x3d examples

In this lecture, we will describe how to create and construct a dot, a line, and its basic 2D graphics, and briefly introduce the X3d coordinate system. Coordinates of a point and a point You need to have clear coordinates for setting objects in a x3d scene. In the same scene, there is a unified coordinate system. This coordinate system is a right-handed coordinate system, at the beginning (that is, the o

In the x3d scene space, X3D provides the point of view node viewpoint in order to enable the viewer to conveniently control the position and angle of observation. At the same time, in order to be able to browse in different ways, X3D provides the Navigationinfo navigation node. Here is a description of the use of these two nodes. One, Viewpoint node The Viewpo

The first lecture X3d Overview and installation configuration This lecture focuses on X3d's overview, the X3d Editor, and its installation configuration. I. Overview of X3D The term "web3d" derives from the Web3D Alliance (web3d Consortium (W3DC)), formerly the VRML Alliance. The organization has put forward VRML1.0, VRML2.0 and VRML97 specifications. The VRML

Seventh lecture light Source processing In the x3d scene space, the illumination brightness of the Shape object can be treated by point Light node (pointlight), Parallel source node (directionallight) and concentrating light source node (SpotLight). This explains the properties of these three nodes and how to use them. One, point Light source node (pointlight) Pointlight is a point light that emits light in all directions. Light illuminates all ge

We know that for Visual C + +, the implementation of the interaction is done through a message map. Similarly, X3D's interactive implementation is also through a similar mapping mechanism. The generation of user events is generated by the corresponding sensor, and the route statement is the equivalent of an event mapping, which is mapped to another input event. In the X3D, the user event sensors are: keysensor (keyboard sensor), Stringsensor (string

Display of the second lecture text In this lecture, we will describe how to create a scene effect with text, and in the process of creating a detailed description of how to set the light source and text style. First, create a new X3d file The operation is as follows: 1. Run X3d-edit, and appear as shown in the image of the interface. Description X3d-edit

X3D support for multimedia is achieved through these three nodes: AudioClip (audio data node), Sound (Audio playback node), and movietexture (Image texture node). In this lecture, let's briefly introduce the properties of these three nodes, and then give some examples to illustrate the use of these nodes and the playback of audio and video. One, audio and video nodes 1, AudioClip (audio data) node Audio

Eighth Talk Texture mapping In the previous lecture, we used material nodes to change the appearance of the object. These properties are only the macroscopic effects of consistency, and we have not yet touched upon some of the details of the object. Texture mapping and processing can enhance the expressive force for the surface details of an object. This lecture is divided into three parts to discuss: First, the use of X3D basic texture nodes, the se

In X3d, the script is embedded by using a programmatic node script. It supports Ecmascript/javascript or the Java language. Here's an explanation of what a ecmascript,ecmascript is also a scripting language, developed using Netscape and Microsoft, and is an object-oriented language, ECMAScript and Dom are very close to the current implementation of JavaScript and JScript, although they are used in a network environment, but they can be used in any scr

In the x3d scene space, each shape has its own space coordinate, which can be moved, rotated and scaled in the scene space by modifying the space coordinate system. X3D provides a geometric transformation of the transform node for modelling, the main attributes of which are shown in the following table: properties meaning default value use instructions translat

How does one automatically roam or walk in a specified path in the VRML/X3D environment? And if the control only goes through? I checked a lot of information today and concluded that this is a relatively simple solution. It mainly uses timesensor, touchsensor, positioninterpolator, and orientationinterpolator. Example: Def PI positioninterpolator { Key [0 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 ] KeyValue [ 9 1.5 2, 9 1.5 4, 20 1.5 15, 22 1.5 15, 23 1.5

X3D provides basic 3D modeling nodes such as cubes (Box), cylindrical (Cylinder), Cone (Cone), Sphere (Sphere). In this lecture, let's briefly introduce the use of these nodes, and then introduce the node's grouping and how the nodes are reused. One, Cube box The code is constructed as follows: Description: The main property of the box node is size, which determines the length (x direction), Height (y direction), and width (z) orientation. This i

Dynamic Planning and two examples, planning two examples Now we need to clarify these common algorithms, or else we can only be a low-level programmer. Dynamic Programming (DP) is the optimal mathematical method for solving the decision-making process. Dynamic Planning is generally divided into linear motion gauge, regional motion gauge, tree motion gauge, and backpack motion gauge. Dynamic Planning is a m
