libsumi

libsumi is a lightweight graphics math library that aims for GLM-style ergonomics while staying friendly to CPU, CUDA, and shader-like code.

Current Surface

• Float vectors: vec2, vec3, vec4
• Boolean vectors and relational helpers: bvec2, bvec3, bvec4, all, any, equal, lessThan, and related predicates
• Matrices: mat2, mat3, mat4 with column-major storage, arithmetic, transpose, determinant, inverse, component multiplication, and outer products
• Common GLSL/GLM-style math: radians, degrees, clamp, mix, step, smoothstep, fract, mod, round, trunc, inversesqrt, pow, atan, fma, and vector overloads
• Geometry helpers: dot, cross, length, distance, normalize, faceforward, reflect, and refract
• Transform helpers: translate, scale, rotate, perspective, frustum, ortho, lookAt, plus right/left-handed aliases where available
• Quaternions: quat, Hamilton product, angleAxis, mat3_cast, mat4_cast, toMat4, slerp, and quaternion-vector rotation
• Texture and procedural helpers: Sampler2D, texture, hash, noise, and fbm
