line/ ray triangle intersection

Hi All

looking for a reliable ray triangle intersection and point in triangle test alogrithm in 3d. I tried few but they fail the test sometimes…

thanks in advance

Here is a list of all kind of object intersections algorithms, included ray/triangle:

BTW, I highly recommend to buy the book itself:

I like their blog too:

Also, this book by Peter Shirley (which I thoroughly enjoyed reading years back) will explain this clearly:

Realistic Ray Tracing

I actually like the first version better than the second for the primer material up-front.

thanks i’ll implement it and test it
have a nice day

thanks for reply
have a great day
