Collision & Math Systems

Implemented functionality to generate Oriented Bounding Boxes (OBBs) from transforms, including center, rotation, and extents. This work leveraged existing math utilities while ensuring correctness through comprehensive unit tests (identity, translation, rotation, non-uniform scale, and edge cases).

Expanded into OBB–OBB collision using the Separating Axis Theorem (SAT), where I debugged and corrected issues in an existing implementation to properly compute minimum penetration distance. This involved fixing flawed comparison logic and investigating numerical stability challenges such as epsilon inflation causing false positives after separation.

Vulkan Debugging & Validation Fixes

Investigated and resolved multiple Vulkan validation errors related to API version mismatches between SDKs, drivers, and validation layers. Identified that feature structs were being chained based on the driver-supported version rather than the intended target version.

Implemented a fix that:

• Queries device-supported API version
• Clamps against the requested version
• Gates feature struct chaining accordingly

Validation Layer Edge Cases & Compatibility

Diagnosed additional Vulkan validation issues caused by inconsistencies between compile-time API definitions and runtime validation layers. Addressed feature conflicts (e.g., descriptor indexing with Vulkan 1.2 feature structs) using version-aware preprocessor guards.

Reproduced user-reported issues via targeted test cases that mimicked specific hardware and SDK configurations, ensuring fixes were verifiable and robust across environments.
