Talk:Vector
From GPWiki
The wiki is now hosted by GameDev.NET at wiki.gamedev.net. All gpwiki.org content has been moved to the new server. However, the GPWiki forums are still active! Come say hello. I did a major revamp to the "more about planes" section to make it clearer. The Agreed. It is clearer now... and nobody with knowledge of algebra will misunderstand the notation. Ryan Clark 22:52, 6 Feb 2005 (EST) I also fixed a major error in computing the angle from the dot product. John Bolton 19:45, 7 Feb 2005 (PST) the float Angle(const Vector& a, const Vector& b) algorithm is a mess and incorrect. You should clean it up. (i.e. var dotproduct not defined before it's used, and then a value is assigned but not used anymore). [edit] dot productI have noted the two important cases for the dot product - = 0 for perpendicular, and = magnitude(A) X magnitude(B ) for parallel. This can be found in the 2D stuff section. [edit] Removed Vector Notation From ComponentsI removed the vector notation from the components of the vectors. I believe this is the correct way. If you disagree please discuss. |
The Game Programming Wiki has moved! 
symbol looks so much like the cross product that I just replaced it everywhere with standard algebraic notation.
