Building material product rendering method and system

The invention discloses a building material product rendering method and system, and the method comprises the steps of carrying out the material manufacturing of a building material product through employing a physical rendering method, and obtaining a basic color map, a roughness map, a metal degree map, a normal map, and a transparency map of the building material product; and calculating and displaying the real rendering effect of the building material product according to the basic color map, the roughness map, the metal degree map, the normal map and the transparency map of the building material product. According to the invention, the material manufacturing and physical rendering methods of the building material product are combined, the rendering effect of the building material product is further calculated and displayed, the actual characteristics of the building material product, such as the basic color texture, roughness, metal degree, concave-convex feeling, transparency, etc., are added through th
