After (only ) two weeks, I have managed to write an article to my latest tutorial about uniform buffer objects! Check it out:024.) Uniform Buffer Object
This one is pretty long, but don't get discouraged! It's a very good knowledge useful for your 3D graphics career .
One more month has passed and I bring you a very cool tutorial this time! It's about Uniform Buffer Objects . They exist to help us re-use uniform data among several shader programs, so that we have to set them only once and then use when needed. The tutorial can be found here:024.) Uniform Buffer Object
I hope you'll enjoy it and also learn something new . You can add new point lights with Space key and reset them with 'R' key .
Article is not yet done, but I suppose I should write it until the end of this month .
As I had a free day this week, I have finally decided to review and finalize CMake support of my OpenGL4 tutorials. If you pull now the latest changes, the tutorials can now be built using CMake both on Windows and Unix based systems!
I'm not 100% happy with the CMake solution, especially for Windows, but for now it's at least something and most importantly it works, so it's better than nothing . I might still upgrade the CMake build in the future, but at least I wanted to have all tutorials covered.
I have also successfully built the tutorials on my Linux Ubuntu 18.04 virtual machine. I couldn't run them however, but it's because virtual Linux doesn't support OpenGL 4.4 Context. I need to find a machine with Linux natively to try it out. But I guess if they compile without any issues, I really hope they will run too . The documentation and how-tos can be found in my repository.
So after 3 weeks, I have written the article to my 23rd OpenGL4 tutorial about point lights, you can read it here:
I'm sorry that it took me ~2 months to bring another tutorial, but it's finally out! It's about point lights and you can find here:
It took me a bit longer because I had lots of activities almost every weekend (because it was holiday) and so I did not have many free weekends. Even if I did, I was glad to just be at home and to rest .
As usual, article will be added later .
Three weeks later, I have added article to the 22nd article of my OpenGL4 series about cylinder and sphere . Check it out below:
Next tutorial I have already decided to be about point lights, other topics that will come sooner or later are particle systems, metaballs, keyframe / skeletal animation and much more .
One more month has passed and I bring you another tutorial. This time it's about generating meshes for further two primitives - cylinder and sphere! You can find the tutorial here:
I've put a lot of effort into this one, as I've created a simple solar system in this one . You can play around a lot in this one and you can control many things, see for yourself . I got inspired to do something like this by SpaceX first human flight mission, that took place exactly yesterday (at the time of writing this news), so that's why I created a bit more unusual scenery and environment .
As usual, article will be added later, because writing an article is sometimes even more difficult than writing the code itself .
Finally I have finished writing the article for specular highlight calculation! I have re-used ancient texts from OpenGL3 tutorial series and refined them a bit . Have a look here:
Next tutorial is already in progress and will teach you, how can we render cylinder and sphere .
After two and half months, I am bringing you another tutorial, this one is about specular highlight! Check it out here:
It took me a bit longer than usual, but I was really overwhelmed last months. Anyway I hope you will enjoy it . I will add article a bit later.
Because of the corona virus outbreak, the company I work for has decided to do a two-week complete shutdown as a prevention measure. For me that means I will work on tutorials basically full time now for two weeks, so I plan to finish the support for CMake completely, add support for VS2019 and some minor refactor of older tutorials. I will keep you updated!
Article to the fog tutorial is online, check it out here:
Took me just a week longer than my estimation (last weekend), but it's quicker than last time! Hey, and also stay tuned for the new tutorial, this time I won't say any timeframe, but soonish .
So as I promised, I'm delivering another tutorial this weekend. Well, it's already after weekend , but in Slovakia, we do have a prolonged weekend as today is a national holiday, so it still counts, right ?
This one is about how to implement fog. I've just re-used scene from the last time, but added a snowy skybox as it's currently winter . You can find it here:
As usual, I will write article a bit later, hopefully next weekend .
Dear readers of my webpage,
I just wanted to tell you that you're awesome and wanted to wish you all the best in the new year 2020 !
As regards tutorials, I have almost finished my 20th tutorial and will upload it on the coming weekend, so check again on Sunday or so .
I have finished writing an article for my latest tutorial, you can find at tutorial's page:
I hope you will enjoy it! I've already started working on next tutorial, topic of which I won't reveal yet .
Hello guys! . So after 6 long weeks, I come with another tutorial! And finally I have implemented reading models using Assimp library. Check it out here:
It took me a while to finish it, but the problem was adding Assimp to all of this was a bit more difficult then I have expected. At the moment, I haven't done CMake version yet, only this VS2017 version and it seems to work, I'm just not very happy with the way I have solved it, but at least it works (on my machine at least ). One simply has to download prerequisities after cloning repository by launching the added script download_prerequisities.bat (it updates submodules and also downloads pre-built Assimp libraries, as they're quite huge to reside in repository). Soon I will also add CMake version and maybe later I will make a better solution for this VS2017.
Anyway I didn't want to prolong this forever, so enjoy the current version for now at least .
Hello guys! It's been a while since any update and it's because I've been super busy in the summer - there was just lots of events happening that I have attended lately (family visits and 3 weddings) and every weekend I've been travelling to somewhere else, so I wasn't stabilized in order to write an article. But finally, I did it during this weekend and you can find it here :
As mentioned before, my next tutorial will finally be about loading 3D models from files, so stay tuned!
Another week went by and again I bring something new! This time, it's the last tutorial about heightmaps for a while and it teaches you how to use multiple layers within a heightmap and how to transition smoothly between them! Check it out here:
The article will be written a bit later as usual . My next tutorial will finally be about loading 3D models from files, so stay tuned! I hope I finish article next weekend and then within two weeks new tutorial .
All the best for the upcoming week fellow readers !
Finally I've finished CMake support for my tutorials, but only on Windows for now. It took me a while, as I had several problems with FreeType especially, but after lots of googling and trying, I just made it my way for now and it works in the end, so that's cool .
Linux support is going to be added soon. I know that on Linux things work much more different than on Windows, but from my work I know how to use CMake on Linux properly, I just need some more time for that and a native Linux computer, where I can test the compiled code, if it works properly.
18th tutorial is on its way and will come next weekend !
As promised, I'm bringing you yet another article to my latest tutorial! Check it out right here!017.) Heightmap Pt.2 - From Image and Skybox
I wanted to finish it during the weekend, but it's just so hot in Slovakia (and everywhere), that it's really difficult to sit by computer . But finally I've done it, so I hope it will serve you well .
After 3 weeks, I come with a new tutorial! This time, it's about extending skybox class with loading a terrain from image and surrounding our scene with a skybox! Check it out here in this link:017.) Heightmap Pt.2 - From Image and Skybox
As usually, I will come with article a bit later, I suppose next weekend . Besides, I have started to work on CMake support for my tutorials! It's done to some extent in a separate branch called cmake-support, in case you would be interested. I should finish it in relatively close time, just had some problem with FreeType.
I wish you a nice and successful week !
Took me a while, but I've finally written the article for the Heightmap tutorial! Check it out right here:
It took me a while to write it, but the reason is, that I've been on a vacation with my wife in Dominican Republic for 2 weeks and during that time, I was not working of course . But now the article is there for you to read, I hope you'll enjoy .
