Open question to 3D artists
Hello everyone.
I’m currently in my 3rd year at university, studying for a BA (Hons) is TV and Media Practice. My dissertation subject is about the evolution of computer visual effects over the last 30 years and I just came across something which made me curious. Homour me, if you will. How many of you know what I’m talking about if I mention the following seven attributes?
(1) initial position,
(2) initial velocity (both speed and direction),
(3) initial size,
(4) initial colour,
(5) initial transparency,
(6) shape,
(7) lifetime.Thanks for your time.

Question is a bit open ended. Are all of the attributes supposed to describe one thing? If so I would say it’s a description of a particle at birth.

There are several instances in which these terms could relevant, in my opinion. I have certainly come across all of them in one form or another.
I’m only half the thing I say I am, the other half are me.

Hi guys. Thanks very much for your answers.
What it’s all about is, during my research I came across a paper written in 1983 by a fellow named William Reeves, who describes in great detail how he created the Genesis Effect animation for Star Trek: The Wrath of Khan, and says all the particles used had those 7 attributes. And bearing in mind this paper was written 28 years ago I found it surprising to see attributes I recognise myself from Blender and After Effects being talked about back then in the days of the ZX Spectrum.
So now I can add into my disseration or literature review that the terms used by Reeves back then are still in use today, and I can justify using the paper in my research.
