Abstract

We present a method to add distorted perspective effects for scenes with a forward camera dolly (the camera moves in the depth direction). Our target scene is a first-person view of the main character traversing a long path. A distorted perspective has been applied to such scenes in hand-drawn animation films to create more dynamic and dramatic motions. Unfortunately, it is difficult to create a perspective for the camera direction in 3D animation. Therefore, we created an interactive tool to design cartoon-like perspectives for 3D computer-generated animations. Users can control the affine transformation, including translation, rotation, and scaling, in the depth direction of the camera coordinate system on a 2D screen. We implemented the proposed deformer on a vertex shader to ensure the real-time performance of our system.
