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.
