Google Maps-style quad-tree of materials on a single plane in Three.js – 1x1, 2x2, 4x4 and 8x8 -

-

I am trying to get a quad-triggering content (images) on a plane and I'm not working , The closer that a Google Maps-style zoomable tile gets, the closer it gets.

In short, I want to create a 1x1 image texture (covering an aircraft that is wide and length of 256 units) which can then be replaced with 2x2 texture, then with 4x4 texture Can be changed, and similarly.

Like the example image below ?? |

Texture Levels

Ideally, I I want to avoid making a separate plane for the level / number. A correct solution of the segment will allow me to break an aircraft into 8x8 segments (the highest zoom) and update the number of texture on the fly. So it will start with a 1x1 texture in all 64 (8x8) sections, then change the texture of 2x2 with each texture covering 4x4 fields, and so on.

Unfortunately, how can I not do this? I searched the materialInndex setting for each face, but you have not been able to update those people who will not work after rendering first. I have tried to look for UV coordination, but I do not understand how this will work in this situation, nor how it is actually implemented in three. Js one? For documentation / examples there is very little specific case.

A vertical shader is another option that came in research, but then I do not know enough to understand how to do this Confusion.

All help with it, it will be one such technique which is the other three. JS will prove valuable to the user.

100% make sure what you're trying to do, whether you're texture atlasing / Different textures based on zoom / different texture), but if you are looking for a trend-tree based texting that grows in detail you zoom in, then it is mandatory That's what the mimmapping is and what it does.

(The reason for this can also be used for all kinds of weird things, but this is another adventure)

Usually the Mimmap Ping is used by you Is based on filtering - though it seems that you need more control over it.

I have created an example which is three. JS is hidden in the source tree which can help:

which shows you how to automatically generate each mapmap level instead of manually loading it .

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...
