i commented out linux compile and had it compile for mac instead, but i got an error i wasnt sure how to resolve. took it to my friend who codes (i dont really) and he couldnt figure it out either...

ANY Suggestions you have are appreciated (i'm stuck)

Thanks in Advance!

here's a copy/paste of the End of what the terminal spat out:

I ask just for curiosity.
Is there a clean mathematical way to solve the following problem?

There is a Mathematical weakness if a edge line points directly in the center.
So if the two points of a edge are in a straight line to the center (0,0,0).

I speculate, it is the reason for the noise used in Animate::Animate(), to prevent that edge lines point directly in to the center.

Animate::Animate () {
...
    noise0 = 0.005f;
    noise1 = 0.0005f; 

For example:
In this code part the resolut for n b is infinite/NaN, because r3_norm(N) and r3_norm(B) result is 0, if the edge line points to center.

inline float stereo_project (const Vect& x, const Vect& dx, Vect& y, Vect& N, Vect& B) {//projects a tangent vector : R^3 >--> S^3 --> R^3 to normal vectors 
...
    float n = scale / r3_norm(N);
    float b = scale / r3_norm(B); 

Or the Edge tube of such edges gets wobbly because it misses the adjustment.
