Http://blog.csdn.net/bailang71/article/details/1966158 Windows form programming coordinate system type GDI + uses three coordinate spaces: World, page, and device. World coordinates are the coordinate systems used to establish special world models in graphics. They are also the coordinate systems passed in. NET Framework. The page coordinate system refers to the coordinate system used by a drawing (such as a form or control. The device coordinate system is the coordinate system used by a physic

The mathematical principle of matrix In Android, if you use the matrix for image processing, you must know the Matrix class. The Matrix in Android is a 3 x 3, which reads: The matrix image processing can be divided into four kinds of basic transformations: Translate Translation Transformation Rotate Rotation Transform Scale Scaling Transform Skew Error-Cut transform Literally, the Mscale in the matrix is used to handle the sca

transformation of, VectorP,Q,RIt is called a base vector. Here, the base vector is the Cartesian coordinate axis, but in fact, a coordinate system can be defined with any three base vectors. Of course, these three base vectors must be linearly independent (that is, they are not on the same plane ). ToP,Q,RCreate a 3x3 matrix m for the row and obtain the following matrix: Multiply the matrix by a vector to obtain the following result: If the line of the matrix is interpreted as the base vector

Conversion combination Imagine an object in any direction and position in the world. We want to render it to a camera in any direction and position. To achieve this, all vertices of an object must be transformed from the object coordinate system to the world coordinate system, and then from the world coordinate system to the camera coordinate system. The mathematical transformations are summarized as follows: Matrix Multiplication satisfies the combi

I_dovelemonSource: CSDNDate: 2015/5/18Topics: affine transformations, orthogonal matrices, inversion, matrix multiplicationIntroductionLong time no blog, this period has been busy, today to write down the internship when the problems encountered, while continuing to update their blog.What I want to say today is some of the doubts about the 3D transformation. Mainly in what is affine transformation? What is an orthogonal matrix? How to find out the inv

;--Converts an arbitrary vector into a unit vector, called normalization. Divides the vector by the length of the vector.8. Point multiplication:--Two three-dimensional vector point multiplication is a scalar;--Represents the length of a vector projecting to another vector;--in the unit vector, the point multiplication of two vectors is the cosine of the angle;9. Fork Multiplication:The cross-multiplication of two vectors is a third vector perpendicular to the two vectors;Purpose: To calculate t

OpenGL is a large state machine. We implement scene rendering by changing its State. 1. Basic matrix transformation: Model Transformation: Models in mobile and transform scenarios; Projection Transformation: Crop and distort the visual space; View Angle conversion: scales the final output. Matrix Transformation Through the first three chapters, we learned how to use OpenGL to draw basic elements in 3D space and form a model using elements. However, after drawing an object or scene, we always wan

, is not the key nature. Only the 4th is the nature of space, that is to say, accommodating motion is the essential feature of space . Recognizing this, we can extend our understanding of three-dimensional space to other spaces. In fact, whatever the space, it must accommodate and support the occurrence in which Rules-compliant motion (transformation). You will find that there is often a relative transformation in some space, such as topological transformati
