(suggestion: YES) I'd like to add that if we add matrix decomp then we should also consider adding a set function or ctor that takes the decomposed values and constructs a new matrix, so we can easily round trip the conversion (as much as is possible with matrix decomposition). > - should include a lookAt() method? (suggestion: PROBABLY, requires vectors or multiple parameters) Just a note that this is often used in an inner loop and is complex enough that we would get a significant performance benefit from it. ----- ~Chris cmarrin@apple.com
