isInfinity alias isInfinity = isinf: query if any entry is inf
isNaN alias isNaN = isnan: query if any entry is nan
isValid alias isValid = isvalid: query if all entries are not nan and not inf
vec2 alias vec2 = Vector!(float, 2): Pre-defined vector types

cross genType cross(in genType a, in genType b): Vector cross product
distance genType.valueType distance(const genType a, const genType b): Distance between two vectors
dot genType.valueType dot(in genType a, in genType b): Vector dot product
faceforward genType faceforward(in genType N, in genType I, in genType Nref): Flip the Vector N based on an incident vector I and a reference Vector Nref
length auto length(in genType v): Vector length floating point valueType
normalize genType normalize(in genType v): Vector normalize
reflect genType reflect(in genType I, in genType N): Reflect the Vector I on a plane with normal N The normal N must already to be normalized
refract genType.valueType refract(genType I, genType N, genType.valueType eta): For the incident vector I and surface normal N, and the ratio of indices of refraction eta, return the refraction vector The input parameters for the incident vector I and the surface normal N must already be normalized

isVector template isVector(T): If T is a vector, this evaluates to true, otherwise false
