3D data visualization transforms comprehension, offering a richer understanding of complex structures and volumetric information. This project addresses the challenge of comprehending intricate 3D volumetric data on traditional 2D displays by leveraging Virtual Reality (VR) technology. Our approach tackles the challenge by implementing the raymarching algorithm using HLSL and C++, coupled with VR development in the Unreal Engine framework. We successfully integrated the raymarching algorithm, HLSL, and C++ within Unreal Engine. Furthermore, our VR-based application includes the implementation of interactive color transfer functions, enabling real-time customization for a more adaptive and user-centric visualization experience. The incorporation of the raymarching algorithm captures intricate self-shadowing details, showcasing a great rendering technique. Additionally, our implementation of interactive color transfer functions introduces dynamic ad- justments, providing users with unprecedented insights and underscoring the impact of our approach in immersive data visualization.
