This technique opens ray tracing up … Weband refraction. Our image-space method allows for varying the line style and also supports ray-traced reflection and refraction. 3 OUR METHOD Our goal is to augment a ray-traced image with lines along cer-tain features: object silhouettes, intersections between objects, and creases (i.e. regions of high surface curvature).

Ray Tracing Primitves with Toon Shading and Feature Lines

WebFreeStyle is an edge- and line-based non-photorealistic (NPR) rendering engine. It relies on mesh data and z-depth information to draw lines on selected edge types. Various line styles can be added to produce artistic (“hand drawn”, “painted”, etc.) or technical (hard line) looks. Thanks to the EEVEE engine, the gap between offline and ... WebRay Tracing Primitves with Toon Shading and Feature Lines By Emily O'Neal - CPE 473 - Fall 2024. Description: For my final project I added NPR style rendering features to my renderer. I added toon shading and feature lines on both spheres and meshes. To accomplish the toon shading, I added an extension to my original phong diffuse calculation.
