OpenGL Game Demo

[GeorgePantazis1]

@MGBoney Great job mate....i wonder if you could tell me what i need to know to create a game like that (i mean which programming languages i need). I know some C++ but still i think its not enough....So could you tell me exactly what i need to know?

[GhostXoP]

Lower the resolution, and post another vid in a not so high resolution so we can see it in a non lag way of view

[WallaceGromit88]

Wow, nice work, you're pretty quick to do all this in 6 weeks.

[GhostXoP]

@WallaceGromit88 No not really if you read and pay attention in class

[GumokCZ]

textures on walls are from doom 3 heh

[meming4]

looks like you copied dethelis game

[GumokCZ]

this remands me that old game Descent

[tmwamala601]

If that could be the Great Fox interior, it will be awesome enough.

[ccricers]

Wow, you guys work fast. Then again, the programming class I was in was for art students with no prior knowledge in C or OpenGL.

[blueshogun96]

I need to find some textures like that!

[ChisponGroxo]

Awesome... Remind me Doom 3!

[Senquell]

i am so into the coding stuff! ive learned some visual basic 2008, but its just too hard to learn it home, and i really want to learn openGL, but my IT class is not even close to coding, only really boring stuff that i already know :P but i really want to learn it! btw nice video

[DarkRage4]

start by learnin c++...its complexe but very very powerful...most games r made with c++

[sniperscope20]

What is glsl?

[remco138]

opengl shader library.

[remco138]

im learning opengl myself too, nice!!

joe satriani :-)

[drummerzhans]

I started doing OpenGL and C++ last year, all by myself at home, and im 16 years old. I stopped as it became more challenging for me, I couldn't texture map or create collisions. I got as far as making a camera, map (no texture) which has color blending, giant house, Wired Sphere in which rotates around the whole map. Then i stopped. Couldn't continue by myself. But if i Try to do it again, im capable of remembering every single code that i used.

[remco138]

im 15 years old, i agree that it somehow can be confusing (normals? vectors? never had at math class..) so yeah im trying to make the camera move when you input something (wasd buttons) but when i resize the window ill update the camera then when it should in realtime.

[wiegje]

Hi,

I can answer those for you: Normals are like arrows that point towards where a surface of a polygon is facing. You can use normals to calculate how heavy a light shining on it will reflect on it.

This "normal" is also a vector. A vector is like an arrow in 3D space with a location to where it is pointing, for example (XYZ) 56,32,13.

[remco138]

thank you. :)

so the vector tells how many light the surface will "absorb"?

[wiegje]

Yes. Basically you compare the angle between the vector (direction) at which the light is shining and at which the normal is pointing. If this angle is 90 degrees or more, then no light shines on it. If this angle is 0 then it shines fully on it.

[tnutty2k8]

You have no idea what you are talking about.

[bushidopride]

if you want implement lighting by yourself, yes... but vectors arent only arrows pointing to some direction, usually they are displacements, points, or direction vectors(normals).

[RobotBoy655]

Hmmm... Looks good but needs something like a armor & hp bars, not-unlimited ammo, smaller crosshair, for more difficult game play... =)

[soccergod561234]

what language is open gl based on? c# or c++ or is open gl an entirely new language?

[publicuser3978]

opengl is just a lib, buddy.

[speedaddict2008]

read the description,maybe that will help!

[likizmase]

OpenGl i API just like DirectX or SDL,and you can use c,c++...to work with it.

[publicuser3978]

nice. I was wondering, the rendering appears lethargic. Is that because you intentionally used limited animation, or the program itself is drawing that much effort from memory?

[MGBoney]

no it's because of fraps + high resolution (1680x1050), fps of the video was around 20-25 in some points

runs at 75 fps (with vsync) on a NVIDIA 8600GT + dual core 5700+, 2GB RAM

[baggens55]

@MGBoney You can fraps your own game????????? thats sick

[nierdlord]

I love the graphics 100% I hope that all game makers will move on to opengl! I hate directx! Not comparable to opengl. Nice job!

[cypher1554R]

niiice..

[inricheetos]

How do you do spot/point lights? just GLSL?

[MGBoney]

yeah, using per pixel lights

[BinaryReader]

ever play hired guns for the Amiga 500, some of those textures look like they were inspired from the same game :)

Nice work

[robotwo]

Descent 4 anyone ? :D

[RossKilgariff]

Satch is the man!

[ownagewhentrying]

nice job, just starting to learn c++

[Webking271]

Awesome job on all of the effects.

[jayx1y1x2y2]

i never knew there was a degree for game programming ( also Msc ). That is news.

[Ekeichi]

Great game, great taste in music :P

[subzero1266]

excellent! 6 weeks is less time for a project like this. well done!

[kdeuser10]

NOT FOSS, THAT SUCKS, the guy must of ripped of the code from some game book , which is on sale at Amazon, that's why he is hiding the source ;-).

[MGBoney]

Actually if you spend some seconds of your precious time reading the About This Video section you can see that this is an university project; it's always a nice thing to do to get some information on what are you talkin about before insulting other people's work

cheers

[kdeuser10]

oh. didn't mean to insult. dude the engine seems to be supper. felt so bad that it's not available for FOSW. which is some thing Linux really needs, a good 3D Engine so people can build games. Keep up the good work, please consider releasing an engine for linux under GPL so the whole world would benefit!

Thanks bye

[MGBoney]

Thanks, but unfortunately this "engine" is far from being a complete 3d engine, it's just a demo written in 6 weeks to show some features and I'm not working anymore on it.If you're interested in some good open source 3d engine for linux just search for them on google and you will easily find many good ones (irrlicht, ogre etc...)

bye ;)

[kdeuser10]

Good luck with the Demo ;-)

Bye

[ThunderDonkey]

G3D engine? that texture and depthmap at 3:37 are the same included to the engine.

[xtxmedia]

actually yes, I do charging for any software that is based on free ware such as openGL interface is a felony! its called piracy

[MGBoney]

ah ok you do, so please explain me two things:

who is getting money for this demo? what is a programming api (opengl anyone?)?

cheers

[xXlEdwardoXx]

can i say owned!? lol xtxmedia got owned by MGBoney

[clicshow]

WOW, great job. This engine is open source?

[MGBoney]

thank you :)

No sorry the engine is not open source, I'm using it as a framework to build some tech demos for my portfolio

[xtxmedia]

Mmmm, I wonder if the creators of this know that charging for open source data such as openGL is a major felony.... Mmmm.... Better keep it shhhh!

[MGBoney]

Mmmm, I wonder if you've got any clue of what you're talking about :)
