DynamicsVisualizer.Scene¶
create¶
args: None
This method creates the scene from the self.model and renders it onto the canvas.
_createRenderer¶
args: None
- Creates a webGL Renderer
with a default background color.
_addDefaultLightsandCameras¶
args: None
This method adds a default light and a Perspective camera to the initial visualization
_addAxes¶
args: None
Adds a default system of axes to the initial visualization.
_addTrackBallControls¶
args: None
Adds Mouse controls to the initial visualization using Three’s TrackballControls library.
_resetControls¶
args: None
Resets the scene camera to the initial values(zoom, displacement etc.)
addObjects¶
args: None
Adds the geometries loaded from the JSON file onto the scene. The file is saved as an object in self.model and then rendered to canvas with this function.
addCameras¶
args: None
Adds the cameras loaded from the JSON file onto the scene. The cameras can be switched during animation from the switch cameras UI button.

Takes a time value as the argument and renders the simulation data corresponding to that time value.
stopAnimation¶
args: None
Stops the animation, and sets the current time value to initial.
_removeAll¶
args: None
Removes all the geometry elements added to the scene from the loaded scene JSON file. Keeps the default elements, i.e. default axis, camera and light.
_blink¶
