| Research Abstract |
NON-PHOTOREALISTIC RENDERING TECHNIQUES (NPR) IS UTILIZED IN VARIOUS VISUALIZATION TECHNIQUES, BUT RECENTLY THE APPLICATIONS IN THE AREA OF ART AND SCULPTURE ARE INVESTIGED. THE PURPOSE OF THIS PROJECT IS TO RENDER THESE NPR IMAGES BY USING PHYSICAL MODEL RENDERING TECHNIQUES AND TO CODE THESE EXISTING SCULPTURES AT HIGH LEVEL FIRST, BASED ON PHYSICS-BASED RENDERING (PBR), WE DEVELOPED COMPUTER GRAPHICS IMAGE RENDERING TECHNIQUES BY USING WOODEN SCULPTURES, WOODBLOCK PRINTS, COPPERPLATE PRINT AND ESPECIALLY WE DEVELOPED A USER INTERFACE OF RENDER THE WOODBLOCK PRINTS. AND WE TRY TO RENDER THESE WORKS BY SIMULATING PHYSICALLY PROCESS AND PHENOMENON OF HIGH LEVEL ART TECHNIQUES CALL DRYPOINT. THIS RESEARCH IS EVALUATED BY THE SPECIALISTS AT DEPARTMENT OF ART, KYUSHU SANGYO UNIVERSITY AND OBTAINED THE RESULT OF EFFECTIVENESS. NEXT, WE DEVELOPED BASIC TECHNIQUES AND DESIGN OF NEXT-GENERAIION CAR NAVIGATION SYSTEM. WE PROPOSED A NEW METHOD USING AN AUGMENTED REALITY FOR THE CAR NAVIGATION BASED ON FULL CG WITH EXISTING SECONDARY STORAGE. WE DEVELOP TO CONSTRUCT A VIRTUAL WORLD BY CODING FRONT IMAGES TAKEN BY AN ONBOARD CAMERA USING COMPUTER VISION TECHNIQUES. THIS REALIZED A COMMUNICATION METHOD OF REALTIME INFORMATION EFFECTIVELY BY RENDERING IMAGES AT THE SAME GAZE POINT IN THE VIRTUAL WORLD AND DISPLAYING THEM TO DRIVERS. FINALLY, FOR RENDERING NON-PHOTOREALISTIC IMAGES, CONCENTRATING ON COPPERPLATE PRINT, ESPECIALLY MEZZOTINT, WE REALIZED PHYSICS MODEL DESIGN AND IMAGE RENDERING TECHNIQUES. HERE WE TRY TO RECONSTRUCT MEZZOTINT TECHNIQUES HAVING ABILITIES OF VARIOUS GRAY LEVEL REPRESENTATIONS BY TWO KINDS OF INTERMEDIATE EXPRESSION IMAGES. AS A RESULT, WE CONFIRMED THE PROPOSED METHOD CAN RENDER PBR IMAGES IN PHYSICALLY GOOOD MEZZOTINT WORKS.
