21 Calculation of S3D Animations from CAD Models Setting a camera path (foreground, background) Parallaxe max. 1/30 frame size Near and far distance, focal length, base line Modeling a camera rig (SketchUp Ruby plugin S3DAnimin) Duration of animation, frames per second fps 15/25 MOV or AVI (PC video formats), container includes audio and video compressed, codec Xvid Further treatment: mounting, zero plane, stereoscopic window, cutting, audio dubbing Preprocessing: lowest resolution, lowest frame rate, take care of environment setting (fog, shadow) Freeware Stereo Movie Maker 21/24
