I am new to WebAR, but I have experience with building AR scenes with Unity3D and software such as Vuforia and 8thWall.
I have a question with the markers with AR.js. Why are they stuck with the thick black border? Is the software not able to just recognize a unique image like how Vuforia and Wikitude works? I apologize for how naive I may be when it comes to WebAR, however, I see this as an issue for the adoption rate of this technology if developers cannot use truly custom images and patterns. Is there a solution available that I may have missed somewhere? What happens if someone deletes/erases the big black border on the marker? Does it still work?
Thanks to anyone who can shed some light on this!
Ar.js uses artoolkit and therefore is marker based. If you want to use it, there is not much you can do about it. Still You can have unique images inside the black box but not much else.
Worth mentioning, it is possible to make the borders thinner, there's even a branch - work in progress worth looking into.
Aframe-argon tried integrating aframe and vuforia, but i'm not sure if it's up to date.
I want user to pick an image from gallery then user cab give multiple effects to the image like grey color,vintage,sepia,retro etc.I have searched a lot for the solution.Please guide how can i achieve this task?
Thanks in advance.
if you just simply wants apply the effects which you described you can use these
or you want to apply many different filters and also make new filters to apply on that images use GPUImage Framework
its very fast and easy..
Please try with this demo.

This is the better then anything.

Use Core Image Framework by Apple. Cheers! This will help you
I've recently upgraded to the latest version of Highcharts v3.0.2 and now one of my existing charts is rendering in a strange manner. See 'Sector Chart' at this link
http://bit.ly/10hU8TW
The circles seem narrow and out of alignment. Can anybody point me in the right direction to solve this?
Many thanks
Please take look at v3 configuration of http://www.highcharts.com/demo/pie-donut
I have two sets of array containing 7 objects, with values in one and dates on another.
I would like to generate a simple bar graph with date on x axis and values on y axis.
I searched google and ofcourse stackoverflow, but I didn't find a satisfactory answer.
In every answer, it's all about Coreplot, which I don't want to use because of it's complexity(Me being a begineer in ios development).
Is there any other way except, CorePlot to achieve such graph? Or Can someone provide me an example to plot using inbuilt apple API'S
Awaiting an answer, Thanks a lot in advance.
You will need to do this inside a custom UIView.
In the drawRect method you can calculate the extent of the x-axis and the y-axis. You then need to draw the axes onto the actual screen with the numbers showing the values.
Then you need to work out how thick each bar should be and how tall they need to be.
Then draw them into their relevant spaces along the x-axis.
Before any of this though you need to give is a background colour. Maybe some guide lines so the user can easily read the values...
Or you can use http://www.cocoapods.org to install CorePlot and it will do it all for you.
It is MUCH MUCH MUCH MUCH more difficult to draw the graph yourself than it is sto spend a while learning how to use coreplot.
I tried using coreplot, but it is a giant framework which is too good and toodifficult for a begineer like me to consume. So I came across OVGraph, which is a basic framework that does all I want, And it is easy to use as well,
something like this :
OVGraphView *graphview=[[OVGraphView alloc]initWithFrame:CGRectMake(0, 0, 480, 300) ContentSize:CGSizeMake(960, 300)];
//customizations go here
[self.view addSubview:graphview];
[graphview setPoints:#[[[OVGraphViewPoint alloc]initWithXLabel:#"today" YValue:#3.2 ],[[OVGraphViewPoint alloc]initWithXLabel:#"yesterday" YValue:#4 ],[[OVGraphViewPoint alloc]initWithXLabel:#"3" YValue:#6 ]]];
generates beautiful graphs.
Another option can be EChart which has EColumnChart
This third party project worked nice for me and I found the design much better than most other projects. Unfortunately is paid, but it's always an option :)

For my client I have to develop a dashboard for the iPad (in Monotouch), showing several charts. Is there a chart component available for MonoTouch? Or does anybody have an idea to generate charts for the iPad?
Thanks,
Danny
There are a couple of commercially available chart components with MonoTouch bindings:
ShinobiControls - have launched a beta of their bindings
Steema Charts - have MonoTouch bindings
I was looking for such a control for charting but haven't found one. I draw my graphs manually. After all it is not so big deal just a bit of math. I draw pies and bar graphs.
