NAME
length - return scalar Euclidean length of a vectorSYNOPSIS
float length(float v); float length(float1 v); float length(float2 v); float length(float3 v); float length(float4 v);
half length(half v); half length(half1 v); half length(half2 v); half length(half3 v); half length(half4 v);
fixed length(fixed v); fixed length(fixed1 v); fixed length(fixed2 v); fixed length(fixed3 v); fixed length(fixed4 v);
PARAMETERS
- v
- Vector of which to determine the length.
DESCRIPTION
Returns the Euclidean length of a vector.REFERENCE IMPLEMENTATION
length for a float3 vector could be implemented like this.float length(float3 v) { return sqrt(dot(v,v)); }
PROFILE SUPPORT
length is supported in all profiles.Support in the fp20 is limited.
