How do I create this type of effect with an image? I'm wondering how to get the thick edges and the tilted look. Is there an online tool that will convert a flat image to look like this?
If you want to recreate the image using Photoshop, you could do something like the following (please excuse my very quick and poor example!).
Many designers have already created PSD files using Smart Objects that you can use to accomplish this "isometric 3D" style (thanks to Tom here).
All you need to do is replace/add your image or design to the Smart Object layer and that's it.
1. Download a PSD File To Use As A Starting Point
There are plenty out there, here's a list of the ones I tried:
Pixeden has good resources too and for a minute thought about purchasing one of their PSD (which are very well built and designed), but once I found the above free resources... you know the rest.
2. Create Your Own Isometric 3D
In this example I'll be using the Perspective Screen MockUp PSD file I recommended above in item #1.
After that is up to you to add your own style to the isometric.
Here's a video that shows you how to create your own isometric for business cards using Smart Objects. Amazingly simple: https://www.youtube.com/watch?v=DZF0HnipaZ0
I would recommend using the Illustrator perspective grid because it allows you to easily maintain and edit things on a plane.
Here's a very quick example I put together:
I recently answered a question dealing with the perspective grid that also included some further reading links at the bottoms. It's a great tool to read up on if you're serious about doing vector-based perspective work.
