We present in this paper a production-oriented technique designed to visualize contact in real-time between 3D objects. The motivation of this work is to provide integrated tools in the production workflow that help artists setting-up scenes and assets without undesired floating objects or inter-penetrations. Such issues can occur easily and remain unnoticed until shading and/or lighting stages are set-up, leading to retakes of the modeling or animation stages. With our solution, artists can visualize in real-time contact between 3D objects while setting-up their assets, thus correcting earlier such misalignments. Being based on a cheap post-processing shader, our solution can be used even on low-end GPUs.
