Tuesday BryceTalk —Terrain Mania! June 22, 1999
part 4

AuntiAlias: before we go there, Klaus

Klaus, you want to give us a basic rundown for using KPT/Photoshop plug in filters in the Terrain Editor?

ccasady: okay, which first?

AuntiAlias: basic... then on to fractals and tiling

basic filters I mean

MetaKlaus: Okay, many of you have encountered that you

can use any plugin (ok, most of them...)

AuntiAlias: (and KPT Gradient Designer comes with Bryce!)

MetaKlaus: in both the Picture window and the terrain editor!

Rosy: I saw it in Picture

MetaKlaus: So, you can for instance twirl a terrain

ccasady: (great for tornados, !)

Rosy: LOL

MetaKlaus: (it's a little coarse afterwards, so smooth it a little bit!))

So, a few tips...

george: (I'm going to ask a question in the lobby for anyone still interested in the terrain questions and pgm)

MetaKlaus: KPT5 fraxplorer:

AuntiAlias: ? Klaus, where do you access the filters in the Terrain Editor?

Rosy: yeah...where

MetaKlaus: It's in the filter tab (the one nobody used before ;-)

ccasady: Klause: I learned something from Ales at Bryce Camp about this: The KPT filters are suported in 10 bit here.

4096 grays I think

AuntiAlias: to access filters themselves, look at pop-up menu to the right, just above where it says "Apply"

MetaKlaus: there is not more space here... okkay, it's a little popup above Apply...

There you can choose your plugin folder (and B4 mounts the filter on the fly!)

If you would like to use Fraxplorer to create colored terrains (matching color and landscape)

MetaKlaus: then use distance estimate for the terrain grayscale

jonjon: Yer wot?

MetaKlaus: and use a *very* slow b/w gradient

You don't really see the terrain form in KPT (terrains are quite sensitive)

it looks like the whole terrain is more or less white

But if you apply the filter you get nice runded mountains afterwards...

jonjon: Sorry but wot's "distance estimate? "

MetaKlaus: As always after applying 8-bit filter: smooth a little bit afterwards

distance estimate is the fractal style!

AuntiAlias: ?

jonjon: in kpt oh right! sorry

MetaKlaus: Autie?

AuntiAlias: Klaus: Is distance estimate fractal style the same thing as, say, in Gradient Designer choosing the Mode that is grayscale mapburst?

MetaKlaus: No. Distance estimate is a certain method to find the value in a potential fractal

If you know what I mean ;-)

math stuff

AuntiAlias: oh yeah. sure! uh huh!! :::rollign eyes::::

MetaKlaus: Chris, would you like to talk about the new fractal styles?

This is just to cool to miss!

ccasady: sure

I'd like to talk about how to use these fabulous new mathematics:

The new Fractal Noise Models (do we have a better name for these?)

MetaKlaus: no

ccasady: okay

They are hiding uinder a small grey triagle next to the word Fractal <I in the Elevation palett.

MetaKlaus: we always hide our cool features ;-)

ccasady: I call them: "The new ractal terrain Models.

or: "Ken Musgraves new fractals"

First I want to say something about how to shop for good terrains in here,

... and then I want to describe the proper sequence for obtaining a tiled grid of many terrains that all match perfectly together.

MetaKlaus: stuff that get's the files biiiig

george: I have to go, but I have still a question for Klaus....may I ask it? (answer to my question would be a simple yes/no)

ccasady: Tiling??? yes! These terrins do "tile", and I can do the tile, baby.

ccasady: sure George

mmurphy: Hey all!

ccasady: go for it George

george: Does every point in the martix have a corresponding number from 0-65535 in the PGM format?

jonjon: drat, gotta go thanks a lot guys. Been excellent.

george: (the 1024x1024 for instance)

MetaKlaus: yes. Look at the format, and if you can read, you understand it.

PJF88: lol

george: Okay. Just checking. Thanks! THis is a log to keep!!!

ccasady: (Hi Martin, wer'e in a formal TERRAIN chat, me and Klause Busse)

MetaKlaus: If there's interest, we post the specs!

Calyxa: yes, please!

boru: ja!

Betty: yes here too

ccasady: Back to new Fractals?

AuntiAlias: That'll be taken up at another time (specs for terrains)... back to TILING, TileNut!!

ccasady: Shopping:

Shoping for good terrains...

Infinite terrains live here.

ccasady: They are random, they come up different every time.

Do you all know where to find these? First off?

Androo...: yep

ccasady: They are hiding uinder a small grey triagle next to the word Fractal <I in the Elevation palett.

Good.

Rosy: triangle next to Fractas

ccasady: yes.

You may notice that you wait for these terrains.

The computer must think hard! They are so difficult to make!

About a half a minute on my machine.

I usualy make these at 512K resolution.

AuntiAlias: !

ccasady: yes?

AuntiAlias: Clarification: First select fractal type, THEN click the Fractal button

ccasady: right, thank you.

Rosy: oh nice

ccasady: you pick the type out of the list... Then hit "Fractal"

there are 27 some types

(my favorites are Ridged Multifractal, Slickrock, Warped Zorch, and Planet-X)

It often takes 30 to 40 seconds each, and then I don't like the Terrain. : (

MetaKlaus: may I introduce a tip?

Rosy: LOL

ccasady: Notice they are much faster to generate if you lower your terrain resolution to 128K resolution.

geosteve: Has anyone had difficulty with terrains changing properties when you start to do anything regarding animation in Bryce 4 on Windows.

AuntiAlias: we'll take that up in Q & A,, geosteve! right now, Chris is sharing a tip/technique! : )

ccasady: Hey! 128K, click! click! click! I see new and exciting fractals each time, very fast, ....no waiting!

Androo...: ?

ccasady: so I click and see many different kinds, most of them no good....

But wait! Look! I love that one, It's beautiful!

aw, but it's only 128K. I can't use it; it's too low a rezolution.

Rosy: bummer

ccasady: You can fix it.

Here's what you do.

bring up that list of fractal types....

Look way down near the bottom

Turn off Random Extent, Position, & Character.

Now when you regenerate a terrain it will regerate the same Terrain each time.

Rosy: wow

ccasady: Just go in to Grid and up rez your tarrin to 512 or 1024 and click "Fractal" again.

PJF88: Oooooh

boru: Great

ccasady: So this make shopping easier,

Rosy: wow

AuntiAlias: <and the crowd goes wild!>

ccasady: I admit, it's a paint to scroll way down there 3 times to turn those off

But that's how you repeat a type you liked.

AuntiAlias: (takes less than 30 seconds, tho, I'd imagine!)

MetaKlaus: would anybody prefer to have only a few fractal types?

PJF88: no way

Rosy: nope

KathG: no way :)

ccasady: no, we like choices.

george: bye! it's been fascinating!

CBXTX: Nada

ccasady: Now...! .... you can tile them.. : )

mmurphy: more, more more!

ccasady: want to hear the steps for tiling these?

Rosy: yeah!

KathG: yes please

Androo...: yup

mmurphy: yes

PJF88: maybe, OK yeah!

AuntiAlias: <the crowd goes wild AGAIN!>

ccasady: used alone they are problematic

because they don't go black at the edges.

that's where tiling is intended to be used

here goes:

Once you found a random fractal terrain you like, turn off all three random controls; Extent, Position, & Character and boost your terrain resolution (Grid) up to 256, maybe 512, then leave the Terrain Editor.

Back in Bryce's work window now, copy the terrain with a Duplicate command and move it either north, south, west or east it doesn't matter as long as it matches what we set in the next step.

AuntiAlias: leave check OK? or leave cancel?

ccasady: yes, check okay

AuntiAlias: : )

boru: ?


 

 

ccasady: Okay, now you have two terrains, papa and son

Morpheus: gotta go

Rosy: lol

ccasady: Boru???

KathG: lol

boru: Which way's north?

Morpheus: is this going to be logged?

PJF88: pole star

AuntiAlias: yes, MOrpheus! as they ALL are!

Morpheus: okay thanks

ccasady: north is always 'up'

MetaKlaus: lol

AuntiAlias: Also, there was a question back there from Androo... when you're ready to take another question, Chris, let 'im know! : )

ccasady: west if Left, you all know that.

boru: up cursor arrow or page up?

Sky Pilot: From Top view

ccasady: yes, sorry, Androo?

Androo...: I'm ok ta :)

ccasady: k

so Papa and son....

Now enter the Tarrain Editor for this new Terrain.

You'll see it's the same terrain, also at 256 or 512 or whatever you made it.

Go to the pop up triagle where the names & random switches are (Just right of "Fractal" ) and scroll down to the VERY bottom.

You'll see; "Tile North, Tile South, Tile West, Tile East".

Chose the one to match the position of this duplicate in relation to it's cloned "parent".

if you moved the terrain north (up) then choose Tile North

BTW....

I go to the top view (hit #2 on keyboard) to move these terrains e,w,n, or s

Rosy: ah more clear that way

ccasady: Yup, Oaky, your in the TE of terrain #2....

Now a single click on the "Fractal" generator button with generate a tiled mate that will perfectly fit north of the first terrain.

You can continue this process forever going in any direction, even changing direction, as long as you are generating terrain adjacent to the previous one.

RabbleRouser: basically the fractal is already tiled. By copying it and saying to tile north, etc, you are picking up the character of the "infinite" fractal, right?

ccasady: right.

mmurphy: ahhhhhhhhh

AuntiAlias: whee!!

RabbleRouser: score!

Rosy: wow

ccasady: it somehow knows this infinite pattern and your just taking tiles of it

Have fun, and don't get lost.

AuntiAlias: cool!!!

mmurphy: now that is cool

KathG: thats great

AuntiAlias: if you're done discussing tiling, Chris, there's a question that was asked earlier...

ccasady: as for the real positioning of these Terrain in the Bryce universe? Youl have to position them by hand.

okay: Questions???

AuntiAlias: this was from geosteve, earlier: geosteve: Has anyone had difficulty with terrains changing properties when you start to do anything regarding animation in Bryce 4 on Windows.

Anyone who wants to take a stab, please type !

MetaKlaus: accidently you may animate them...

ccasady: Gosh, I have very little exoerience with that.

RabbleRouser: ?

MetaKlaus: but actually I haven't heard of real problems...

Rabble?

PJF88: Is this another keyframes problem?

AuntiAlias: ! It may be that indavertantly you assigned a keyframe, and that's why it changes, geosteve

RabbleRouser: back to tiling terrains: how you change the elevation effects of one of the fractal terrains and still make it tile?

MetaKlaus: Change it of all the tiles

RabbleRouser: just record your processes?

ccasady: Rabble: you can't.

Sky Pilot: Make sure terrain not selected, if not animating it.

AuntiAlias: in resposne to Rabble's situaiton: Now a "my terrain changes macro recorder" would be nice here....

RabbleRouser: so tiling only works with one of the fractal presets then, right?

MetaKlaus: yes

AuntiAlias: !

ccasady: yes

AuntiAlias: I've done a bit of changes to terrains, say, adding a bit of erosion and a bit of mounds....

ccasady: tiling workd with al terain types except "Bryce Calssic"

gdmsynth: ?

geosteve: All good suggestions, but I've tried those things, but maybe if I go back to even earlier version of the files. Is anyone here animating with Windows 98?

AuntiAlias: I wasn't looking at the several tile terrains from above, so any imperfections weren't really visible -- p.o.v. was looking at mountain ridges...

PJF88: Presumably you can alter the tiled terrains away from the edges, and they'll still fit.

Rosy: seamless tiles! awesome

RabbleRouser: right... but just no"global" changes unless you spend some time tweakin

Sky Pilot: ?

keef: !

JeffP: seams in the tiles are difficult to eliminate...

AuntiAlias: yes, RR.... we got a follow up from geosteve and questions from gdmsynth and sky pilot, and keeg

er keef

ccasady: Susan, whos next?

AuntiAlias: Let me see if I can address geosteve a bi tmore

KathG: Time for me to go......had a great time....... Thank you everyone, learned alot :)

AuntiAlias: I presume that what you want to do is get your terrian back to a certain (unchanging) state, yes?

ccasady: you're welcome!

Rosy: bye Kath

AuntiAlias: If that's so.. then the idea is to remove the keyframes for the terrain as it moves.

geosteve: I'm animating the camera but not any terrains.

AuntiAlias: and still the terrains move?

geosteve: No, they change material properties.

AuntiAlias: it may be that you inadvertantly made a chagne to the terrain after you made a move with the camera

not terrain properties?

geosteve: No, in material. From granite to dark rocks with snow.

AuntiAlias: advice is same for either:go to Adv Motion lab and double-click the terrain or object till you find terrain.. and material (in sub hierarchy)

geosteve: OK

AuntiAlias: hold down the shift key on that material. You get a pop up menu

one option is to remove keyframes

Jsut for grins, beforehand, go to Mat Lab and click Copy material

so, in case you removed wrong material, you can put it back in.

back to our other terrain questions!

geosteve: Good thinking!

AuntiAlias: gdmsynth!

ask away!

gdmsynth: Is there any way to speed up (or automate) the "erode" tool in a 512/1024 terain? Sometimes I have to hold the erode button down for a long time in 512 terrains to get results. Do I have to hold it down for 30sec+?

ccasady: before too many people leave... I have an URL

http://www.tilenut.com/bryce/rocks/

PJF88: who's leaving?!

ccasady: Kathy left

PJF88: k

AuntiAlias: great rocks, Chris!! :D

gdmsynth: Silence...I guess I have to be patient and hold it eh?

AuntiAlias: yeah, think so, gdmsynth!

gdmsynth: K...thanks.

ccasady: I'm thinking...

RabbleRouser: how eroded are you trying to make them GD?

ccasady: Walter: you missed this: (these are new fractal types)

gdmsynth: I like 'em cooked a lot. I don't have patience though.

ccasady: http://www.tilenut.com/bryce/rocks/

dwalter: cheers

RabbleRouser: i never want more speed in the erode, but i guess youd just have to hold and wait

mmurphy: "hold" or "drag"?

AuntiAlias: are we done with gdm's question?

gdmsynth: Chris rocks!

AuntiAlias: no, I guess not! ; )

ccasady: gdmsynth, I think you just have to wait

Calyxa: dragging doesn't take effect until the erode has been calculated for the whole terrain, and at higher resolutions that does take a while.

PJF88: Walter = Daryl

gdmsynth: yeah. unless there are any ideas. Thanks.

ccasady: One other idea is:

mmurphy: ahhhh

boru: Gdm, I think it goes faster if you click repeatedly, rather than click & hold

or it's my imagination

Ideaman: Am I late?

RabbleRouser: (nice heiroglyphs in the rocks, tile!)

gdmsynth: But tell me, it is working in the 1024 mode right?

ccasady: errode at 128, then uprez to 256, errode, up to 512, errode more, then up to 1024 errode lkike crazy

MetaKlaus: gdmsynth: yes
