First review the elementary school Chinese text, Hua's "overall method". For example, want to brew pot of tea to drink. At that time, there was no boiling water, the kettle was washed, the teapot was washed, the fire was born, and the tea was there. What to do? Method A: Wash the kettle, pour cold water, put on the fire, in waiting for the time to open, wash the teapot, wash the cup, take tea, an

L, R indicates the volume range of tea in a pot L ~ R, not sure about the exact amount (integer). Now I need to pour tea into the two cups (regardless of the capacity of the cup), so that the difference between the two cups cannot exceed 1, the remaining tea in the teapot cannot exceed 1, and the minimum number of tea pouring is required. For example: 2 2. The answer is 1. We can pour 1 to the first cup, the second cup does not fall, so the differenc

If you change 10 to-10, you can see from the front of the 3D teapot. Below are two: The following function draws a red teapot. First, clear the color buffer with the clear color black (glc

The Geometries of Balder provides many existing models, such as cubes and columns. However, when developing games, we usually use 3D design tools to create custom 3D models, this article describes how to import and display a custom 3D model. First, let's look at the built-in Geometries model. You can view it in the object browser or Geometries. The Heightmap in it will be introduced later. This time we will mainly introduce Mesh (Mesh object) and use it to import custom models. Then, prepare a

This tutorial introducesToon shader)Method,Cartoon rendering is a non-photorealistic rendering or a type. Cartoon rendering an object looks like a cartoon painting. Here is a simple method for rendering cartoon effects. Unlike general light rendering, the color transition between the pixels of objects rendered by cartoon effects is a step function, the color transition of objects rendered by light is a smooth continuous function. Figure 1 compares the cartoon rendering with the pixel-based rende

of imagining a matrix in 2D is to imagine the "L" shape composed of row vectors. In this example, we can clearly see that,MIt indicates that the part is rotated 26 degrees counter-clockwise. Of course, all vectors are affected by linear transformation, not just base vectors. The most intuitive impression of transformation can be obtained from the "L" shape, the Complete 2D parallelogram composed of the base vector helps to further see the impact of the transformation on other vectors, as shown

Gouraud ). Each pixel calculates light separately. 2nd sheets: The colors are flat, Gouraud, and Phong respectively. Compared to the 1st images, the mirror light is added (note that the white spot appears in many places of the teapot ). 3rd sheets: Texture is introduced on the basis of the previous one. Pay attention to the spot on the nozzle. The depth buffer is not enabled for this group of images, so the display is incorrect. 4th sheets: High

Forget when in where to see a rotating effect, the brain is hot, just I just learned a little 3DMAX, I imitated such a super simple super naïve effect. I hope we can borrow methods do not borrow effect, or I have become a sinner, fraught may not be good, good, I immediately introduce the general practice: First of all you want to 3DMAX, not too strong, I am also rookie level, but w
