Are there any 2d free rotation tools?

[dx0ddyu]

I'm able to rotate about the origin 90 degrees at a time easily enough. Are there any tools to allow free rotation around some origin? I'm not finding anything!

Or, if I use a 3d graph but constrain it to 2d will this allow free rotation?

thx

Hello,

have you found the Rotate tool? There's an example of it in the Feature Demo you can download from GitHub here:

OK... Like that, perhaps. There are some unfortunate zoom effects in the demo - if I grab to rotate it always also zooms in or out. Have hints on how to still have zoom and also have rotate?

Well, no. I don't think this does what i'd like. It allows rotation around axes that I don't care about. I'd like an x/y plane and I'd like to be able to do free rotation around an arbitrary point like, oh, the origin.

But given what you already have it should be trivial for you to make it do what I want

Of course! But seriously, if you'd like us to give you a quote for the work, do please write to sales@steema.com and we'd be happy to give you one.

It is not trivial getting GDI+ to behave like native 3D canvases (OpenGL, Direct3D etc.), which leaves you with only the Rotate Tool to work with as things are.
