The name 1994 VRML was first formally put forward at the first WWW conference held in Geneva in March. The draft standardization of 1994 10 VRML 1.0 was published at the second WWW conference held in Chicago.
The first edition of 1996 VRML 2.0 was released and passed at the excellent 3D graphics technology conference -Siggraph'96 held in New Orleans in August. On the basis of VRML 1.0, it is greatly supplemented and improved. It is based on SGI's mobile world, a dynamic field.
1February 1997, VRML was officially released as an international standard.1October,1998,65438 was officially approved as VRML97 by the International Organization for Standardization (ISO). VRML97 is only slightly modified on the basis of VRML2.0.
The VRML specification supports texture mapping, panoramic background, fog, video, audio, object motion and collision detection-everything used to build a virtual world. However, VRML has not been widely used as expected, but it is not VRML's fault. You know, in those days, 14.4k modems were very common. VRML is almost uncompressed script code, plus huge texture maps and other data, which was a nightmare to transmit on the Internet at that time.
Present situation of domestic WEB3D software:
WebMax
Developed by Shanghai Chuangtu Network Technology Development Co., Ltd., it is the first patented WEB3D invention software in China and the only WEB3D technology designated by Shanghai World Expo 20 10. Its greatest feature lies in its compression ratio, which can reach 120: 1. Therefore, the finished file is small in size, has a natural advantage in network publishing, and has a delicate picture. In the aspect of interaction, it needs to cooperate with certain coding ability and has strong expansibility. Moreover, the configuration requirements for client machines are very low, so you don't have to worry too much about the loss of browsing groups. At present, the software is updated to version 2.0, although it is relatively 65438+. WEBMAX3.0 will be released in June, 20 10, which has made great contributions in visual effects, operation panel, interactive functions, design and development, and can be compared with foreign advanced technologies. And still adhere to the concept of free. However, with the concept of free software forever, WebMax has a large number of fans in China, and the number of users has reached 654.38 million+people. Subsequent versions are also constantly introducing new functions and effects (water special effects+real-time reflection+global halo, etc.). ) will also be released one after another, which is worth looking forward to.
Fulpi
In fact; It can be said that it is an online version of stand-alone virtual software VRP with a large number of users in China. Therefore; It is also named VRPIE. Software can be divided into * * * exclusive version and official version; The exclusive edition of * * * provides complete functions; However, it does not provide the function of saving the project. With a large number of original stand-alone software users, the launch of VRPIE immediately caused great repercussions in the industry, and a number of frequently appearing commercial works benefited from the absolute advantage of the number of stand-alone users. VRPIE software has a good degree of humanization, and the software has a high capability maturity model, which can be used quickly. Some simple interactions can be completed without programming, and the software also provides a programming interface, which can realize more complex interactions through programming. In addition, the physical engine system that appeared later realized the effects of rigid body collision and control, physical flame, physical fluid and so on, which greatly improved the software. It can be said that VRPIE is a mature virtual reality development tool based on strong technical backing, which will definitely have a positive impact on the development of China's virtual reality industry.
Transform 3D
It appeared at the latest among the three popular softwares, which may be the reason why the software was upgraded to Dx9' s API graphical interface as soon as it started. In addition, the free version of this software is limited by the number of models, and even the annoying official logo is gone. All this adds a lot of mystery to Converse3D, and everyone is full of expectations for his graphic performance, although this expectation has been greatly improved in addition to simulating the effect of water. But the performance of the overall picture is not as successful as everyone expected. Nevertheless, we still believe that Converse3D still has the ability to achieve greater breakthroughs by virtue of its leading position in API interface! Of course, it is worth mentioning that Converse3D's development team first put forward the concept of "one scene, one community" in line with the development trend of the network, and led the industry to develop the online multi-person interactive communication function of Web3D, which opened up a broad imagination space for the development of Converse3D, and even created a brand-new model for the popular SNS community concept in the interactive form, which is a bright spot. Because the software does not support programming interface for the time being, it has many functions on the interface, so it can be more humanized in design and improved in network publishing function! 1998.VRML organization changed its name to Web3D organization, and formulated a new standard, which can extend 3D (X3D). By the spring of 2000, Web3D had completed the transformation from VRML to X3D. X3D integrates advanced technologies such as XML, JAVA and streaming technology, including more powerful and efficient 3D computing power, rendering quality and transmission speed.
At the same time, a competition in Web3D format is going on. Adobe Atmosphere is a professional development solution for creating a virtual three-dimensional network environment, and Macromedia Director 8.5 Shock Wave Studio. Although there are so many solutions, has everyone jumped on the train of Web3D? Some difficulties and obstacles still exist. The first is that there is no uniform standard. Each scheme uses a different format and method. Flash is popular today because it is unique, and JAVA is used on all platforms because it is unique. Without standards, it will be very difficult to realize 3D on the Internet. In addition, the plug-in problem is also a dilemma. The standards developed by almost every manufacturer need the support of their own plug-ins, ranging from several hundred K to several megabytes, which inevitably limits the enthusiasm of some people when the bandwidth is not satisfactory.
