Updates simplex handling to use references for vertex access, avoiding unnecessary copies. This improves performance and clarity within the GJK algorithm.
Introduces a utility function to create a scaling matrix from a Vector3.
This simplifies the creation of scale transformations, particularly useful for the GJK algorithm implementation.
Updates the `handle_tetrahedron` function to use const references for simplex points, improving efficiency and readability.
Corrects a potential bug where the `simplex` variable wasn't being correctly updated when recursively calling `handle_triangle`.
Also, const-qualifies `point_to_same_direction` for better safety.
Changes the index type for accessing simplex points to `std::size_t` for consistency and safety.
Adds `[[nodiscard]]` attribute to `size()` and iterator functions to signal potential misuse and enable static analysis.
These updates are part of the GJK algorithm 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.
Adds support for different screen origin configurations.
This change allows for more accurate conversion from screen coordinates to world coordinates by correctly handling different screen origin positions (top-left and bottom-left). Includes new unit tests to verify the functionality with both configurations.

Improves navigation mesh serialization and clamping
Ensures correct serialization of navigation meshes by clamping neighbor counts to prevent data corruption when exceeding uint16_t limits.
Updates data types to `std::uint8_t` and `std::size_t` for consistency.
Uses `std::copy_n` instead of `std::memcpy` for deserialization.
Introduces a constants header file for the Frostbite engine,
including common vectors, matrices, and angle types.
This provides a centralized location for defining and accessing
essential mathematical constants used throughout the engine.
Corrects the NDC calculation in `world_to_screen` to improve accuracy.
Replaces custom perspective projection matrix calculation with `omath::mat_perspective_right_handed` for correctness and consistency.
Updates test cases and provides debugging information by printing view and projection matrices.
Addresses an issue in the feature/ndc_invalid_calc_fix branch.
Implements `std::hash` specialization for `omath::Vector2`, `omath::Vector3`, and `omath::Vector4` with float components.
This enables usage of these vector types as keys in hash-based containers, such as `std::unordered_map` and `std::unordered_set`.
Replaces calls to Windows API functions (GetModuleHandleA) with a void pointer parameter.
Simplifies pattern scanning for loaded modules by removing Windows-specific code and replacing it with a generic approach.
Simplifies the PE pattern scanner by removing the redundant `extract_section_from_pe_file` function.
The extracted data is now returned directly from a new `ExtractedSection` struct within the main scanning function, streamlining the code and reducing duplication. This improves readability and maintainability of the PE scanner.
Replaces the custom `view_angle_to` function with `omath::source_engine::CameraTrait::calc_look_at_angle` for vector3 view angle calculations.
This change aligns with source engine conventions and improves code consistency.
Enables users to specify the target section name when scanning a PE file for a pattern.
This provides more flexibility in locating patterns within a PE file, as it's not limited to the ".text" section.
Adjusts the virtual method calling convention based on the compiler (_MSC_VER).
This ensures compatibility and correct behavior on different platforms.
Updates the PE scanner implementation to support both 32-bit and 64-bit architectures.
Leverages `std::variant` and a generic `ImageNtHeaders` to abstract architecture-specific details.
Simplifies the logic for retrieving section data, generalizing the process for improved maintainability.
Initializes infrastructure for PE file scanning.
Adds data structures for PE headers (DOS, optional, section),
including user-defined types for section characteristics.
Refactors existing pattern scanning code to utilize new PE data structures.
Adds basic parsing of PE headers.
Defines `DosHeader` and `FileHeader` structures to represent PE file header information.
Includes definitions for `MachineId` enum and `FileCharacteristics` union.
These definitions are prerequisite for PE file parsing and analysis.
Adds functionality to extract a specific section from a PE file and scan for a given pattern within that section.
Introduces `extract_section_from_pe_file` to isolate a section, enabling more targeted pattern searches.
Overhauls `scan_for_pattern_in_file` to utilize extracted section data and improve accuracy.
Implements a pattern scanning feature that allows searching for byte patterns within a byte range.
Adds `scan_for_pattern` method to `PatternScanner` to locate a pattern within a byte span.
Adds corner case tests to verify functionality and handle invalid inputs.
Adds new test cases to cover additional scenarios for pattern scanning, including tests for leading/trailing whitespace and spacing variations to ensure robustness.
