Polarized Light
Definition of natural light:
In a common light source, the light wave columns emitted by a single atom are polarized, and the vibration directions of the light wave
Traffic Light Signal Simulation System
I. Overview
Simulate the traffic light management system logic at the crossroads. The specific requirements are as follows: (The requirements are directly from the instructor's documents)
① A vehicle traveling along each route is randomly generated asynchronously.
For example:
Vehicles from south to north-direct vehicles
Vehicles going from West to south-turn right

General OrderWithout a light source, it is impossible to see any rendering results.
ambientlight: ambient light, base light, and its color will be loaded into the entire scene and the current color of all objects.
pointlight: Point light to emit light in all dir
Tutorial
We are talking about the comics, usually refers to the black and white comics, the basic principle of this kind of comics is through lines, black and mesh point to show the real life of the object contour and light and shadow performance.
Therefore, the production of black and white comics is necessary to carefully study the various properties of light and shadow of various forms of expression.

Note: The article is translated from http://wgld.org/, the original author Sambonja 広 (doxas), the article if there is my additional instructions, I will add [Lufy:], in addition, The WEBGL research is not deep enough, some professional words, if the translation is wrong, you are welcome to correct. The results of this demo runilluminate the worldThe last time a doughnut-like ring model was drawn, although no special new knowledge was involved, the 3D model was successfully plotted. So, take a
According to the light model in the book, the type of light is divided into 3 kinds: diffuse light, ambient light, mirror light.The type of light source is also three kinds: parallel light, Spot
I. Project requirements:Simulation realizes traffic light management system logic at intersection. Detailed requirements such as the following:1. Asynchronously randomly generates a vehicle that travels according to each route.Like what:Vehicles travelling north from south to----straight vehiclesVehicles from West to south----turn right.Vehicles from east to south----left-turn vehicles。。。2. Lights ignore the yellow
I. Requirements
The traffic light management system logic at the intersection is simulated. The specific requirements are as follows:
Asynchronously and randomly generate vehicles traveling along each route.
For example:
Vehicles from south to north-direct vehicles
Vehicles going from West to south-turn right
Vehicles from the east to the south-turn vehicles
......
Ignore the yellow light, only the re
Basic knowledge of light sources
Characteristics of light sources
The characteristics of the light source itself, such as the spectral distribution of the light source, the luminance distribution on the irradiated surface, the temperature characteristic and the life span of the
I. Project requirements:Simulate the intersection of traffic lights management system logic, the specific requirements are as follows: 1. Asynchronously randomly generates vehicles that follow each route.For example:Vehicles travelling north from south to----straight vehiclesVehicles from West to south----turn right.Vehicles from east to south----left-turn vehicles。。。2. Lights ignore the yellow light, only consider the red and green
No lights the world will be a dark, in the 3D scene is the same, exquisite model, real material, perfect animation, if there is no light to illuminate everything is useless, so that the application of lighting in the scene replay is the most important step is not excessive. In addition, lighting is not only a place to add lighting in the scene, if so 3DS Max provided the default lighting is enough. In fact, the role of lighting is far more than this,
The light blog is a kind of internet product TUMBLR by foreign website. Twitter and other microblogging products after the popular, netizens found that 140 words of speech is too simple. So Tumblr, of course, it allows users to publish text and all kinds of multimedia content, while maintaining the Twitter attention, forwarding characteristics, so that the chain of micro-bo communication and blog multiple content performance of the perfect combination
PS is the strength of the mix between layers, if you do not light and the basic principles of color, then you see the great God's tutorial does not know how the color effect is produced, learning is simply a step and process, so never have their own real original things.
When it comes to light and color, let me not say anything else, but first look at how the color is displayed in PS.
Open your PS Color s
Diffuse lighting (diffuse reflection light)
Different materials have different ways of reflecting light on the surface. The reflection angle of mirror glazing is equal to the angle of the body. When a strange glow is seen in the eyes of a cat, this is the reflection of light: This is because the cat's eyes reflect light
In the previous chapter, this chapter describes the use of three lights (parallel light, point Light, Spotlight). Introducing Header Files#import ' NVWorldLight.h '1, creating a parallel lightin theonCreateinside the instance light object, code such asCode:// lights, ground, particles belong to the World object, so you need to create from Nvworld // first verify
OpenGL can set at least 8 light sources, which are labeled gl_light0,gl_light1,gl_light2 .... Here we use two kinds of light sources, one is ambient light and the other is a spotlight.When setting up lighting, we need to consider three kinds of light: ambient reflection light

1. Traffic light Management System project requirements
Simulation to achieve the intersection of traffic lights management system logic, the specific requirements are as follows:
Ø randomly generated vehicles that follow each route.
For example:
Vehicles coming from the south to the north----straight vehicles.
Vehicles from the west to the south----turn right
Vehicles from east to south----left-turn vehicles
。。。
The signal lights ignore the yellow
The type of light we are discussing here has the same point, that is, we are considering a point on the light source, the effect on the surface of the object, that is to say, the three-dimensional angle is approaching zero.Here the light source is divided into two categories, one is directional light, assuming the
