Texturematerial (texture: texture2dbase = NULL, smooth: Boolean = true, repeat: Boolean = false, mipmap: Boolean = true) // texture, smooth, repeated, enable mipmap texture creates a new texturematerial. 1. Texture A commonly used technology in 3D computer graphics Paster rendering is calledMipmapping. To speed up rend

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.

This lesson will teach you how to use three different texture filtering methods. It also teaches you how to use a keyboard to move objects in a scenario and how to use simple light in an OpenGL scenario. This course contains a lot of content. If you have any questions about the previous course, first review it. Before entering the code below, it is very important to have a good understanding of the basic knowledge.We still modify the code in Lesson 1.

I. Introduction to Texture projection ing Projection texture ing is used to map a texture to an object, just like projection a slide onto a wall. Projection texture ing is often used in some shadow algorithms and volume rendering algorithms. Strictly speaking, the projection textur
