I use Sketchup which is about as close to drawing as you can get, well all this fancy VR stuff might beat it now
I think you could cheat, the Zeppelin scenes where originally rendered as 6 images which you can convert to a spherical image, you could simply put the image on a sphere with a camera in the center and spin the camera, it would take seconds

But it would look skewed, no? Technically you could do the same thing with photoshop too or maybe with one of the sprite part applications that have mesh warp support, such as Spine.

Either way 2D rotation wouldn't look as nice as actual 3D rotation of a room, but you could probably get away with it if you added motion blur.

When the images are converted to a spherical it'll look right on a sphere, panoramic engines use a cube and shaders to get ride of shadows, mapping a sphere is easier but for a tour or game its a bitch to add hotspots or whatever to a sphere a cube is a lump easier.
Most 3D game engines use a sky dome for the environment


it looks skewed but would render fine on a sphere
