摘要： The invention relates to a method and technical equipment. The method comprises receiving media content comprising images and depth information; generating a sparse voxel octree from the received images and depth information; projecting the received image colors to each voxel of the generated sparse voxel octree based on visibility; converting the received images into a set of radiance samples for each voxel of the generated sparse voxel octree; processing the radiance samples by performing one of the following: fitting the radiance samples to a parametric color model to generate estimated radiance samples for a current viewing direction; or analyzing the radiance samples with the content of the generated sparse voxel octree to separate an actual surface color and reflectance properties from a reflected lighting.
