The article is devoted to the creation of a model of the light source with the complex character of spatial, angular and spectral distribution and integration of the model to method of bi-directional stochastic ray tracing with photon maps. The developed program interfaces allow integration of the models to any kind of stochastic ray tracing simulator. The designed algorithms of the light emitter allows physically accurate calculation of direct vision luminance component and components of direct and indirect light illumination for the method of the bi-directional stochastic ray tracing with photon maps. Examples of photorealistic images of scenes illuminated with light sources represented as a set of rays illustrate the article.
Keywords: stochastic ray tracing, light source, direct light source visibility, primary luminance, secondary luminance, photorealistic visualization.
