Meet up with some local indie devs here in NZ. We have quite a big group here. The game meeting was over 250 people. There is also a indie dev space partially funded by the government. So that is cool.

As for what i did today, I have been trying to get 2 projects from my previous job off my plate.

Built a nifty little overview for my map editor, so if you're dealing with massive maps you'll be able to hop around between chunks pretty easily. You can also fill them with a specified ID, or blank them out. I also generated a 64km2 map, weighed in at 700mb and took about ten minutes. It's probably far larger than anyone would ever need from this engine but it's fun to see just how far I can push it.


Forgot to mention, I enhanced the window manager a bit just to add some more usability stuff.
Mainly, you can now do Ctrl+A, Ctrl+C, Ctrl+V, Ctrl+X, etc... in text boxes, and windows can now be minimized, and docked (which currently has to be specified programmatically).

I've had some luck recently with rendering Theora video in OpenGL Smiley I found some code written about a year ago using jheora's core classes (but not Cortado) and so far I can render videos to textures, but there are still some visual glitches and I need to play the decoded PCM.

Either wandering the forum or programming. Most likely the latter Smiley

Been playing with different OpenGL blend modes and generation algorithms to make my galaxies look more realistic (or at least, more like an attractive playground). It's improving but I still need to improve the distribution of stars: there's way too many at the galactic core and too few in the arms. Currently it renders 7500 stars and nebulae smoothly, which should be plenty. They just need to stop clumping together at the core...

Today was the deadline of my GameDev class in uni. We pretty much had months to develop a game. 3 days ago we (me + 2) started piecing together a multiplayer card game with Unity and we actually made it in time. Five months of university and i can still barely spell time management...

Turns out Unity is pretty great if you want fast results. The interface is also pretty nifty, and if you finally wrapped your head around how they chose to do things it's pretty fun to use.
That said, it did hurt my 'programmer's pride' a little to fill in text fields and drag around components. I think I'll stick to just code if I have the option to.

Also worked up the courage to put my amateur vocals on the internet for public listening. Wrote the lyrics myself. If you are a fan of piano, Attack on Titan, and.. amateur singing.. you might just like it.

Creative week!

Great job @Gjallar, sounds like fun to have GameDev classes!

I progressed a bit futher on galaxy generation today, here's a short video of generating galaxies with 2, 4 and 7 arms:

And this is one end-result, I'm especially pleased by the variety in star & nebula density:

It used to be the case that it could actually damage the hardware on nVidia cards, so... beware.

The whine is a well known thing on the 780 TIs, so hopefully that didn't hurt it. I put a frame cap on just in case though.

Just wrote the first 12 pages of my new book Smiley "The Definitive Guide to JOML - a pragmatic approach to learning 3D math."
Tried to use GitBook.com first, found its editor is slow as hell, buggy and typesetting and math just looked awefully awkward.
Fell back to my other Markdown friend StackEdit, but that looks horrible too. And exporting to anything did not work well.
Now for the first time after my master's thesis I came back to LaTeX with MikTex, and I really enjoy it.
It's a hundred times faster than any online solution to "compile" a PDF and regardless of the bad content Smiley I wrote until now, the typesetting just looks beautiful.
Maybe later I use some online book printing service to actually get me a nice paperback of it for just around €6. Smiley

EDIT:
Okay, just finished the next 6 pages in which I try to explain how to derive the general sin/cos formula for angular vector rotation in 2D Cartesian coordinates, so that people understand what the whole rotate/rotation methods in JOML do. Learnt a lot myself and had to find a way to actually explain that stuff, since I never found a good explanation of that myself. Even the excellent book "Real-Time Rendering", 3rd ed. just gives the formula straight away on page 57 and never says, why this actually works.

It's well written. I'm very interested in learning that maths properly.
When you explain these concepts to noobs like myself, it is often easier for us to grasp when you use actual numbers in an example to show where they are inserted into the formula and what the result should be.

By the way, I'm always dismayed that whenever someone smart like yourself sees improvements that could be made to existing texts, they always have to start again rather than edit the existing text, due to copyright restrictions or because the author didn't provide their source document or because it's in an incompatible format.

I learn most maths theory from wikipedia which is a great source but they don't have enough worked examples. Unfortunately, people who try to add worked examples to wikipedia usually have their additions deleted by the wiki stasi since wikipedia is supposed to be an encyclopedia, not a textbook.

LWJGL Util is deprecated and is not available since LWJGL3. Instead we highly recommend you to switch to JOML, which also gives you great performance.

I puked a little looking at their matrix4f class set up on github. I am now going to, since I only use Matrix4f and Vector4f from LWJGL Util, create my own classes.

KaiHH,
Could you check out my mat4 class later and tell me what is wrong with it?

So you plainly insult KaiHH's matrix class, then ask KaiHH for advice with your own matrix class?
Ok.

His works, but is very extensive. That should be expected, as it is for general purpose. 90% of the things in there I don't need and my methodologies are different. For example, he keeps floats, while I keep an array of floats.

You know better than to harass members like that, if you're pointing it out be upfront but friendly about it. This is what makes a community sour like TigSource.

But honestly we do need a new vectormath library, with a good following. It needs to be complete also, with 2D matrices and variable size + non-square support (In separate classes of course)! httpdigest has a good thing going with JOML so far and if you don't like it, don't compete make a branch of their repo Hydroque and make the changes needed! Every big change goes to a separate push of course.

Thanks for the feedback! I will definitely add more examples with actual real numbers.

they always have to start again rather than edit the existing text, due to copyright restrictions or because the author didn't provide their source document or because it's in an incompatible format.
I'm not entirely sure what you mean by that. When an author makes some big changes to some text I'd reckon it is because he/she thinks the new version will be easier to understand and the "read flow" and the "guiding thread" is just better.
Adding a single new paragraph in the middle of some other text usually disconnects the text before that new paragraph from the text that did follow it immediately. And if the paragraph was just added at the end (like when you add a new method to a Java class at its end), then with written text this paragraph should logically connect to the second-to-last paragraph, and not to some paragraph in between. If that is not the case, then the text needs to be restructured.
Text should not be something modular like a Java class Smiley but highly integrated and well-structured, where every paragraph logically follows on its predecessor, to keep the "read flow." Little changes to something can then lead to a complete restructuring of the whole text, yes.

I agree that nicely crafted paragraphs are good. But look at the success of wikipedia where each article is written by hundreds of different people who sometimes disagree. Wiki articles contain lots of sub-headings that can address quite separate ideas relating to the article's topic. An open-source textbook constructed in this way would be very useful for students who can consume it, teachers who can take the parts of it that they want, and expert contributors who could add so much more than a single author making an ordinary textbook whose copyrights are sold to the publisher, leaving the material to languish without updates.
The current textbook situation is laughable at uni where publishers release a new book every year with the same end-of-chapter question, but the question numbers are switched-around just to make the old versions of the textbook unusable for students who must complete the set question numbers for homework. This forces students to buy a new text for $150. Also, to prevent electronic copying many publishers still only make texts available in paper form rather than pdf or web page form so students carry kilos of useless paper in their backpacks.
Sorry for taking this off-topic from your excellent book chapters, but I think it's an interesting issue.

My previous job i was teaching at Universities in Switzerland, Austria, Germany and Czech republic. This represents a very wide range of wealth for the average student, and many can't really afford expensive textbooks.

Long story short it was always easier to use copyleft or free as in beer text books and resources for the class.

I also was one of the author of a textbook used in some classes. I get nothing, since its hard cover, sells for $100 or more and will never make the 5000 copy "profit" level for the publisher. Also it is a shit ton of work. Never again unless it is copyleft or equivalent.

However the uni's i worked at in the EU didn't have the English speaking uni scams of the professes textbook being the course book or his buddies. Some of my engineering books were over $200. I just went for old editions that where fine. They really didn't change anything. 

As for what i did today. My brother finished a logo and we should have business cards this week. Also i wrote more skinning code this week with a few IK tests that showed how much isn't working.
