Tutorial 16 - Texture Mapping in OpenGL

[@SuperToughnut]

Need more opengl tutorials. You're good at this.

[@cloverd3742]

This video is from 2013?? Still very helpful for my computer graphics class in 2020. You explained the concepts very clearly. Thank you so much!

[@TheDa6781]

came here from Cherno's channel and I must say, you rock. Cherno is more interested in how his hair looks than to explain things properly. Good job man.

[@foxcm2000]

Excellent tutorials! It really helps to tie together individual bits of the OpenGL API so that we can see the connections between them.

[@fda_premier]

Benny It has not been a tutorial for 2 years. I want to take this opportunity to thank you for your effort to explain and pass on your experience with OpenGl C C ++. Thanks for your attitude in helping people, come back soon on the channel. Thank you.

[@jeffchastine]

I'm glad you've enjoyed the tutorials, and thanks for the compliment :)

[@NeevekEst]

The explanation is clear, amazing tutorial. Thank you Jeffrey.

[@jeffchastine]

At the end of the day, it doesn't really matter; others may chime in on their personal preferences, but I avoided compressed file formats (e.g. JPG) just to keep things simple.

[@DrHofstadterFPS]

Absolutely amazing tutorial! Thank you Jeff!

[@jeffchastine]

+DrHofstadterFPS My pleasure - Glad you enjoyed it!

[@DrHofstadterFPS]

+Jeffrey Chastine Hey Jeff, could you share the source code in your (code) videos? There wasn't a obvious link to it. It would make a great study material!

[@rsethc]

This has been *extremely* helpful, thanks!

[@sannoah3492]

better explanation than my cs graphics teacher! thx for this video!

[@jeffchastine]

Glad it helped!

[@badunius_code]

Fun fact: top-left corner of the texture is 0,0 not 0,1. Also to make texture repeat itself one have to specify it, not get it for free.

[@munamajeedlaftah2561]

please what is the difference between uv and st

[@yeseniavelasco4841]

I wish you were my teacher !!!!! .

[@fda_premier]

[@WS-lv4kk]

Are the UV coordinates vertically flipped (V axis flipped) for OpenGL, or is it just me?

[@Septimra]

Just because I want to take the long way to ensure I know everything possible I want to write my own PNG and BMP loaders. But for OpenGL BMP is better than PNG? What if you need to distribute the file?

[@buzen247]

How do I map texture to a sphere ?

[@buzen247]

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

[@TheWeepingCorpse]

Creating you own PNG loader will take weeks or even months of work as it's non trivial. Best to use one of the many open source libraries already available.

[@lolololololololol11]

More OpenGL videos, please!

[@riverfire6068]

will you create any opengl tutorial in the future?

[@jeffchastine]

Honestly, I'm not sure! These tutorials take a lot of time :)

[@fisslewine1222]

So glad to see some tutorials for open gl; are you following a book and will there be tutorials for modern open gl? As I'm having issues changing the textures on instances.

[@jeffchastine]

Nope - no book! I created these to cover the basics, so they should be able to accompany just about any book.

[@fisslewine1222]

Jeffrey Chastine Do you have tutorials that cover modern open gl 4.2+

[@任安明]

I got one. It names "Computer Graphics Through OpenGL From Theory to Experiments". The author is Sumanta Guha.

[@fisslewine1222]

安明 任 thanks I was using her earlier books, which is quite good, but had little for modern open gl

[@gapi274]

which librarys do i need to include, i have freeglut and it says GL_BGR was not declared

[@jeffchastine]

Are you using my code base and getting that error? I used freeglut...

[@gapi274]

maybe we have diferent versions of the freeglut

[@jeffchastine]

The only thing I could think of is a what your graphics card does/doesn't support. Check out www.opengl.org/discussion_boards/showthread.php/122861-GL_BGR

[@gapi274]

thanks i found the problem i think...

[@mohamedmlayah2959]

i swear that i didn't understand anything almost how to load the image

[@jeffchastine]

It's because KZbin is adding in extra characters (like the hyphen in the word "Primitive"). I'm posting it here as two parts: htp://cse.spsu.edu/jchastin/courses/cs4363 followed by /summer2011/labs/Primitive_Geometry.html I hope that helps!

[@huzaifakhan_771]

2:54 what on earth?

[@sayekz]

Jeffrey Chastine fucking Nice explanation!

[@jeffchastine]

From the OpenGL side, you wouldn't. This would be done in Maya/Blender/3DS (or whatever) and would be information that comes as part of the model's file. However, if you want to do it manually (which is possible - I've done it), you'll have to write the code to generate the UVs. I wrote some code in a lab a few years ago (that I *think* is right), but check out: htp://cse.spsu.edu/jchastin/courses/cs4363/summer2011/labs/Primitive_Geometry.html

[@buzen247]

Do u mind to confirm the URL. Thanks

[@remuss7]

You can use SDL(much,much,much better than GLUT) and use SDL_image.h

[@jcweaver1990]

Why did you create a new channel?

[@FeelingShred]

I disable mipmapping on all games I play, never seen one that looks acceptable in my eyes

[@walterisraelmoscosozarate8768]

You explained Meshes Generacion

[@30.0sec]

awesome
