In recent years, the use of expressive surface visualizations in the representation of vascular structures has gained significant attention. These visualizations provide a comprehensive understanding of complex anatomical structures and are crucial for treatment planning and medical education. However, to aid decision-making, physicians require visualizations that accurately depict anatomical structures and their spatial relationships in a clear and well-perceivable manner. This work extends a previous paper and presents a thorough examination of common techniques for encoding distance information of 3D vessel surfaces and provides an implementation of these visualizations. A Unity environment and detailed implementation instructions for sixteen different visualizations are provided. These visualizations can be classified into four categories: fundamental, surface-based, auxiliary, and illustrative. Furthermore, this extension includes tools to generate endpoint locations for vascular models. Overall this framework serves as a valuable resource for researchers in the field of vascular surface visualization by reducing the barrier to entry and promoting further research in this area. By providing an implementation of various visualizations, this paper aims to aid in the development of accurate and effective visual representations of vascular structures to assist in treatment planning and medical education.
