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.
Accurender
On Windows, AccuRender 4.0 is able to generate EPix files ready for use by Piranesi.
After a rendering is complete, select the File > Save rendered image as command on the AccuRender menu. Choose the Piranesi EPix image(.epx) format.
Notes:
a) Three point perspective is supported, but not two point perspective.
b) The Piranesi interface is available in the full AccuRender 4 product only.
