<0> does the glory hole really belong on the top 10 human inventions list?
<1> http://www.elitebastards.com/cms/index.php?option=com_content&task=view&id=110&Itemid=29&limit=1&limitstart=3 actual improvements in opengl
<1> ati high end cards
<2> ok
<2> I need some help
<2> What the hell? seriously?
<2> I have CCW front face enabled
<2> and cull backface
<2> i'm trying to render a skybox
<2> drawing quads
<3> u got the winding correct?
<2> winding?
<3> yeh
<3> i think that matters
<2> my first vertice is the bottom left corner, -1000, -1000, -1000, the second is 1000, -1000, -1000, the third, 1000, 1000, -1000, the fourth -1000, 1000, -1000
<3> ie you define clock or counter clockwise
<2> yea, I called glFrontFace (GL_CCW);
<2> so anyway, this quad renders
<2> right in front of me
<2> I want to put one in back of me
<2> Can't I take those same coordinates
<2> and make the -1000 z's into 1000?
<3> i've got some code which renders a skybox
<2> its still counter clockwise, isn't it?
<3> would that make things easier?
<2> naw, I know how to render a skybox, i'm just wondering why the hell these coordinates aren't working
<2> isn't -1000, -1000, 1000, the second is 1000, -1000, 1000, the third, 1000, 1000, 1000, the fourth -1000, 1000, 1000 CCW as well?
<3> no idea
<2> ...
<3> i wouldn't really worry about front or backface culling with only 6 quads, tbh
<3> hopefully you should always be inside the skybox.
<2> yea....
<4> make sure its within the clipping range too
<2> I pop and rotate
<2> theres seams on the edges though
<2> :\
<3> GL_CLAMP_TO_EDGE
<3> or sommit
<3> #define GL_CLAMP_TO_EDGE 0x812F
<3> ok
<2> for texture settings/
<3> i got a question ..
<2> ?
<2> nevermind, those coords I listed aren't CCW
<3> anyone done ***embly for opengl ?
<4> like glsl ***embly?
<4> or just x86 or something
<3> well ARB ***embly
<3> GLSL is bit different, it compiles on load
<3> but probably translates
<3> i got a TEMP variable
<3> and it contains the colours of my fragment
<3> so RGBA
<3> i want to add up RGB and stick them in say the R part of a TEMP variable
<3> how can i do this ? :p
<2> ah
<2> the damn skybox has edges
<2> bastards!
<2> didn't want me to see it was seamless
<3> skybox -> http://extraball.sunsite.dk/notepad.php?ID=20320&parse=c
<3> enjoy
<2> I don't want your evil code.
<3> its nice code
<3> u just call the CreateSkyBox with the x/y/z coord you want it centred on
<3> then give it a width/height/length etc
<3> eg, CreateSkyBox(0,0,0,1000,1000,1000)
<3> skybox at origin with lengths 1000 :p
<2> its skybox code
<2> anyone can write skybox code
<2> why not just pop and re-rotate ?
<2> heck.. no need to even pop. render it before everything else, even before you translate.
<2> but after rotation.
<3> u talking to yourself? :]
<2> sure
<2> I guess
<2> if nobody was listening
<5> what does a double pointer do ?
<5> Uint8 **pixels;
<0> it's a pointer to a pointer...
<3> think 2d array :p
<6> but beware, int i [2][2] is a 2d array, but very different from an int**!
<5> :)
<4> debugging geometry ****s
<7> Unit41: A pointer gives you a level more in abstraction when sending variables on the stack. A double pointer can be ***igned the adress of a double pointer, or point to a pointer.
<7> Or, it can allocate space to hold an array of pointer.
<7> Or allocate space to hold pointers which also gets allocated space, making a 2D array.
<7> To change a variable's value inside a function, you will need its adress, hence you use a pointer.
<7> If you want to change a pointer's adres, you need a pointer to that pointer, and so on.
<7> You 'should' really know this before even peeking at libraries and APIs let alone the OpenGL API.
<7> It's mandatory C and C++
<8> now he knows ;D
<7> People who start out with OpenGL without proper knowledge of the language they are using, annoy me.
<3> everyone has to start somewhere :p
<7> Yes. And the start is called "learn to walk before you start with bicycling"
<3> i always jump in the deepend, normally always end up learning lots of useful stuff along the way
<7> Sure. It's not our buisness what means people use to learn themselves new things.
<7> But doind that AND ask for help on IRC is just ignorant and respectless.
<7> It kind of shows that you are lazy, in a hurry, and just want things to work instead of learning.
<7> Why would people waste their time to help somone like that?
<7> someone*
<3> rant over ? :)
<3> take some chill pills :p
<3> i dont care, they can ask all they want dont have to reply
<7> dukey`: You are the one tossing fuel on the fire..
<3> i better go back to idling
<9> some people don't use C or C++ for OpenGL purposes :P
<10> o rly?
<3> java opengl ^
<9> scheme is good, mm'kay
