I'm very pleased to be mentioned inside one of your videos! Very clean and professional explanation, I wish this video was available when I fist tried to implement tessellation shaders by myself, I would have lost a lot less time in trying to figure out all the things :D. Keep up the good work!

[@VictorGordan]

Glad I could use your clip, and good to hear the video didn't disappoint haha

[@tokyospliff]

Thanks again for the deep dive into more complex GL topics. It's probably a bit too specific but I'd love to see one on vertex skinning in compute, or even just had your write to and access vertex data that way.

[@VictorGordan]

Yeah, vertex skinning is very specific, but I might get to it at some point in the future, who knows haha

[@ZFCaio]

Nice to see your channel growing man Your tutorials are high quality

[@VictorGordan]

Thank you! Hopefully I'll be able to start posting more videos soon :)

[@ZFCaio]

@@VictorGordan I understand, we are always so busy, and making videos like this are a ton of work

[@vesae2676]

Great video! If I may suggest one thing regarding the editing: When showing a lot of lines of code you could highlight the lines you are currently talking about (or darken the others) to help guide the viewer's focus on the right things :)

[@VictorGordan]

Yeah, I did that in one of my other videos. This time I didn't because I didn't have time 😅

[@nyxspirited272]

I was learning opengl comfortably until my tutor decided to suddenly be busy.Thanks though.This video helped me out

[@VictorGordan]

Good to hear it's helpful! :)

[@sippingtexastea]

Nice job you just earned a sub

[@VictorGordan]

Thx! :)

[@dhruvil_2662]

Thanks a lottt Mann... This is the video with which I found your channel, can you please guide a way through which one should learn computer graphics ?!

[@VictorGordan]

I suggest starting with my "OpenGL Tutorials" Playlist, it will teach you the basics and a bit more. Then you should just do your own projects, and try some more advanced stuff that I show in my other videos from the Computer Graphics/Modern OpenGL/Procedural Generation series I have :) Good luck on your journey!

[@dhruvil_2662]

@@VictorGordan Yeah, I just started watching your OpenGL tutorials, they are highly informative and addictive as well ❤️. Just love your content bro. Keep pushing such invaluable content, you are highly underrated (ig not for long though 😉) ❤️

[@exhilex]

Miss u on YT man... Looking forward to see ur new video soon! Lots of love to you

[@VictorGordan]

Just having a hard time finding time for KZbin, and I don't currently have any video ideas that I feel very passionate about :/ But I will for sure make more videos in the future. Just not sure when

[@exhilex]

@@VictorGordan Great to hear from you. I hope you find happiness in what you do! And how is your college going?

[@VictorGordan]

I finished uni, I'm now working full-time as a software developer at ASML

[@exhilex]

@@VictorGordan That's wonderful! How is your experience there? What exactly do you work on? (Would love to hear from you on my email or insta perhaps)

[@diamond32tutoriales49]

A good idea is how to import any model with assimp and adding the skeletal animation since there are no tutorials on that or repositories, it would be a good idea to leave the repository as you always do :D

[@artemijspoznaks9584]

Can we have procedural grass tutorial like wheat they use in zelda breath of the wild ? I would love to to know how to do that.

[@mitchellkelly241]

It’s been awhile since your last post is everything okay? Thank you for these amazing tutorials!

[@VictorGordan]

Yeah, everything's good. I was just finishing university so I had to focus on that for a while, and now I'm in the middle of moving places and getting ready for my first job. I will post again, once I have access to my PC and have some free time. So probably in 1-3 months depending on how fast I find a place to rent 😅

[@mitchellkelly241]

@@VictorGordan Yikes good luck with that. I went through a very similar process recently so I know that can be a lot of stress. Take your time returning back!

[@artemijspoznaks9584]

How does tessalation affect uv co-ordinates?

[@DreadDoom]

I see you haven't uploaded in a while; please do more of these! It's so hard to find modern (4.5+) tutorials for OpenGL, and the API is so bloated with deprecated functionality that it's very hard to figure out best practices on your own.

[@VictorGordan]

Yeah, don't worry, I will still upload videos ;) Not sure if I'll make a lot more OpenGL videos though since I'm starting to run out of ideas for it. But I still have plenty of ideas for related subjects like procedural generation and computer graphics :)

[@Lolztrikenamewastaken]

Great Opengl tutorials Can you also make a tutorial about raycasting and Adding animations on Opengl. Thanks if you did.

[@VictorGordan]

Yeah, I'll make some tutorials on those topics eventually :)

[@shadow_blader192]

best tutorials 😉

[@KoltPenny]

When you hear a "In this tutorial" with a soft European accent, you know things will go crazy.

[@VictorGordan]

Hehe :)

[@assum97]

Amazing video! I learnt a lot with this! I have a question: do you have the full code somewhere?

[@VictorGordan]

Yeah, there should be a link in the description to gitHub :)

How can i add a new element to my own project using ur opengl guide? I added new vertices and new indices, new VBO, EBO, VAO, but now i see only 1 object. Can u help me?

[@VictorGordan]

Do you draw both objects? 😅 You need one draw command per VAO pretty much

Can you do physics pls 🥺

[@VictorGordan]

I might at some point in the future!

[@VictorGordan]

Sorry, I've finish university and started a job, and had to move countries twice. And now I don't have that much time with work... I will continue to make videos, but I'm not sure when the next one will be. I need to find something I'm really excited to make a video on...

Hello ı am game devoloper my goal is render milons triangle I have rx 550 gpu 8gb ram ryzen 7 3700x in open gl I am using unshaded non shadow materials my best vertex count is 10 millon But I need more any tips or advice

[@VictorGordan]

I don't have experience with trying to render so many triangles, my best advice would be to google optimizations. Maybe read a few scientific papers on the matter ;)

[@cjdaylight3407]

@@VictorGordan okkay thanks for fast reply

[@sunflower5244]

Why do most prefer OpenGL than D3D9? Are not both having same basic ideas to start with learn for beginners? Also most Windows softwares (browsers, games...) use D3Dx not opengl

[@VictorGordan]

I think most ppl prefer OpenGL because it has more tutorials and it's open source ;)
