NAME
normalize - normalizes a vector
SYNOPSIS
float normalize(float v); float normalize(float1 v); float normalize(float2 v); float normalize(float3 v); float normalize(float4 v); half normalize(half v); half normalize(half1 v); half normalize(half2 v); half normalize(half3 v); half normalize(half4 v); fixed normalize(fixed v); fixed normalize(fixed1 v); fixed normalize(fixed2 v); fixed normalize(fixed3 v); fixed normalize(fixed4 v);PARAMETERS
- v
Vector to normalize.
DESCRIPTION
Returns the normalized version of a vector, meaning a vector in the same direction as the original vector but with a Euclidean length of one.
REFERENCE IMPLEMENTATION
normalize for a float3 vector could be implemented like this.
float3 normalize(float3 v) { return rsqrt(dot(v,v))*v; }PROFILE SUPPORT
normalize is supported in all profiles except fp20.
