Create cinematic 2D and / or 3D shockwaves to match your favourite space movies.
In this video, I talk you through how to create a planar shockwave (as first seen in Star Trek VI: the Undiscovered Country when the Klingon moon of Praxis explodes). The opening of that movie starts with a cataclysmic event which results in two shockwaves traveling through space. It's an awesome opening scene and the VFX was reused in the Stargate movie and the Star Wars Special Editions. While exploding rings may not be scientifically likely, they do look pretty cool, but every tutorial I've seen on the topic has stuck to the 2D method. It turns out it is possible and quite simple to produce a 3D expanding ring using CC Particle World.
I cover both the 2D version, which uses a combination of Fractal Noise, Linear Wipes and Polar Coordinates to get the right look. Then I go on to use the included CC Particle World to generate a shockwave in an entirely different way.

![VFX History: Slit Scan
How did 2001: A Space Odyssey, Star Wars, Doctor Who and Star Trek: The Next Generation create mind-bending visuals decades before CGI?
The secret is Slitscan, a terrifyingly complex technique that literally turns time into space.
In this deep dive into VFX history, I explore the origins of the Slitscan technique. From its humble beginnings in 19th-century strip photography used for horse racing and mapping, to the genius of John Whitney and Douglas Trumbull, we look at how a mechanical slit, a long-exposure camera, and patience created the most iconic trippy visuals in cinema.
Ill cover:
- The Stargate Sequence from 2001 imagined by Stanley Kubrick and Arthur C Clarke, then made real by Doug Trumbull.
- How Bernard Lodge adapted both the technique and a Rostrum camera to create Doctors Whos title sequence.
- John Dykstras method for the jump to hyperspeed for Star Wars.
- ILMs John Knoll pushed the concept even further, creating a three dimensional version to stretch the Enterpise and then also created the famouns look of warp speed, with its rainbow stars.
*🎁 Bonus Section*
Then, just to torture myself, I recreated the Slitscan process (or is it Slit Scan?) inside Adobe After Effects, using the echo effect and essential graphics.
