To Bob Pendleton ->> Can you share your GL doc?

SDL Development

Hi Bob,

I am just a beginner and love 3D stuff but don’t know GL (OpenGL…)
I have lots of stuff to read (more than 4-5 books on OpenGL) but
couldn’t understand more than few pages. Sorry, but I am a lazy
programmer who believe in concentrating on doing new stuff rather
than understanding old complex ones. OpenGl functions alone are
scaring me a lot! And, please don’t tell me about GLUT and Open
Inventor!

I would like to learn 3D programming using SDL + OpenGL but there is
no complete documentation or “Know how to do it” on the same. You
said in a mail posted earlier that you are writing some stuff on
OpenGl. So, if you or any other guy want to share some REAL easy
stuff about OpenGL + SDL for a beginner like me, please help.

Any sample code is welcome too provided it isn’t boring enough :wink:

Thanks a lot.

What kind of code do you want exactly? I get pretty bored at times writing
long endless code blocks that take quite some time to crystalize. So, to
take a break from that boring stuff, I can write small example programs
which would indulge me in some fancy stuff once in a while, and would also
help you out.

I don’t promise anything wild, but yes I can try as I said ;).

The nehe opengl tutorials are very good. They start from the begining
(draw a polygon) and go up to shadows & cel shading. The associated code
is ported to a variety of architectures, including SDL :

As I said, I am writing an article, actually two articles, on using
OpenGL with SDL. They will be published during the next few months.
It can take as long as a couple of months to write an article and it can
take a couple of more months to get it published. Usually It goes a lot
faster than that. If I send you the article before it is published it
doesn’t get published and I don’t get paid.

BTW, have you looked at the nehe OpenGL tutorials? They’re pretty good.

Thanks a lot.

Thanks Bob for the nice quotes.
They and you, are absolutely correct, no doubt.

But,… They don’t help me. I do have NeHe docs about GL
and other stuff, but …

CAN ANYBODY TELL ME WHY GL CREATORS HAD TO WRITE SO CRYPTIC CODE AND
SCATTERED DOCUMENTATION???

I am so irritated by such replies… Please don’t think that I
haven’t tried the stuff you said. After 8 months into OpenGL, I am
not so far away from where I started. SDL is easy to pick up… and
the same I expect from OpenGL.
So, I am going to write some code for myself (and if u people want
it, post message for me on this forum only) but it can take a lot of
time. Based on OpenGL only, the classes will ease down the cryptic
stuff.

No problem about your docs. I will try to manage without them. Sorry
for disturbing you.

Anybody want to help me?

Thanks Stephane, but I have a HUGE collection of GL docs which
includes NeHe tutorials, codes and demos. Though they helped me a
little, they were less boring :wink:

Thanks, but it does not solve my problem.

Hi Nishal,

Thanks for taking interest in my problem. I have difficulty in
understanding OpenGL functions and “what they do”!! Though I have
some books but OpenGL programming is so lengthy and so cryptic to
me, I wish that I could write some C++ classes to ease the stuff
down to the level of SDL. I want to make them as easy as possible
with GREAT readability of code. But to do this, one must be
proficient in OpenGL, and that’s what I am not.

I don’t ask you to do everything for me, but yes, I would like to
ask you to tell me about some important function and structures with
the help of small code samples which MUST BE HEAVILY DOCUMENTED. U
c, documentation of each function is not what I have seen in the
sample codes that most of the programmers write. But of course,
exceptions are always there! :wink:

If you or anybody would like to help me in developing these classes,
I welcome you with deep gratitude.

Please help me.

Thanks,
Nayan

Well maybe OpenGL is not for you. Have you looked GFX engines like OGRE?
This helps to make the code cleaner and besides all modern games are
build around an GFX / Game engine just because nobody want’s to
reinvent the wheel for every game. Making new GFX engine takes many
yeras of development from many coders, so a beginner might do oneself a
favor and just look game / GFX engines that already exists today and
which of these are looking like the most convenient solution to ones
needs. Then simply go through the examples of your choice and learn to
use the engine then you are ready to go.On Thursday 04 September 2003 21:55, Nayan Choudhary wrote:

Maybe you could try something easier than a 3d game for the beginning, like
a 2d game. Then come back to OpenGL after you have improved your programming
skills. At the beginning it’s always difficult to handle a lot of
structures… Keep programming and one day you will be able to master OpenGL
!

They didn’t write cryptic code or scattered documents. The subject is
simply that complex. If you have the “OpenGL Programming Guide” and the
“OpenGL Reference Manual” you pretty much have everything. You may not
be able to understand them, but you have it all right there in only
about 1500 pages of printed text.

I am so irritated by such replies… Please don’t think that I
haven’t tried the stuff you said. After 8 months into OpenGL, I am
not so far away from where I started. SDL is easy to pick up… and
the same I expect from OpenGL.

8 Months? You are this frustrated after only 8 months? I think your
expectations are a little bit off. This is not easy stuff to learn.

I’ve been doing graphics programming (off an on) for 30 years and I
still sometimes have to spend a month reading and researching and
writing test code before I can use some 3D graphics feature that I
haven’t seen before. :slight_smile: Go read “Computer Graphics, Principles and
Practice” by Foley, Van dam, et. al. after that you will feel much
better. :slight_smile: Depending on how much math you have it should take somewhere
between 3 months and 2 years to work through most of the book. Be
warned, it is not a book on OpenGL, it is a book on computer graphics.
Once you understand computer graphics then OpenGL makes lots of sense.

So, I am going to write some code for myself (and if u people want
it, post message for me on this forum only) but it can take a lot of
time. Based on OpenGL only, the classes will ease down the cryptic
stuff.

No problem about your docs. I will try to manage without them. Sorry
for disturbing you.

Like I said, when they are published I will tell the list about them.
You sound rather resentful that I won’t just give them to you right now.
Do you seriously expect people to put you ahead of themselves? Do you
really expect me to pass up a paycheck just to help you?

You’ve been doing graphics programming for comfortably longer than
I’ve been alive. This represents a totally unfair competative
advantage. Expect a visit from WTO lawyers.

30 YEARS? Gah. I’m still tweaking my blitting code…
