Piranesi is a specialised '3D painting' tool allowing you to start with a simple rendering of a 3D model and quickly develop it into high quality images ready for client presentations. You can use Piranesi to quickly develop photorealistic images,by painting in textures and scenery with automatic perspective and masking; or you can use Piranesi's wealth of effects to generate non-photorealistic images that have a more subtle,hand-rendered feel and focus the client's mind of what is important in the design. You can even use Piranesi with a 2D plan or elevation image,or to generate Panoramas!
