Can we connect webgl and scratch? - webgl

Is there anyway we can combine scratch and webgl.
I tried to search online for anyway to do this, but could not find anyway.

Using Vulkan output in electron

I want to use Electron as a debug overlay for a Vulkan Render Engine im building. Since i have a lot of requirements on this debug tool writing one in engine myself would take way too long. I would like to use electron instead of Qt or similar since i feel its a lot more powerful and flexible with less effort (once its working).
The problem is now that i somehow either have to get my render output to electron or electrons output to my engine. As far as i can tell the easiest solution would be to copy the data back to cpu then transfer it. But that would be extremely slow and cost a lot of bandwidth. So i was wondering if there is a better solution.
I have two ideas to make it work but i didnt find any ways to implement them or even anyone talking about it.
The first would be to have electron configured to run on the gpu somehow get the handle for the output texture and importing it into my render engine using vulkan external memory. However as i have no experience with chromium and there doesnt seem to be anyone else that did it this i dont think it would work out to well.
The second idea was to do the opposite. Using a canvas element with webgl and again using vulkan external memory to copy the output of my engine to a texture and displaying it. I have full control over the draw process here so i think it would be a lot simpler and more stable. However again i found no way of setting up a webGL texture handle as an external memory object.
Is there any better way of doing this or some help on how to implement it?

Cemetery Mapping System using ArcGis

I'm currently working on my thesis, I need help on how to make a cemetery mapping system using arcgis, im not very familiar with gis but im willing to learn so i can pass. If you know any tutorials related to the topic or if you've done something like this in the past, feel free to help! thank you
Are you doing it from scratch? In ArcGIS you can upload shapefiles that you download from the internet. You can also create your own shapefiles.
I guess some tutorials like this might be helpful:

ArcGis is awesome, though a bit overwhelming at first. Have fun!

iOS - Object recognition in images

This is a known area and OpenCV might well be involved, but still to start from the scratch.
How has something like Evernote's scannable app been developed. I mean, how does it automatically recognize a document using a camera and then extract it.
What are the UIKit frameworks involved here and what are the libraries that may have been used. Or any nice articles or blogs. How does one go about understanding this.
This tutorial is what you might be needing. Although, this tutorial is in Python but all these function are available in iOS bindings.
Here, are results you will get.
Once, you have the ROI i.e. the page, you should run OCR to detect the characters. For this you can use Tesseract and this tutorial might be helpful.
For anyone coming here now, there are better solutions now. CIDetector does precisely this. And to have it working on a live camera feed, you'd have to use it on live CIImages being generated by AVFoundation (rendered using Metal or OpenGL).

Web application framework that suports 3D

I have an idea to develop a website that would help people to model 3D worlds, use 3D models and so on.
For example, based on my reseach, I could use Unity Framework to create this type of application for PC/MAC.
I am wondering if there are similar frameworks available for pure WEB?
This is my first time looking into this and I do not have any expertize in this topic. Please advise if you have any opinions or expertise in it.
Unity indeed has support for 3d on web, but it requires from user that it has installed Unity player. Users might not like that.
However, with webGL, you would have absolute control over the look and capabilities of your product, users wouldn't have to install anything new, it would all be pure web and only IE users would be damaged, because IE still doesn't have full support for webGL.
To develop with webGL you can do it from scratch, or you could use some of the existing libraries/3D engines that would speed up your work and give results much faster.
Here's a list of webGL engines: http://ffwd.typepad.com/blog/2011/04/webgl-what-flavor-is-your-engine.html, it seems that most used are Three.js, Scene.js and there is also Goo Engine (http://www.gooengine.com/).
Hope this helps.
Check out 3DTin, it does seem to deliver a part of what you want to build, using WebGL:

Augmented Reality Help

I need a help to develop a small application on Augmented Reality.I have spend almost a week trying but with no proper solution.Tried some sample code but still not successful.
I have seen many videos and want to develop something like that.
for example my code should detect only square or any particular shape.And then after detecting the square and another Image should appear on the screen.
Please help me out.
This stuff is hard, but most new cool things are until they are no longer cool or new.
You can play with AR Toolkit until you are familiar with the functionality and then attempt to dive into the setting and mess with those, then maybe look at the source.
