草图到 3D 转换（创意品牌片）

A car sketch on paper. The camera slowly pushes in. Pencil lines lift off the paper, gaining dimensionality, color, and reflective paint, transforming into a photorealistic 3D sports car driving on an open coastal highway. Scene: late afternoon golden light over a winding cliff road. Light: warm rim from the sun, cool fill from the sea side. Camera: a single continuous push-in that becomes a low tracking shot alongside the car after the transformation. Style: cinematic premium auto commercial, photorealistic CGI grade. Audio: pencil-on-paper scratch transitioning into a deep V8 hum. Constraints: stable car identity, no watermark, no Logo other than the sketched mark, no warped wheels.
