<0> is it okay to bind the same texture to multiple texture units?
<1> dukey, sure
<0> gl_arb_texture_rectangle doesn't seem to work with my fragment program :(
<2> Why does OpenGL only allow 8 lights?
<3> it allows as many as the implementor desires.. it mandates an absolute minumum of 8
<3> like I think nvidia actually supports up to 32 simultanius lights?
<2> ...?
<2> i've seen games that have more than 32 lights in scenes
<3> yeah?
<2> I know lightmaps are one way to surp*** the limit
<2> what else is there though?
<3> bear in mind; it's 8 lights PER TRIANGLE
<0> direct lighting using shaders :p
<3> so when you draw, say, a mesh, pick the 8 lights most influential on that mesh
<2> yea but you can only create 8 lightsm a
<2> max*
<3> ogl can do that, too, dookey
<0> the opengl lights only work per vertice
<0> so if your poly count of your level .. or whatever is very low opengl lighting will **** :p
<3> ...
<3> dukey, opengl has had 'shaders' for years now...
<2> hey Erik
<0> thats where per pixel lighting comes in :p
<2> How come the lighthouse 3D tutorial used opengl lights in their per pixel lighting shader?
<3> fragment programs and vertex programs, 'cept I think they call them fragment shaders and vertex shaders these days
<3> I d'no o.O *shrug*
<2> can you do it without the OpenGL lights?
<0> yeh
<2> teach...
<0> although old school opengl lighting will be a lot faster
<2> I don't want old school opengl lighting
<0> it just depends what you want to do
<0> radiosity lightmaps can be much better
<2> per pixel lighting
<2> in real time
<4> ``Erik, I fragment or vertex program are like the ASM version using ARB_fragment_program and ARB_vertex_program. Fragment and vertex shaders use glSlang
<3> ah, thanks for the clarification, fishman
<0> why do so few people do asm shaders? they are very easy
<4> dukey, cause using glSlang is easier if you are used to high level programming
<0> everyone is used to high level programming :p
<3> not really
<4> dukey, and because doing the stuff with fragment or vertex programs doesn't add any performance at all in most cases
<0> if you are programming opengl, i doubt you are doing it in ***embly
<2> by any chance would any of you be willing to help me learn GLSL better?
<0> i'd have to learn it first :]
<0> i only learned asm like 2 nights ago :p
<2> the people I usually go to for help don't know much on graphics programming
<4> exactly, that's why people prefer glSlang over vertex or fragment programs
<2> glSlang = glsl?
<4> Scottc, yes
<4> Scottc, read the specs, read the tutorials and documents available online and if you have any specific question just ask
<2> hahahahaha
<2> Nobodies here! ever!
<4> Scottc, I highly recomend you get the orange book
<2> I don't have 60 dollars to drop on a book at this time, unfortunately
<5> but it has nice pictures
<2> :(
<0> if u wanna learn how to do per pixel lighting, i would suggest understanding the maths first :p
<2> I agree
<2> what kind of maths?
<0> the maths for lighting :p
<2> ...
<0> unless u have no clue about vectors etc
<0> u may wanna start there
<2> I know about vectors
<0> my opengl stereo driver works, im so happy :]
<0> wanna tell everyone lol
<6> what method would i use toi render a scene, but only render what's inside a 400x200 centered box? So that i can pan the rendering to the side and still have a smooth "viewport" in the center of the screen?
<4> specify a scissor rectangle and then enable scissor testing
<6> thank you
<6> works perfectly
<6> ack... I'm drawing 25 tiles and a sprite and it's slowed down to hell. Someone please help. http://rtfm.pastebin.com/777057
<6> it think it's my time logic
<7> morning
<8> good morning
<7> watching formula 1?
<7> man, its been long since i entered this channel
<7> how is everyone?
<7> burga, erik, drnick ;)
<8> i am not a formula 1 kind of guy, i just need to finish my work :)
<7> hehe
<7> what are you doing ?
<8> i want to apply at a company and thus i am working on some application demo with IK and stuff
<8> since i've not worked in the game industry so far...
<7> i see
<7> one of the projects of the company i work at uses IK
<7> its about skeleton positioning
<8> a very interesting field for research
<8> yeah, i am currently doing the basic stuff but plan on adding more advanced technique like 3DSmax' animation constraints (look at, orientation, link, etc.)
<8> to let the skeleton interact with its environment
<8> on a dynamic basis (not preauthored ani)
<7> nice
<7> you aiming at the gaming industry?
<8> yes
<7> good luck :)
<8> heh
<8> thanks
<8> i'll need i suppose... :/
<8> *it
<7> like on anything.. :)
<8> i think i could get unfunny jobs like web-programming, but i'd rather die ;)
<7> hahaha i'd rather die too
<8> ^^
<6> web programming is like the easiest way to make money ever
<1> Must be awfully uninteresting as well
<6> depends on the situation
<6> i've done web programming as work in many jobs
<6> never as my PRIMARY task, mind you
<6> but it's basically like a sysadmin job
<6> there's a lot to learn if you go the extra distance
<3> 'web' is just a funky stateless web api, with hacks to imitate stateful operation... it has the problem of being a dumping ground for uninteresting tasks, though... :)
<1> So many little things to know, so little intelectal stimulation
<3> erm, interface api
<6> it all depends on the task
<6> but i obviously prefer working on my sdl/opengl project =|
<1> I somewhat learned html 3.1 a... couple years ago, I don't know a thing about more recent web stuff :)
<6> i can make stuff work cross browser compatible
<6> but i don't know any of the "right" ways to do ****, i'm sure
<9> oh just you wait until web 5.0
<3> 'html' is the ui interface, drive it with something like php or C or java servelets to get to non-retarded tasks... :)
<3> ruby/rails and smalltalk/seaside look... interesting.
<6> yea
<6> if i was real into web stuff i'd do rails and ajaxy ****
<3> shawnm: check out some seaside and what the two communities say about eachother... it's... amusing :) basically, the seaside guys point out slews of flaws in rails, and the rails guys say "no one uses smalltalk"
<6> politics are so lame =)
<3> heh, the quality of arguments for/against each is interesting... it seems to me that seaside may well be worth a look at *shrug*
<6> when i do web dev
<6> i only have the goal of getting the job done
<6> C++ game type dev is where i explore and learn new ****
<6> i will likely never learn either of the aforementioned technologies =)
<6> although i'm sure a product i worked on could benefit from it
<3> hrm, if you explore and become versed in other languages, your ability in c++ will grow immensly...
<3> you might even learn enough to realize that c++ really really ****s ;)
<3> *duck*
<6> yea i've been learning different languages for like 13 years
<6> i mean honestly
<6> game dev is the only programming that really brings me joy
<6> i'm mostly bored with technology lately
<6> i need to buy a farm....
<6> or a sailboat or something
<3> <-- 23yrs, likes os and compiler/interpreter stuff the most :)
<3> and I've been thinkin' hard about buying a little sailboat, heh :) and putting in another garden box, I miss my veggie garden
<10> <-gfx only
<1> Like this little "Five or more" game in Gnome i have been playing for 2-3 hours
<6> i love Symphony of the Night
<1> Although I should go back to more productive tasks... Erik, any tips of what a raytracing "presentation" is supposed to include if I can't reveal anything technical?
<3> "dog and pony show"?
<3> demos to make people go "oooh ahhhh"
