PROFILE
Emil Wallberg
Over five months, contributed to the OpenSpace/OpenSpace repository by building advanced black hole visualization modules and enhancing rendering fidelity for astrophysical scenes. Developed CUDA-accelerated GPU rendering pathways and integrated C++ and OpenGL-based shader systems to support both Schwarzschild and Kerr black hole models, including runtime switching and parallax-enhanced star fields. Improved asset management through consistent naming and profile configuration, while refactoring shader and rendering components for maintainability and numerical stability. Focused on code quality and reproducibility, the work enabled more accurate, flexible visualizations and streamlined CUDA build integration, supporting future research and development in high-performance computer graphics and simulation.

Apr 1, 20252025-04 OpenSpace/OpenSpace: Delivered Kerr Black Hole modelling and rendering enhancements and star field improvements. Implemented foundational Kerr model integration with CUDA-based ray tracing, rendering improvements including accretion disk shading, and numerical stability improvements. Star field rendering improved via kd-tree scaling for accurate star positioning. Shader reliability and resource management enhancements including fixes to shader domain, perfect hash lookup, and refactoring shader program pointers to unique_ptr. Result: richer, more believable black hole visuals, more stable rendering pipeline, and a clear path for further physics-based features.

Feb 1, 2025February 2025 OpenSpace: Implemented the Black Hole Visualization Module within the OpenSpace rendering pipeline, delivering a CUDA-backed GPU rendering pathway and establishing essential rendering components. The work covers initial module integration with CMake, headers, and sources, along with texture rendering, shader setup, and camera-driven rendering surface. A refactor of the black hole renderable improves maintainability and paves the way for future feature expansion. CUDA build setup and integration groundwork were established to support performance-critical rendering workflows.
