is, the font width is divided into nine levels. For example, OpenType uses the numeric level of nine values. Numbers are mapped directly to each level, 100 is mapped to the lightest font deformation, and 900 is mapped to the heaviest font deformation. In fact, there is no essential font width convention in these numbers. Css only emphasizes one point:The font width of each digit must not be less than the font width of the digit before it.That is to s

Forward Rendering Forward renderingforward renders a shader-based render path. It supports the calculation of light per pixel (including normal maps and light cookies) and real-time shading from a parallel light. In the default settings, a few of the brightest lights are rendered in per-pixel calculation of light mode. The rest of the light calculates the illumination of the object vertex.Depending on the light source that affects the object, the forward rendering path renders the object with a

increase the website operation cost, in addition, a single Server also has performance and thread bottlenecks. When the concurrency traffic is large and concentrated on one Server, "Server too busy" appears, in this case, what method should the webmaster use to make the website still have better access results when there is a high traffic volume? This involves the question of Server Load balancer. We have discussed CDN before. In fact, in addition to acceleration, CDN also has the effect of tra

Question: Use the Bubble Method to input 10 numbers from the keyboard and write code to sort the numbers.Analysis:The Bubble sorting method regards the elements to be sorted as vertical bubbles, and the elements with smaller values are relatively light and floating up. In this algorithm, this group of "Bubbles" must be listed several times; each processing time, two adjacent "Bubbles" values are exchanged. When the "bubble" with a higher position is greater than the value of another "bubble, the
