A rendering algorithm for visualizing 3D scalar fields

  title={A rendering algorithm for visualizing 3D scalar fields},
  author={Paolo Sabella},
This paper presents a ray tracing algorithm for rendering 3D scalar fields. An illumination model is developed in which the field is characterized as a varying density emittter with a single level of scattering. This model is equivalent to a particle system in which the particles are sufficiently small. Along each ray cast from the eye, the field is expressed as a function of the ray parameter. The algorithm computes properties of the field along the ray such as the attenuated intensity, the… CONTINUE READING
