Sandbox Camera Auto Radius and Target

Karim_Salam · November 20, 2023, 2:19pm

Hello,

I’m working on a project that renders a model based on the user input, so how can i have the camera to be in the same state is in babylonjs’s sandbox, whatever is the size of the model the radius limits get automatically set properly and the camera looks into the model’s center, is there a way to have it exactly the same as the sandbox ?

Thank you.

This is what the sandbox uses: Camera Behaviors | Babylon.js Documentation

github.com

BabylonJS/Babylon.js/blob/master/packages/tools/sandbox/src/components/renderingZone.tsx#L187


      
          // Enable camera's behaviors

          camera.useFramingBehavior = true;

          

          const framingBehavior = camera.getBehaviorByName("Framing") as FramingBehavior;

          framingBehavior.framingTime = 0;

          framingBehavior.elevationReturnTime = -1;

          

          if (this._scene.meshes.length) {

              camera.lowerRadiusLimit = null;

          

              const worldExtends = this._scene.getWorldExtends(function (mesh) {

                  return mesh.isVisible && mesh.isEnabled();

              });

              framingBehavior.zoomOnBoundingInfo(worldExtends.min, worldExtends.max);

          }

          

          if (this.props.autoRotate) {

              camera.useAutoRotationBehavior = true;

          }

          

          if (this.props.cameraPosition) {
