OpenGL Room Demo

[avielMenter]

Agreed rungAaz, that's largely what's important. I can't say much about how OpenGL compares to directX in its rendering power, but DirectX isn't cross platform which means I won't even bother learning it.

[1tZn0TS34n]

it looks like minecraft with tessellation

[superkellerman8D]

Very nice! I wish i had a graphics card that supported more than opengl 1.4... Intel mobile doesn't make the best cards...

[fatbubble123]

that is very impressive.

[nitro404]

Hahaha, I love the leaning camera. Good old silly camera issues from keeping track of too many rotation values.

[manish9mati]

nice work!!!!!

[hornetpalooza]

Well done.

[monstercameron]

doesnt parallax suck performance?

[NASk8er4778]

@its0nah- It's not really a question of difficulty, so much as the fact that OpenGL 3.0 wasn't designed with innovation and forward thinking in mind. I'm sure many OpenGL enthusiasts will hate me for saying it, but DX11 did win out against OpenGL in that respect.

I can only hope that the Khronos Group learned from their mistake and future revisions will improve. But back to the video, I'm deeply impressed! Hopefully the programmer will release the source code, so newbies can learn from it :).

[MGBoney]

@NASk8er4778 thanks mate :) The code should be uploaded somewhere on my personal website but need to find the link, it's old stuff. The relief mapping shader is just a straight port from Cg (the shader code is in the original relief mapping article) to GLSL so it's easy to find it online

[M43k0]

please, tell me how much time this took you to programm, or didn't you programmed it from scratch?

[MGBoney]

@M43k0 a couple of days, I just reused an engine I wrote before , added new FX and rearranged the scene. To write the enmgine took a couple of weeks, so from scratch it would have taken 3-4 weeks I guess?

[its0Nah]

i dont know much about 3d graphics api's but why most developers use directx when opengl is clearly better?

[NASk8er4778]

@its0Nah - Google OpenGL 3.0 mishaps and I'm sure you'll see why. Please note, I am a huge fan of open source, but I am deeply disappointed with what the ARB & Khronos Group let out the door.

To cap it off, no OpenGL is not better. It's not necessarily worse, but it's certainly not a better API, unless your a CAD developer :P.

[its0Nah]

well, i wouldnt get it, i'm barely starting to learning C lol, how is it not better though? is it harder to work with or something?

[its0Nah]

@MGBoney Amen dude.

[MGBoney]

@its0Nah Actually I prefer DirectX much more for a lot of reasons. But at the end once you know a 3D API and understand how they work they are all the same. This demo is written in OpenGL because at that time I happened to have this engine ready (I did it for an MSc assignment) and wanted to release a new demo ASAP for some job hunting. But seriously, leave all the stupid DirectX vs OpenGL thingy to fanboys and start coding stuff yourself. It's time spent in a much better way :)

[acf2802]

Nice. Too bad the parallax mapping doesn't self shadow, you can clearly notice the flat shadow of the sphere on the ground.

[Damnshid]

Does Relief Mapping form a real Geometry?

[cyborgtroy]

No, only displacement mapping affects the geometry.

[zamliman]

Very nice, will try to make something similar =)

[GodDCreator]

nice!

[RungAaz]

OpenGL is much better than DirectX

[Vleesball]

nope..

i was wondering what was better week ago and i read a f***ing 10 page article about it :o

directx is way better dude.. openGL can bearly keep up with directx these days.

[RungAaz]

ok you may be right but OpenGL works on several platforms

DX does not

[majorhavoxg1]

Doesn't matter, DX can work on Linux in wine and cedega. Besides, Parallax mapping is no longer viable since it eats performance like a fat gelatinous blob.

[RungAaz]

anyway i hate DX somehow.

[cyborgtroy]

And in WINE it gets translated to OpenGL... badly.

[salmiak911]

Vleesball, Dx is not better...

It does only run on Xbox and Windows.

OpenGL on the other hand runs on PlayStation, Wii, Linux, IPhone, IPod, Windows and on many, many other platforms. It would be better if microshit didn't go their own way and stayed on the OpenGL ARB.

[Vleesball]

So in your opinion... since DX is owned by MS.. and that it doesnt run on ps3 / wii.. it isnt better :s ???

Thats stupid -.-

[majorhavoxg1]

Name a decent opengl game that isn't a port from DX9 that came out recently.

OpenGL lacks all the technical support that DX offers.

An Equally good openGL engine takes 3 times as long to make as a DX9 engine does.

[RyanPridgeon]

How did you do the ball's shadow?

[iFeelNoSorrow]

WIN!

[DusteDdekay]

Damn, that's really good! :)

[surudika]

awsum ^^

[drummerzhans]

Bump mapping, noice! Dude, 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.

[JurisL85]

Awesome! what FPS you get there ? and how long it took you to write this one?

[MGBoney]

around 75 fps using an NVidia 8600M GT, I spent about a week (not full time) writing the demo, but the render engine was already implemented from a previous demo

[petropotato]

Posting a list of any papers that you used as reference would be nice.

[Tetrix03]

amazing ceiling and general bump

[endre1989]

Nice:)

[robmaister12]

if only half life 2 had this...

[surudika]

ye :P

[FUNNYCOWY]

Ehh, it's cool but this is just copied and pasted code/pictures you found. They look cool but aren't hard to implement since people have already released everything needed to just paste it into your project. I don't know how much of it you really wrote since it has all been done. It's a great start though for a game/graphics engine.

[MGBoney]

lol

copy/pasted code/pictures? Have u read the code before talkin? Send me a private message if u want the source code so u can have a look.

[AndyGoRAWR]

I'm just saying all the shaders have been released and the textures you used other people made. I still love how everything looks though and would love to see you continue working on making this.

[darkuran]

Hey, could I see the source please?

And would it be OK with you if I incorporated this into an engine that I want to use for my game(s?)

[MGBoney]

hi, sure, just send me a PM with your email address and i'll send you the code

[iiiears]

What about particles? Were there any modifications to physics?

[MGBoney]

This was a graphics demo, no physic based modeling at all.

Check out my "OpenGL Box Demo" for some particle dynamics

Cheers

[iiiears]

Wow - self reflecting shadows. Almost raytrace quality.

[MGBoney]

basically relief mapping is a simplified ray tracing, I check the ray intersections with an height map instead of doing the check with an high poly mesh

Check out the paper "Real-Time Relief Mapping on Arbitrary Polygonal Surfaces" for more info

[TrojanxInfection]

Thi looks really good...and is this on mac? I'm fairly new to computers thnx.

[MGBoney]

thank you

no it's a windows application

[rappybas]

Great!

[amcadam26]

really nice work, pay no attention to the guy saying it's rubbish, especially since he's got no videos of his own.

[RossKilgariff]

Great work, seriously.

[Krisando]

:P its nice, not rubbish!!

[oblongoblongoblong]

this is rubbish

[idinev]

nice :)

[jorocaro]

Wow... pretty amazing man!!

you're the best!

I hope to be like you someday.. hahaha

bye man!

[cypher1554R]

The bumps with self shadowing and light reflection look nice.. Well done..
