Ctional light per pixel)In this section, we will change the previous shader code to the direction light calculated by pixel. We need to split jobs by two shader to determine which operations need to be performed by pixel.First, let's look at the information received by each vertex:• Normal• Semi-Vector• Light Source DirectionWe need to transform the normal to the viewpoint space and then normalize it. We al

Resolution, pixel, and PPI, resolution, pixel PPI Screen SizeIt refers to the length of the diagonal line of the screen, generally in inches, 1 inch (inch) = 2.54 cm (cm ). In the traditional sense, the photo size is also the concept. Therefore, screens of the same size (diagonal) may have different aspect ratio.Pixel: This is an abstract concept in a bitmap (such as a digital image). It refers to the compu

(Click here for the original article link) Author: Johannes Kopf (Microsoft Research Institute) and Dani lischinski (Hebrew University) Summary We propose a novel algorithm to export a smooth, resolution-Independent Vector image from a pixel image, which can be scaled up without distortion. Our algorithm completely retains the scaling feature information of the original input pixel image, and generates a sh

Objective In our impression, Flash is based on a set of vector design software, bitmap is not conducive to scaling, and the location of each point of the bitmap and color must be stored, so the bitmap file will be relatively large. Therefore, the general flash used in almost all vector map resources. So, the bitmap in Flash is really useless? You can take a look at the example I've done: Click here to download the source file Is the effect OK? This is the legendary

In screen-based design, pixels are always the smallest unit. Because it is inseparable, it becomes a tangible unit for the designer to measure the screen distance. In the past, I heard people say: "A pixel is a pixel ." This sentence is intended to help flat designers who are not accustomed to Fixed Screen density understand the concept of pixels. Because of this consistency, web designers also use pixels r

In the book 3D Mathematical Fundamentals-graphics and game development, we see the concept of pixel-to-width ratio. Of course it's good to understand that pixels are squares, so the pixel-to-width ratio is 1. For pixel aspect ratio details, please refer to msdn:https://msdn.microsoft.com/zh-cn/library/cc294571.aspx, I will parse the meaning of the formula after q

Pixel In English pixel, the abbreviation of image elements (picture element) is the number of points in the unit area that make up the image. Each pixel has a different color value. The more pixels in the unit area, the higher the resolution, the better the effect of the image. Pixels are sometimes referred to as PEL (the abbreviation for picture element). The

The pixel padding rate refers to the number of pixels that the graphics processing unit renders per second, in mpixel/s (million pixels per second), or gpixel/s (1 billion pixels per second), which is the most common metric used to measure the pixel processing performance of the current display chip. The rendering pipeline is an important part of the display core and is a set of specialized channels in the
