I found wolfram's line-line intersection page and noticed their equation for the time of intersection was rather different to mine. After analyzing the differences, it turns out they produce exactly the same results (when the lines are coplanar), but their method allows me to eliminate one dot product (4->3). Not only that, but it turns out that their method works equally well for skew lines (ie, non-coplanar). mine: CxA.CxA ------- CxA.AxB theirs: CxA.AxB ------- AxB.AxB |
