So you want me to use your method because it's easier - intuitively. Ummm.....lemme think.................NOT!!!!!!!!!!!!!!!!!!!
And I would not attempt a 3D engine if I did not understand matrix math and matrix concatenation. I've programmed all of this before in pure software under DJGPP including rasterization but thankfully now I don't have to.
I thought you were actually catching a flaw in my billboard system and instead I find you are only trying to be right not helpful.
I'm willing to listen to anyone on the board about suggestions they may have. But, in the future, if you do not have a faster algorithm or if you are only posting just to waste my time and bs with me about theory, please refrain from posting.
Please don't talk to me as though I do not understand 3D mathematics or how my own core engine works. I'm not trying to be mean but we posted about 10 posts that eventually came down to the fact that you did NOT have a faster method.
Let me put it this way. I don't care who invented the algo, where it comes from, or if it is original. All I care about is SPEED, pure SPEED. If your algo is not faster, I have no reason to change mine.
Code:
but I think my way is essentially easier and works just as well (although ultimately matrices have so many interesting properties and my way is just a specific way of accomplishing this task)
And what are you trying to say. I am using matrices to accomplish this. I'm altering several matrices to fit what I need. I'm really lost as to what you are even saying.
