- **🚀 Efficiency**: Optimized for performance, ensuring quick computations using AVX2.
|
||||
- **🎯 Versatility**: Includes a wide array of mathematical functions and algorithms.
|
||||
- **✅ Ease of Use**: Simplified interface for convenient integration into various projects.
|
||||
- **🎮 Projectile Prediction**: Projectile prediction engine with O(N) algo complexity, that can power you projectile aim-bot.
|
||||
- **📐 3D Projection**: No need to find view-projection matrix anymore you can make your own projection pipeline.
|
||||
- **💥 Collision Detection**: Production ready code to handle collision detection by using simple interfaces.
|
||||
- **📦 No Additional Dependencies**: No additional dependencies need to use OMath except unit test execution
|
||||
- **🔧 Ready for meta-programming**: Omath use templates for common types like Vectors, Matrixes etc, to handle all types!
|
||||
- **🎯 Engine support**: Supports coordinate systems of **Source, Unity, Unreal, Frostbite, IWEngine and canonical OpenGL**.
|
||||
- **🌍 Cross platform**: Supports Windows, MacOS and Linux.
|
||||
- **🔍 Algorithms**: Has ability to scan for byte pattern with wildcards in PE files/modules, binary slices, works even with Wine apps.
