enable mouse tracking (so we can use leftAndRightMouseButtons)
viewer.enableMouseButtonTracking(true);

// Ceetron style navigation
const navConfig = view.navigation.config;
navConfig.leftMouseButton.noModifier =cee.NavigationType.PAN;
navConfig.rightMouseButton.noModifier =cee.NavigationType.ROTATE;
navConfig.leftAndRightMouseButtons.noModifier =cee.NavigationType.WALK;
navConfig.wheelOrPinch = cee.NavigationType.WALK;
