OpenGL Tutorial 30 - Bloom

[@gokhancakr661]

i watched all the playlist . thank you for your time. it was very informative

[@diahaidificbs]

Exactly what I was looking for, I remember TES Oblivion used to abuse the fuck out of bloom effects back in the days😂 awesome tuts Victor.

[@VictorGordan]

Thx :) Yeah, some games really went over the top with bloom

[@VictorGordan]

Just a heads up to everyone! This method isn't great at all if u want your bloom to cover a large area. For a better method watch the Cherno's bloom video ;)

[@perefm]

It would be good if you could make a video explaining the implementation Bloom for large areas... I have seen the explanation from Cherno's video, but still I think that are few questions to answer about how implementing it... imho :)

[@kylehagy9762]

I have been trying to learn opengl for years and you have the best videos I have ever seen. Thank you!

[@VictorGordan]

Good to hear you finally cracked into it :)

Thx :)

[@mitchellkelly241]

Victor is back! :D Thanks bunches my friend!

[@SB-rf2ye]

probably one of the best opengl channels :)

[@VictorGordan]

Thx! :)

[@thezild3156]

amazing tutorial your channel is like opengl made easy

[@VictorGordan]

Thank you! :)

[@andraskmeczo575]

Very good video my guy! And although this blur is very good for beginners to grasp the idea, this effect isn't really bloom. To achieve really good bloom, you have to create a series of continuesly smaller textures like 1920x1080,960x540,480x270, etc and blur them using the texture before, and then add them again using the smallest and the second smallest texture, then add the result to the third smallest texture, etc. TheCherno's video called "Bloom." gives a really good overview of the effect, and how it works in Unity, although he doesn't actually show any code. Again, your example is very beginner friendly, and that is appreciated, but this effect can be greatly improved

[@VictorGordan]

Yeah, the pinned comment of this video warns that this isn't the greatest bloom out there and recommends the Cherno's bloom video ;)

[@andraskmeczo575]

@@VictorGordan oh I'm basically blind then. Sorry about that. Keep up the good work tho! You are a gem to all of the beginners out there who need some advice other then the learnopengl website

[@TheFreelegovideos]

Another great video, thank you very much! Do you think it is in the future for your channel to do a tutorial on a raytracing or ray marching hybrid algorithm for OpenGL? I've seen that you've done some other PBR techniques as well, so that would be super cool to see too

[@VictorGordan]

I haven't really done any PBR yet. But yes, at some point in the future I will look at ray tracing :) Also, thx ^-^

[@octopro8937]

Hey victor. I kno this is a whole year late but when I was on tutorial 17, when I load the grass in the grass has a black outline. I compiled your code and it does the same thing, however the video doesn't have the outline. Can you please help

[@VictorGordan]

Hmmm, maybe you are not enabling alpha blending? Otherwise I have no idea what the problem could be

[@octopro8937]

@@VictorGordanSir what do you mean by alpha blending?

[@octopro8937]

if you mean the threshold alpha thingy I copied and pasted shaders to make sure they were right. Idk tho maybe I'm stupid

[@VictorGordan]

Watch my tutorial on blending, or read this learnopengl.com/Advanced-OpenGL/Blending

[@hvroblox]

Underrated channel

[@silvertakana3932]

Hey victor, is this the last tutorial on this series? I have some more ideas for this. Why don’t you make a tutorial about screen space reflection or maybe even fancier screen space global illumination?

[@VictorGordan]

Yeah, it's the last tutorial. I'll still make computer graphics tutorials but they will be more generalized, so not necessarily for OpenGL, and mostly just an explanation and pseudo-code. For an example of that you can watch my PBR video ;)

[@landoz1]

how can i implement the frame buffer from this so it works with the skybox? right now everything turns black if i add the skybox code

[@PhamAnhKhoa118]

It has been 2 weeks since your last video. I hope to see your next video soon!

[@VictorGordan]

It should hopefully be out in 1 to 2 weeks 😬

[@MultiGreen213]

Awesome video! I'm wondering if it wouldn't be too much of a bother, could you make a video where you give a concrete example of how collision detection works in 3D space?

[@VictorGordan]

I plan on making a whole series on game Physics, so yes :)

[@blxxdbvrn]

As someone who wants to make an engine that looks like it's got 2009 graphics, I'm offended. 3:39 Jokes aside man this tutorial helps haha

[@shinystick241]

Awesome, What's next?

[@VictorGordan]

Deferred rendering

[@shoqapik3D]

Hello, is that possible to make a tutorial to add collisions or / and physics ? I'm trying to code a 3d game using OpenGL. Thanks you for your tutorial

[@VictorGordan]

I might do that in the far future, but not anytime soon :(

[@shoqapik3D]

@@VictorGordan Yeah I think it's hard. Thank you for reply. My game idea is very difficult and I didn't find any tutorial about some idea that I want to add in my game. But thank you for your awesome tutorials.

[@immortaldev1489]

Hi, I've downloaded the code and ran it, but only the top right of the texture has bloom, with it fading out, is there any reason for this?

[@VictorGordan]

Hmmm, not sure tbh

[@akriminsoe5527]

I am waiting for next tutorial.

[@Korazza]

How can we make it work after a window resize in full sized window?

[@VictorGordan]

Not 100% sure what you mean, but you need to make sure your glViewport() also gets resized as far as I know

[@Korazza]

@@VictorGordan ok thank you, I'll take a look at how to listen to window size changes

[@shinystick241]

it's been two weeks, when is the next video?

[@VictorGordan]

One or two more weeks

[@Max29847]

Can you do a video on a basic particle system please

[@VictorGordan]

I will at some point :) For now you can watch my instancing video. That gets pretty close to a particle system

[@aousmohammad2045]

Hello sir, can you talk about collision ?

[@VictorGordan]

I will have a series on Game Physics, but I'm not sure when I'll start it. Maybe sometime next year

[@akriminsoe5527]

pls upload about Perlin noise, terrain generation and tessellation. This is really important to make a game, right?

[@VictorGordan]

Depends on the type of game you make. But don't worry, I'll cover all those topics

[@akriminsoe5527]

ok thanks, I am waiting

[@pang3351]

Can you make game from OpenGL? Like a workshop.

[@VictorGordan]

A lot of people ask me this. I might, but it's not on my priority list :)

@@VictorGordan Ok cool, take your time.

[@navossoc]

Great videos! I need to go back and thumb's up all them now... Let's say I have a box and I want to create a simples/small fog/flare/bright/chrome/sparkles (something like that) around the box (that follows it), how I would implement that? Should I create the effect on the fragment shader? I'm really lost on how to do that...

[@VictorGordan]

Hmmm, I suggest rewatching the Shaders tutorial or reading up some more on shaders. The vertex shader deals with vertices, not the effects you mentioned. Those would be done in the fragment shader. Most of the things you mentioned are quite different from one another in their implementation, so not sure what to tell u lol. Just google each of them individually and you're bound to find something

[@navossoc]

​@@VictorGordan Yeah, after I wrote it I saw that I made a mistake, it's fragment shader. I edited it later... No problem, but shaders are the right way to go to make this kind of effects? I'll do more research knowing now what to look at.

[@andraskmeczo575]

@@navossoc about the flare, ThinMatrix had a video about this in his OpenGL 3D Game Tutorial series which ran like 5 years ago, although he used this effect on the Sun, you could achieve the same. He also has a fog video if you're interested, in part 14/15, something like that

[@silvertakana3932]

Victor, when bright objects get too bright, whatever colour it has will all become white. But for this implementation, it will still have the same colour. This video explains it in more detail. kzbin.info/www/bejne/qnqaYWB-fshoqNE

Yeah, the video by Cherno is really good, I think he uploaded it a few hours before mine or a day or smth like that haha

[@silvertakana3932]

@@VictorGordan are you going to make a follow up tutorial fixing it?

[@VictorGordan]

No, since it's not necessarily wrong, just not optimal. But I might do another video on the topic in the future

hey Victor Gordon stop upload tutorials about opengl and start learn bullet physics ,now!!!. You never be a game developer without physics.
