"3d software. Like Maya, 3ds max, blender"I was challenged by +Stewart Martin.
I think this one's going to be a real challenge. I honestly don't already know of any GOOD 3D modeling web apps right now so this one is going to take some searching.
I did find and try out shapesmith.net a web based 3D modeler which can be used to print on 3D printers.
I can say that ShapeSmith does well at what it does but it's not a full featured 3D modeler.
|Because the sites screenshots are better than my modeling abilities, this is what the app looks like.|
The app is very clean the majority of the screen is the actual model viewport. I made a basic rocket shape using a cylinder a cone and some rectangular prisms but my modeling skills are not that great so I opted to use the site's own screenshots.
Ultimately the app is very basic and I don't see it being useful for much more than concepting and creating basic 3d models. It is an open source project however and like I said it does what it does well, I would expect this project or a fork of it to become more powerful in the coming years.
