In a long vision of 3D reconstruction, when finding multiple frames of matching points and corresponding camera gestures, we need to find the matching points x and X ' and corresponding p and P ' I They get x = PX, x ' = P ' x. We get the two equations above, how to solve the equations. Here we go back to the 2D projection transformation to say, for the 2D plane on the two corresponding point Hx. H is a 3x3 matrix, so x and X ' are 2D coordinates in

3D conversion involves the knowledge of mathematics, as a graduate of the mathematics profession, does not study not to be sorry own profession?Let's start with a few parameters:1, Transform-origin:origin (origin, starting point), also namely the beginning of deformation, in mathematics can be understood as the origin of coordinates.Its syntax is:transform-origin:[The description for the normal language is:/* Set only the syntax for a value */Transfor

Title: 3D model Retrieval with adjustable view clustering based on viewpoint entropyBo Li,yijuan Lu,henry JohanAbstract: Searching for 3D models based on freehand sketches is intuitive and important for many applications, such as sketching-based 3D modeling and recognition. We propose a sketch-based 3D model retrieval

WPF 3D knowledge points and examples, wpf3d knowledge pointsIntroduction The reason is that a triangle is used to describe the most subtle ry of a plane. The rendering engine can calculate its color based on the material of each triangle and the lighting angle in the scene. In fact, it is three points to determine a plane. The calculation on a plane is the simplest, with the least factors taken into consideration. If three vertices in a

One, write in the front of the autumn pantsAs early as last year, I gave a big introduction to 2D transform related content. See the King of all know, the guy with D is not to mess with, 2D my generation still can cope, 3D words, hehe, estimated I wait long in the thousands of miles away by its domineering shock ~ ~Look at the movements and expressions of the female emperor, you can know the name of the guy with D!Some of the things that have recently

The current application of 3D GIS is mainly limited to 3D visualization and realistic visual performance, and its important 3D analysis and 3D operation functions are also very limited. The construction of three-dimensional spatial databases is still a complex and expensive comprehensive project. The production efficie

The boom in the Asian market for graphic electronic games is stimulating a huge demand for the next generation of mobile phones with complex 3D graphics Functions. This article describes in detail the technical challenges of 3D graphics technology in mobile phones, the 3D graphics API standards, and the technical competition that developers will face to help engi

If you randomly hold ten new users at the gate of the Computer City and ask them what they want to buy a new computer, I believe more than half of them will answer "Play Games ". Especially for a large number of students and computers, the time used to play games far exceeds the time used to learn and organize materials. Even for family users, there are also many people playing cards or Mahjong together, or playing FLASH games and even watching games on their computers. No matter how old or youn

IntroductionNow the concept of the Internet of things so fire, if the monitoring information can be real-time in the mobile phone's customer service to show us in the form of a, that experience you can play their own imagination.We still have a lot of places to use in our life, such as the use of Kinect in medical applications, and of course, somatosensory games and so on. There is nowhere to be found in 3D development.

Since many people are using JavaScript, HTML5 and WebGL technology to create browser-based 3D games, all JavaScript 3D game engines are a people's theme. The best part of browser-based gaming is platform independence, which can run on iOS, Android, Windows, or any other platform.There are a lot of javascript that can be used to create 3D games based on browsers,

Before learning React+webpack, accidentally passing through Webpack official website, see the LOGO on the top, it is very interested.Recently feel oneself CSS3 too weak, want to study in depth, so with this LOGO for the cut-in, study a bit about the related CSS3 properties. Webpack LOGO animation effect at first glance is not difficult, in-depth understanding, feel inside actually a lot of knowledge, oneself toss some, do a series of related CSS3 animation effect.First on the demo, do not focus
