Piranesi's patented '3D painting' is founded on a number of key features which make it easy to develop stunning 3D images quickly.

	Locks: Piranesi allows you to 'lock on' to a particular portion of the image. These locks mean that you do not need to create masks in order to limit your painting actions to a particular feature in the scene - Piranesi automatically detects the edges and does not paint beyond them.
	Painting in perspective: When you paint with textures - such as brick or wood effects - Piranesi uses its knowledge of the 3D geometry to continuously adjust the texture to honor the scene perspective.
	Cutouts: Piranesi uses the term 'cutout' for 2D raster images or 3D models which can be placed into the scene, such as people, plants, trees, furniture, or cars. 3D models can be in 3DS, DXF, SketchUp, ArchVision RPC, or MicroGDS format.
	Non-photorealistic effects: Piranesi is an especially valuable tool in early design stages. In these stages many details are not known or can be too expensive to model, and with Piranesi they can be easily tackled and achieve the desired results. Piranesi's non-photorealistic effects give you the edge of 3D with the traditional presentation and style of those early design stages.
	Styles: Effects or combination of effects - locks, cutouts, textures, fades, blends, and so on - can be saved as a style for future re-use. Piranesi comes complete with a whole range of predefined styles, using over 2000 free texture and cutout images. A Style Manager is provided to help you manage your styles and create new ones.
	Plans and Elevations: You can use Piranesi without ever building a 3D model! Piranesi allows you to import any plan or elevation image to use as a starting point. Many of Piranesi's effects will work without depth and material information. Because Piranesi knows that the image is plan or elevation, depth and material information can be added by constructing new planes and adding cutouts. Piranesi will let you begin with any PNG, TIF, BMP, or JPG image - all you have to do is tell Piranesi whether to regard it as a plan or elevation. Many of Piranesi's effects will work without depth and material information. Because Piranesi knows that the image is plan or elevation, depth and material information can be added by constructing new planes and adding cutouts.
	Panoramas: Piranesi breaks new ground by introducing animation to non-photorealistic rendering. Panoramic views can be rendered with Piranesi, and saved in .MOV format for display using the industry standard Apple Quicktime® viewer.
