Math

A library providing common linear algebra math operations.

See the documentation.

Features

• Vector (float2/3/4, int2/3/4, half)
• Matrix (float2x2/3x3/4x4)
• Quaternion (float4)
• SIMD optimized (f32x4, f32x4x4, f16x4)
• Euler angles/radians conversion
• Matrix translate, scale, rotate
• Perspective, orthographic projection
• Ray, line, plane, triangle, sphere...
• Axis aligned bounding box (AABB)
• Frustum culling, matrix extraction
• Bounding volume hierarchy (BVH)
• Color conversion (RGBA, linear)
• Version (major, minor, patch, build)
• Hexadecimal string conversion
• Packed vector (1bit container)
• Tone mapping, gamma correction
• Image based lighting (IBL, BRDF)
• Spherical harmonics (SH)
• Enum class flags declaration
• Simplified integer types (int64, uint32, int8...)
• Supports Windows, macOS and Linux
