3dgarage.com), you??™ll see more examples. But you can take even the simple
particles created here a step further by setting up a cool surface for them. And once the
surfaces are set, you can still go back and make changes to the particle emitter and interactively
change the parameters with more vibration, less wind, or faster velocity for cooler
effects. For now, these particles are cool, but what good are they? If you render a frame,
you??™ll see nothing. If there were objects loaded in the scene, you??™d only see those render,
and you still wouldn??™t see the particles. That??™s because you created an HV Emitter earlier
in the chapter, meaning you must apply HyperVoxels to them to make them visible.
Another type of emitter you could add is a Partigon emitter. It works similarly to an HV
Emitter, except that it generates single-point polygons that will show during a render.
These are great for tiny sparks, water sprays, or even stars.
Three surfacing options are available for HyperVoxels: Surface mode, for solid blobby
objects;Volume mode, for 3D clouds and smoke; and Sprite mode. Sprites are like 2D surface
maps that emulate the effect of a HyperVoxel when it??™s applied to a 3D volume.
