T<----------------------Q
While making a view matrix, I usually cross product a (0,1,0) with W TO GET U W = (T-Q)/||T-Q|| U = (W X (0,1,0)/||W X (0,1,0) v = w x u this works most of the time. But what about when I want to go y axis and look straight down at 0,0,0
What would be the value of the vector? (0,1,0) does not work. Tried every combination even negatives and didn't work.
