Adds `penetration_vector` to the `epa_result` struct to represent the direction and magnitude of penetration.
This allows for more accurate collision response calculations and simplifies access to penetration information.
Updates both the early-exit and iterative EPA calculations within `epa_algorithm.hpp` to compute and store the penetration vector, factoring in the relative origin of the colliding meshes.
Reorders the transform application to translation, scale, then rotation.
This ensures the collider’s world matrix is constructed correctly, preventing potential scaling or rotation issues in the GJK algorithm being developed on this branch.
Updates the mesh collider to include a scale parameter, allowing for non-uniform scaling of the collision mesh.
This provides more flexibility in defining collision shapes and supports a wider range of scenarios.
Removes the separate `Simplex` class and integrates its functionality directly into the `GjkAlgorithm`. This simplifies the code and reduces unnecessary overhead.
Updates tests to align with refactored implementation.
Adds GJK algorithm implementation for detecting collisions between mesh colliders.
Includes mesh collider definition and unit tests for basic collision detection.
Provides a foundation for more complex collision handling and physics interactions.
