Piranesi Features
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, such as a specific wall or those parts of the
image which correspond to wooden surfaces.
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. Piranesi
can do this because its Epix format files store a depth and material
value as well as a colour value, making Piranesi quicker to use and more
accurate than traditional painting programs. It combines the ease and
freedom of 2D painting with the precision of 3D models.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
honour the scene perspective.
For example, if you paint with a brick texture, the bricks get smaller
as they get further away, and the horizontal lines of brick courses
converge towards the vanishing points of the scene.
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.
Piranesi's 3D knowledge makes the placement work like magic - Piranesi
automatically calculates the correct size and perspective for the cutout
depending on where in the scene it is placed, and determines masking
effects depending on what lies in front of and behind it. Cutouts can
even cast shadows on other parts of the scene!
Once you have placed a cutout in your scene, you can go back to it later
to tweak its position or change its characteristics.
Non-Photorealistic Effects
Piranesi is an especially valuable tool in early
design stages. In these stages many details are not known, are too
expensive to model, and even if they were modelled would distract from
the important aspects of the design.
Piranesi provides a wealth of effects - many of which would not be
possible without Piranesi's 3D knowledge - to give your image an
artistic, hand-rendered look (they are referred to as non-photorealistic
because the aim is specifically not to produce an image that looks like
a photograph). Such images are often more attractive to look at, convey
a 'feel' for the scene that a photorealistic image cannot, and draw the
client's attention to what is important whilst fading out irrelevant
details.
It is easiest to explain these effects by looking at the resultant
images - the Piranesi gallery contains many examples of photorealistic
and non-photorealistic images.
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.
