Hi there(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to project some 3D points on to the span of two orthogonal vectors.

v1 = [ -0.1235 -0.9831 0.1352]

v2 = [ 0.7332 -0.1822 -0.6552]

I used the orthogonal projection formula

newpoint = oldpoint-dot(oldpoint,normal(v1,v2))*normal(v1,v2);

but when I plot it in matlab I dont get the points projected onto the plane.

Any ideas were I am going wrong?

Cheers

Duane
