How does Pirenesi compare to Studio Artist 2 ?
Will it work with a series of images like in an animation? NRR is very popular but I tried it with a client and they didn't like it, they prefered the photorealistic look.
I'd say there's almost no relation. I just checked out the SA 2 web site - and its a very exciting product that my artist friends would probably love (if they were on a Mac) ... but it is basically a flatland painting program, super-sophisticated that it is.
Piranesi's strength is that all tools can be aware of and react to depth as well as the geometrical orientation of surfaces in an image. This is because it operates on EPix (Extended Pixel) files that contain a depth map, a material map, and an RGB image.
This means that if you want to insert a photomontage (cutout) of an oriental rug in a room, it will appear underneath the chairs and tables, properly scaled and in perspective. SA2 has no such knowledge AFAIK.
If you want to paint a moulding around all of the visible walls in an image, Piranesi will scale and skew the moulding to retain perspectives.
You can take a picture of your client, mask it out, and then insert it into the scene and have it scaled automatically as you move your cursor around the scene to decide upon its location.
Even after you've painted and added cutouts, you can have Piranesi generate reflections in surfaces...because, as before, it is aware of the geometry necessary to calculate them and to mask appropriate elements in the scene.
Much more of course... but the above are examples that are photorealistic, which your clients prefer.
For non-photorealistic work, since Piranesi is aware of the 3D geometry, brush strokes or etchings can automatically keep the same relationship to planes, much as you might sketch or paint by hand...in one step. In a paint program, you have to manually paint each surface to get the same effect.
Depth based gradients are also pretty cool - both for photorealistic and non-PR images. These can be used to darken or lighten distant hallways, create fog or other ambience effects, create depth-based blurring or other filters and much more. So interactive and fun ... but not possible in an ordinary paint program that isn't depth and material aware.
Piranesi can paint in a 2D mode (frontal) and operate with just 2D images (which you can convert to have certain types of depth behavior), and while brushes can be defined by any image that you might create in Photoshop/etc and there are a multitude of blending modes, textures, filters, and automatic (algorithmic / monte carlo) painting options ... there isn't the full richness of painterly things that appear to be in SA2.
Piranesi won't work with an animation - no rotoscoping.
