WebGL on main thread As before. Developing a WebGL application, the only approach is put all the stuff at the main thread. But it would definitely bring some limitations for the performance. As the above picture shows, in a 3D game, it might need to do lots of stuff in a update frame. For example, updating the transformation of 3D objects, visibility culling, AI, network, and physics, etc. Then, we finally can hand over it to the render process for executing WebGL functions. If we expect it could done all things in the V-Sync time (16 ms), it would be a challenge for developers. Therefore, people look forward if there is another way to share the performance bottleneck to other threads. WebGL on worker thread is happened under this situation. But, please don't consider anything put into WebWorker would resolve your problems totally. It will bring us some new challenge as well. Following, I would like to tell you how to use WebGL on worker to increase the performance and giv...

A-Frame is a WebVR framework for developers to make their VR content rapidly. It is based on Entity-Component system. So, it could bring us flexibility and usability for developing. This is my slide for the sharing in WebGL Meetup Taipei #03. Introduction to A-Frame from Daosheng Mu

We all know VR is a very popular stuff currently. There are lots of big companies start to develop their own headsets. Facebook and Youtube begin to support 360 degree videos on their platforms. Due to their works, we could expect there would be huge amounts of applications that target to Virtual Reality in the next couple of years. Currently, if you want to play VR content, you have to spend about $300 USD to buy a headset and plug several wires into your desktop. I think it would increase the wall to invite users to use VR. On the other hand, Google and Gear VR choose to use mobile devices as their headsets. You just need to spend $20 USD to buy a Google Cardboard and can start to enjoy the interaction with VR content. How about the content part of VR applications? If you want to write an application for Oculus, you must write Windows version for Windows users, or MacOS version for MacOS users. On mobile devices, you also need to rewrite apps for Android and iOS versions. No one ...

   Nowadays, if people would like to implement a Web3D demo, most of them would use WebGL approach. WebGL seems to be the spec of Web3D,  because Chrome, Firefox, Safari, IE, and Android Chrome have supported it. iOS 8 will be launched this year, and WebGL also can be executed on iOS 8 Safari. In order to support iOS 7 pervious version for Web3D, I survey the Software Renderer method of three.js and help them add texture mapping and pixel lighting. First, we get the image data from canvas. var context = canvas.getContext( '2d', { alpha: parameters.alpha === true } ); imagedata = context.getImageData( 0, 0, canvasWidth, canvasHeight ); data = imagedata.data; Second, we have to project the faces of objects to the screen space, we needn't sort them by painter algorithm, because three.js has implemented a screen size z buffer to store the depth values for depth testing. And then, start to interpolate the pixels of these faces. var dz12 = z1 - ...

Arca3D is a platform can let you store your 3D models. There is a more interesting thing, it also can help you print your models.  First, select a model you uploaded.   Next, click the button, Download STL File Then, you can check it through STL viewer Finally, pick the *.stl file to your 3D printer and get your great physical 3D model. Enjoy it: http://dev.arca3d.com
