Tattoo 0.04 - Return of the Texture

| ||
| Hi All, I think I've cracked it. I managed to get hold of a Radeon 9700 from a friend's pc that I was repairing. :) Before I describe what it was here is the download to test. I tested it on both the Radeon and the Geforce FX9700 and it appears to work well on both. <paranoia mode> Could anyone who experienced the prior corruption confirm that the problem has in fact gone away </paranoia mode> Download 0.04 * The cause * 1) BglTexFromPixmap converts textures to RGBA format 2) I'm copying from the backbuffer to textures 3) *ATI CARDS APPEAR TO HAVE AN ALPHA CHANNEL IN THE BACKBUFFER!* Nvidia card appear to have no Alpha in the backbuffer, but ATI cards seem to. This means that the alpha component from the brush was getting written back into the source texture, then it became semi transparent and all hell broke loose as it was invert blending with the brush etc. This means that I needed to switch blending off and on depending on it being either a grab from the texture, or a render from the brush respectively. It was a very tricky thing to diagnose. Hopefully there isn't anything else I missed. :)  |
| ||
| Nope -- no alpha now, but still getting that weird pink/black texture with writing in it! |
| ||
| All is well on my end. |
| ||
| Sayyyyyywhat! Sorry, James, do you mean it has the same corruption as before? (would you mind kicking your GFX card for me ;) Are the Catalyst drivers up to date? @Noel - Good to know at least. |
| ||
| Works fine here now (I had corruption before). |
| ||
| Anyone with a Mattrox card? I remember that some Radeon driver versions and pretty much all Mattrox cards failed on the original Blitz3D Tattoo, I was wondering if the same was true now. So is it only James' Card that still sees corruption to the painting then? |
| ||
| It works here! Hooray! A small request: add tablet support, see my sig :) |
| ||
| A small request: add tablet support, see my sig :) Yup that's next up thanks. Problem is my GFX tablet is broken. So I'll have to let you test it for me :) |
| ||
| ok. TattooMax 0.05 to Test. It should have GFX tablet support now so that the pressure will control the alpha component of the brush. If you're using the mouse it is controlled by the Mouse wheel. As I mentioned my GFX Tablet bit the dust some months ago, so I have no way of testing it. Other Controls: MB2 = Rotate Model Via Mouse A / Z = Zoom in / Out W = Wire Frame Arrow Keys = Rotate Model. PG_UP / PG_Down = change Brush Size Space Toggle = Texture Filtering Off/On for Model. Now I'm missing a GUI... :/ |
| ||
| Everything works fine on my side now :P this igetting to look nice |
| ||
| Terrific :) Had the ATI problems with version .03, works like a dream now. ps, Not sure if it was on the Newtek forums or another Lightwave user group but someone mentioned taking another look at the older version of Tatoo as FI's chalk couldn't handle subpatches. Anyway, here's the question, will the new version of Tatoo support the new subpatch modes within LW 8 and beyond? |
| ||
| Hi all, Not sure what the final specs will be. It has a lot of potential, I agree, but I'm unsure whether to wait for Max3D or continue to hammer my own 3D implementation out as I go. A lot will hinge on how well the GUI module turns out I suppose. Can anyone confirm that the GFX tablet pressure sensitivity is working? |
| ||
| Yep, pressure sensitivity works. It does seem a bit over-sensitive, but I think that is due to the way you draw. Ie.: That you keep drawing on the same pixels in an accumulated way. |
| ||
| It shouldn't keep painting if you keep the pen still. It detects if you move and paints as you go (a bit like a ball point pen). ALthough I do need to set up a step parameter. It's probably quite difficult to put a low enough pressure on the tip as the alpha needs to be about 5-10% to get just a tint. Glad it's working ok though. I miss my GFX tablet. Would this work with any tablet? Or only Wacom and similar? |
| ||
| It's working on all tablets it's been tested with. Ie: Wacom: Intuos2, Intuos3, Graphire, Cintiq If you're looking for a cheap replacement the Trust work tablet 400 is ok, although the pen is a bit clunky (because it has a battery inside). The Medion models I've tried has a tendency for cursor jitter, so they're not much fun. Trust: Work Tablet 400 Medion: Unknown (rebadged Mustek according to Scouse) |
| ||
| Sad thing is, the tablet itself seems to be detected and the driver says its there, but it no longer recognised the pen. It's an old Intuos one. I think a replacement pen is about £50 or so, but I would hate to buy another Intuos pen only to find that the problem was with the tablet itself. |
| ||
| perhaps you can borrow one, to test...? |
| ||
| Yeah, give Wacom a call and ask if they can sponsor you a tablet. They're pretty friendly so I think they would be interested. |

| ||
| Working correctly on my Radeon X600 Pro now. Thumbs up. |
| ||
| Works prefectly here on both my crappy Radeon 9250 and Geforce 6600GT :D |
| ||
| only to know... Is possible to make a software for modeling a 3D figure instead of paint it? |
| ||
| It's easy to make something to make models. The trick is to make it easy to use yet powerful. It's a balance that is hard to get right and few packages really get it right IMHO. |
| ||
| BlackSp1der: Yes, although you would preferably need a nice GUI (hint hint BRL) :) |
| ||
| Just letting you guys know that ASDA in the UK do a tablet for £23.00, I have one and it seems fine with all products I've tested it with (although not Tattoo yet). Great as a cheap option. I guess only the bigger stores with PC equipment sections will stock it. IPete2. |
| ||
| Worked fine with my Wacom graphire... |
| ||
| Worked fine with my Wacom graphire... Good. Still waiting on the GUI. I am also not sure if I should wait for Max3D... |

| Just letting you guys know that ASDA in the UK do a tablet for £23.00, I have one and it seems fine with all products I've tested it with (although not Tattoo yet). cool yes ive been out and got one from asda :) so checked here and works fine on my trust gfx tablet. |
| ||

| ||
| I bought your old Tattoo app, and MAN this version is SO much faster! whats the big secret? :) |
| ||
| It's purely a Driver thing as far as I can tell. The old one was done in Blitz3D and actually does a lot more than this Alpha one in the background. On some Nvidia driver versions the speed is the same between the two, on others, the OpenGL one flies far ahead. Once the GUI is out, I'll try and put together a bit more of a working test. |
| ||
| Getting anything out of the GUI now then, TeraBit? Please tell us of your progress :) |
| ||
| Yes. I've got this running in a GUI window that resizes etc. Got to start plumbing in all the boring bits now... Once I've got something interesting to show I'll post an update. |
