Mix Training Shows How to Control PArticle Emission Using TExtures in Side Effects Houdini.
Mix Traning’s Alvaro Castaneda shows how you can control particles and particle emission in Houdini by using a texture. Working with particles affords a few methods for controlling them, forces, fields, and code are some of the ways. You could also regulate the particle emissions using a texture map.
Although, in Side Effects Houdini, it might not work exactly how you would expect. Castaneda walks through one example that uses an image to control various aspects of the particle systems used.
Putting Houdini Particles Into Practice
Particles and particle simulation is a widely covered facet of any DCC. Here are a few tutorials for Side Effects Houdini that can help you get started with learning more.
3D Artist Bogdan Lazar shows how to make a realistic sun complete with solar flares. The tutorial covers a bit of VEX coding, some vector calculus, VDB Volumes, particle simulations, magnetic fields and much more. https://lesterbanks.com/2017/04/create-realistic-sun-flares-houdini/
Mix Traning’s Alvaro Castaneda shows how you can create a disintegration effect with any object in Houdini. Alvaro breaks the system down into three components: First showing how you can remove the geometry from the original model when needed. Secondly, breaking up the geometry into parts. Finally, having those parts emit Houdini particles to complete the effect. https://lesterbanks.com/2017/03/disintegrate-geometry-houdini/
Emit Particles from Video
Houdini Artist Mark Fancher demonstrates a technique that lets you drive FLIP Fluids and particles using a piece of digital video. The whole system is a procedural driven by motion analysis of video itself. https://lesterbanks.com/2017/08/video-drives-fluid-simulations-houdini/
Particles to Rigid Bodies and Back Again
Tim van Helsdingen and Andrew both show how you can emit particles and then have them work within a bullet physics system. For example, you can turn particles into bullet rigid bodies once meeting a condition. https://lesterbanks.com/2016/08/easily-turn-houdini-particles-to-bullet-rigid-bodies/
