This chapter is mainly about the texture of the further explanation, we often need to put the real picture in the Web page rather than to create a picture, through the texture we can be rasterized graphics and image texture to form a map and the picture in the graphic display. The basic process is consistent with the previous chapters, in the shader is mainly added a sampler of the variable function is to remove the graphics from the texture unit on the different coordinates of the element displ

Webgl -- start to make some real 3D objects Original article of Lesson 4: Http://learningwebgl.com/blog? P = 370 Case study: http://learningwebgl.com/lessons/lesson04/index.html The difference between the code in this lesson and the previous one is completely concentrated in the animate, initbuffers and drawscene features. If you scroll down to animate, you will see some very small changes: variables, remember that the two objects in the current

The threshold for using 3D technology in H5 is lower, based on WebGL (THREEJS), a subset of OpenGL's browsers, supporting most of the major 3D function interfaces. Currently the mainstream browser has better support, IE needs 11. Recently, the development of Web 3D computer room has been over, there is time to organize some of the results of this period. Mainly involves the use of H5, JS, WebGL technology.G

Because of the collection software of Beijing street view in the early stage, there were a lot of street view pictures in the hand; and The Amazing effects of google Street View and soso street view gave rise to the idea of a small test, why don't I turn the image into a 3D street view and put it online. So I began to collect relevant information. After five days of trial, I finally achieved initial results; First of all, thanks to http://www.hiwebgl.com /? P = 42

In WebGL, the opengl-es-2.0 API is called, and the opengl-es is designed for embedded devices, which, like other devices, use GLSL (GL shading Language) to write fragment programs and execute on the GPU shader. To complete rendering of the object. GLSL plays a very important role in it, so to play good webgl, we have to understand GLSL, this article mainly introduces the basic use of shader and composition.

Recently in touch with the unity of the WebGL platform, in fact, this platform as a substitute for Web player, has been able to meet most of the development needs, and do not need additional plug-in support, it is indeed convenient, but still encountered a lot of problems in development, here to record and share the solution.The first is the build option, in "Player Settings".Resolution and presentation and old Web Player don't change, you can put you
