Research On Application Of Realistic And Stylized Rendering Technology In Virtual Lab

Virtual Reality Lab is a three-dimensional virtual simulation laboratory which based on virtual Reality technology and generated by computer.It is an important feature for users to "immerse" and interact with VR lab.Currently,virtual labs in the market are pursuing functional diversity while ignoring the performance and artistic style of the scene.They do not achieve realistic feel of real scenes and cannot give people an immersive experience.Therefore,it is necessary to enhance the rendering effect of the scene.This paper discusses the application of realistic and stylized rendering techniques in the virtual lab scene to enhance the rendering effect.Realistic and stylized rendering technology are both important parts of computer graphics and research hotspots,which are widely used in many fields such as film and television,digital entertainment,industrial design.The realistic rendering technique used the computer to simulate the natural environment and real objects and the realism that rivals the real world is its goal;Stylized rendering technology used computer to simulate the drawing styles of visual arts.The main work of this paper is to apply realistic and stylized rendering techniques to virtual lab and improve the effect.(1)For realistic rendering technology,this paper studies PBR algorithm,then proposed applying it to wall and floor materials which based on traditional rendering and using texture coordinate control UV scaling to improve the material utilization rate;(2)To apply Fresnel algorithm to materials such as glass,display,etc.Then proposed simulating color distortion effect of display screen by inverted Fresnel effect and combined color order adjustment technology;(3)To propose combining Fresnel algorithm to achieve a natural smooth blur effect on particle edges;(4)For stylized rendering technique,this paper introduces edge detection algorithm in engine and applies it to the stroked effect of scene elements.Finally,this paper designs and implements some scenes and interactive functions in virtual lab.The results of rendering effects and performance analysis show that the scheme is feasible and effective,and it also has certain reference value in related fields.
