is a tuple of nine floats (column-major)
Methods
add(a, b)
VECTOR VECTOR -> vector addition
VECTOR SCALAR -> (x, y, z) + s = (x+s, y+s, z+s)
sub(a, b)
VECTOR VECTOR -> vector subtraction
VECTOR SCALAR -> (x, y, z) - s = (x-s, y-s, z-s)
mul(a, b)
VECTOR SCALAR -> vector scaling by a scalar
VECTOR VECTOR -> element-wise multiplication
QUATERNION VECTOR -> quaternion scaling by a scalar
QUATERNION QUATERNION -> quaternion rotates a quaternion resulting in a quaternion
QUATERNION MATRIX -> quaternion rotates a matrix resulting in a matrix
MATRIX VECTOR -> matrix rotates a vector resulting in a vector
MATRIX QUATERNION -> matrix rotates a quaternion resulting in a quaternion
MATRIX MATRIX -> matrix rotates a matrix resulting in a matrix
mix(a, b, s)
SCALAR SCALAR -> simple mix of scalars
VECTOR VECTOR -> simple mix of vectors
QUATERNION QUATERNION -> quaternion rotation spherical interpolation (slerp)
MATRIX MATRIX -> matrix rotation spherical interpolation (slerp)
cross(a, b)
VECTOR VECTOR -> vector cross product
QUATERNION QUATERNION -> quaternion cross product
dot(a, b)
VECTOR VECTOR -> vector dot product
QUATERNION QUATERNION -> quaternion dot product
rotate(angle, axis)
SCALAR VECTOR -> rotation by angle radians along the axis resulting in a quaternion
split(a)
QUATERNION -> angle and axis suitable for rotate
MATRIX -> matrix columns
norm(a)
VECTOR -> vector normalize
QUATERNION -> quaternion normalize
MATRIX -> normalized quaternion derived from the matrix converted back to a matrix
inv(a)
QUATERNION -> inverse quaternion
MATRIX -> inverse matrix
det(a)
MATRIX -> matrix determinant
cast(a)
QUATERNION -> converts the quaternion to a matrix
MATRIX -> converts the matrix to a quaternion
swizzle(a, b, swizzle)
VECTOR -> swaps vector elements
QUATERNION -> swaps quaternion elements
pack(a)
SCALAR -> packed float resulting in 4 bytes
VECTOR -> packed vector resulting in 12 bytes
QUATERNION -> packed quaternion resulting in 16 bytes (xyzw)
MATRIX -> packed matrix resulting in 36 bytes (column-major)
