Why use rasterization for web design

Grid design system (also known as grid design system, standard size system, program layout design, Swiss graphic design style, internationalist graphic design style) is a method and style of graphic design. The use of fixed lattice design layout, its neat and simple style, was very popular after World War II, and has become one of the mainstream styles of the design of today's Epitomy publications.

Today, raster systems are also being used in web pages. It uses a regular grid array to guide and regulate the layout and information distribution in a web page. For web design, the use of the grid system can not only make the information presentation of the web page more beautiful, easy to read, and more usable.

Try to be more popular: on a limited, fixed plane, use horizontal and vertical lines (virtual lines, "reference lines") to divide the plane into a regular series of "grids" (virtual grids), and rely on these grids, or use the edges of the grids as the reference line, to carry out a regular layout layout. Raster design is to divide the width of the web page into a fixed width of the same width, and then list the possibilities of various combinations, so as to facilitate the layout of the page when rendering, usually divided into 12 equal parts or 24 equal parts.

Once the triangle vertices have been converted to the correct 2D positions, they may be outside the viewing window or within the screen. Cropping is the process of manipulating triangles to fit the display area.

The most commonly used technique is the Sutherland-Hodgeman cropping algorithm. In this method, four edges of each image plane are tested at a time, and each point to be rendered is tested for each edge. If the point is outside the boundary, the point is culled.

For a triangular edge that intersects a flat face edge of the image, that is, one vertex of the edge is inside the image and one is outside, insert a point at the intersection and remove the outer point. <>

Raster (shān) lattice is a technical term in ps, raster is the pixel, rasterization is to convert vector graphics into bitmaps (raster images). The most basic rasterization algorithm renders a 3D scene represented by a polygon to a 2D surface.

In general, the term shān (polyphonic word is pronounced shān in professional software such as ps, raster is pixels) lattice can be used for any conversion of vector graphics to bitmapsraster image].

In common applications, the term is used to refer to the popular [[rendering]] algorithm for displaying three-dimensional shapes on a computer. Rasterization is currently the most popular algorithm for generating real-time [3D computer graphics]]. Real-time applications need to respond immediately to user input and typically require at least 24 frames per second.

Unlike other rendering techniques such as Radiation Shading and Ray Tracing, rasterization is very fast, but because it is not processed according to the physics of light transmission, it cannot properly simulate many complex real-world lighting environments.

The final step in the traditional rasterization process is to fill in the two-dimensional triangles in the image plane, which is known as the scan transformation. The first question to consider is whether a given pixel needs to be drawn. A pixel to be rendered must be inside the triangle, must not be cropped, and must not be occluded by other pixels.

There are a number of algorithms that can be used to fill within triangles, the most popular of which is the scanline algorithm.

Because it can be difficult to determine whether the rasterization engine will draw all pixels from front to back, there must be some way to ensure that pixels closer to the observer are not covered by pixels farther away. One of the most commonly used methods is deep caching, which is a two-dimensional array that holds the depth of each pixel corresponding to the image plane. The depth value in the depth cache is updated for each pixel to be drawn, and each new pixel is checked for the depth value in the depth cache before drawing, so that pixels that are closer to the viewer are drawn, and those that are farther away are discarded.

To break a grid, you first need to understand the grid system in depth. No matter what style of grid you're using, it's the "infrastructure" of your web design process, helping you determine how elements are to be placed, ensuring that different controls are stacked on top of each other on the page without being obtrusive and incongruous, and helping to keep the page organized.

In fact, designers in different fields have been using grids all the time. Take a look at the newspapers and books, which web designers were playing with before they started using rasters.

There are many things that a raster can do:

Keep your content organized. In a grid system, elements are clearly arranged from left to right and top to bottom, keeping the layout consistent.

This makes the design more efficient, because the regular grid makes the arrangement of various UI elements regular.

Make different pages of a web page look consistent.

Keep elements and spacing between elements the same to keep the whole design neat.

If there are so many advantages to grids, why break them?

It is not difficult to understand that the grid creates a consistent and coordinated look, and the elements that break the grid naturally appear more "glaring", which is undoubtedly an emphasis. There are many things that go into making this element break the grid and be able to match it with other elements.
