@cmuratori I never really considered the fact that linear algebra wasn't really a thing in the early-mid 90s for pro-programmers. it's weird

@cmuratori@sssmcgrath I would wager that in, say, 1990, _most_ game programmers did not know why/how they would use a dot product. -
@cmuratori@sssmcgrath A fair number would have had an unrelated class in college about it, but it would have been out of context. - Show replies

@cmuratori@sssmcgrath Must have been an exciting time for it. Today I spent 8 hours against my will wrangling async calls in javascript.Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori didn't Abrash go to school for physics or something math-y? I guess linear algebra in general didn't have much emphasis put on itThanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori I can't wait until we all ditch classic linear algebra for geometric algebra.Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori@sssmcgrath When I first learnt rotation in the 90s, no matrices, just trig operators. -
@xDirtyPunkx@cmuratori@sssmcgrath hah yeah, it was just some 'magical' formulas being passed around

@cmuratori@sssmcgrath ??? I think you're referring to this, but this is not about the dot product per se... http://www.jagregory.com/abrash-black-book/#rotation-by-projection … -
@cmuratori@sssmcgrath (the column/row vectors of a matrix having geometric meaning is, sadly, something a lot of LA courses fail to cover.) - Show replies

@cmuratori@sssmcgrath My first tri-xform code (~96) used Euler angles, fsin/fcos and wrote over the same vertex array every frame :)Thanks. Twitter will use this to make your timeline better. UndoUndo
