ios - Load .obj file out of Blender -

-

Now the Blender 3D .obj files are imported to do some work searching for the Iphone application.

I can get the details to apply in that way in any way!

I do not want to use any engine, I just want to know the steps that are completely and basic to me.

There is nothing in fact on www. You can get articles from 2005 - 2008, but these are not up to date and nothing works.

So, does anyone have to do this?

Take a look at the source, and look at the ozloder. He created ob to be able to load the obz file, and it should work in several platforms (including iOS). By reading the source you will see that it is really simple to make the object loader to the corner, but when you start taking care of normal and textured courses, it becomes more complicated. Here's a simple algorithm for scraping the OBJ file (I will stop parsing the corresponding tpl file for the reader's own research):

  1. Read in the file's format, starting all Throwing rows
  2. with # (comments) looks vertical: v 1.000 1.000 1.000 , therefore, if the line 'v' Spaces and stores (and convert to float) in the empty space 3 floats have an upper To divide.
  3. Normal look: vn 1.000 1.000 1.000 , therefore, if line starts with 'vn' is similar to number 2, but normal Store in the form.
  4. Texture Cores resembles a possible third vt 1.000 1.000 looks like [w] store values ​​and divide the line in the same way.
  5. Now it becomes difficult, there is a description of the face which is f1 / 1/1 2/2/23/3/3 by this index of every corner of the shape The most difficult part about this is that the OBJ file type uses three indexes instead of OpenGLAD or Direct 3D, for they are describing 3 corners / textcold / normals (in that order) for (usually those are triangles) . So you have to rotate around the order of your sequence / code / normal so that you can use indexed drawing on the sources. Eg

    e.g. Basically you have to be f 1/300/30 40/22/400 20/30/10 more f 1/1/1 2/2/2 40/40/40 < / Code> By changing the order

    gives you an idea of ​​this algorithm and shows an example about a high level algorithm (going down midnight on this page), and the source code is your For reference, check out can be found.

    Anyway, tell me that you need more help. :)

    Edit:

    The way you look at something like this: f1 // 4 2 // 5 3 // 7 Concerned No, this is a valid file that is intended and simply means (in this example) that there are no textures cores

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

ios - Replace text in UITextView run slowly -

-
I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
