-reflective lenses to reduce the glare effect, better than computer goggles. Screen update If the screen is still an old-fashioned negative tube (CRT) display, adjust the refresh rate to 75Hz or above to reduce the flashing frequency. We recommend that you replace it with a flat LCD to reduce the glare and eliminate the blinking of the CRT screen. LCD or text displayed on a new and energy-saving LED screen are clearer and smoother than CRT display. M

Li Guangyuan rolled around and rolled the bed cold. He hangs on two legs without heat, and the shadows in his head keep changing. She had no bangs, and she wore black contact lenses, which made her eyes exceptionally black and electric. Although there is still a certain gap between her appearance and Li Guangyuan's imagination, and there is still an ugly mole on her right face, Li Guangyuan still believes that she fell in love with her. He remembered

Digital subtraction angiography system

each pixel is coupled to the photoelectric layer, so that the image has a high brightness, improved I. I conversion efficiency, so it is very promising. Currently, the high-performance I. I quantum detection efficiency (DQE) reaches 85%. According to some materials, the resolution is up to 6.8lp/mm. 3. to adapt to the large X-ray dose range (that is, the variation range of input light), the optical system requires the use of large aperture, aperture can automatically adjust the lens, some

Getting started with depth of field

focusing clarity. * Change the distance between the camera and the subject. As I have mentioned, the depth of field is affected by the distance from the camera to the subject. When you focus on something very close to the lens, the depth of field is very small. When you focus on a distance, the depth of field will be larger, and the depth of field will change due to different focal lengths. Tip: Take close-up photos, such as macro photography. Remember that the depth of field is calculated in i

Discussion about headset

monthly salary is RMB 3000, and the cost is RMB 30-40 to buy a headset. It is unlikely that I will run in for a few months because of a 30-40 yuan headset. The reason is:1) What is the theoretical basis of pot? Is it based on your own ears?2) headphones have a lifetime of vibration. The method is the player's statement or the manufacturer's statement.I like photography. I know a lot about photography, or even the so-called photography Masters about equipment maintenance orThe feeling of pho

Analysis of FFT Lens Effect

horizontal lens glare similar to Star Trek 11, and almost require a full-screen kernel, which is hard to afford for real-time applications. (J.j. Abrams uses this horizontal lens flare in many films) FFT Method In fact, the effects of all these lenses are blur, that is, convolution of each pixel with a kernel. There is a convolution Theorem in mathematics: That is It indicates convolution, Fourier transformation, and inverse Fourier transformation.

Terrain System (translation)

, and then returns to drag other bricks. Some games allow you to modify tiles, change textures, and scene types to create desert, grassland, or forest. When players are not close to the ground, it is a very good way to make the terrain. However, this method cannot bring a wide variety of height changes to the terrain. Advantages of brick-making terrain: ■ Simple and interesting to use ■ Fast production Disadvantages of tile terrain production: ■ Restricted by brick laying and terrain objects in

increased every second. Run the command (without pseudocode, compile and execute it again). The number takes about 10 seconds to jump. In fact, this method is enough for scenarios with low precision requirements. I used to write a jsgplayer to play tunnel ad files in a custom format. This method is used for inter-frame latency, because it is a simple player that does not require high precision, although the frame rate may be somewhat different, the effect is indeed acceptable. Now, because we n

Basic Theory Based on physical Rendering

rendering is that when it occurs on the surface of an object, the scattering effect between light and air and matter. At this time, the plane scattered light is divided into two parts: the part that enters the plane (refraction, absorption or scattering in the internal propagation of the object), the part that goes out of the plane (reflection ). A plane (optical plane) reflection that assumes perfect infinite optical flat. The air and objects on both sides of the plane have their own refractiv
