BryceTalk Tuesday Current Project Discussion,
June 8, 1999 — Part 2

AuntiAlias: important point: Make sure that you set the terrain resolution to higher number (like 512 or 1024) before you paste in Terrain editor!

Darreng: Always

AuntiAlias: if your source image is, say, 1024 x 1024, and your terrain resolution is 128....

when you paste, your 1024 terrain canvas will be reduced to 128....

Arby: that great to hear, could be the focus for a Euro-meet

Anon: But it is the amount of grays you can get Aunti

AuntiAlias: yes, true....

oen thing that Ales mentioned at Bryce camp is that internally, Terrain Editor works in 65,000 levels of gray...

so...

jeon: sorry..MetaJohn.. do you know this image.. http://www.ip.co.kr/metoo.jpg

AuntiAlias: if you can do something to your terrain in the terrain editor, after pasting, such as a blur or soemthing

Darreng: I've said it before... and I'll keep saying it... Full Screen TE!!!

please

AuntiAlias: you'll get additional level of smoothness put in....

george: heh

Darreng: :-)

Arby: yes I usually do 1024 for foreground objects, what is the restriction preventing a 2048 option in Bryce?

george: Do you know how many times one can smooth before the geometry of the terrain changes?

AuntiAlias: yes, the limitations of the size o fthe terrain canvas are known! : )

Darreng: once

:-)

AuntiAlias: Anyone else got a project going currently in Bryce that you want to tell us about?

george: i.e. how many clicks work as a smoothing feature until bryce begins to alter the geometry of the lattice itself in a visible since

MetaJohn: Yes jeon

AuntiAlias: Stuff you're doing, stuff you're encountering?

Schbeurd: In Bryce 3.1, I created a scene with three volumetric lights. The rays of light crossed each other, but the result was awful

AuntiAlias: george, I think the answer to that is once...

george: neato

jeon: tell me.. who there? metacration people?

AuntiAlias: another thing that I've done some experimenting with, but not for finding new levels of smoothness, is to change resolution from, say, 512 to 1024....

let the internal part of the resolution add smoothness

but that may not always work

Schbeurd, was there horrible icky banding in the lights?

Beartrap: AA - are you saying work at 512 and when you're done up the resolution to 1024?

Darreng: You need to turn up the quality in the ME for volume lights Schbeurd... to avoid a criss-crossing effect...

More tortioise!!!

Tortoise

george: Aha...I have a simple question....not really tech heavy or anything...do I put a ? after my name to indicate that?

MetaJohn: jeon go to the room called discussion room

AuntiAlias: Beartrap, I'm saying that if I'm trying to tweak a terrain in some minimalist way in order for Bryce to take an image that started at 256 levels of gray and turn it into 65,000 levels of gray, that's one way to minimally alter the "image" in the terrian ca

canvas

but!

it's an idea.. not really tested, may work well in some cases, but be horrible in others

Arby: Anyone into fractals will have heard of Fractint?, this program can output a POT file format which is 16bit (I believe) heightlevel which can be imported into the Povray raytracer. Maybe a plugin for B4 could handle this format?

AuntiAlias: interesting idea....

oh!

Beartrap: anything that can smooth a bit more... :)

Schbeurd: I'll try that Darreng, Thanks

AuntiAlias: TIP.. mega tip! cool tip that got me way excited when I discovered it at BryceCamp!

since we're on the topic of Terrain Editor

and discussing how to get the most information in there as possible

Darreng: Render times will suffer though... obviously Schbeurd

george: Arby...if you can open it in an app that reads 16bit...you shoudl be able to past it into the TE directly

AuntiAlias: do you know how to get to the Deep Texture Editor from Terrain editor?

Darreng: no we don't

:-)

AuntiAlias: press down command-option (mac) or ctrl-alt (win) and click the Picutres button

Arby: george, I think thats the problem, AFAIK only povray can handle it.

Darreng: ahhh

nice one

AuntiAlias: and... DTE!

THEN!

Darreng: I love shortkeys

yes?

AuntiAlias: set your output from DTE to be alfa only

george: afaik???

AuntiAlias: that makes just grayscale

Darreng: right...

for?

AuntiAlias: and then what you see in the terrain editor is what you get

Darreng: ahhh

AuntiAlias: Some voronoi noises are great for making boulderish walls

but here's the kicker

what you see in the combo window is what will be made into your terrain

Beartrap: I'm too polite to shout so please assume caps lock on... amazing!

Darreng: I better save this Chat...

george: command option and the pictures button? doesnt seem to work....

Arby: any general tips on the new noises? they seem very similar to me.

AuntiAlias: I use 2D preview

hang on a sec.. still getting to the really good part : )

so

assume for a moment that you want to make a boulderish wall

out of your terrain

Darreng: To my shame I have only used B4 about twice and once was yesterday!!!

Too busy in Bryce Talk

KathG: Thanks Aunti like that one :)

Darreng: sorry AA... carry on

AuntiAlias: which means that when you work with that terrain, you'll prolly be stretching it on the X axis

MetaJohn: Shame on you Darren <grin>

AuntiAlias: good for flattish boulders

but!

Sumo: I hope these tips are going into your new book Aunty?

Beartrap: will the logs of Tuesdays' chats be available on the MC site?

AuntiAlias: i.e., the boulder shape flattens the wider that the terrain gets when you resize its wireframe

so!

(this is the good part)

Darreng: good question Steve

AuntiAlias: if you want a consistent boulderish shape

when your terrain is wider

then

Beartrap: (company about to arrive and I don't want to miss anything!)

MetaJohn: I will send you the log bear

AuntiAlias: go into the Noise editor and change the frequency of the noise so that it's squashed on one axis

the one that appears to be the horizontal axis

Beartrap: thanks John!

AuntiAlias: then when you resize the terrain, VOILA! the regular boulderish shape gets put back in!

in other words, you add more detail on the X axis... which you'll be taking out again when you stretch the terrain's wireframe

Darreng: er... I'd have to play with that before I get it

sorry... long day!!

AuntiAlias: yeah, I figured that might be the case

hm!

I think I'll cover that in thursday night's DTE discussion

Darreng: yayyyy

AuntiAlias: that's a nice little do three tricks and then you're there! idea

george: (whispers) when you open the TE, you click on the pictures tab with option and command depressed?

AuntiAlias: and as to logs

KathG: That sounds great..will play with that later Thankyou :)

AuntiAlias: yes, these will be posted. Sorry, I'm behind on log stuff, but should be all caught up by friday

Darreng: excellent

Beartrap: :)

KathG: Great


 

 

AuntiAlias: um...

speaking of logs...

I got a question for you

Darreng: who?

AuntiAlias: do you find the logs of the events valuabel?

george: Yes!

Darreng: Oh yes, yes, yes

AuntiAlias: you is everyone in this room but me or metajohn

er valuable

Darreng: yes YES YESSS YESSSS

Sumo: Yes, there is always something of interest among the chat.

Darreng: !!

AuntiAlias: george, darreng say yes, sumo says yes...

Beartrap: absobloodylutely!

AuntiAlias: others?

Arby: they would be better without 'x is off to render mirrored....etc.' sprinkled throughout <ed note. Point taken. Notice that comments are now gone. Like it?>

Darreng: true

KathG: Yes I save them under MHT Ext and themn I can refer to them when I what :)

george: (help....question...)

Darreng: not splines george...

Anon: Sorry AA. I never read one yet!

Darreng: ??

:-)

Schbeurd: Logs are very interesting AA

george: (nope not splines)

Darreng: cool

AuntiAlias: Anon, 'sokay.. that's meaningful feedback too!

no need to apologize

Sumo: Aunty asked about current projects, I am currently trying to reproduce historical battlefield terrains in Bryce 4.

MetaJohn: Would it be useful to record the Moday discussion logs also

Sumo: Is that obscure enough? ;-)>

AuntiAlias: because, from my end, I post the log and then think nothing of it again. Just want to know if it's a valuable thing to do

Anon: You using DEMS Sumo?

Darreng: have to go... this machine is being used for 'tuorial night'

Bye

AuntiAlias: fascinating, Sumo! tell us how you are doing it

Sumo: No DEMS - I have to make them up in greyscale from historical maps.

MetaJohn: Why not use Dems?

Sumo: The problem I am having is getting the right 'scale'

AuntiAlias: tell us a little about the technique you are using for that, Sumo! : )

Beartrap: company's here... have fun, all!

AuntiAlias: teh right vertical scale?

Sumo: Yes, vertical

KathG: By Beartrap have a good time

george: Sumo....if you are having troubles, I reccomend using Illustrator 8....

AuntiAlias: in terms of grayscale values you use?

Sumo: I have just got hold of that, I have been using Corel for the last six years (don't laugh)

AuntiAlias: so you scan the maps?

MetaJohn: hehe

george: You can create a gradient mesh based upon [erhaps a scan of a map of a battlefield....

then make a gradient mesh over that scan

AuntiAlias: I guess I don't know what the scanned historical battle map would look like

george: You could make the mesh with specific colors in specific spots

Sumo: It seems to be a problem of the relative greyscales - ie what should be a sunken road lokks like a gorge...

AuntiAlias: er does look like

Schbeurd: Yes, AA. Poor french speaking guys like me sometimes get in trouble when the discussion goes to fast (like this eveningt. I can read the logs just after they're published on the web. Continue to post them.

Sumo: A map is usually a series of elevation lines

AuntiAlias: yes, the subtleties of grayscale to represent 2D information to us (i.e., here's enough contrast to distinguish a road from not-road) is altogether different when you're dealing with G2H info

Sumo: DEMs are little use because terrain has often changed

george: Illustrator 8's meshes would be invaluable imho....

MetaJohn: You should be converting the elevation contours to graysacle values in Illustrator

Sumo: I will certainly think about meshes - they are a very powerful feature and I have already used them to create general terrains with far more control

MetaJohn: This should work just fine

george: you can create very precise outlines.....I you add points outside the road and then inside....the ones outside the road prevent the color from seeping around

thats a much better idea john :

Sumo: How to convert John?

AuntiAlias: these illustrator techniques sound fascinating!!

Sumo: At present I am hand tracing

MetaJohn: You will have to trace the contours in Illustrator and them use them as edges of a blend

george: I've done some illustrator/bryce combos....it works farily well and you can create very precise shapes etc

Sumo: okay, that makes sense

MetaJohn: Not quick

AuntiAlias: you are tracing and creating vector information (i.e, illustrator, corel draw) or bitmap (painting photoshop painter etc.) information

Sumo: Nothing is quick!

george: vector

in my case

Sumo: vector in mine, then exporting as a greyscale bitmap

MetaJohn: I suggest vectors are better at this, more manipulatable

AuntiAlias: right...

george: made a rough model of a train using that technique....took a 2d pict of the train....then used that for scale in illustrator

Anon: Can n ot do that in Corel, it would take forever

AuntiAlias: Sumo.... have you gotten a result yet (from a map) that you like? or still working on perfecting the technique (I suspect the latter)

george: the vectors allow one to continue to manipulate the shape and try other options

Sumo: The general point is I have found Illustrator easier to control for terrains as I have more control over vectors than the TE - but then I am one of these people to whom Bryce has conferred 'artistic' skills

MetaJohn: Yes George, and to change the gradient if the turn roads into gorges

george: Exactly

Sumo: Very much working on techniques. I am doing Gettysberg among others and it is unrecognisable!

MetaJohn: Vectors in the TE is high on our wish list!

george: Heh

Sumo: And Mine!

george: i'm working on it : )

MetaJohn: Has the terrain changed at Gettysberg?

Sumo: Not greatly, but it is weel docuimeted

Sorry...

Sumo: Well documented compared to the European terrains I need to work on.

Schbeurd: God damn computer...

Auntie, one more reason for you to post the logs : when you lose your Internet connection, you can see what you've been missing...

AuntiAlias: can you start with a DEM of modern gettysberg terrain and then change that?

Anon: Sorry, ISP problems

Sumo: Yes, I could - but haven't got one!

AuntiAlias: yes, true re: connection problems!

DreamVoyager: SUMO... if you are scaning in the maps and then working in vector, try Adobe Streamline for a quick translation between the scan and vector... then you can edit it in Illustrator. Pehaps not the best sollution, but it might be something to test.

Anon: They can be found for free at the USGS site

Sumo: Okay, didn't know that!

MetaJohn: Illustrator also "streamlines" quite well

george: (question still re that tip about the DTE in the TE)

Sumo: Streamline? The tracing tool? I have an old version that needs upgrading.

AuntiAlias: you'll have to work to somehow scale your scanned information with the DEM information....

DreamVoyager: Aha... didnt know that. I never use Illustrator.

MetaJohn: True Anon, but I would not know where exactly to look

AuntiAlias: but then that's a new technique to perfect! : )

Sumo: Thanks for that input. Worth the upgrade price alone!

Anon: Me either

Sumo: Anyone here going to the Bryce UK meet up on Sunday?

AuntiAlias: Tell us more about the meet, Sumo!

Anon: Being a Brit I don't know anything about no Gettysberg!

DreamVoyager: Living in Sweden... didnt know there was a Bryce meet in UK.

had I known, I might have got a ticket... need to go to UK anyhow.

Sumo: First meeting. In London. About ten of us have decided to meet, eat pizza and see The Matrix that opens this weekend

MetaJohn: Very soon Dream, but I think it may be a small one

Sumo I am trying to get you guys a door prize for a raffle

AuntiAlias: whee!

Sumo: Great!

MetaJohn: Tin of Mother

DreamVoyager: Iv put initiated a meeting for Swedish Brycers. Meet, share tecniques... those that cant be there, will be there via the Palace chat.

Schbeurd: And what about a European Bryce camp or something similar ?

DreamVoyager: Yes. That would be nice, Schbeurd.

MetaJohn: Some one has to put it on, and we will give all the support we can

Sumo: I'd go (I nearly came to the US one!)

AuntiAlias: sounds wonderful! Sorry I can't make it (as if!) but I'm glad to know that there's a meeting on Sunday!

george: <?>

Schbeurd: What exactly happens in Bryce camps AA ?
