Brute Force not very userful for nowadays game, due to its poor fps. I'm a novice for terrain rendering, maybe the "levels" cocould increase the fps.
How to do: Here is the principle and below is the code (yes, I use Ogre O >_

Because the project needs to use Flash to develop 3D animation, it reminds me of the several popular Flash 3D libraries that I never knew where to find PV3D and Away3D, it is said that PV3D has high performance but is not flexible. Away3D is flexible but has low performance. Performance is indeed a very important factor to consider, the performance of the two is poor, there is no ready-to-use answer on the Internet, so you can do it yourself. It took some time to run the successful PV3D and Away

Generally, rAF is called 60 times per second, that is, 1000/60. The trigger frequency is about 16.7 ms. (When performing complex operations, when it finds that it cannot maintain the 60 FPS frequency, it will reduce the frequency to 30 FPS to maintain the stability of the number of frames .)
In short, using requestAnimationFrame to trigger a rolling event is equivalent to the above:

Based on the code in the previous tutorial, we added a timerclass class. The function of this class is very simple, that is, it can calculate the time difference between two adjacent frames. This time difference can be used to achieve smooth animation, so that the animation will not be different from the FPs of different machines, so that the animation effect becomes faster or slower.
We mainly use the queryperformancecounter function to query the cou
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.

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
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?
