Abstract

With the large-scale implementation and application of real-time rendering technology on lightweight platforms, cartoon rendering, as a core branch of non-photorealistic rendering (NPR), faces key technical challenges in contour rendering stability and real-time operation efficiency in lightweight rendering scenarios. To address the problems of contour fracture, dynamic flicker and high performance overhead in traditional depth-normal cartoon contour detection, this study designs and implements a lightweight cartoon rendering and contour optimization scheme based on the Unity engine. Building on traditional detection methods, this scheme integrates edge smoothing and adaptive threshold adjustment strategies**, and optimizes** the rendering process by combining post-processing downsampling technology. It can be adapted to performance-constrained devices such as thin-and-light laptops and mobile terminals, and provides stable and efficient technical support for the engineering implementation of cartoon rendering on lightweight platforms.
