美国NewTek公司开发的LightWave 3D是一款高性价比的三维动画制作软件,它的功能非常强大,是业界为数不多的几款重量级三维动画软件之一。LightWave 3D从有趣的AMIGA开始,发展到今天的11版本,已经成为一款功能非常强大的三维动画软件,支持论坛WINDOWS，MAC OS 32位，64位。被广泛应用在电影、电视、游戏、网页、广告、印刷、动画等各领域。它的操作简便，易学易用，在生物建模和角色动画方面功能异常强大；基于光线跟踪、光能传递等技术的渲染模块，令它的渲染品质几尽完美。它以其优异性能倍受影视特效制作公司和游戏开发商的青睐。当年火爆一时的好莱坞大片《TITANIC》中细致逼真的船体模型、《RED PLANET》中的电影特效以及《恐龙危机2》、《生化危机-代号维洛尼卡》等许多经典游戏均由LightWave 3D开发制作完成。
SimplyLightWave Camera Tracking and Smoke Effects
In this interesting project with Jacobo Barriero we create realistic smoke with sprite particles in Lightwave and use a clip mask to project an image onto simple geometry in 3D space. We also look at finding the camera information from images in Lightwave and SynthEyes. We start off in the first part with creating the image mask in Photoshop from a picture of an oil refinery. Here we cover some of the fundamentals of alpha based transparency, and you will learn some excellent production methods which can save you a lot of time on modeling and texturing in Lightwave. In the second part we set up a camera background image in Lightwave and create some very basic geometry onto which we project the image mask. In order to do this accurately and get a good result we retrieve the camera information from our original image in Lightwave and in SynthEyes camera tracker for a more precise result. You don’t need SynthEyes to follow along with this project but it’s used to demonstrate better accuracy when obtaining camera information from images where it’s unknown. This method of image projection allows us to take a 2D image and use it on a 3D model which we can pan a camera around in 3D space. From here we move on to creating a realistic looking smoke plumes with Lightwave’s particle system. We work with sprites covering the simulation process and shading for particles with turbulence and noise. Finally we finish this off by bringing the different elements together and creating a simple animation. For this we set up render passes and the rendered frames can then be composited together in a post application like After Effects. We do not cover the After Effects portion in this tutorial and finish off in Lightwave. This tutorial will give a very broad overview of some of the things Lightwave is capable of.
