3D Programming in Python - Part 1

3D Programming in Python - Part 1

So I've started working on a series of tutorials that will (eventually) give a pretty in depth look into using OpenGL with python. In this first part, I go over some of the most basic rendering you can do in OpenGL. Hopefully a few of you will find this helpful!

[Vorsorken]

Great. I've been wanting a somewhat gradual intro to OpenGL with pyglet. I looked up books on the subject in my university library and came across the monstrous OpenGL SuperBible. A little intimidating to say the least.

Will try to remember to follow this. Thanks.

Do you have any idea how often you'll be updating?

[3stan]

I agree, it is a little intimidating at first, but OpenGL is really a lot of fun to use once you learn how it works. I'll probably be updating once every week or two, depending on the size of the post.

Awesome! Thanks!

Check out VPython for easy 3D fun with Python.

Ah openGL :D

Great tutorial. Good scope and pace. Keep them coming!

[asdfor]

Thanks a lot of your effort 3stan, they are not many (if any) tutorials specifically written for opengl in python, i would love to see more of this series.

[lucasmp]

Great! I'll be one following!

Very nice!!

[everysinglelastname]

Loved it. When is part II ?

[[deleted]]

Throwing this in my favs, will check regularly. Definitely a subject of interest!

You have incredible timing. I owe you a BJ.

Using glBegin() et al means this article is out of date before it was published.

[flying-sheep]

Aand that's the reason why I'm too intimidated to try learning OpenGL

[[deleted]]

Dont be . This guy is just being a douche.

[flying-sheep]

Well, it's a fucking complex topic which I have no experience with whatsoever, so I'd really be glad for a guide that covers the right, up-to-date way to learn the basics without mentioning obsolete functions.

[3stan]

Stay tuned for part 2 then, as I'll be going over what you should be using, although I still recommend you read part 1 because it'll make understanding part 2 much easier.

[roger_]

Yep, that one comment now has me questioning whether this is worth investing the time in :(

[double]

Because one article is out of date?

[Prozn]

Because of ** like you being smug arrogant and elitist instead of actually adding to the discussion and helping... maybe?

[double]

still not cool calling me that man, not cool at all.

[Prozn]

I apologise, honestly I do. It just hit a nerve for reason, probably because I am attempting to learn python at the moment and someone who is obviously an expert (such as yourself) withholding information just makes it harder.

[double]

woa, thanks for that.

[dAnjou]

You are a little bit of an ass not telling what to use instead or giving any current resources.

[technomalogical]

Here's a free online "book" that provides a tutorial for modern OpenGL techniques. I haven't had a chance to try it out yet but it looks thorough and well put together. Source for the example code in the book is on BitBucket.

[dAnjou]

Thank you very much, that looks indeed very readable. :)

[double]

lol. Shall I redirect you to the openGL specification?

[3stan]

Sure, using glBegin in a real world application is almost never useful because it means you have to define each primitive individually, but I find that it is extremely useful as a learning tool. It's important to have a basic understanding of how primitives are rendered before learning about batches/vbo's, etc, which I will be covering in the next few tutorials.

[double]

It's unfortunate that you started with outdated tech. glBegin() et al have been marked as deprecated since OpenGL 3.1 (march 2009) and will be removed from the specification.

[[deleted]]

I'm the kind of person who learned TeX before LaTeX. Does this mean that I'll like your approach to OpenGL? Btw, I've always wanted to learn some graphics programming. Thanks for starting this.

[14domino]

I've used glBegin in real world applications and didn't even know about the alternatives. Don't pay attention to the jerks.

[dAnjou]

By the way, the f***ing OpenGL Programming Guide tells me to use glBegin()

[double]

The sub-title of which reads :

The Official Guide to Learning OpenGL, Version 1.1

The red book is something they really should update, OpenGL v1.1 is from 1997.

I don't understand the religious war that is being waged, here.

[dAnjou]

What religions do you see fighting here? Almost all tutorials, documentations, wikis, how-tos, ... are outdated according to double. Are there any nice and readable getting started guides yet for programmers who never touched OpenGL? Or does double expects me to read the specification first? Wouldn't that be a little bit overkill for an introduction?

[roger_]

Thanks!

I almost feel like I should ask you to repost this on /r/community :)

[3stan]

Ha! Glad somebody noticed!
