The original light tracing and backwards path tracing algorithms are both special cases of these strategies. For light tracing, it is connecting the vertices of the camera path directly to the first vertex of the light path. For backwards path tracing, it is connecting the vertices of the light path to the first vertex of the camera path. In ...
Art therapy is a distinct discipline that incorporates creative methods of expression through visual art media. Art therapy, as a creative arts therapy profession, originated in the fields of art and psychotherapy and may vary in definition. Art therapy encourages creative expression through painting, drawing, or modelling.

[1] Tracing can provide a way for a person to develop their artistic skills for example when it comes to learning anatomy. It is however frowned upon in many art circles.
For example, path tracing struggles with caustics from a point light source because it is unlikely to randomly generate the exact path needed for accurate reflection. [4] On the other hand, progressive photon mapping (PPM), a biased technique, handles caustics effectively. Although biased, PPM is consistent, meaning that as the number of ...

[1] The Expressive Therapies Continuum (ETC) is a model of creative functioning [2] used in the field of art therapy that is applicable to creative processes both within and outside of an expressive therapeutic setting.

Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. [1] This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire ...
