Recently, I have been dealing with C # stuff. I haven't written C ++ code for a long time. I'm afraid that my hands will forget it. I plan to write c ++ code. What should I do? I want to come and think about it. I have been familiar with OpenGL in my previous work, so let me learn about d3d. I thought there would be a lot of Chinese entry-level documents for d3d, and I didn't find any suitable documents aft
Today is the first time I open my website here. I will first explain that writing this document is not a tutorial. I am not an expert either. I just want to have a deeper understanding of direct3d, at the same time, if you see these things unfortunately, I hope it will be helpful to you. At the same time, I solemnly declare that this post will not be reprinted. I am not an expert and it is inevitable to make mistakes. However, if someone else is misled, it is a big mistake. I hope you will forg

Finally, I have finished talking about the basic concept of space ry in the first three articles. Now I can say something practical. For a long time, I have always hoped to record some of my 3D knowledge in the most easy-to-understand language as a series of popular science articles for everyone to take a look. About a decade ago, I had my first computer and soon saw the charm of 3D games. After hearing about OpenGL, I heard about Microsoft's DirectX 3D (d3
Original post address: http://blog.csdn.net/popy007/article/details/4091967 In the previous article, we discussed the principle of Perspective Projection Transformation and analyzed the method for generating the Perspective Projection Matrix used by OpenGL. As we said, different graphic APIs cause matrix differences due to differences in the left-right coordinate system, vector column vector matrix, and transformation range. There can be dozens of different perspective projection matrices, howe
Before going to bed, I decided to update the second article in the series "RPG production notebook". I wrote RPG for the first time and encountered many problems. Most of the problems were caused by reading previous articles online, the problem can be solved. Think about it carefully. If the predecessors do not write it, we will not be able to learn this knowledge. Therefore, Yu Gong and Yu Gong must complete this series of articles. In the second article, there are many ways to render devices a
To learn about d3d, we should understand the three memories. We collected relevant information online and collected it. Three types of memory (non-local memory), memory (local memory), and system memory, among which we all know that the system memory is our memory. What kind of memory is this? In fact, it was because the memory of the video card was very small in the past. At that time, when the memory size was 16 MB and 32 MB was the mainstream, if y
Note: Subsequent d3d explanations are based on C ++. Before explaining d3d initialization, we will introduce several pilot concepts.1. The d3d SDK provides developers with two device types: reference device or ref and hardware abstract layer or Hal ).The difference between the two devices is that ref performs 3D computation by means of software simulation, and a
Author: Nang Lanhai (Http://blog.csdn.net/you_lan_hai) The difference between DirectX 3D and OpenGL coordinate system brings us a lot of trouble and makes the novice of cross-platform programming confused. Recently in a cross-platform game, carefully looking at the matrix of the two, found that there is no big difference, the D3D left-handed matrix passed to OpenGL shader can work perfectly. Let's talk about some conceptual differences: (1) Different
In the second article of this series, we explained how to initialize the d3d rendering device !!! I admit that I am an irresponsible blogger, and I have not written anything in detail at all, hum !! (Proud ?) However, I think it is better to look at the d3d SDK documentation than reading the author's articles. That is the best teaching material. Okay, in this third article, the blogger is going to talk abou
D3D solution for YUV playback in WPF and wpfyuvd3d Solution During video media playback and monitoring system construction, YUV data is often displayed. Generally, the playback control and SDK use the Window handle to render the Window directly using DirectDraw. However, if the user interface is developed using WPF, it is generally only possible to embed WinForm In the WPF interface through WinFormHost. However, in this case, the AeroSpace problem occ
