Outline of Final Research Achievements

In a hand-drawn picture, a single object is often drawn from two or more viewpoints, and the object has a shape distortion. The images having such effects are called non-perspective projection images. We studied to represent such kind of phenomenon in Computer Graphics, and obtained the results as follows.
(1)For creating non-perspective projection images by composing real images, we developed the method using an image sequence obtained from simple capturing devices such as iPhone.(2)For the generation of non-perspective projection images from a three dimensional shape model, we developed the real time rendering method, using OpenGL API and GLSL shading language. Our method uses FFD (Free-Form Deformation) to deform the shape to represent the effects of non-perspective projection images.
