  • AK: Hollow Triangle (Basic Computer Test Questions)

    Time:2022-8-17

    By hollowing out a character triangle, you can save material costs and reduce weight, but the key is to pursue another visual effect. In the process of design, it is necessary to give various patterns of materials and triangular templates of various sizes, and make them temporarily through the computer in order to see the […]

    Rasterization Comprehensive Analysis 0 Two methods The rendering process in graphics can basically be broken down into two main tasks:Visibility and Shading. Rasterization can be said to be a solution to the visibility problem. Visibility includes being able to tell which parts of a three-dimensional object are visible to the camera. Some parts of these […]

    1、 Concept definition The so-called greed always makes the best choice at present. In other words, without considering the overall optimization, what the algorithm gets is in a senseLocal optimal solution。 For example, for an array of positive integers, I want to find two of them to maximize their product. There is no doubt that […]

  • Web GL enters the three-dimensional world

    Time:2022-5-25

    Three dimensional objects are composed of triangles, so we need to draw each triangle of the object one by one as before, and finally draw the whole three-dimensional object, but there is a significant difference between three-dimensional and two-dimensional. When drawing two-dimensional objects, we only need to consider X and Y information, but when drawing […]
