利用three.js实现一个记录两个人走过岁月的点点滴滴的idea
碰巧我们在一起两周年，花了两天码了一个走心的礼物，于是就有了这个小项目的来源
首先看下实现效果图---一个音乐播放，带图片切换的时间记录器
-
雪花飘落效果实现
1.把五张图片充当雪花，然后three.js3D库 + 定时 营造出雪花飘落的效果，大致代码如下：
function init() { camera = new THREE.PerspectiveCamera(75, containerWidth / containerHeight, 1, 10000); camera.position.z = 1000; scene = new THREE.Scene(); scene.add(camera); renderer = new THREE.CanvasRenderer(); renderer.setSize(containerWidth, containerHeight); for (var i = 0; i < snowNum; i++) { var material = new THREE.ParticleBasicMaterial({ map: new THREE.Texture(particleImages[i % 5]) }); particle = new Particle3D(material); particle.position.x = Math.random() * 2000 - 1000; particle.position.y = Math.random() * 2000 - 1000; particle.position.z = Math.random() * 2000 - 1000; particle.scale.x = particle.scale.y = 1; scene.add(particle); particles.push(particle) } container.appendChild(renderer.domElement); document.addEventListener("mousemove", onDocumentMouseMove, false); document.addEventListener("touchstart", onDocumentTouchStart, false); document.addEventListener("touchmove", onDocumentTouchMove, false); setInterval(loop, 1000 / 50) }
-
倒计时 1.这个不用多说，给一个起初时间和当前时间对比，然后操作对应的dom元素,然后控制title
countTime('2017/02/12 00:00', 'day', 'hour', 'minute', 'second'); var days = parseInt($('#day').text()); var years = new Date().getFullYear(); var month = new Date().getMonth() + 1; var dateDay = new Date().getDate();
-
图片，描述文字的切换 1.为了避免图片过多同时加载缓慢问题--这里js设置一个图片列表和对应两个图片描述两个变量，同时为了保证图片加载出来才切换图片描述文字，用到了img的load事件函数
curImgDom.src = imgList[imgIndex]; // curImgDom.setAttribute('src', imgList[imgIndex]); if (isInitImage) { $('.img-intro').text(imgDescList[imgIndex]); return; }else { // curImgDom.src = imgList[imgIndex]; if (curImgDom.complete) { $('.img-intro').text(imgDescList[imgIndex]); return false; } curImgDom.onload = function () { $('.img-intro').text(imgDescList[imgIndex]); }; }
-
音频播放 1.这里音频设置自动，循环播放，点击图标暂停，播放切换。这里监听了audio的play，canplaythrough（保证音频加载完毕）事件，这里值得注意一点是，audio的play（）方法执行后返回来的promise对象，用来判断是否成功执行（播放），可以根据这个promise控制音乐🎵图标的旋转or停止状态，大致代码如下：
audioDom.addEventListener('canplaythrough', function () { try { // chrome浏览器没有也页面交互（点击，滚动）之前会报错误---Uncaught（in promise）DOMException：play（） //处理方法设置浏览器autoplay-policy---https://blog.csdn.net/super_XYQ/article/details/83026792 var promise = audioDom.play(); if (promise !== undefined) { promise.then(function () { musicCloseDom.classList.add('rotate'); }).catch(function () { musicCloseDom.classList.remove('rotate'); }); } } catch (error) { console.log('error', error); } }, false);

设置Open graph(从浏览器分享到社交网络配置)

代码如下
<!--从chrome分享到微信效果如上--> <meta property="og:type" content="website"> <meta property="og:url" content="https://jackluson.github.io/to-lover-demo/"> <meta property="og:description" content="一个记录“我们在一起走过点点滴滴”的idea"> <meta property="og:title" content="宝贝,感谢你一直的陪伴！"> <meta property="og:image" content="https://jackluson.github.io/to-lover-demo/pic-icon.png"> <meta property="og:image:width" content="140"> <meta property="og:image:height" content="109">

这里用到了python脚本生成艺术二维码
version, level, qr_name = myqr.run( 'https://jackluson.github.io/to-lover-demo/', # 'https://jackluson.github.io/to-lover/', version=1, level='H', picture='pic-icon.png', colorized=True, contrast=1.0, brightness=1.0, save_name='ip_jackLu.png', save_dir=os.getcwd() )
-
还有利用python压缩图片，与剪切音频，避免文件过大
from glob import glob from PIL import Image import pyperclip source_dir = 'origin_images' target_dir = 'images' threshold = 1.5*1024*1024 if not os.path.exists(target_dir): os.makedirs(target_dir) filenames = glob('{}/*.[jp]*'.format(source_dir)) # print(','.join(filenames)) strFileNames = '' for i,filename in enumerate(filenames): # 拼接文件名字符串 strFileNames = strFileNames + '"' + filename +'",' filesize = os.path.getsize(filename) output_filename = filename.replace(source_dir, target_dir) # output_filename = time.strftime("%Y-%m-%d", time.localtime()) + '000' + str(i) + '.png'; print('output_filename:',output_filename) if filesize >= threshold: print(filename) with Image.open(filename) as im: width, height = im.size new_width = width // 2 new_height = int(new_width * height * 1.0 / width) print('adjusted size:', new_width, new_height) resized_im = im.resize((new_width, new_height)) resized_im.save(output_filename) else: with Image.open(filename) as im: im.save(output_filename) # 字符串复制到剪切板 strFileNames = strFileNames.replace(source_dir + '\\', './' + target_dir + '/') print(strFileNames[0:-1]); pyperclip.copy(strFileNames[0:-1]); spam = pyperclip.paste() # 剪切音频 from pydub import AudioSegment file_name = "./media/zui-mei-qing-lv.mp3" sound = AudioSegment.from_mp3(file_name) start_time = "0:08" stop_time = "1:37" print ("time:",start_time,"~",stop_time) start_time = (int(start_time.split(':')[0])*60+int(start_time.split(':')[1]))*1000 stop_time = (int(stop_time.split(':')[0])*60+int(stop_time.split(':')[1]))*1000 print("ms:",start_time,"~",stop_time) word = sound[start_time:stop_time] # save_name = "xiaye-and-anlian.mp3-"+file_name[6:] save_name = "./media/zui-mei-qing-lv-cut.mp3" print (save_name) word.export(save_name, format="mp3",tags={'artist': 'AppLeU0', 'album': save_name[:-4]})
最后其他不啰嗦了,搭建在gitpage上,图片加载应该很慢,有问题多谢能够指出！
