The Blobs Go Marching Two by Two

Listing 2. Finding the Intersection Point.

void FindIntersection( tVector *a, tVector *b,
float aVal, float bVal,
float thresh, tVector *result)
{
/// Local Variables ////////////////////////////////////
    tVector diff;
    float ratio;
////////////////////////////////////////////////////////
    VectorSubtract( a, b, &diff);
    ratio = (thresh - aVal) / (bVal - aVal);
    VectorMultiply( &diff, ratio);
    VectorSubtract(a,&diff,result);
    if (aVal > bVal)
}
