"Supercharged.JavaScript.Graphics(第1版)" 是一本专为已具备良好JavaScript基础的开发者准备的图书,旨在探索超越简单悬停效果和依赖库如jQuery的动画功能的图形编程。书中深入介绍了如何利用JavaScript实现高性能的图形处理,包括DOM操作、Canvas元素、视频游戏开发、数学在创意图形和动画中的应用、使用Google可视化API和图表工具展示数据、有效使用jQuery及开发图形插件,以及利用jQuery Mobile创建适用于移动设备的富图形Web应用。此外,还涉及了使用PhoneGap将Web应用转化为原生Android应用。 在JavaScript Graphics 3d这个标签下,本书特别强调了JavaScript在3D图形方面的潜力。通过Canvas元素,开发者可以访问到额外的图形处理能力,这使得JavaScript成为与Adobe Flash等插件竞争的可行选择。Canvas是HTML5的一个重要组成部分,它允许动态和脚本化的图形渲染,为网页带来丰富的交互性和动态内容。 部分内容提到了作者Raffaele Cecco的经历,他作为一名资深游戏开发者,对JavaScript在图形编程中的表现感到惊喜。书中涵盖了代码复用和优化、继承技术、性能提升技巧等内容,鼓励读者实验和享受JavaScript图形编程的乐趣。这本书节奏快速,旨在为读者提供各种图形技术的全面入门,激发他们进一步探索这个领域的兴趣。 通过阅读这本书,读者将能够利用JavaScript的强大力量创建引人入胜的Web图形,包括制作视频游戏、构建数据可视化应用,并掌握在移动设备上运行的图形丰富Web应用的开发方法。同时,对于希望将Web应用转化为原生移动应用的开发者,PhoneGap的使用方法也是一大亮点。这本书是JavaScript图形编程领域的一份宝贵的资源,适合想要提升技能的开发者参考学习。

feScore - EPA Fuel Economy Score (负1 = Not available) fuelCost08 - annual fuel cost for fuelType1 ($) (7) fuelCostA08 - annual fuel cost for fuelType2 ($) (7) fuelType - fuel type with fuelType1 and fuelType2 (if applicable) fuelType1 - fuel type 1. For single fuel vehicles, this will be the only fuel. For dual fuel vehicles, this will be the conventional fuel. fuelType2 - fuel type 2. For dual fuel vehicles, this will be the alternative fuel (e.g. E85, Electricity, CNG, LPG). For single fuel vehicles, this field is not used ghgScore - EPA GHG score (负1 = Not available) ghgScoreA - EPA GHG score for dual fuel vehicle running on the alternative fuel (负1 = Not available) guzzler- if G or T, this vehicle is subject to the gas guzzler tax highway08 - highway MPG for fuelType1 (2) highway08U - unrounded highway MPG for fuelType1 (2), (3) highwayA08 - highway MPG for fuelType2 (2) highwayA08U - unrounded highway MPG for fuelType2 (2),(3) highwayCD - highway gasoline consumption (gallons/100miles) in charge depleting mode (4) highwayE - highway electricity consumption in kwhrs/100 miles highwayUF - EPA highway utility factor (share of electricity) for PHEV hlv - hatchback luggage volume (cubic feet) (8) hpv - hatchback passenger volume (cubic feet) (8) id - vehicle record id lv2 - 2 door luggage volume (cubic feet) (8) lv4 - 4 door luggage volume (cubic feet) (8) make - manufacturer (division) mfrCode - 3character manufacturer code model - model name (carline) mpgData - has Your MPG data; see yourMpgVehicle and yourMpgDriverVehicle phevBlended - if true, this vehicle operates on a blend of gasoline and electricity in charge depleting mode pv2 - 2door passenger volume (cubic feet) (8) pv4 - 4door passenger volume (cubic feet) (8) rangeA - EPA range for fuelType2 rangeCityA - EPA city range for fuelType2 rangeHwyA - EPA highway range for fuelType2 trans_dscr - transmission descriptor; see http://www.fueleconomy.gov/feg/findacarhelp.shtml#trany trany - transmission UCity - unadjusted city MPG for fuelType1; see the description of the EPA test procedures UCityA - unadjusted city MPG for fuelType2; see the description of the EPA test procedures UHighway - unadjusted highway MPG for fuelType1; see the description of the EPA test procedures UHighwayA - unadjusted highway MPG for fuelType2; see the description of the EPA test procedures VClass - EPA vehicle size class year - model year youSaveSpend - you save/spend over 5 years compared to an average car ($). Savings are positive; a greater amount spent yields a negative number. For dual fuel vehicles, this is the cost savings for gasoline. sCharger - if S, this vehicle is supercharged tCharger - if T, this vehicle is turbocharged翻译
