spectrum dx10

In the process of acoustic signal processing, we often encounter the following concepts: energy spectrum, power spectrum, octave spectrum,1/3 frequency range spectrum. There are differences and links between these concepts. Some of these concepts are often mixed when people talk about problems. A little bit of time lat

DX10 engine plan-bullets and dx10 engine bullets Today, I changed the bullet release mechanism to "collision N times" or "death (suicide)" after a period of time ). The difficulty is to commit suicide. It is difficult to ensure that the system will not "return to Soul" after the suicide ". After searching for a long time, I finally found out which statement is called "soul ": This sentence is the fault. If

1. Energy and Power Signals If the energy of the Signal Integration can be obtained, instead of infinity, that is, the energy is limited, and the average power in all time is 0, the signal is an energy signal. If the energy is infinite, the power is used to describe the energy of the signal, which is the power signal. Any signal is either an energy signal or a power signal, because the power of the signal can never be infinite. 2. spectrum, energy

During spectrum analysis, FFT has the following four errors: (1) spectrum mixing: The nequest theorem has been well known, so almost everyone knows that in order to avoid spectral mixing, theoretically the sampled spectrum is greaterThe highest frequency of the signal. What is the relationship with the time domain? The reciprocal of the sampling period is the

Spectrum: The dynamic signal is analyzed in the frequency domain. The analysis result is the spectrum lines and curves of various physical quantities coordinate by frequency, and the spectrum function f (ω) with various amplitude as the variable can be obtained ). The spectrum is a very rigid thing. It often refers to

Spectrum Analyzer is the use of frequency domain to analyze and study the signal of a measuring instrument, for signal analysis it is indispensable, with the rapid development of communication technology, more and more field operations need to support the spectrum instrument (Spectrum Analyzer type), such as communication transmitters and interference signal meas

John Carmack reproduce body description dx10 Occasionally, I saw an interview with John Carmack (author of the quake engine, not forgotten) by game informer in August. The paid comrade was already very happy to use DX9 to develop the Xbox game. "DX9 is really quite a good API level... Microsoft has done a very, very good job of sensibly evolving it at each step -- they're not worried about breaking backwards compatibility -- and it's a pretty clea

Android mobile games released weapon spectrum, android mobile phone Spectrum Collation In the spring of 2013, as the company entered the mobile game publishing industry, it witnessed the entire industry boom, struggle, shuffling, and silence. From hundreds of games, hundreds of releases, to now hundreds of games, several releases. After a round of shuffling, most publishers have been overwhelmed by several

Many users agree that only the latest Vista system supports dx10 and Windows XP cannot run dx10 games. This is Ms's official statement, but it is not true? The answer is no. However, it was reported on the Internet that a simple method can be used to run the latest crysis game in the WINXP system and obtain the same picture quality as dx10. In the crysis-online

I have been working on shadow recently. A "sideline" is to replace all the things originally implemented with fixed pipeline with shader. Why? I believe that anyone who has done Shadow Mapping demo knows this. Now that shader is used to implement lighting, simply use per-Pixel Lighting. Consider spot/fall off and far/near attenuation. In this case, a mesh may be affected by multiple light sources. Therefore, a dynamic shader merge mechanism is required to dynamically generate a combination of d

Today, with the Cuda example, a rotated polygon is drawn in a CU file.1. In the CU Riga Dxmath header file will be error, not resolved, and finally wrote a few math functions2. When binding the VertexBuffer and Cudaresource in CPP files,hr = Pd3ddevice->createbuffer (BD, NULL, g_pboxvertexbuffer);Where the DESC BD does not have a BD set. miscflags= 0; And then it can't be drawn.D3d10_buffer_desc BD;BD.

).*****************************************I think of two solutions,Workaround 1: Adjustment the condition for judging 0 is the minimum speed valve. This method can only be estimated, there is an unstable error, because there is a one-step point multiplication operation. I ruled out the method. Adopted the second type ofSolution 2: The processing point multiplication product is 0 without special treatment, through the subsequent Momentum theorem processing, and the next cycle of the minimum spe

. Put some pictures of yourself DX11.Learning experience Sharing:At that time I took a lot of detours, did not find the Chinese version of the DX11 textbook (domestic is some, the following I will introduce how to find), the use of textbooks is not dragon book, but the online very easy to search the Chinese version of the "DirectX 11 Game Programming Primer ", this book is Ben Ben, The knowledge point in the book is very shallow, almost can be said to be a sentence; What Steiger surface, specula

In order to practice English and share what I have learned about the instanced tessellation, I wrote this artical, just talking about the instance tessellation pipeline, not the mathematical research about the surface soomthing. -- zxx Days buried myself in *. CPP and *. PDF files, I finally got the idea of the instanced tessellation, which has been implemented in the earlier days after when dx10 is released and NVIDIA added a geometry process part t

Switch from "driver home"Source: http://news.mydrivers.com/1/89/89046.htm At Siggraph 2007, a world-class computer graphics image event held in San Diego, California last week, Microsoft officially confirmed that Windows Vista SP1 will upgrade DirectX to 10.1. When introducing the features of dx10.1, there is a saying that "Supported on upcoming Hardware". We can understand it as "the latest hardware supports ", it can also be understood as "only the latest hardware will be supported ". Recent
