: Is there any program I can use to draw in a 3D environment? I recently tried out Tilt Brush (on Vive), and I'd like to draw something like that. I found that Blender's Grease Pencil tool

@Sarah814

There really exist some 3D design software and real 3D input devices for them. One example:
www.geomagic.com/en/products-landing-pages/haptic
Computer screen gives very limited realtime feedback of what you actually are doing. The linked device uses haptics to get over it. It means that the device feels like your'e working on 3D surface. It can be used with specially designed drawing and sculpting software.

This is premium stuff, so all I have seen are only advertisements.

You can not actually get a 3D drawing done with a 2d device. Since obviously that device only draws in a plane and you would need to project things onto something.

So all applications that you have a painting tool in 3D will suffer from same not designed to paint in 3D. As this isn't a limitation of the tool itself but the input and output device attached. A 2D device is limited to drawing on a projection of some kind.

The grease pencil is not a unique tool though. Most, DCC* 3D applications have a similar tools. Grease pencil is meant to annotate your animations. For example Maya has paint FX which can do quite a bit of complex shading and accepts tablet pressure etc. And it was meant to draw in 3D. But again the input device is limited to 2D so you can not arbitrarily paint in stuff in 3D

* DCC stands for Document Content creation and means graphics suites as opposed to CAD applications.

It's not simply a software issue, if you want to draw in a 3D environment using a common computer you need a 3D input device such as a 3D mouse.

You could still use Blender with something like the Space Mouse.
