As one would expect, augmented reality and virtual reality have become one of the highlights of this F8 conference. Xiao Bian has just reported on Facebook Spaces and ARstudio, but Facebook will announce more news in succession. Now, Oculus has launched React VR to help developers quickly build an immersive experience for VR.
To use React VR content, creators need to have knowledge of JavaScript so that they can build and deploy VR experiences using standard web tools. React VR also supports a variety of APIs (such as WebGL and WebVR), allowing heads to be connected to scenes in web pages.
The software allows users to create content in 3D scenes through React components. 360-degree panoramas, 2D UI, text, and images can all be combined with audio and video.
Oculus has developed experiences for multiple partners through ReactVR, including:
Dubai Dubai’s “Discover Dubaiâ€: A treasure hunt game that encourages users to explore Dubai 360 degrees.
· USA Today's “Buffalo Trace Distilleryâ€: Let the audience visit the oldest wineries in the United States.
· The British Museum has developed an exclusive museum tour experience that allows users to use their hands to play various virtual exhibits.
·The New York Times is still deepening VR news, exploring the Antarctic ice sheet with stunning 360-degree pictures and videos.
· Airbnb developed an Airbone prototype experience in just a few weeks, demonstrating the flexibility and power of React VR.
The first process of Investment Casting production is the manufacture of investment mold, investment mold is used to form the cavity in the refractory shell model, so in order to obtain the casting with high dimensional accuracy and surface finish, the investment mold itself should have high dimensional accuracy and surface finish. In addition, the performance of the melt itself should also make the subsequent shell making process as simple as possible. In order to obtain the above high quality requirements of the investment die, in addition to good pressure (pressing the investment die), but also must choose the appropriate mold material (referred to as the mold) and reasonable mold making process.
The advantage of the investment casting method is that it can cast complex castings of various alloys, especially high temperature alloy castings. For example, the blade of jet engine, its streamlined outer profile and cooling inner cavity, with machining process almost impossible to form. Investment casting process can not only achieve mass production, ensure the consistency of castings, but also avoid the stress concentration of residual blade lines after machining.
The biggest advantage of investment casting is that because investment casting has a very high dimensional accuracy and surface finish, so it can reduce the machining work, just leave a little machining allowance in the parts requiring higher parts, and even some castings only leave grinding and polishing allowance, without mechanical processing can be used. It can be seen that the investment casting method can greatly save machine tools, processing time and metal raw materials.
