_ devexit dm9000_drv_remove (struct platform_device * pdev) Similar to the previous remove function, they politely return the resources they occupy to the kernel. Imagine if each module is not so polite, if a system runs for a long time and the system resources are always exhausted, then the only thing that waits for us will crash. Therefore, courtesy not only "survive" in our daily lives, but also shows this excellent character in Linux systems! The content of this article is relatively simp

1. Create a texture imageOpenGL requires that the texture height and width must both be the Npower of 2. This texture image is valid only when this condition is met. Once the pixel value is obtained, we can pass the data to OpenGL to generate a texture map for OpenGL:Glgentextures (1, @ texture );Glbindtexture (gl_text

Introduction to the development framework see: One of Opengl ES NDK Instance development: building a development frameworkThis chapter draws a rotated texture pyramid based on the sixth chapter (six: Texture mapping) of the Opengl ES 1.x NDK instance development, with the same principle as texture mapping, and it is important to note that the vertex arrays and te

Forwarding, please keep address: http://blog.csdn.net/stalendp/article/details/50953869Recently in summing up OpenGL knowledge, thought of previously searched for DOTA2 related articles: "Dota2-character Shader Masks Guide", and DOTA2 model can also be downloaded on the Internet, so it is well worth to be used as a summary of light-related knowledge. I use the ogre model to do the experiment, the effect is as follows:This shader just to summarize shad

) { glActiveTexture(TextureUnit); glBindTexture(GL_TEXTURE_2D, m_shadowMap); } We will switch between the shadow map and the default framebuffer. The first output is shadow map and the second output is framebuffer. The above two functions are used to execute this function. The following is the code for Vs and FS (PS) during shadow map rendering during the first rendering: Shadowmap. # Version 400Layout (location = 0) in vec3 position;Layout (location = 1
