How to Use the ode physical engine in the irrlich Engine TranslationNote: ODE is an open-source rigid physical engine, which sounds scary. in fact, it is not complicated, and it is not difficult to combine with the rendering engine. just a few small steps to convert the data, call the ode process, rendering engineWith powerful collision detection and other physi

FFT IP Core FeaturesParameter settingsThere are 4 modes of the FFT IP core, namely: Burst mode (Burst); Cache burst Mode (Buffered Burst); Flow mode (streaming); Variable flow mode (Variable streaming); In the first 3 mode, the operation speed is increased, and the occupancy resource is incremented, and the 4th mode (Variable streaming) can be used to change the

Introduction to ODE and platform building. The author came into contact with the dynamic simulation engine because a PLC simulation software required 3D simulation. what I need to achieve is

"I always thought Lao Tan had a family ..." at noon, I went out to stroll and hear some of the girls behind me chatting, and I thought they were in the gossip of friends around the road. "No, from beginning to end also did not see old Tan has a family, old Tan is like Andy's, he said ' I like her, but I cannot guarantee can give her a controllable future ' ..." the moment suddenly dawned, the original they chatted is the recent hit "Ode to Joy". The p

2 weeksI am dead in these five physical engines.I can't say I understand it very well.A simple understanding What I want to say most is that docization is really important ....Among the five, novodex is the best documented.Very detailed, including the idea of engine implementation. Every member of each class has a clear explanation of what it is.The other four are getting worse.The worst keys are tokamak and bullet.Where Tokamak is the differenceI can't even use official forums, and I still hav

Ode is a free library of rigid body dynamics with industrial quality. It is an excellent open-source physical engine.ProgramEmployee RussellSmith and several open-sourceCommunityDeveloped by the contributors. It can simulate movable objects in the real environment. It is fast, robust, andPortable. It also has a built-in collision detection system. My main job is to studyOde physical Engine Applications in 3D games. The research mainly involves learnin

Features: 1. Based on the Mass Point model, non-damping vibration and damping vibration are achieved. 2. Developed the cloth mesh. 3. Import the OBJ sphere model and simulate the soft body. 4. Calculate the volume of soft body using a simple method. Use the mass-spring model to simulate the fabric. Import the OBJ model and use the mass-spring model to simulate the soft body.The following is the bounce of the soft body on the ground. The basic practice is to apply additional force

Ode is used to simulate the movement of tanks. tanks are not like normal four-wheeled vehicles (hing2 can be used to implement wheels). To provide power for the tracks at the ground contact, contact motion is used, it was originally used to achieve the conveyor belt effect. Method: a tank is combined with a crawler. The tank body uses box Geom, and the two tracks are replaced by two boxes Geom.The dynamic speed (surface line speed) of the two track

Recently there is a "Ode to Joy," the TV series is very hot, posters have done very well, today gifted @ security eggs to the students to bring a copy of the tutorial, the effect of super dazzle, and the operation is particularly simple, welcomed the students to their favorite love beans to a picture. 　　Original: First, let's take a look at the final chart of the tutorial: The first step, we have to find a suitable picture o

The question should be understood in this way: 0 after the DfT (FFT is a fast DFT algorithm), in fact, the formula has not changed, the change is only the frequency domain terms (such as: 0 before the FFT calculation is m*2*pi/m at the frequency domain value, and 0 after the n*2*pi/n at the frequency domain value), M is the original DFT length, n becomes the length of the complement 0. Will (-PI,PI) from th

Often can be seen in the literature 2d-fft can be achieved by two 1d-fft, today I use MATLAB to prove that, indeed. The code for MATLAB is as followsClear All;clc;f=ones (256,256); center_loc = size (f); rd = 2;f (Round (Center_loc (1)/2)-rd:round (Center_loc (1)/2) +rd, Round (Center_loc (2)/2)-rd:round (Center_loc (2)/2) +rd) = 0;figure (1); Imshow (f); f2=fft2 (f); f3= (ABS (F2)); figure (2); Imshow (F3)

Some time ago, by Liu Tao, Shanxin, Yang Chi, Wang Ziwen, Choshin and other starring "Ode to Joy" in the major TV broadcast. As early as the premiere, small also had a warm anticipation, because the play has "male God", there are wood. However, after a few episodes, small series found that many friends around the same sigh: even if no man in the play can see the same! You can do it?! Small also found that, compared to the emotional line of the charac

FFT is a high-speed algorithm for discrete Fourier transform, which can transform a signalto the frequency domain. Some signals are very unsightly in the time domain, but asWhen the fruit is transformed into the frequency domain, it is very easy to see the features. That's a lot of signals.Analyze the reason of using FFT transform. In addition, the FFT enables th

FFT (Fast Fourier transformation) is a classic algorithm used for digital signal processing. Many people who have studied DSP or chip design know this algorithm. However, have you ever wondered why there are so many FFT operations in digital signal processing? Some may say that in order to analyze the signal spectrum. The problem below is to analyze the daily needs of the spectrum, such as mobile phone call
