Predominantly used in NPR or 'non-photorealistic' rendering, Piranesi also works well adding effects and interest to photorealistic images as here, in a beautifully detailed image by Jacek Mielewski, an architect at MAAG in Warsaw, Poland.
ArchiCAD
Piranesi support is included in Archicad 8.0 R3 and later on Windows, and from Archicad 9.0 on Mac.
To save in EPix format, ArchiCAD saves a rendering, rather than the 3D window, so the PhotoRendering Settings need to be reviewed first.
In the PhotoRendering Settings dialog, Size & Background, set the Resulting Image size to the final resolution you need, for example 3000x2300 pixels. Click here for a screenshot of the PhotoRendering Settings dialog.
Other rendering options may be useful, such as anti-aliasing. Then from perspective view, choose Save As, Piranesi EPix and click Render. Click here for a screenshot of the Save options.
Note: if you do not have the INT or US version of Archicad, the Piranesi EPix option may not be shown. In this case, it may be possible to copy the Piranesi add-on from the English folder to the folder for your language.
