DirectX: Add a custom filter (traversal filter in graph) to the graph Auto-link, filtergraph In the filter test program for video playback provided to the customer, the positive manual connection method (http://blog.csdn.net/mao0514/article/details/40535791) is adopted because of different video compression formats, the disadvantage of this method is that you cannot play any video file in time. Now, you can add your own filter to the automatically con

Today, we can see "Introduction to 3D game programming with DirectX 9.0" Translated by raymondking on csdn. it is a coincidence that it can be used as a supplement to learning glsl. I tried to analyze the scattering Illumination code implemented by HLSL in section 2.4 and found that the principle is basically the same as that of glsl. The code corresponding to section 6.2 of OpenGL shading Language// File: diffuse.txt // Desc: vertex shader that does

(1) first, regardless of DX or OpenGL, the vectors and matrices expressed are defined according to the standard in Linear Algebra:"The product of matrix A and B the element C (ij) in column J of row I of matrix C is equal to the sum of the product of the corresponding elements in column J of row I of." (Practical mathematics manual, Science Press, Second Edition)For example, C12 = A11 * B11 + A12 * B21 + A12 * b13... (2) After clarifying this, let's look at the "Storage Method of Matrices". Ther

screen.Four, flexible vertex format FVFIn D3D, vertices in a vertex cache actually contain a number of attributes, such as vertex coordinates, color, normal direction, texture coordinates, and so on. With the flexible vertex format, users can customize what information is included in the vertices, not all of them.Code:-----------------------------------------------------------------------------//file:createdevice.cpp////Desc : This is the first tutorial for using Direct3D.

. As for when to discard DirectX ManagementSimilarly, nooverwrite does not mean no overwrite. It only indicates that the developer thinks that the write location will not overwrite the vertex (draw) being used by dx, and does not need to wait until the video card draw ends (the default parameter 0 indicates waiting for the end ), overwrite the vertex data at the corresponding position directly (even if the vertex is being used for drawing, it will be

on the screen. The submit interface function is a set of methods to control the status of specific rendering devices that affect display.(1) Front-end buffer zone: This is a rectangular storage area converted from a video card. The content of this rectangular storage area is displayed on the display or other output devices.(2) Background Buffer: the background buffer is a surface and its content can be submitted to the foreground buffer.(3) Switching chain: a set of backend buffers that are sub

These two functions are not common troubles, especially BLT (); they are not completely involved at the moment. This is an example of a preliminary attempt: Code File: Unit unit1; interfaceuses windows, messages, sysutils, variants, classes, graphics, controls, forms, dialogs, dxdraws, stdctrls, DirectX; Type tform1 = Class (tform) dxdraw1: tdxdraw; button1: tbutton; button2: tbutton; Procedure button1click (Sender: tobject); Proce

In fact, DirectX is not very difficult. The key is to master the concepts and called functions, and there will be no more It is easy for beginners to forget to add a Library Link file in the project properties, so that they cannot run even if they have compiled the file.

Since the birth of the C + + language in the the 1980s, it is now more than 30 years old, and with the development of the C + + language, it has been applied in more and more fields.C + + is a multi-generic programming language that can be both process oriented and object-oriented. C + + is a very widely used computer programming language, so it has been more and more programmers are pro-gaze. C + + Related experts: C + + employment is very broad, compared to Java and other languages have a lot

The following code is the clock that the component implementation of the DirectX called. It has three pointers that will change in real time with the changes in the system. But I did not do the scale, because I think the program to draw the scale is not beautiful, using Photoshop to draw a bell as the background is much more beautiful.

(push the box). But even in the past, when we played primitive games, our imaginations often gave us more details than we could see. So what's your passion? Or what is your favorite type of game. It is a classic shooting arcade, fantasy adventure, real-time strategy game, role-playing game, or sports-related games. Hopefully readers will be able to design a game in their mind while reading this book, and as you learn each chapter in depth, you should imagine how to create the game. The book

course, the matrix in DX is 4 times 4, so let's extend it (this extension is really not good enough to explain it, just remember, it's not too hard) Okay, we'll go through two steps together: -pos R =-posx * Rx-posy * Ry-posz * Rz -pos U =-posx * Ux-posy * Uy-posz *uz -pos L =-posx * Lx-posy * Ly-posz * Lz (That is, multiply the two matrices, note the order, go first to the origin, and then turn.) Okay, so we get a look at the coordinate system transformation matrix. Through this long piec
