prototype/base class of other lighting objects and inherits from the Object3D object/type. It has only one Color attribute of the THREE. color type, that is, Color.
In Three. js, as an Object3D object, illumination is added to the Scene through the Scene. add () method, and the Renderer automatically renders the added illumination effect.

The Code is as follows:
THREE. AmbientLight = function (hex ){THREE. Light. call (this, hex );};

Processing supports object-oriented programming.
However, processing is not like the prefuse that we will introduce below. It has already integrated layout algorithms.

another kind of object--points.Points is actually a collection of points that have been called particlesystem (particle system) for a long time and renamed points when the R68 version was renamed POINTCLOUD,R72. Renaming is mainly because, mr.doob, a particle system should be a complete system of handling particles and related physical properties, while the points in three is much simpler. So ultimately this class is named points.The typical effect that points can achieve is this: official exam

You use lighting to illuminate scenes and objects to create a perfect visual atmosphere. Lights can be used to simulate the sun, burning matches, flashlights, gun flares, or explosions, and so on

There are 3 main types of light sources in Direct3D, which we call the three major light sources: Point light, directional (directional light) and spotlight.
In Direct3D 9.0c, when it comes to the light source, we must talk about a structure, that is,
to the following rules:
A light source that is set to be unimportant (not Important) is calculated in the form of a vertex or spherical harmony
Brightest directional light is a pixel light source
Render mode is set important (Important) light source is the pixel light source
If the number of pixel light sources based on the above rules is less than the number of pixel lights in the quality setting (Pixel light count), more light
3.3 LightThere are all kinds of lights in the theater, and the same in three-dimensional rendering scene, there can be more than one light. Lighting and cameras are a must-have for three-dimensional rendering scenarios, and if not specified (like the 3.1.1_rendercylinder example, we don't assign cameras and lighting to renderer), Vtkrenderer automatically creates default lighting and cameras. VTK uses class Vtklight to represent the lighting in the rendered scene. Similar to real-world lighting,

Pay attention to a question about deltatime. The code in the update () function is executed by frame.If we need to move an object in seconds, we need to multiply the return value of the Input. getaxis () function by time. deltatime:
var speed = 5;function Update(){var x = Input.GetAxis("Horizontal")*Time.deltaTime*speed;var y = Input.GetAxis("Vertical")*Time.deltaTime*speed;transform.Translate(x, y, 0);}

Object3d is the basic class of all 3D objects and the simplest 3D object. It defines the basic attributes and methods of a 3D object.Object3d can be used as a container to contain other 3D objects, similarDisplayobjectcontainer.
All 3D objects are inherited from object3d. 3D objects can be divided into visual objects and non-visual objects in general:Non-Visual Object● Camera3d (3D camera)● Light3d (3D lighting)● Ambientlight (ambient light)● Directionallight (
