C++ solve parametric equations

[RuiQi]

Hello Forum,

Are there any functions that I can use to solve parametric equations ? I need to find the intersection of 2 lines in 3D ( if there is any ).

I know how to do it on paper but am unsure of how I should start coding it on C++

Regards,
RuiQi

If the question is "Does C++ standard library provide such functions?" then the answer is "no".

If the question is "Does some third-party C++ (geometry) library provide such functions?" then the answer is "probably".

However, websearch with "line intersection 3D algorithm" does find several descriptions. Cross and dot products of (mathematical, 3D) vectors are needed, but simple.
