Use vector dot product to rotate the model around the center
How to rotate a model around the center in a 3D space? This problem sounds easy, but after my practice, I found it quite difficult. In the initial stages of studying OpenGL and DirectX, I believe this problem still hurts everyone's brains. How can this function be implemented? I think you may need to go back and review our high school knowledge. T

Describe
In linear algebra and computational geometry, the vector dot product is a very important operation.
Given two n-dimensional vectors a= (a1,a2,..., an) and b= (B1,b2,..., bn), find dot product a· b=a1b1+a2b2+...+anbn.

We have analyzed in detail the method of rendering filters for special effects in Photoshop filters for making simple cloud effects. today we will introduce a specific example-colored dizzy glass. 1. in Photoshop, use the default black/white color to execute [filter _ rendering _ cloud]. The effect is shown in. 2. use [filter _ blur _ Gaussian blur]. then, we have analyzed in detail the method of rendering filters for special effects in "Photoshop filter for simple cloud effects, today, we will

First, let's first paint the two graphs, turn off the strokes of the two graphs, set the small star to dark gray #4d4d4d, and the large star to remain white. Select two stars and enter object > Mix > Build, at which point the blending tool turns the graphic into a gradient transition star.
