built into WebGL, and the value needs to be turned on.How to achieve a hybrid?1. Turn on the blending function: Gl.enable (GL. BLEND).2. Specify the Blending function: Gl.blendfunc (GL. Src_alpha, GL. One_minus_src_alpha).If we only set the fourth component of the color, and the transparency effect is not visible, you must perform the above two steps.6.gl.blendf

shares the same Android Surface with other views in the window. Therefore, WebView responds to the onDraw event on the UI thread, starts the page rendering pipeline, and draws the new frame content to the Canvas through onDraw; WebView uses SynchronousCompositor to synthesize page content. "synchronization" refers to running on the UI thread, and merging is triggered by the onDraw event of the UI thread, instead of being triggered by VSYNC. From the thread-based synthesizer perspective, the

OpenGL Development Environment Configuration Luo chaohui (http://www.cnblogs.com/kesalin) This article follows the "signature-non-commercial use-consistency" creation public agreement OpenGL has some reusable auxiliary libraries, such as glut, Glee, and glew. You need to install them on your own on the Windows platform, because Microsoft wants to promote its DX, only OpenGL 1.1 is supported in windows. You can open \ Microsoft Visual Studio X.

Cocos2d involves four coordinate systems: GL Coordinate SystemCocos2D uses OpenglES as the graphics library, so it uses the OpenglES coordinate system. The GL coordinate system origin is in the lower left corner of the screen,X axis to the right, Y axis to the up. Screen Coordinate SystemApple's Quarze2D uses different coordinate systems, with the origin in the upper left corner of the screen,X axi

(Draft only, not sorted) 2.5 GL error message GL can only detect part of the error conditions. This is because in many error detection cases, it will adversely affect the error-free program. Command for getting error information: Enum geterror (void ); Each detected error is assigned a numerical code. When an error occurs, an identifier is set and the encoding is recorded. If another error occurs, the enco
