minwidth specifies the minimum outline width.

near and far specify the depth range in which the fadeout will be performed. 0.001 on a 1k frame will give 1 pixel edges).Ĭontrols edge thickness fadeout with depth. This can be specified instead of edgefilterwidth. Note that to have proper anti-aliasing on thin outlines, one should use higher PixelSamples.Ĭontrols edge width. This can be a fractional number and can be set to smaller than 1.0 to get very thin outlines.

Table 7.1 contains the list of all edge detection parameters accepted by RiDisplay.Ĭomma separated list of variables to be used for edge detection.Ĭontrols edge width. Example scene available in ` $DELIGHT/examples/toon'.Īdditionally, it is possible to output, in the same display, edges detected on many variables at once (such as depth, normals and any other surface variable). Note how outlines get thinner with distance. For example, one display can output edge detection based on depth variation and another one on surface normals variation.įigure 7.5: Outlines on Oi (opacity) and z (depth). Since 3Delight can output many such displays in one render, it becomes possible to output different edge detection results into different files or framebuffers. All edge detection features are controlled through parameters to the RiDisplay call. This is implemented using edge detection algorithms in image space. 7.11 Rendering Outlines for IllustrationsģDelight has advanced 'inking' features for 'toon rendering' and other illustration purposes.
