I'm considering getting an Amiga for the sake of interactive multimedia
applications and I have a bunch of introductory-type questions. I'm not
even sure exactly what to ask, so if somebody just wants to send me
random musings and comments on related topics I'd appreciate that too.
Some questions:
I've seen a Mandala installation, but I couldn't tell and would like
to know:
- what does mandala actually provide in terms of image parsing?
- does Mandala provide its own programming language? A good one?
- are there hooks for accessing mandala from other languages?
- how can I get more info? (email? 800 number?)
- if I can do some image hacking myself, how easy is it to access
image data from frame grabbers from other Amiga language
implementations? (I'm not interested in the video output...)
How cheaply can I get a setup with
- a video capture board that grabs at least one (possibly very low res)
frame per second.
- an amiga powerful enough to support the board, some modest crunching
on the images, MIDI output, and control of local sound.
I've seen HMSL - the FORTH-based language for (among other things)
generating MIDI events and local sound (available from Frog Peak Music
in Oakland, CA). What other systems/languages would people recommend
for projects with various kinds of inputs (video input, digitized
sound input, switches hacked into the ports) and only sound output
(animation etc. is not necessary at all).
Thanks for any information you can provide! (email would be best...)

I'm wondering some of the same things, although my multimedia experience is virtually nil. Maybe it would liven up this list, as well! Thanks, Scott Barber barber@jazz.concert.net

Here's some information that was posted a while back. ------------------------------------- Mandala is now available as a separate software package for the Amiga at a price of $495. What is Mandala? It, combined with an Amiga and a Live! board will allow you to: 1) Aim the camera at a person 2) It will take an image of the person and put it into the computer. It then appears as an image in the monitor that can interact with everything going on in the screen. It comes with its own authoring software designed for it. For info on finding the Live board call MicroPace at (217) 356-1884 and for info on Mandala itself call (416) 340-9290. Also, if you are interested in being a Mandala developer you can contact Fred Holland at holland@cbmvax.commodore.com. ------------(end of repost)------------ You may also want to look at Cyberscape, available from Tensor Productions. It also uses the Live! to do very similar things. It's also cheaper ($250.00).

(I'm not interested in the video output...) The Live! digitizer comes with a reasonably well documented library (Live.library) of functions. Or you could talk to the hardware directly. Sunrize's Perfect Vision and Progressive Peripheral's FrameGrabber are more oriented for one-shot grabs. They both come with code examples. >How cheaply can I get a setup with > - a video capture board that grabs at least one (possibly very low res) > frame per second. The Live! board can grab 32 color 356x240 images at a rate of about 10-12 frames per second. You can either grab a single image, or "record" incoming video into an ANIM or RIFF format file, depending on which software you are using. The Live! card for the 2000 costs in the neighborhood of $350.00. I'd recommend that if you were to purchase one, that you buy Invision Plus, a software package that greatly expands the Live's capabilities. Since the Live! uses your machine's memory for captures, I'd recommend at least 3 meg of memory. This will give you the ability to grab about 5 seconds of video in 356x480 mode. Oh, buy a decent sized HD to store your captures. Some of mine are over 2 meg in size. The Perfect Vision hardware can grab a decent 320x200 16 color image (grayscale) in 1/30 of a second. I'm fuzzy on the Framegrabber, but I'm pretty certain that it can grab a 320x200 8bit image in the same amount of time. > - an amiga powerful enough to support the board, some modest crunching > on the images, MIDI output, and control of local sound. Unfortunately, the Live!2000 card will only work on a ZorroII bus (someone please correct me if I'm wrong!). However, it works fine with accelerated systems. I'd recommend that you buy a 2000, simply because the Live!2000 card has configurable inputs; you can either have two video inputs with/without passthrough, or it will accept an RGB input (separate inputs for red, green and blue guns). I'm using mine on a plain-jane 2000. Works great. >What other systems/languages would people recommend >for projects with various kinds of inputs (video input, digitized >sound input, switches hacked into the ports) and only sound output I'm severely biased, but it's based on experience with trying to get other systems to work in a video enviroment. The Amiga is simply the best, most cost-effective system for multimedia production available currently. Apple is slowly catching up, but they still have a ways to go. >Thanks for any information you can provide!
