PROFILE
Emil Wallberg
Emil Wallberg developed advanced black hole visualization features for the OpenSpace/OpenSpace repository, focusing on both Schwarzschild and Kerr models. Over five months, Emil integrated CUDA-accelerated GPU rendering, implemented camera-driven and parallax-enhanced star fields, and enabled runtime switching between black hole models. His work included C++ and CMake-based build configuration for seamless CUDA integration, shader development for accurate shadow and accretion disk rendering, and kd-tree scaling for precise star positioning. Emil also improved asset management consistency and code maintainability through targeted refactors. The depth of his engineering enabled more realistic, flexible, and reliable astrophysical visualizations within the OpenSpace platform.

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.
