    Workarounds are bad. Terrible, like goto. Workaround=Doom of the world. Workarounds will kill us all.
    No offense but you really don't know what you are talking about. Even if something is mathematically correct there's such a thing as, let's say it together now, floating point inaccuracy. Even in your most beloved and advanced first person shooters they have to develop methods for getting around this. For example when splitting your move into fractions when checking a BSP tree for collisions the idea is to check the fraction of the total move from the starting point to the plane, then from the plane to the endpoint. However, it always actually checks EPSILON units in front of the plane from start to the plane, and then from EPSILON units away from the plane on the other side to the endpoint. Download the quake2 source, open sv_world.c and search for BACKFACE_EPSILON. Also, directly from the quake1 source:

    // 1/32 epsilon to keep floating point happy
    #define DIST_EPSILON (0.03125)
    EPSILON is usually 1/32

    The limit in my engine for the camera rotation was PI/2 radians (directly up or directly looking down). That worked except for the fact that you could look straight down and move backwards because the view vector projected onto the XY plane introduced floating point inaccuracy and allowed it to be projected in the opposite direction (and no gimbal lock was never a problem).

    No ...real... offense taken, but you may have noticed a few smilies in my post. They were there for a reason =)

    There are games like Descent where it is no problem. Is it that much work to rotate the world the last few degrees instead of the camera? Anyway, I don't know what I am talkin about...

    graphics programming is officially my thing, so, like, understand I had to correct you and provide evidence

    I'm trying so hard to actually become the novice wannabe that grew up to become a good game programmer. i don't like being corrected even if you are right, but imma digest you if you're wrong in any way

    With that attitude it will be much much harder to learn, that and you seem like a pompous dick. Accept people's input and judge it in an unbiased manner, they aren't attacking you, your mom, your sister, or you dogs honor, they are giving you advice from what their standpoint dictates.

    I agree with you on the "its not a workaround" part, but you saying that just kinda irked me.

    How long have you been working with OpenGL? I've been working with it for a bit now learning from "OpenGL Game Programming" but I haven't gotten as far as you yet, it looks good. I'm working on a tile based RPG right now heh. I'm gonna move on to FPS some time...

    Smile

    as if you actually took that SERIOUSLY...I've learned a lot so obviously I don't really have that attitude. However I'm not loaning any of my hard earned experience to you for calling me a pompous dick. In fact that is borderline asinine that you insult me and turn around and ask for advice. I've got a real computer game to be working on (I'm sitting in san jose with a group of real developers) so I'm going to be going to do that.

    EDIT:


    and for a side tidbit your beloved carmack said he had an 'ammoral arrogant attitude about being smarter than other people'. If you don't believe me read masters of doom, or better yet just go googling or something.

    I didn't ask for any advice, I said it looks good to balance out me calling you a dick. I don't mind a little pride in one's work, but when you refuse to take other's suggestions and you think you are better than others, that starts grating on my nerves. It's better to be better than you think than thinking you're better than you are.

    As for Masters of Doom, is that worth reading? I was going to buy it but instead I got a book on 3D modeling (figured it'd be better to learn programming than read about my "role model").

    buy it and find out for yourself

    stop reading into things so seriously, I guess I keep forgetting not everyone is like me (i.e nothing is ever serious enough to get negatively worked up over).

    I'm posting this against my better judgement:

    There does seem to be an air of superiority in most of your posts.

    yours and carmack's crap smells just as bad as anyone elses.

    When you talk to Silvercord you can't take everytihng seriouslym but it seems everyone does. I seem to be one of the few people who find humor in things he says.
    Give me a bad reputation!!!

    Thank you Sean.

    Yeah, I'm better at graphics programming than most (if not all) of you guys, but whose fault is that. It's kind of stupid to make stupid suggestions to someone who knows more than you...BIG STUPID FACES!

    Basically, deal with it.

    Just need to stick up for the man himself.

    "Carmack was cocky, but if someone could teach him, he wasn't going to let his ego get in the way. On the contrary, he was going to listen and stick around."
