Abstract: The paper presents a frame work of interactive walkthrough in 3D scene and focuses mainly on the implementing techniques of walkthrough in 3D space, including walkthrough by keyboard, walkthrough along path, recording path of walkthrough, converting video to files, collision detection. The problem of dithering when walking along the linear spline path and reaching a corner is solved. These techniques have been applied in the developed system and do well.
