1494.0. "Fantastic Animation!" by LEDS::ACCIARDI (I Blit, therefore I am...) Wed Jun 22 1988 14:50

    
    I downloaded a fantastic HAM animation called 'GhostPool' that was
    written up in INFO magazine.
    
    There are 154 seperate frames of interlaced HAM images generated
    by DBW_Render (Hi Dave!).  Uncompressed, there are over 6 Megs worth
    of images.  The frames are compressed and animated using Byte-by-Byte's
    PD Movie! software.  Compressed, the whole animation fits into 437
    KBytes.
    
    However, there are digitized sounds, too, so you really need a 1
    meg Amiga to play it.
    
    This was a 1 hour download at 1200 baud using WXmodem (from Plink),
    so figure on 2 hours with Vanilla Xmodem or 4 hours with Kermit.
    
    Any brave souls want to download it?  If so, I'll place it in my
    account.  You'll also need the latest Movie! software, which I'll
    include.

    PLUG:  DBW_Render seems to generate the most realistic looking scenes
    	   of all the ray tracers available.  This isn't just my opinion,
           but the general consensus of ray tracing addicts on Plink.

1494.1	Post it Ed! Please!	ELWOOD::WHERRY	Software Commandoes Ltd.	`Wed Jun 22 1988 15:07`	3
	Please do! brad
1494.2	Please Do.	MTBLUE::SEELEY_BOB		`Wed Jun 22 1988 16:25`	7
	I'm brave also. Please post it's location. I read about this one a few weeks ago and I was hoping that someone would be nice enough to present it to all of the graphics junkies that are looking for another 'fix' in this notesfile :-) Please Do.
1494.3	Worth every second!	KYOA::WEGER	Bruce Weger	`Wed Jun 22 1988 18:00`	8
	Oh Yeah, I saw this at a recent user group meeting. I was really impressed. The sound includes a digitized voice and ball clicking/pocket clunking. It's definitely worth the D/L time. Thanx -bw
1494.4	I haven't given up on this stuff (yet)	COOKIE::WECKER	Good old 6844A7B7A5000965D0	`Wed Jun 22 1988 20:41`	8
	I know this subject is somewhat off limits for me but.... just in case you're interested I've just completed a new "micro" ray tracer with better image quality than DBW_Render and if I'm able to implement a new algorithm I found, it could run up to 100 times faster. Now don't start drooling..... dave
1494.5	another vote for this animation	LEMAN::BLANC	Phil Lausanne-CH 23-JUN-1988 09:35	`Thu Jun 23 1988 07:43`	9
	re: .0 Yes please download, (I can download at 9600 baud so....) re: .-1 wouaaaaa...100 times faster.....and better quality for the images........That will be fun... Phil
1494.6	a plea..	LEDS3::ACCIARDI	I Blit, therefore I am...	`Thu Jun 23 1988 12:34`	14
	Here's a request to anyone who may be working on math-intensive software... :^) Please try to implement the new math library that will automatically call the math chip if present. So far, under 1.3, I've only found a few programs that use the AmigaDOS double-precision math library. Sculpt-3D apparently does all of it's math internally. Bummer. By the way, looks like I won't be able to upload this stuff until Friday 6/24 or later. I tried last night, but there was a monsoon going on that affected my phone lines. Ed.
1494.7	Look in...	WINNER::JBERNARD	John Bernard YWO/292-2591	`Thu Jun 23 1988 15:35`	10
	I have GhostPool on Amy here at work. I'll upload it today. Check in WINNER""::Disk$User_1:[Bernard.Amiga] I'll upload GhostPool.doc first and then make an archive with all the associated files (GhostPool.arc). If anyone is in the area, stop by and I'll make you a disk... John
1494.8	redirect..	WINNER::JBERNARD	John Bernard YWO/292-2591	`Thu Jun 23 1988 18:00`	6
	Woops.... Make that area [JBERNARD.AMIGA] sorry... john
1494.9	No .ARC yet	EVER11::EKLOF	We're everywhere.	`Sat Jun 25 1988 02:11`	6
	re: .7,.8 When will the .ARC be there? It's not now. Mark
1494.10	Finally... On its way...	WINNER::JBERNARD	John Bernard YWO/292-2591	`Tue Jun 28 1988 23:44`	22
1494.11	Who's "Meg"?	CRISTA::CAPRICCIO	What about pointed sticks?	`Wed Jun 29 1988 03:01`	9
	Re: .0 > However, there are digitized sounds, too, so you really need a 1 > meg Amiga to play it. Does this mean it won't run at all on a 512K machine, or just no sound? Pete
1494.12	512K amiga	REGENT::VAILLETTE		`Wed Jun 29 1988 11:32`	19
	RE: .-1 Interceptor requires at least 512 K bytes. On 512K byte machines, it is recommended that the external drive be disconnected for improved sound. It is recommended that you have 1 megabyte of memory to maximize sound capabilities, as well as to view the demonstration flight in full. I noticed that only about 25% of the demo flight ran when I first booted my disk after seeing the full demo at the store. I don't know exactly what sounds we're missing, but the basic engine roar seemed the same as with more memory. (I didn't have the drive disconnected). I then added the addmem command to the Interceptor startup-sequence to configure my spirit 1.5 meg internal Ram and can now run the full demo and hear all the sounds. Gary
1494.13	oops! "never mind"	REGENT::VAILLETTE		`Wed Jun 29 1988 12:27`	14
	RE: -1 oops! Sorry, I thought I was reading an Interceptor note. Can my reply be deleted or moved to the Interceptor note ? RE: -2 I have 2 meg, so I can't answer your question about 512K, but I downloaded GhostPool last night. Thanks John, great animation. I can hardly wait for John to upload the sound files. Gary
1494.14	All there now..	WINNER::JBERNARD	John Bernard YWO/292-2591	`Wed Jun 29 1988 17:29`	11
	Sound files are now uploaded for Ghostpool. I also uploaded another animation called "Raisin" along with Movie 1.3. There is also am IFF picture file "Samples.pic" that I uploaded that shows a few new fonts I got from a PD disk. Sorry for the delay, but it's been crazy around here the last few days (weeks...months...). John
1494.15	Damn that DRAM	CRISTA::CAPRICCIO	What about pointed sticks?	`Thu Jun 30 1988 01:36`	12
	From GHOSTPOOL.DOC: > Note that there is also a non-interlaced version of GhostPool available, > which will run in a 512K Amiga. > Dr. Gandalf, AKA Eric J Fleischer, MD Anybody out there have this one for us little guys? Pete
1494.16	Non-interlaced ???	PUERTO::ALVAREZ	Miguel,from sunny Puerto Rico	`Thu Jun 30 1988 12:33`	15
	Re. .15 > Note that there is also a non-interlaced version of GhostPool available, > which will run in a 512K Amiga. > > Dr. Gandalf, AKA Eric J Fleischer, MD > Anybody out there have this one for us little guys? > Pete Yea, somebody has it ??? Miguel A.
1494.17		VIDEO::LEIBOW	Michael Leibow	`Fri Jul 01 1988 10:48`	13
	I uploaded ghostpool and tried it. I don't think it is very good at all. I was very unimpressed. It seems like a huge (enormous) waste of time to raytrace all of those frames, when a few icons could have been manipulated from BASIC to produce a "movie" of the same quality. I am not a fan of BASIC, and don't even remember how to program in it, but I'm sure I could implement a ghostpool like animation in less then the time it would take to ray trace one or two frames. --Mike PS: I woke up on the wrong side of the bed this week.
1494.18	how's Raisin?	WJG::GUINEAU		`Fri Jul 01 1988 11:41`	6
	I have to agree with you, Mike. Niether me nor my roomate were impressed at all.. John
1494.19	More to come...	WINNER::JBERNARD	John Bernard YWO/292-2591	`Sat Jul 02 1988 18:50`	13
	Raisin is just "cute", absolutely will not blow your socks off though. I have a couple of other animations I'll upload to my area when I get a chance. One is of the Boing ball crashing through two walls... The other you'll have to see to believe... More in a bit.... got to go... John
1494.20	Ain't It Awful!	DRUMS::FEHSKENS		`Tue Jul 05 1988 17:01`	7
	Actually, it speaks rather highly of the Amiga that we have become so jaded that animations that a few years ago would have been considered science fiction now rate a "ho hum" response. len.
1494.21	Did anyone REALLY want speed?	COOKIE::WECKER	Good old 6844A7B7A5000965D0	`Sat Jul 09 1988 18:11`	12
	re: .4 Well... I told you not to drool. Sure enough, the new algorithm is "100 times faster than a standard ray-tracer"... unfortunatly their definition of a "standard ray-tracer" is a ray-tracer without any extents. All my ray-tracers have oct-tree extents and guess what? They're already 130 times faster than a "standard ray-tracer"!!! Oh well.. back to the drawing board. (Don't worry... I'm not giving up yet!) dave
1494.22	extents?	SAUTER::SAUTER	John Sauter	`Sun Jul 10 1988 17:00`	2
	re: .21--What are "extents"? John Sauter
1494.23	Extents	BARDIC::RAVAN		`Mon Jul 11 1988 17:02`	8
	"Extents" are bounding volumes defined around an object by the software to allow a quick check for determining whether or not a given light ray might have hit it. One of the attributes of extents are how tightly they cover the original object which determines how many times the bounding volume check says "yes, go do the expensive intersection check", but then the expensive check ends up saying there was no hit after all. -jim
1494.24	More Animations and Tools	WINNER::JBERNARD	John Bernard YWO/292-2591	`Mon Jul 25 1988 15:33`	49
	Since this seemed like a likely place to post this... I have uploaded the following files to WINNER""::DISK$USER_1:[JBERNARD.AMIGA]. DISPLAY.ARC Display is a replacement for ShowAnim and will play animations DISPLAY.DOC in HASH and ANIM formats. It supports the -C and -L modes of anim files. In addition, the user may change the playback speed, freeze frame, and single step through the animation as it is playing. I have had very good luck with this utility showing animations I could not play previously without rebooting with a "normal" workbench. Display will not show "movie" format animations, so it looks like the animation players you need in your toolbox are Movie and Display... Display will also show IFF picture files. I extracted the .doc file for further info.... Berserk.arc This animation is an update to Leo's original, using a couple new utilities on the market. I downloaded this last night from PLINK. CUDA.arc This is an animation of a shipwreck with barracuda swimming by. Nicely done animation. STCREW.arc A nice picture of Capt. Picard and Yar, all done freehand. Downloaded from PLINK. TUNAJune.txt News and Rumors text file. Select A startup-sequence command utility. This program allows you to Select a startup script from several possible choices. Usage: SELECT NORMAL-BOOT BACKUP-BOOT VSCREEN-BOOT [etc..] [etc..] You would put the above in startup-sequence and a requestor would appear asking you to click on one of the included scripts. This would be handy if you had several environments that you normally used. Enjoy, John
1494.25	BoingThrows??	KYOA::WEGER	Bruce Weger	`Mon Jul 25 1988 18:37`	5
	While we're on the subject of animations, does anyone have a copy of "BoingThrows" squirreled away somewhere on the net. If you haven't seen it, its a guy (robot?) shooting baskets. Nice. It's supposed to be on one of the Fish disks, but I can't locate it on the net where the other Fish disks are.
