Research On Digital Vision Video Radiance Performance Of Interior Design Based On Computer Aided Design

An excellent digital sketch is supposed to be measured from several perspectives as follows:excellent vision video radiance, real texture, reasonable picture composition and impacting visual effect. Apart from proficient application of renderer we need to find a theory that can manifest the reality of sketch picture and the said theory is the physical environment in real life. Ideal effect can be achieved only when we learn about the original appearance of objects in real life and master digital renderer fundamental and operation techniques.The thesis takes the basic fundamental and laws of natural light as the departure, which is also the objective reference of digital painting. It further analyzes the light form of natural light source and that of man-made light form and compares the light form in digital painting, thus concluding the usage of different light source and key points of shadow manifestation in the interior. Finally, it proposes the argument that the purpose of sculpting with light in digital painting is to manifest the sense of reality and sense of beauty. To fulfill the sense of reality and the sense of beauty, design sketch are supposed to deal with the method of shadow sculpting, sculpting time and lighting method. Meanwhile, more contagious presentation effect can be achieved by coordinating the color tone of lighting model, color harmony and color mental perception. Researches on light in the physical world and basic aesthetics are crucial to the perfect representation of digital effect sketch. Physical attributes and superficial features of ornamental materials have great influence on the digital vision video radiance of design sketch. Therefore, it takes detailed analysis of properties of various materials in the design process and transfers them to the texture of the renderer to manifest the sense of reality and sense of beauty of the scene. To balance complex color relation and shadow relation, we should pursue the optimum digital vision video radiance by means of coordinating furniture, textiles and design style. Viewpoint in the latter phase of sketching and the composition of the sketch would also affect the digital vision video radiance in the interior.In digital painting, model is the basis and setting off the atmosphere by means of contrast is a key method for the representation of the idea of the designer. The representation of material and environment rely on the reaction between color and light. Taking digital representation of digital vision video radiance in interior design as the object, the thesis carries out theoretical research and program practice by means of VRay for3dsMax renderer which is the perfect vehicle to represent digital vision video radiance.
