- 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)
