Template-based scattering illumination for volumetric dataset

Volume data encompasses the intricate internal details of objects, offering a canvas for rendering translucent aspects. However, pursuing realistic lighting in volume rendering requires substantial computational resources. We propose a method that capitalizes on the shared scattering patterns found in similar materials, allowing us to create templates that store these patterns for specific materials, facilitating efficient rendering. Derived from material properties, these templates enable the faithful representation of scattered light without imposing a significant computational burden, regardless of the volume data’s scale. This approach ensures a clear depiction of material characteristics and light scattering in the resulting images. The swift generation of templates, achievable within 30 milliseconds, empowers real-time adaptation to changes in lighting and materials, making them a valuable asset for exploring data from multiple perspectives.
