Visualization in scientific computing technology can be used in architecture industry and related field, to transform three-dimensional data into images, and assist architectural design，construction, decoration, urban planning, etc. Its effect is very good. In this paper we first introduced the concept of visualization in scientific computing technology, and explained its basic methods and application areas. Then we discussed its application in the architecture design, construction ,decoration, and urban planning, and analyzed its future development prospects. Reasonable suggestions have been pointed out to promote the effective application of scientific computing visualization technology in architecture industry and related field.
