PROFILE
Andrimalala Rabenja Rakotomaharo
Over three months, Malal Ark worked on the hlrs-vis/covise repository, focusing on enhancing 3D rendering, UI/UX, and VR workflows. He delivered features such as improved navigation, new UI components, and rendering optimizations, using C++ and leveraging technologies like OpenGL and Vulkan. His technical approach included architectural refactoring to simplify node management, per-instance rendering optimizations, and regression-safe code maintenance. Malal also implemented automated QA for VR interfaces and refined visual fidelity through UI polish and event handling. The work demonstrated depth in graphics programming and software architecture, resulting in more reliable, performant, and maintainable user experiences for complex visualization environments.

Mar 1, 2026Month 2026-03 | hlrs-vis/covise: Key focus on rendering accuracy and stability. Delivered View Frustum Testing Improvements with updated frame bounds and radius calculation to enhance rendering performance and accuracy. Removed an unused textured background class to streamline the codebase. In parallel, executed a regression-safe revert of the frame bounds changes to restore prior geometry handling in VSGVruiFrame and VSGVruiTexturedBackground, ensuring stable behavior. Overall impact: improved rendering fidelity and performance, reduced maintenance overhead, and preserved compatibility with existing UI components. Skills demonstrated include C++ development, rendering geometry understanding, regression testing, and careful version control.

Nov 1, 2025November 2025 delivered meaningful UI/UX enhancements, architectural simplifications, and rendering optimizations in hlrs-vis/covise. Key features include: (1) UI Navigation and Interaction Improvements—refined navigation behavior, pointer sizing, scene graph handling, and icon size configuration to improve user experience; (2) Value poti UI Component and Slider Styling—added a new value poti component and adjusted slider text color for readability; (3) VR UI Architecture Refactor—removed dependency on nodePath by introducing an Auxiliary structure to store parent information, simplifying node management; (4) Rendering Performance Enhancement—refactored vertex input handling to per-instance rates for normals and colors, boosting rendering efficiency; (5) QA Coverage—introduced VIVE UI tests in a CAVE environment to validate visuals and interactions. Major bugs fixed include stabilizing navigation behavior affecting view, fixing slider opacity over dial, and minor formatting polish. Overall impact includes improved UI reliability and usability, reduced rendering overhead, and stronger test coverage, enabling faster iteration in VR workflows. Technologies demonstrated encompass C++, VR UI architecture and refactor patterns, per-instance rendering optimization, UI component design, and CAVE-based QA automation. Business value delivered includes smoother user workflows, lower maintenance risk due to architectural simplifications, and more predictable VR visuals and interactions for stakeholders.
