ES system Encapsulation Tutorial Premium Advanced Edition, provides my own package of Wind7 x86x64 and XP three versions of the system download. This tutorial is not for people without foundation, and to learn from scratch, I recommend a few basic tutorials.1.

This paper mainly discusses the algorithm to extend the line into 2d line surface.It's easy to extend the P0P1 line into a polygon.vec2f line = P1-p0vec2f normal = vec2f (-line.y, line.x). Normalized () .vec2f A = p0-thickness * normal;vec2f B = p0 + thickness * normal;vec2f c = p1-thickness * normal;vec2f d = p1 + thickness * normal;If this is a straight line, but if there is a polyline, we also need to calculate the intersection point whereFirst we'll find out tvec2fT= ((P2-P1). Normalized ()

shader is the same as the vertex shader defined earlier. But this time we're going to pass a uniform, called U_color. It is not like a property, each vertex is set to one; a uniform will let each vertex use the same value unless we change it at the same time. The U_color is also a four-component vector, as is the position used by the location in the fixed-point shader, but in the context of the color, the four components correspond to red, green, blue, and Alpha.We then define main (), which is

This example describes how to use a transparent background to draw OpenGL images. The procedure is as follows:1. Use transparent theme for ActivityAndroid: label = "Graphics/OpenGL ES/Translucent GLSurfaceView"Android: theme = "@ style/Theme. Translucent"Android: configChanges = "keyboardHidden | orientation | screenLayout | screenSize | smallestScreenSize">2. In the 8888 (RGBA) format, the Alpha channel is required to display transparent images.[Java

glbindtexture (gl_texture_2d, _textureid);Specifies the value of the uniform variable for the current program object, and Parameter 1 represents the new value used (Gl_texture1) gluniform1i (_textureslot, 1);Draws a texture in the specified area.Note: The coordinate representation used to represent the texture range differs from the Uikit and OpenGL coordinates, ranging from (0,0) left down to (top) right.Texture Usage Range vertexConst Glfloat texcoords[] = { 0, 0,//lower left 1,

Surfaceview's black background blocks the parent's background, and now sets the surfaceview background to be transparent, seeing both the 3D object being painted and the background.In onsurfacecreated, call Gles20.glclearcolor (0f, 0f, 0f, 0f); Alpha is 0, which is transparent.Then, the Surfaceview must be treated as follows:Mglsurfaceview.seteglconfigchooser (8, 8, 8, 8, 16, 0);Testrenderer renderer = new Testrenderer ();Mglsurfaceview.setrender (renderer);Mglsurfaceview.getholder ().

The code for a chunk write to the file is as follows:By observing the flush function, we find that the Fdt file is very simple to write, with two lines of code:The previous line of code records the entire chunk in docbase (minimum docid), Numbuffereddocs (Doc number), Numstoredfields (Number of field per Doc), lengths (length per Doc), There are four kinds of information
