The OBJ file does not contain the color definition information, but can reference the material library. The material library information is stored in an independent file with the suffix ". MTL. The keyword "mtllib" indicates the meaning of the material library. The material library contains the definition values of diffuse, ambient, specular RGB (red, green, and blue), specularity, and refraction of materials ), transparency and other features. After

one standard form of getting the string representation of an object. Python is available in two ways.1.1 repr (): Returns the string representation of an object in a way that is easy for developers to understand .1.2 str (): Returns the string representation of an object in a way that is easy for the user to understand .1.3 Implements __REPR__ and __str__ special methods to provide support for repr () and STR ().1.4 repr,str, and __format__ all return Unicode strings (str type). Only the __byte

Advanced browsers such as FIREFOX,CHROME,OPERA,SAFARI,IE9,IE8 can directly use the stringify () and Parse () methods of the JSON object. Json.stringify (obj) converts JSON to a string. Json.parse (String) converts a string to JSON format; var a={"name": "Tom", "Sex": "Male", "Age": "A"}; var atostr = json.stringify (a); alert (ATOSTR); Result: {"name": "Tom", "Sex": "Male", "Age": "24"} Result: string var b= ' {"name": "Tom", "Se

Today I'm going to summarize some of the things ES6 does with functions. Combined with my ES5 function features, can let us according to the actual situation, to very good completion of our project requirements. One, ES6 arrow function 1. Arrow function with parameter Let fun = (x) => x console.log (Fun (2))//2 This is equivalent to the ES5 function Fun (x) {return x } Console.log (Fun (2)) //2 2. Give

The JavaScript arrow function is an easy way to write function expressions introduced in ECMAScript 6. Typically, in JavaScript, you can create functions in two ways: function statements. An expression of the function. You can create a function statement as follows:function add(num1, num2) { var res = num1 + num2; return res;}var sum = add(7, 2);console.log(sum);You can also create function expressions of the same functionality as

Recently I want to revise this website, I want to put a prompt box above. It's easy, but I want to have a triangle arrow on the Cue box. However, the thought of this requires the use of pictures, and various colors, arrows in various directions to prepare countless kinds, which is almost a disaster. Fortunately, MooTools's core developed Darren Waddell told me a great technique: Draw triangle arrows with CSS. With pure CSS, you can create a wide range

1 Basic usage ES6 allows you to define functions using the arrows (=>). var f = v => v; The above arrow function is equivalent to: var f = function (V) {return V; }; If the arrow function requires no arguments or requires more than one argument, a parenthesis is used to represent the parameter portion. var f = () => 5; equivalent to var f = function () {return 5}; var sum = (NUM1, num2) => num1 + num2; e

, b) => {if (a - b > 0 ) {return1}else{return-1}})arr// [1, 2, 3, 4, 8, 9] 　　Second, the attention point1. The typeof operator is the same as the normal function 12 varfunc = a => aconsole.log(typeoffunc);// "function" 　　2. Instanceof also returns True, indicating that it is also an instance of function 1 console.log(funcinstanceofFunction);// true 　　3. This fixed, no longer fickle 12345678910111213
