By ho minggui (http://blog.csdn.net/hmg25)Reprinted please indicate the source The previous examples are solid 3D models. Today, we began to attach the gorgeous textures to these models to make them look closer to the real objects we remember. Function startup To use textures, we need to turn on some OpenGL switches to start some of the features we need: gl.glEnable(GL10.GL_TEXTURE_2D); . This call is indispensable. If you do not enable this function, you cannot map the image to a polygon.

and the projection coordinate transformation matrix are multiplied and saved in advance. After the model coordinate transformation matrix is ready, it is multiplied by the previous results, passed to the uniform, and then drawn.Let's take a look at the actual code. > Some code in script. js // Generate and initialize various matrices. var mMatrix = m. identity (m. create (); var vMatrix = m. identity (m. create (); var pMatrix = m. identity (m. create (); var tmpMatrix = m. identity (m. create

Renderer is an interface dedicated to 3D rendering. To inherit from it, we need to overload the following methods: Public void ondrawframe (gl10

. This is the difference from the previous lesson. Easy! But because we need to make more colors here and the triangle vertices also become more, we need to use initbuffers to process more vertices and colors. Therefore, apart from the above changes, we also need to add the following code in the buffer to adapt to changes: Gl. bindbuffer (GL. array_buffer, pyramidvertexpositionbuffer );

shader and assign the color of the Texel to the element. 3.gl.createtexture () Create a texture object to store the texture image. 4.gl.deletetexture () Use Textur to delete a texture object. If you delete a texture object that has been deleted, no error will be made and no effect will occur. 5.gl.pixelstorei (pname, param) Handles the loaded image in the way specified by PName and Param. Parameters PName: Can be one of the following. Gl. UNPACK_FLIP

coordinate system. The general OpenGL program is the standard Cartesian coordinate system, that is, the lower left corner is the origin, X is horizontally right, and Y is vertically extended. Like the famous cocos2d engine, this method is used. I prefer another method of describing the origin in the upper left corner, so this set of coordinate system is used: The Renderer of glsurfaceview provides three interfaces: drawing when the size is changed during creation. The operations we take in the
