Implement geometry instancing in OpenGL

is of course the view matrix ). The rest of the main function creates a simple vertex-by-vertex diffuse illumination, which is the same as the work done by the fixed function pipeline. Do not scale the Matrix to avoid the problem of converting the normal to the world space. If you want this method to work normally in all circumstances, you need to calculate a normalized matrix for each instance and upload it to the shader. Performance Performance Evaluation In the following disince we compare t

. Changes and randomness are equally important-changes in behavior, and a certain degree of unpredictability within the scope of trust. " Game Rules and natural gamesIn all our descriptions about AI, we use FPS. There are more than one kind of AI. What we have described is processing a set of rules in the 3D world. AI is far more than that. Often the best AI is actually very simple. It is a set of rules that players must respond to and process respons

Game Engine analysis (I)

hardware uses polygon (triangles) of three vertices ). The next generation of nvidia and ATI graphics cards allow you to render in mathematical form (known as high-order surfaces), but since this is not the standard for all graphics cards, you cannot rely on it as a rendering strategy. From a computing point of view, this is usually expensive, but it is often the basis of new experimental technologies, such as surface rendering or softening of sharp edges of objects. We will further introduce t

an image with the correct order of coverage. Now that we have Z-buffer, I have to overturn this theory. We have to first rendera and then renderb. Why? Because when you rendera renderb again, DirectX will judge by itself that there is already a in some places, so B does not need to draw anything in those places and skip it directly, what if it is a big image of two full screens? How much FPS is saved? This method is called the reverse painter algorit

Is gaming performance better on Linux than on windows?

that of the Windows platform. Phoronix reported that in a set of i7-3930K processor + GTX 680 graphics card platform, win7 SP System Using d3d rendering "Left 4 dead 2" game has FPS, however, in Linux, OpenGL rendering is 17% FPS, and the performance is higher. In Windows, OpenGL rendering is only FPS. In short, the Game Performance in Linux is better. This is o

Toshiba released a 1080p @ 60fps Image Sensor

PRNewswire: Toshiba released a new chip for the security/monitoring and automotive markets. It has a full-HD (1080 p) CMOS image sensor with a frame rate of 60 FPS, the pixel size is 2.7um and has a dynamic range of DB. It can achieve color noise reduction (CNR) Under Low Illumination ). The target market for the 1st/3 inch sensors of tcm3167pl is security/surveillance cameras and automotive systems. Toshiba achieves single screen, staggered lines,

Go Shadow Map & Shadow Volume

Transferred from: http://blog.csdn.net/hippig/article/details/7858574The term shadow volume is almost an object that the FPS player and graphics enthusiast talk about with the release of DOOM3. Although the game is not yet available, we still have reason to think it will be one of the hottest FPS games of the 2004, thanks to John Carmack's legendary experience and some surprising previews of DOOM3 's releas

U3d Vertical Synchronization

Unity3d a new scene is empty, the frame rate (FPS is always very low), probably between 60~70. Have not quite understood what is going on, now basically understand. I am here to explain why, if there is a mistake, please correct me. In Unity3d when the runtime opens the profiler, we see that VSync is a big part of this. What is this, this is vertical synchronization, to explain later. We can turn off vsync to increase the frame rate, select Edit->proj
