Abstract:
Interactive Rendering combines the geometrical precision of classical computer graphics with the representational freedom of a paint program. It is more sympathetic to the ways in which designers use images, and overcomes many of the frustrations experienced in rendering from CAD models. The scene is generated in a standard viewing application, but saved as a especially enhanced raster image. The extra information allows the Interactive Renderer to apply brushed-on rendering effects which are sensitive to the perspective of the image. Effects can be applied locally or overall, and may be overlaid, blended and erased to create complex combinations. A huge range of treatments are obtainable, both photorealistic and not.
