I am trying to find more explanation of this method but still can not understand it.
It is hard to make sense to me by only semantic explanation.
As far as I found, it is to compute the areas of the orthographic projection of the polygon, but could anyone illustrate this idea?
Thank you so much~
Where did you got this from ? This sounds not very detailed.
The GL wiki seem better :
And this post on gamedev explains that it is the ortho projection for each axis that are taken in account :
Thank you for sharing your information with me.
There is the source I found from Ray-Polygon and Ray-Quadric Intersection Testing
I understand how to calculate Area of irregular polygons in 2D but for Newell’s method, I can not comprehends its principle.
If (A, B, C) are the plane’s normal and Why can we get A by calculating 2 x area of projection onto yz plane?
I just think one illustration can make me understand better.
Thank you again.
