Hi,
I'm am currently drawing just a 3d model 2d-plane with an image to show reference to direction on the path. These objects are selectable but this can become more difficult when you adjust the tilt to be horizontal to the object.
I was wondering if there was a way to adjust the click size/range of particular objects. Currently I have accomplished this by including a BoxGraphic with the entity with a very low alpha to increase the height of the area of selection. I don't like this because it includes 2 primitives for each object and was hoping there was a better way.
new Cesium.Entity({
id: waypoints.Id,
position: position,
orientation: Cesium.Transforms.headingPitchRollQuaternion(position, bearing, 0.0, 0.0),
model: new Cesium.ModelGraphics({
uri: RouteEntityHandler.WAYPOINT_MODEL,
minimumPixelSize: RouteEntityHandler.WAYPOINT_PIXEL,
castShadows: false,
receiveShadows: false
}),
// Adding a surrounding box graphics to increase click radius for waypoint
box: new Cesium.BoxGraphics({
material: Cesium.Color.ALICEBLUE.withAlpha(0.01),
dimensions: new Cesium.Cartesian3(5000.0, 5000.0, 5000.0)
})
});
Click handler:
private handleLeftClick(position: Cesium.Cartesian2): void {
// do deep picking at the clicked mouse position
let pickedObjects = this.scene.drillPick(position);
console.log(pickedObjects);
}
Using Cesium 1.24 with latest Chrome & Windows 10.
Thanks!
