These presentations are actually really good (Maybe you could stylize them according to your video/channel color palette)

[PenguinMaths]

Love the powerpoint! As some others have pointed out, I'm confused why layering a semi transparent color over a fully opaque color would yield a semi transparent color, as shown in the alpha channel of the last slide. Great series.

[rynho]

Damn those slides are so good man. Keep them up, they really help us understand better than just showing pieces of code.

[ucmRich]

The "way" you designed your ppt presentation to coincide with how you teach is brilliantly on target. My brain gets it! thank you!
** also thank you for everyone helping to support him!

This is your most professional presentation/tutorial. Having a written power point presentation greatly improves your presentation style, keeps you focused on top in the correct sequence, and helps eliminate the unnecessary meanderings and ramblings. I strongly recommend you create a PPT presentation as a reference to your future tutorial videos. Keep up the great work!

[raadyrenesbane]

That was a nice and concise presentation. It’s a good initiative and makes it clearer. Plus you can pause the video to think. A presentation + live coding is what most teachers do at university.

Wow, about half a decade ago I learned Java from your videos. Now I am doing it professionally and when I search for an opengl problem
I stumble across this. Huge nostalgia wave crushing over me.

[Gettingitfiguredout]

Thought the power point was really helpful, thank you for taking the time.

I love this quote : It is really quite simple once you understand how it works.

10:55 Does this mean that the overlap of the white square with the magenta rectangle has an alpha of 0.75? Seems weird how the opaque rectangle with the semi-opaque square creates a semi-opaque result. Or am I interpreting this wrong?

[polaris]

I've been reading various guides online about this for the last couple days, I shoulda just watched this 12 minute video because you explained it better than any of them. Thanks for posting this, it really helps that you explained *conceptually* what is happening.

[aura-audio]

Loved the powerpoint presentations! I understand this concept very well now!

[alexandrosmoysi]

Presentation is definetly a great tool for you, it lets you take your great explaining skills for code, and use them on non coding topics. Best course ever!

[ibrahimrashwan]

Totally in with the that new style of using presentations simple & strait to the point and it's easy to understand

[koungmeng]

8:14 why do we need to calculate alpha value if we dont need that? we need only the RGB values to determine the color, the alpha value is meaningless to us because we use it to find the RGB.

[victorlucki]

The slides were a really good addition! They help visualize all the theory quite a bit.

Please, so continue with them, if it's not too much work, of course.

[clem]

In the last example: something semi-transparent (a=0.5) on top af something opaque (a=1) gives you something a bit transparent (a=0.75) ?

[vectork]

Thanks Cherno! I really like this new presentation style. Its really easy to understand. Love from Nepal :D

[michaldvorak]

Really a fan of this presentations style of teaching, would definitely be delighted to see it in your future videos!

[ty_teynium]

This is similar to the siggraph class lecture presentations, but from your own home, I did actually pick up a lot of what you were explaining this way, but it can be a lot of work that’s why I just wait for the code parts so that I can see what works and where to put them.
