How I can draw the blue line?   Reply With Quote

2. if you have normals of A and B pointing to one direction, then blue line direction will be (n(A) + n(B))/2  Reply With Quote

How I can determine normals direction relative one another?  Reply With Quote

4. On the 2nd thought, you can also do this with direction vectors themselves. Assuming you know some two points on A and B, you have d(A) = (A - O)/|A - O| and d(B) = (B - O)/|B - O|, then d(C) = (d(A) + d(B)) / |d(A) + d(B)|  Reply With Quote

I dont understand mean the d(C) - what is it?  Reply With Quote
