Most people believe I'm weird. Moreso the teacher when I handed in my assignment and told him that I'm managing matrix state changes without saving the state of the matrix in question (IE: no push/pop). Instead I use loadMatrix/multMatrix for all animation and it works perfectly, even under complex scenes. My question is whether it's common to forego the push/pop matrix stacks in favour of loading/multiplying? Some of the techniques I use within my scenegraph are unorthodox. This isn't the first nor last I created my own method which is considered strange by everyone except myself but it is a method in which I'm confused as to whether it's done commonly or is it just me behaving badly. Thanks.

the methods loadMatrix and multMatrix are in my point of view not so performant like just push/pop the matrix but if you havnt problems with the speed at all, there should be no problem using this instead...

The way you handle the matrices depends on the way you traverse the scenegraph.
If you just traverse it from top to bottom, push/pop can save you a bit of processing (very little), if you sort your render commands by shader / texture / back to front for blended one, etc.. push/pop are not that usefull.

Anyway, if you manage cleanly your matrice stack on the CPU, I don't think that you will get any performance boost with push/pop.
