Abstract

In the realm of computer graphics (CG) education and development, the lack of versatile and modern tools presents a significant challenge, particularly in providing a comprehensive learning experience that encompasses both legacy and cutting-edge technologies. Traditional frameworks often rely on outdated APIs, such as OpenGL and Direct3D11 or below, which limit the exploration of advanced graphics techniques and hinder the educational process. In this thesis, we introduce pyGANDALF, a powerful, lightweight, open-source CG framework that addresses these limitations through its pure Entity-Component- System (ECS) design. This framework seamlessly integrates an editor layer within its ECS architecture, streamlining the development process for both educators and developers. The framework natively supports two graphics APIs, OpenGL as well as WebGPU, a modern low-level graphics API, ensuring compatibility and versatility across various platforms. This feature bridges a critical gap in educational tools by enabling the use of state-of-the-art technologies such as compute and ray tracing pipelines, enabled by the WebGPU API, which are essential for a contemporary CG curriculum. The framework’s Physically Based Rendering (PBR) capabilities produce stunning visuals, enhancing the quality of both practical applications and educational demonstrations. It also integrates the Universal Scene Description (USD) opensource software, supporting the depiction of robust and scalable 3D scenes composed of diverse assets with complex hierarchies. This fosters highly collaborative workflows and broadens the scope of potential applications. To aid in learning and exploration, the framework includes a plethora of examples that demonstrate a wide range of graphics techniques, from fundamental to advanced concepts. These examples serve as valuable resources for researchers, and developers, facilitating the transition from educational settings to real-world applications. Furthermore, CG educators can enhance CG curricula by leveraging pyGANDALF to efficiently instill modern CG principles to students, a statement that is validated by the expert-based evaluation that was conducted.
