OpenGL Tutorial #1: Basic Shapes

[@donnie6680]

I do not care what anyone says for starters but I thank you for posting these videos may God bless you tremendously! Keep up the game design videos from this one I seen your doing great.

[@TheCODTactics]

I am watching this in December 2011. I love you for this.

[@benton202]

i'v been looking every where a openGL tutorial. finally....

[@programmer1905]

wow i went to your website and i loved the tuts, thanks, simply amazing, i was feadin g the book opengl super bible and i dint get it, but with your tuts i really understand what i'm doing, thank you so much.

[@Ryukachoo]

oh HELL yes i've been looking for something like this thank you for individually going through each aspect of the code and explaining the parameters and such, i really was not getting that from my professor.

[@hexkwondo]

Thanx mittrekkie! I have written my first 3-d program! Now I can finally take steps to flesh out my ASCII RPG!

[@zapwow]

I've used Dev-C++ for about a year... I found it easy to set up and get going with, but when I needed more powerful formatting, source management and debugging options Visual C++ was exactly what I needed.

[@sonic2kk]

I'm watching in 2013 and it's still awesome.

[@drederprops]

I am realy pleased by your work and teachings. THANK YOU.

[@Fangornmmc]

@Ilikemustard Lol, so many thumbs up for a comment complaining about this video? Be glad he teaches us this for free in the first place! Also, some people like me just want to dive into opengl without prior C++ background knowledge, a remark like that is in that case very useful. Oh well... @mittrekkie thank you very much for the video, really helped!

[@Zetaeta1618]

It's an API written in C, for use in C and C++. There are many bindings for other languages so you can use OpenGL in them, including ones like JOGL and LWJGL (used for Minecraft) for Java. In general it is the same code, but obviously there are differences based on language syntax etc.

[@Z3r0XoL]

the image quality of this video is amazing

[@rashidswanson]

Great video dude you are helping me in my Devry Online class

[@gribgrub]

@GamingJediPwns - actually you're wrong about that. The handleKeypress() function calls exit. The 'return 0' never gets called.

[@ozone1979]

dude, u ROCK... I just bookmarked ur website.

[@btrekkie]

The code in this program ought to work with any compiler, although you will have to get OpenGL and GLUT set up with Dev-C++ in order to compile and run the program.

[@Fangornmmc]

Well, luckily I am familiar with assembly langauge, I have programmed in it several times and understand the most important concepts (stacks, registers, memory adressing etc). I'll just try openGL and if I am getting stuck ill probably do some research into C. When it comes to programming I just observe examples and learn from those. my goal is usually to get the big lines, the global idea of a language. I might someday really get into one langauge but now I am just trying to do as many as psbl.

[@Fangornmmc]

@Ilikemustard No. In retrospect my comment may sound somewhat harsh towards you, I did not intend that. I was merely suprised that the remark was made. To answer your question better. No I don't have a C background but I do know quite a few other languages. I am mostly self taught but I know basic processor architecture, python ,php, java, visual basic, mysql. I know many languages a little...but I do have a general feel for programming languages.

[@btrekkie]

Actually, according to the GLUT documentation, you're supposed to use unsigned chars and ints. OpenGL functions take GLint, GLubyte, and so on, but GLUT functions use the standard data types.

[@delgadogorn]

I'm new to programming, so does it matter whether you use OpenGL in java or c++? Or is it same code for both? Is it a programming language itself maybe?

[@kludgedup]

I see you have a "From Linux" folder on your hard drive. Dual-boot setup?

[@ramonet27101993]

IS THERE any function in opengl in order to do a hit test? so, fopr exemple, when a car thouches a rock, the car can't cross the rock.

[@Hector-bj3ls]

No. OpenGL just does rendering. You either have to find a library to do that or write it yourself.

[@Ratstail91]

I've been using SDL for input, etc. with OpenGL, should I switch completely to glut?

[@Spirrwell]

@Ilikemustard True, if you want that, go to antiRTFM's C++ tutorials, but it is good to make sure people understand what it is they're doing if they don't know what they're even getting into, especially since OpenGL isn't a good beginner's start. I've been learning SDL OpenGL for the past few days and I want to make the full transition to OpenGL, I don't need the beginner's guide, but it's nice to have.

[@Ilikemustard]

@Fangornmmc Do you have C background?

[@zanshevar]

im watching this in 2013! u rock!

[@GamingJediPwns]

Thanks for making a opengl tutorial but the line return 0; will be reached when esc is pressed because that is how the program will know to return control back to windows. You could also use the macro EXIT_SUCCESS;

[@xazzerr]

How do you get rid of the black console on the background on opengl?

[@scarykidbryan]

Will this work with code blocks environment??

[@EddieVanHalen1977]

This is like eating a really nice meal.

[@MultiGamingGod]

@GenoSkill What should i use for OpenGL i am just starting out, but i am getting a lot of errors when compiling HELP!

[@Vartrex5]

Is visual C++ similar to PHP or Java Script?

[@MultiGamingGod]

@GenoSkill LINUX IT IS THEN but how would i make games with it? is opengl intergrated into linux?

[@skysinbi]

can you tell me whats the difference betweeon using this and DevC?

[@m0nsk1]

I checked your site August 28, 2007. 7:30 PM (GMT +8) and it seems that the website is down. :)

[@4Got10Shadow]

I have question i know this open gl thing but why waste time type lines of codes just to make a simple square if you can made these easily on programs llike maya and 3ds max please enlighten me. is there a way to import the objects in programs like maya to use in c++???

[@btrekkie]

Have you seen the video "OpenGL Tutorial #0a: Getting OpenGL Set Up on Windows"?

[@dannieldefoe]

im watching this in 2017

[@dogdogdogdogdog2546]

Me :)

[@btrekkie]

Yeah, that makes sense. I just figured that "int main" was more conventional.

[@cr1901]

Adding on to @Fangornmmc 's point, I definitely have a stronger grasp of C than I do C++, and I don't recall ever needing to deal with the namespace crap in C... in fact my C++ knowledge stops after basic data structures- I know little of virtual functions, polymorphism, or more advanced C++ topics (learned overloading/inheritance, forgot the syntax former). So for some of us, yes, the refresher is useful. (Note: I'm biased, and NOT a big OOP fan.)

[@btrekkie]

What compiler error do you get? You may want to see my other video on how to get OpenGL set up on Windows.

[@XxDahamonnahxX]

opengl or directx? some people say that directx is better, is that true? and they say opengl doesn't have tesselation, i wanna which is better . plz reply im still a noob at c++ :P

[@007speedcuber]

ah, windows xp! you bring back memories!

[@jeffery12108]

@stingerhead666 Have you downloaded openGL on your computer yet?

[@nexus1g]

Powerful special interest groups (e.g. Microsoft) who have the funds to push their digital crack beyond what an open source project is capable of doing. Ensuring that it is the primary API used means that's what students will focus on. This in turn ensures that studios will continue using DirectX over OpenGL. The wheel is turning, and it will never stop.

[@danielnagy4940]

It's not worked :( Error: GL/glut.h: No such file or directory. What's the problem?

[@delgadogorn]

What does OpenGL do anyway?

[@4Got10Shadow]

@bananavice thanks for enlightening me your a big help.

[@Vartrex5]

Yes but its not like Java or Pascal right?

[@MyStuff774]

Nice tutorial

[@Ilikemustard]

@DonOfTheInternet Meh, I manage to figure out anything I need to do with Win32 using Google and MSDN.

[@radnyx_games]

I am watching this in January 2013. I love you for commenting.

[@alberteinsteinthejew]

I'm watching this in July 2016. Just wanna let you know guys that KZbin is now a subsidiary of Toyota.

[@man122190]

can someone give me the link to download the openGL file..thanks =)

[@benton202]

this doesnt work for me. cant i jus run this without installing microsoft platform sdk??

[@ghostxop2101]

visual studio 08 is free. its only a express but it has everything you need no extras, i still prefer 05 tho

[@4Got10Shadow]

@bananavice I see, but they didnt require me to learn open gl to make a game??

[@benton202]

it gives me compiler error every time i try to compile a OpenGL thng. it sucks

[@darkness9484]

no, u are not the only person. i'm also here ^^

[@btrekkie]

I don't think so. Could you be more specific about what error you're getting?

[@paulthecoolest]

MY college project : a 3d game made on OpenGl..I am simulatenously excited and super scared..Anyone has any experience any tips,any book choices,anything of help note : I have to do this within 2 months..I might get just a few weeks to actually do the programming

[@ViProFL]

why i cant start debugging?

[@kramer3d]

awesome, i love you man :)

[@adikid89]

"kinda lame.. but that's ok.. things will pick up"

[@GsgamesNet]

You didn't put the files in right folders or you didn't use a VS compiler.

[@ItsMrHowTo]

I'm a beginner in coding and I was wondering how I could learn coding cheap and fast... preferring C++ or javascript... without buying big books

[@btrekkie]

Cool, good luck with that. :)

[@Ilikemustard]

@Fangornmmc The comment was made because this is an OpenGL tutorial, not an introduction to C++. Honestly you should not attempt to "dive into" OpenGL without a strong grasp of C, otherwise you will be inflicting unnecessary headache upon yourself. All the languages you listed are very high level, C is very low level (and I specify C because OpenGL is written in C and doesn't use any C++).

[@TheBodysome]

umm should i start a 2013 or something?

[@delgadogorn]

whats " opengl"?

[@renatocanhaify]

What you forget to mention is that Toyota now in 2016 is a Brazilian company

[@benton202]

here is the error it gave me LINK : fatal error LNK1104: cannot open file 'winmm.lib'

[@4Got10Shadow]

@bananavice but i made simple games thru blender without knowing opengl

[@benton202]

never mind this is jus to compicating, do anyone knw of a compiler that already comes with the opengl settings? doesnt have to be free.

[@darkdevil905]

@headchopperz Lol that true mate !

[@anng95]

thanks :) you explain well

[@btrekkie]

Hmm, must've been something with GoDaddy hosting. I know the site has been down at least once before because GoDaddy didn't feel like working. It should be working now.

[@EddieKMusic]

OpenGL does 2D/3D graphics

[@LemonadeCinema]

No Java Script and PHP is usually website development.

[@w9ahmed]

Thank you :)

[@marcusandguitar]

@MultiPivotmasterdx : Yep dude... You can download it from the Official site...

[@rlf1989]

no stick with sdl, its much better or better yet look for SFML ;)

[@iceshadow625]

@MrVirtualCoder it's called learning. no one is just gonna know the basics, they have to learn the basics before they can move forward, simplifying it makes it easier to learn. And once you learn the basics, then you can learn the more difficult shit. You build up. Teachers in elementary don't just bust out with algebra and calculus, they start with basic adding and subtracting.. But I guess any 8 year old that doesn't understand the concept of algebra should just give up on basic math, right?

[@srarlightballs6984]

put void main not int main.you use void when a function returns nothing like main.

[@wesofx8148]

Sometimes you want main to return values for debugging purposes.

[@SeanK-]

void main goes against the C++ specification. VC++ allows it, many other compilers do not. Generally, an application should return success or failure to the OS.

[@ghostxop2101]

cool!

[@ccricers]

Dev C++ is not widely updated anymore. If you want a great free IDE that's quick to set up, get CodeBlocks. Dev C++ looks like a toy compared to CodeBlocks.

[@EddieKMusic]

@headchopperz :DD

[@sacredgeometry]

@CommentMaster12341 I am sure that the whole of the CG software industry would disagree with your comment that openGL was obsolete in 2007, out of date? Yeah sure but it got a severe overhaul in 2008 something you cant really fault the non-time traveling poster of this video. Hindsight is a beautiful thing but it doesn't excuse idiocy.

[@jinjatube]

@DonOfTheInternet Yeah, cos u don't want to actually use the media possibilities of a computer to learn stuff about computer programming, cos that would be like using the tool your going to exploit to learn how to exploit it... which would be, like, er, crazzzy, yeah?

[@roboneko77]

NOW YOU KNOW HOW IT FEELS!!!!

[@TheCODTactics]

I wrote that comment 1 year ago. Wow, I have changed a lot since then :)

[@floralpoboop]

what are you talking about opengl is better than directx, and it has been for years. Its actually ahead by leaps and bounds with more supported functionality, more platforms supported, and stability.

[@6dark6alex6]

I'm watching this in 3654 BC on the Mystical Waters of Ailon

[@krenciak]

I'm watching this in 2024!

[@StelarCF]

O_O you don't like C++? whats the prob with it? And i remember Delphi is some kind of pascal(or not?) Anyway i like C++ :P

[@uc-np7tu]

0:08 When that popupmessage apeared i wanted to close it O_o

[@masterofpop]

yeah right it loaded so fast, this can't be windows that you are using.

[@cypher1554R]

Dev-C++ rules, just go ahead and use it, rather than Bill's crapy toys.. to get the packages, go to Tools -> Check for packages/updates.. and find what you need there.. as for openGL, you can find all the pieces you need: gl, glu and glut libraries..

[@TeronGer]

I go with eclipse, much more usefull ^^

[@Sam-yk5cg]

What gave this video so many views in 2013???
