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

time, the physical pixels represented by 1px in the CSS will also increase by one time, whereas the physical pixels represented by 1px in the CSS will be reduced by a factor of one time. So, with the above description, we can get the following conclusion:Page scaling = physical pixels/css pixels1.3 DpippiThe definitions for DPI and PPI in reference http://weizhifeng.net/you-should-know-about-dpi.html are as follows: DPI (dots per inch) is the number of ink points the printer can s

resolution of the device is, whether the pixel density is different or not, the pixels should look as big as they are. If consistent compliance is achieved, this standard will ensure that pixels are consistent in any design work and on any platform, regardless of the pixel density or the distance from viewing. The reference pixel is really good, but now there i

Our algorithm completely retains the scaling feature information of the original input pixel image, and generates a sh
