"Photorealistic renderings" are computer-based graphics or renderings that are so detailed and realistic that they resemble real photographs. These renderings are often used in architectural visualization, product design, game development, and other fields to create virtual scenes or objects that are hardly distinguishable from real photographs. Photorealistic renderings aim to replicate light, shadow, textures, and other visual details as accurately as possible to create a convincing illusion of reality.
Typical features of software in the "photorealistic renderings" domain include:
Physically based rendering engines: The software utilizes rendering engines that implement physically based models for light behavior, material reflections, and shadow casting to achieve realistic results.
High texture resolution: The ability to use high-resolution textures to depict fine details and surface textures in the renderings.
Global illumination and ray tracing: Features for calculating global illumination and ray tracing to generate realistic light distribution and shadow casting that simulate natural light sources and reflections.
Physical material models: Support for physical material models that realistically simulate the behavior of materials such as metals, plastics, glass, and fabrics.
Image editing tools: Tools for fine-tuning renderings, including color correction, post-processing of light effects, and sharpening details to optimize the final appearance.
Interactive preview: The ability to display an interactive preview of the rendering results in real-time to quickly make adjustments and achieve the desired look.
Complex scene management: Features for managing and organizing complex scenes with many objects, light sources, and camera positions.
Support for High Dynamic Range (HDR): The ability to work with HDR images to achieve an extended dynamic range and realistic lighting effects.
