Three or four yuan to Euler angle conversionAs a result of arctan and arcsin, this does not cover all orientations (the range of values for the corners has been met), so atan2 is needed instead of arctan.Iv. use in other coordinate systemsIn other coordinate systems, the above formula should be adjusted according to the definition of the axis. As in Direct3D, the x-axis of the Cartesian coordinate system changes to the z-axis, the y-axis to the x-axis

Familiar with the media entertainment industry friends must be solid angle company and his renderer Arnold not unfamiliar. Arnold is a Monte Carlo Ray tracing-based renderer that is used by many Hollywood manufacturers and some studios. In particular, Sony Pictures Imageworks is mostly used Arnold rendering. Arnold also helped create a lot of good films, such as Monster House, which won the Oscar nomination in 2006, and cloudy with a Chance of meatbal

There is a basic Line class in Silverlight, which is used to draw a straight Line. In mathematics, you can draw a straight line by confirming the coordinates of two points, therefore, the Line class in Silverlight has four attributes: X1, Y1, X2, and Y2, which respectively represent the coordinate 1 of the starting point and the coordinate 2 of the end point of the Line. After the coordinates of these two points are set, a straight line can be displayed. The title of this article draws multiple

In iOS, a picture is rotated in radians rather than angles , so it is often converted between the two Radian to Angle #define RADIANS_TO_DEGREES(radians) ((radians) * (180.0 / M_PI)) Angle to radians #define DEGREES_TO_RADIANS(angle) ((angle) / 180.0 * M_PI)Excerpt from: Conversion of angles to radiansA

Transferred from: http://blog.csdn.net/heliang7/article/details/7309394The main question is how to calculate the length and width of the new image after the image has been rotated.With the help of Java 2d and the basic math library, you can actually use simple calculations to know.The following algorithm only calculates the formula when the rotation is less than 90 degrees. When the rotation is greater than 90 o'clock, the problem domain can be converted to a sharp

How to reasonably label the angle of two non-parallel segments. For example, for the following two initial line segments: Depending on the location of the current mouse, we may obtain the following different annotation methods: The general idea of self-tagging is: first, find the two endpoints of the arc (dimension line), and then calculate the two endpoints based on the two obtained endpoints, respectively, and calculate the two leads

In 3D graphics, the most common rotation representation method is the four-element and the Euclidean angle, which saves storage space and facilitates interpolation compared with the matrix. This article mainly summarizes the conversion of two expressions. The calculation formula uses the 3D Cartesian coordinate system: Figure 1 3D Cartesian coordinate system (from Wikipedia) It is defined as the rotation angle
