RaytracingUnte... appears to be an incomplete term and may refer to a project, concept, or product related to ray tracing. In the meantime, this article provides a concise overview of ray tracing and its main variants, to offer context for any specific use of the term.

Ray tracing is a rendering technique that models the way light interacts with surfaces by tracing rays from a viewer or camera into a scene. When a ray intersects geometry, the algorithm computes the light contribution from visible surfaces, including reflections, refractions, shadows, and indirect illumination. This approach can produce highly accurate imagery, particularly for complex lighting and material interactions, but it is computationally intensive.

Key methods include recursive ray tracing, which follows rays as they reflect and refract, and path tracing, which simulates global illumination by sampling many light paths to converge to a physically plausible image. Variants such as bidirectional and distributed ray tracing improve efficiency and realism by exploring light paths from multiple directions. Photon mapping is another technique that stores photon samples to estimate illumination later. Real-time implementations use hybrid approaches, combining rasterization for primary visibility with hardware-accelerated ray tracing to handle reflections, shadows, and occasionally global illumination.

Applications span film production, architectural visualization, product design, and increasingly real-time graphics in games. Core challenges include noise reduction, convergence speed, and resource demands, which are mitigated by acceleration structures like BVHs or kd-trees, denoising algorithms, and adaptive sampling. As hardware and algorithms advance, ray tracing remains a foundational approach for producing realistic lighting in computer graphics.
