#Draw sprite coppercube code#This code adds a second scene node to the scene, a built-in scene node named BillboardSceneNode. Scene.getRootSceneNode().addChild(billboard) Var billboard = new C元D.BillboardSceneNode() īillboard.getMaterial(0).Tex1 = engine.getTextureManager().getTexture("actionsign.jpg", true) īillboard.getMaterial(0).Type = C元D.Material.EMT_TRANSPARENT_ADD_COLOR add a transparent billboard scene node with a text sign Lets go on in the code and see what it is doing next: We'll implement the scene node later and explain everything in detail then. In the code above, we only added your scene node to the scene graph. SceneNodes in CopperLicht do have a lot of properties, like materials and have the possibility to be animated, so, by creating your own SceneNode, you can drawģd stuff using your own technique and take advantage of all the features of CopperCube like transparent sorting, animators and similar without the need to think about this. The camera from which the 3d scene is drawn. Another scene node type is for example the CameraSceneNode representing Scene nodes can draw different things in CopperLicht, the most common thing is probably the MeshSceneNode, which drawsĪ chunk of 3d geometry, for example an imported 3D Studio. If the car scene node is made invisible, also all child scene nodes like the person in that car is then invisible as well and need not To move, all children in it are moved as well. And that car might have a child which is a person, driving in the car. This city-SceneNode might have a child, for example a car. For example there might be a city, represented by a scene node. Everything in the graph is a node which might have children. So, what is a scene node at all? And why should you want to create your own?ĬopperLicht renders the 3d graphics using a scene graph. This is where we add our own scene node to the 3d scene. Mynode.addAnimator(new C元D.AnimatorRotation(new C元D.Vect3d(0, 0.6, 0.8))) Scene.getRootSceneNode().addChild(mynode) The next piece of code should be more interesting: Here, the 3d engine is initialized for the canvas with the id '3darea' and a 3d scene is created, with a blue background color. tBackgroundColor(C元D.createColor(1, 0, 0, 64)) Return // this browser doesn't support WebGL // add a new 3d scene Var engine = new C元D.CopperLicht('3darea') The first few lines should be quite self explaining: jpg files named test.jpg and actionsign.jpg which are used in this example as textures. html file and paste this code into there, place the copperlicht.js file from the CopperLicht SDK in the same directory, andĪdd two. #Draw sprite coppercube how to#Tutorial 03: Showing how to create your own scene node.Ĭreate a. #Draw sprite coppercube full#The following is the full code of this example. In contrast to the other tutorials, we don't need the 3d editor CopperCube at all, everything we are doing here is writing code. A very simple 3d scene node, below a 3d billboard.
