These are two photo-realistic architecture renders made by Alex Roman. Other examples can be found here. The quality of light and texture make the renders look like photos. I admire 3D computer renders such as this one because they make the viewers feel like they are in the space, looking at the building. They emphasize the details of the building, qualities that people might miss. I think the algorithms that rendered the works might be linking color and light intensity together, using different colors to describe the quality of light. The algorithms might also be using the size of pixels to describe the smooth/roughness of materials. The artist can choose to express a specific quality of the building or the vibe he/she wants the viewer to experience.
