A Particle system for OpalVision

If you are reading this as a post, rather than a text file included
with an animation, you can find this animation in the file PAP-DEMO.LHA
on Portal, Aminet and other fine BBSs.

Thank for you downloading the Part And Particle demo anim! I've
been hard at work on Part And Particle for several months now, and I'm
proud to say it's ready to roll out! Originally, Part And Particle was
to be a simple particle system that allowed anyone to create the sparkley
(is that a word?) particle effects I made by hand using an paint program.
But with all the features that have been added since it's inception, Part
And Particle is far more than just a simple particle utility.
Part And Particle is modular. You can add as many modules to a Part
And Particle project as you like. Each module can have up to 200 new
particles generated per frame (The demo anim only has about 20 per frame).
A "module" is an element in the animation. For example, the bubbles
rising from below in the animation are 3 of the modules. 3 because there
are actually 3 different sizes of bubbles in the animation. The particles
eminating from a "robotic probe" is another module. Each module in Part
And Particle has it's own gravity, wind and behaviour settings.
In addition to being modular within a project, you can layer multiple
projects for a single animation. This demo anim was made up of 4 projects.
The reason for this is only one "source" of particles can be specifies per
project, so layering allows multiple sources. The "probes" in the
animation define 3 of the sources. Each of the "probes" have particles and
lens-flare modules eminating from them.
That's right. Part And Particle does lens-flare too. Not true lens-
flare, as you would need a 3D system for that, but a very nice effect
indeed. You can have your lens-flares "flicker" or vary in intensity from
frame to frame simply by turning on an option. This is great for "welding"
effects. It was used in this demo anim as well.
ABOUT THE ANIMATION:
The 32-colour anim included in this archive is busy to say the least.
I wanted to cram as many feature elements in the anim as I could. I also
wanted to avoid making the anim look too cluttered. Well, I think I might
have crossed that border a bit. But this anim wasn't really intended to
be fine art, it's intended to demonstrate Part And Particle's features.
The lower portion of the screen has bubbles rising from below the
screen. The "wiggle" of the bubbles was made simply by turning on the
horizontal wiggle. I gave the bubbles a short lifespan so they don't
interfere too much with the action above.
The box that pops up with the "FOLLOW ME" label demonstrates the
"CHASE" feature. Although it's very quick, you'll notice the particles
getting sucked towards the red light when it turns on. Also notice that
I elected not to have the "FOLLOW ME" light effect the bubbles.
PART AND PARTICLE FEATURES:
* Interactive AmigaGuide documentation
* Easy to use graphic interface that takes full advantage of OpalPaint
version 2.3's new programmable requestors.
* Add as many modules to a project as you like. Each module has it's
own independant gravity, wind and behaviour settings.
* Layer up to 15 project for one animation.
* From up to 200 new particles generated per module to a new particle
once every few frames.
* Particles are a series of "brush" images that act like AnimBrushes.
You can have them play once then die, or loop, or play randomly or
just use the first frame as a static particle. Create your own
particles and have them look like anythiny you desire!
* Circular, hexagonal, septagonal, octagonal, nonagonal or decagonal
lens-flares. Create your own "lenses" and tell Part And Particle
where each lens-notch is and what it looks like.
* Gravity can pull up, down, towards the center of the screen or away
from the center of the screen. Using "Chase," you can have gravity
pull towards any part of the screen, and move around in an animation!
* Wind can blow left, right, in a clockwise or counter-clockwise
whirlwind.
* Particles can eminate from a dynamic (movable) coordinate in your
animation, or from any side of the screen (example: Rain falling from
the top of the screen).
* Particles can be thrown at any strength, in any of the 8 "joystick"
directions or randomly thrown in any direction.
* Particles can be told to "wander aimlessly" in their travels. The
effect is similar to flying insects.
* Particles can have motion blur.
* Particles can wiggle horizontally and/or vertically.
* Particles can cast a shadow.
* Particles can be told to bounce off the sides of your screen, or
"wraparound" to the opposite side of the screen.
* You can use a text-editor if you like to tweak projects or copy "module"
information from project to project. If you're shy around text editors,
you do not need to use them.
* Part And Particle is reasonably fast. The complexity of your projects
and the speed of your Amiga will influence how fast part and particle is.
For this demo animation, my 25Mhz '030 Amiga created a new frame every
5 minutes in it's most complex phase. In the simpler parts of the
project, the same machine created 2-3 frames per minute.
WHAT PART AND PARTICLE REQUIRES:
To run Part And Particle, you will need:
* About 5 megs of ram. The more memory the better.
* OpalPaint v2.3 or higher
* Arexx (or Workbench v2.0 or higher)
