 Post subject: Pressure Sensitivity
PostPosted: Tue Dec 13, 2005 10:37 am 
I would like to request support for pressure sensitivity using drawing tablets.
Preferably Wacom models because they hold the market.
With pressure sensitivity, one could go from small details to large features within a matter of a split second.

In the attachment, the line on the left was done with a mouse while the line on the right was done with a digital pen.

This sounds like a very good idea :)

Just surfed the wacom webpage. Which product do you use? The Graphire4 would be the one I could use to start with. But there are better (and more expensive) ones. Do you know if they are compatible? Or do you have any experience programming them?

You are not incidentally living near Braunschweig and could borrow me one device for a couple of days? :)

I have the Intuos3 6x8, I probably should have bought the 4x5 since where you draw on the tablet is relative to where you're cursor is on the screen.
An area of 6x8 doesn't seem like a lot.
But once you start dragging your hand all over it, you're gonna wish you had a 4x5!
Some would say 1024 pressure lvls is a little too much and is only good for extremely fine art.
I think the Graphire4 4x5(512 pressure lvls) would work just as well as the others(if not the same) for terrain creation.
I don't have a thick knowledge in programming so I'm of no use in that matter.
Well, except for hinting you over to the developer section on the wacom site: http://www.wacomeng.com/devsupport/index.html

Sorry, I live no where near you and if this thing hadn't robbed me of $400 dollars I would probably lend it to you.
On that note, if you need a QA to test out your future releases....let me know! lol


To give you a better idea about the significance of this.
Here is a model I sculpted in under 10mins within zbrush.
It normally would have taken me 4 or 5 times loner!
Seriously.

Also, it takes about a week to get used to.
So I suggest spending some time in photoshop first playing around like a 4 year old with some brand new crayons! :D

This is really an interesting approach for terrain creation. When I find the time, I'll start experimenting with it. Thank you.

You don't have to reply to this.
I just wanted to point out this section of the site just so you can keep it as a reference:
http://www.wacom.com/productinfo/differences.cfm

I'm sure in the developer section they point all of this out?

I'll try to support it with one of the next releases.

I think this is something that more traditional artists will find appealing overall.

I very much look forward to this feature. :wink:

If you want to put your new device to the test in a 3D app. that's built to support pen tablets.
Then I suggest picking up the zbrush demo.
I use zbrush for a number of things but one of the fun things I like to do with it is modeling terrain textures.
Yes, I did say modeling textures!
I find by modeling my textures I can reach a lvl of detail that is beyond what you can do with a chopped up photo and not to mention there is no restrictions on what you can do with it.
Such as capturing it's true depth info by converting it into a normal map...et cetera.

I like the idea of using pen tablet for modelling in TC and I think it has a great potential. But I can not overview its whole potential at the moment, as I'm not very familiar with 3D modelling in other programs than TC :oops:. So I haven't completely undestood what you tried to explain to me.

Would it be possible for you to make a short screen capture video or a brief written tutorial with some screenshots to explain this to me? That image looks really cool.

BTW: to put modern user interaction to the top. I will additionally implement 3D navigation and placing of objects using a (6D) spacemouse for release 1.1.10.

I'll just point some resources out to you:

Register here:
http://www.zbrushcentral.com/zbc/index.php

ZBrush 2 Practical Guide:
http://206.145.80.239/zbc/showthread.php?t=3471

Download Zmapper and the Guide:
http://www.zbrushcentral.com/zbc/showth ... ht=zmapper

http://pixologic.com/zbrush/class/zmapper2.html (check out pg 72(aka pg 64 and then head on down to pg 77(aka pg 69) for the tutorial lol.

Download the Seamless Texture02.txt plugin or get my vr in the attachment:

http://www.zbrushcentral.com/zbc/showth ... ss+texture

Open up zbrush.
Click on help>List all Zscript Tutorials>Alphas: Alphacentury

I'll look into making my own Modeling Textures tutorials to make things a bit easier for everyone here...

Have you thought about implementing a shader engine?
It would be fun to play around with different shaders within pnp. Such as subsurface scattering(good for plant life), bump and normal mapping, detail maps, glow, refraction, reflection, et cetera.

If you're interested in this, then you really gotta check out Rendermonkey(ATI cards) or FX Composer(Nivida cards).
