setView
Syntax
Description
Examples
Create a custom view of the 3D environment using the createViewpoint
function. Use the setView
function to set the view in the Simulation 3D Viewer window.
Create a world object using the sim3d.World
object.
world = sim3d.World();
Create a box actor in the 3D environment using the sim3d.Actor
object. Add the box actor to the world.
box = sim3d.Actor(ActorName='Box'); createShape(box,'box',[0.5 0.25 0.25]); box.Color = [1 0 0]; add(world,box);
Create a custom view using the createViewpoint
function.
view = createViewpoint(world);
view.Name = 'View';
view.Translation = [-4 0 0];
Set the view of the 3D environment to display in the Simulation 3D Viewer window. If you do not set the view, the software sets the default view.
setView(world,view);
Run the simulation.
sampletime = 0.01; stoptime = 10; run(world,sampletime,stoptime);
Create multiple views of the 3D environment using the createViewpoint
function. Use the setView
function to set the view in the Simulation 3D Viewer window.
Create a world object using the sim3d.World
object.
world = sim3d.World(Output=@outputImpl);
Create a box actor in the 3D environment using the sim3d.Actor
object. Add the box actor to the world.
box = sim3d.Actor(ActorName='Box'); createShape(box,'box',[0.5 0.25 0.25]); box.Color = [1 0 0]; add(world,box);
Create multiple custom views using the createViewpoint
function.
view1 = createViewpoint( ... world,Name='Front',Translation=[-4 0 0]); view2 = createViewpoint( ... world,Name='Right',Translation=[0 4 0],Rotation=[0 0 -pi/2]); view3 = createViewpoint( ... world,Name='Back',Translation=[4 0 0],Rotation=[0 0 pi]); view4 = createViewpoint( ... world,Name='Left',Translation=[0 -4 0],Rotation=[0 0 pi/2]);
Using the UserData
property of the sim3d.World
object, create a user data structure with a field named Step
to store the simulation step during simulation.
world.UserData.Step = 1;
Run the simulation. The viewer displays the default view.
sampletime = 0.01; stoptime = 10; run(world,sampletime,stoptime);
Output Function
Use the output function to set the view in the Simulation 3D Viewer window at a specific simulation step. The Front
and Back
views display a square. The Right
and Left
views display a rectangle.
function outputImpl(world) if world.UserData.Step == 200 setView(world,world.Viewpoints.Front); elseif world.UserData.Step == 400 setView(world,world.Viewpoints.Right); elseif world.UserData.Step == 600 setView(world,world.Viewpoints.Back); elseif world.UserData.Step == 800 setView(world,world.Viewpoints.Left); end world.UserData.Step = world.UserData.Step + 1; end
Input Arguments
World object that defines the 3D environment, specified as a sim3d.World
object.
Example: world = sim3d.World()
Viewpoint object that defines the viewpoint created using the createViewpoint
function, specified as a Viewpoint
object. The Viewpoint
object is stored as a field in the viewpoint
structure. You can use the Viewpoints
property of the sim3d.World
class to access the Viewpoint
object. You can also modify the aspects
of the viewpoint object by setting values for the Name
,
Translation
, and Rotation
properties.
Example: viewpoint = View1
