i have 2 3d vectors. (objects x, y , z float values) in diagram below, determine length of green line. distance along vector 1 vector 2 is. or, distance origin end of line on vector 1 @ 90' vector 1 , passes thorough point @ end of vector 2. i doing in unity3d have access quite few helper methods enable me length of vector3 , on easily. the length obviously norm(v2)*cos(angle(v1,v2)) and since cos(angle(v1,v2))=abs(dot(v1,v2))/norm(v1)/norm(v2) the final formula is abs(dot(v1,v2))/norm(v1) one e1 = v1/norm(v1) is unit vector in direction of v1 , , green vector is dot(e1,v2)*e1 resulting in same length formula.

this question came mind, , don't know how figure out. let me show mean: int x = 1; auto lambda1 = [x](){ // x, not specified here though } auto lambda2 = [](int x){ // x, not specified here though } lambda1(); lambda2(x); let's assume have either lambda1 or lambda2 @ given time. which function faster in case? pretty sure difference minimal, if there difference @ all, caught interest , i'd know! this might stupid ask if working 1 int, there might measurable difference in larger scaled lambdas. the first 1 translates to struct _ { int x; _(int x_): x(x_) {} void operator()() const {...} }; the second 1 translates to struct _ { _() = default; void operator()(int x) const {...} }; the former may have various effects* around closure construction site, latter may have same effects* around closure call site. * - depends
