Talk:Blender 3D: Noob to Pro/2D Image (logo) to a 3D Model

method 1 - bringing the outer circle into 3d
[Noob Note: I'm new to Blender but have been dealing with bezier's for a long time, and this method of creating the slashed circle seems excessively complicated (whereas the other alternative presented bypasses the point of using curves altogether). The inside of the circle is just 2 half circles cut out from the original larger circle and would only need 2 points to draw out (for each half). Here's what I did.

Another noob note: I found that instead of doing all of this, just insert the inner circle, rotate by 45 degrees, and scale and grab along y and x axis and you will have a much better looking circle

note added 12/08..... all these methods produce something that is "LIKE" the logo jpg but all end up different. Look at the picture..THE TOP PART OF THE LIGHTNING BOLD IS ON TOP OF THE RED CIRCLE... only the body and bottom tip of the lightning bolt are underneath it. The lightning bolt must be rotated on the x axis to correctly finish the logo.

method 3 - bringing the outer circle into 3d
(Another way to do it is to create a ring with 2 Tubes (SPACE -> Add -> Mesh -> tube). Scale one to the size of the outer border of the ring and one to the size of the inner one. Then in edit mode select 2 Vertices next to each other on the inner and outer tube and made a face (FKEY) which covered one segment of the ring. Then you have to spin it like described above (the number depends on the number of vertices you choose for your tube tube = 32 Verticles -> 632 rotationsteps). Same on the other side. If your faces are not in the right place go to object mode select the tubes an press SHIFT+SKEY and choose 'Cursor -> Selection' to center the 3D cursor.)

an other way (faster)
n00b note. This is an other way (faster) add a open circle, make it right size, extrude + esc, scale, mark them both and press F for fill, and rotate it so 4 vertexes are the corners of the line over the lightning, make edges with 2 vertex and F, I think u know the rest so ur done now :D

Rewrite
This tutorial seems disjointed, and several of the images have been lost.

Would anyone mine if I wrote another one from scratch on the same subject?

I am following this tutorial on another similar logo. Now that I have completed it, when I select one of the letters, ALL of the letters select (in object mode). I can't split them up and for example rotate one of the letters at a time. Sure I can select them individually in edit mode, but then I cannot translate in the z direction and do other things I want to do.

But in this tutorial the lightning bolt and the circle X are acting as two distinct objects. Is this something I missed in an earlier tutorial. Perhaps someone could add more detail about this?

OOPS!

Didnt realize you're going into beziers here. I'll find a more appropriate spot for this tute. Beziers, of course! I suppose I'll separate mesh modeling from bezier modeling from metaballs from etc.... I'll figure out a good spot for this, continue your good work on this please! --Spiderworm 13:34, 11 Mar 2005 (UTC)

Ok, looks like this tutorial needs some one to finish it. I'll give it a try. --Mrfelis 6 July 2005 02:55 (UTC)

This tutorial needs to be marked as incomplete and moved to the "Miscellaneous Tutorials" at the bottom of the main page of the Wikibook. I'd do it myself, but I'm completely wiki illiterate. This is my first post on a wiki. Jdwolfears (talk) 07:53, 20 May 2010 (UTC)


 * I think it's a good lesson, and will rework it and it's second page into something that useable. Pearts (talk) 13:44, 3 September 2010 (UTC)

Set up
This bit;

"Now scroll the view using by clicking and dragging the MMB and notice how the cube and image move together?"

Apart from the typo I'm not sure what its intention is because when you rotate the world by clicking and dragging the MMB the background image vanishes, as it is apparently only visible from the three orthogonal views & the camera; therefore by saying "...notice how the cube and image move together?" seems odd. I'm using Blender v2.40, so maybe this behaviour is different from v2.37.

Also, on the previous bit where we are playing around with the 'blend' function it could do with being mentioned how to input the exact 0.500 value again as it's nearly impossible to do it with the slider; i.e. click on the current value and enter it with the keyboard & then press enter. Just to help.

Also, in Blender v2.40 "Ext1: 0.2 Ext2: 0.02 BevResol: 4" appear as:

< Extrude: n.nnn >

< Bevel Depth: n.nnn >

< BevResol: n >

In more-or-less the same place; Mode: Edit or Object > Panel: Editing > MiniMenu: Curve and Surface.

[user:mr_spoon, 4/Jan/06].

OK It is probably just me but there appears to be a bit between "Polishing the Tracing" and "Adding the third dimension". The reason I say this is I have the latest version of blender and following the instructions as listed means that instead of a solid swoosh-type shape you get a solid shape with the middle taken out.

That image showing how to set up the curve it probably the worst for someone (like me!) who is trying to learn a whole bunch of stuff that is new...

The picture needs to be changed!!!

[From marinalan, Mar 16 2009] I am very much frustrated that I can not see in this tutorial original image that is served as background image for tracing, exactly "no symbol with lightening bolt" in png or jpg format.

Without this I can not follow and do steps.

Noob answer: I just used my own Logo and followed the steps, it still worked.

I had much more success with another tutorial, http://www.blendernation.com/tutorials/blender-3d-beginner-tutorial-creating-a-logo/

The missing images. How I failed to repair this tutorial in a brief try
I am going to ask to have them undeleted and give them a proper attribution. Pearts (talk) 11:57, 3 September 2010 (UTC)

Hi anybody (or everybody),

Just discovered this tutorial and wanted to use it to help myself. Then discovered that it's in state of disarray.

I tried to find out what's wrong with the missing images, so I checked the Commons deletion log for one of them ... but either the search is faulty, or I don't know what, because it's yielding no results:

http://commons.wikimedia.org/w/index.php?title=Special:Log&type=&user=&page=File:Blender-2dlogo-polish-final.png&year=&month=-1&tagfilter=

Should I believe that this file had never been uploaded in the first place? Maybe I'm distrustful, but somehow I doubt this...

Then I checked the history of this tutorial, to look for some useful c[l]ues as to what might have happened.

One notheworthy edit is this one (diff) by User:Mike.lifeguard on 20 October 2007. His description of the action is:

Removing instance of image Blander-sample-2d-logo.jpg that has been deleted because "nld>7d"); using TW)

Now no sane person is going to know what sort of excuse "nld>7d" is. But we have Google, so I located the description of this mysterious symbol... on said user's own subpage (User:Mike.lifeguard/Deletion_reasons), and only there (hey, that's a notable symbol then, isn't it). So I was lucky that Google placed this result on the top position globally, otherwise I would never find it. (So it must be somehow notable in the end.) The explanation is perhaps even more mysterious than what it explains:

 nld>7d
 * nld>7d

Well, lucky me that I can comprehend wikicode—not everybody can. So I typed in WB:NLD manually in the search box, only to get redirected to... Media.

This policy explains our requirements for images and other media files used on Wikibooks.

Great! So what do we know? All that we learn is that the picture has been deleted because of failing unspecified "requirements"!

So we end up knowing nothing, unable to make our own judgement of that long-gone operation. But at least we have a proof (!) that the file  existed, and had been deleted, rather than never uploaded in the first place!

So I re-test the Commons deletion log search for this one file... again, to no avail. Now we know that it is not just this particular tutorial: it is basic mechanisms of Mediawiki that appear to be falling apart. (Or, if I am simply unskilled enough to use them properly, how many other people are? If not for problems of the kind that I discovered, I'm sure someone would have repaired this tutorial by now after all these years!)

Summary
Summing up, the problems which I have encountered in the way of my effort to repair this tutorial appear to lie in the ways Wikimedia mechanisms are at the moment functioning:


 * 1) The deletion log on Commons is a bit hard to locate. Entering "deletion log" in the search box yields no results. I have found it by using a separate search on the Commons "Help" page which works for help pages only. I don't know why the primary search box should not have universal scope of operation like it has on Wikipedia. (Okay, it does—as I discovered later—but the user must know upfront which namespace to select... only to get an old, defunct deletion log page from year 2004. For readers' information, here is the Commons:Special:Log/delete—don't confuse with a Wikibooks deletion log.)
 * 2) The deletion log search almost never appears to work. (Well, quite wickedly, it seems to work only for the kind of files, disappearance of which couldn't go unnoticed by a large audience...) To compound, rather than ease, this problem—the search doesn't seem to allow for filename filtering, so you can't find a file without knowing its full name. (Why this restriction, so unnatural for computer systems—do we have something to hide?) Example:http://commons.wikimedia.org/w/index.php?title=Special:Log&type=delete&user=&page=Image:Blander-sample-2d-logo.jpg&year=&month=-1&tagfilter=
 * 3) Accountability for actions of possibly long-departed users: someone has deleted a (perhaps!) good stuff someday many years ago under a pretension of informed decision, such as "nld>7d" or even "dafq3dsjh", leaving an otherwise 90% good tutorial in a state of disarray and seemingly making extra effort to make it irreversible. What next? What is our direction starting from this point?
 * 4) Some established habits of higher-profile users: It's easy to delete files without considering the fate of some greater work they were part of (such as this tutorial), and not even bother to leave notice about what happened and why on the pages that have linked to them. It takes comparatively little energy to delete a file. Unlike to create one. Even though both operations have equally profound effect. Some people seem to have lost this sense of balance (or have never had it in the first place) between these two opposite modes. Perhaps it's their broader pattern that they do things merely because they can do them.
 * 5) Commons pages of deleted files look like these files have never existed, rather than been deleted—making it much less likely for someone to give it a second thought and possibly spot an abuse of deletion.

The bottom line: I failed to find out what happened (and why) to the images missing from this tutorial, and to repair them, due to multiple obstacles in the ways Wikimedia sites work at this time. I'm hoping the problem only looks this big while actually not being so—that I just had bad luck today or so. But facts are there.

P.S.
Hey, I found them in the deletion log!


 * 1) http://en.wikibooks.org/w/index.php?title=Special:Log&type=&user=&page=Image:Blander-sample-2d-logo.jpg&year=&month=-1&hide_review_log=1
 * 2) http://en.wikibooks.org/w/index.php?title=Special:Log&type=&user=&page=File:Blender-2dlogo-polish-final.png&year=&month=-1&hide_review_log=1

I was looking in the wrong Wikimedia: Commons—instead of Books. (It's because the missing image links redirect to Commons.) The proper deletion log page is simply Special:Log.

So one legible explanation why they were deleted, that I found, is this:

 image with no copyright info, listed for over 7 days, no links.

It appears that the author of this tutorial has disappeared from Mediawiki with the last contribution ever on 19 September 2005. Which is shame. I'm hoping he is alright.

Unfortunately, after finishing his work, he failed to tag his (probably genuine) illustrations with copy-free licence.

Even more unfortunately, this omission was only spotted with a two-years delay. (Sometimes it's better quick—or never.) By that time, he was not with us anymore to avert this little but critical error.

And that's how a good work has gone shit, instead of being preserved for years to come.

Theoretically, I guess, it is possible to undelete them for the purpose of individual re-creation and tagging with a proper licence—if someone was so determined.

—6birc (talk) 02:20, 5 May 2010 (UTC)

It appears that the author is alive—it's just an extreme case of loss of interest in Wikimedia (perhaps computers in general): here is his Wikipedia edit two years later, in 2007. All we learn about him from there is that he had his 9th grade biology class in year 1984. He has turned with his interest to cats since. Now I can go to sleep ;-). —6birc (talk) 02:47, 5 May 2010 (UTC)


 * people come, write about what interests them, then lose interest, and dissapear... it's the way of the wiki... thanks for researching these! Pearts (talk) 13:42, 3 September 2010 (UTC)
