I'm really looking for a matrix transform I can do on 2D coordinates to move them from a Cartesian plane to a Gall-Peters style projection, however I would do that. Thanks for the reply though!
This is not possible using a common transformation matrix.
The problem is that matrices (for which the matrix-vector multiplication is defined as 4 dot products) can only represent 'linear' (i.e. "affine") transformations and perspective/orthogonal projections.
And 'linear' meaning that, in order to produce the output vector from an input vector, you can only apply simple '+' and '*' operators that only directly take the vector components as operands.
Now, the formula for Gall-Peters projection has a non-linear component between input and output, namely the sine.
But, there you have the transformation formula and can apply this to your coordinates.

Hi there!

I'm one of the five guys making up Crimson Owl Studios and I just wanted to show off of our first game (currently in Early Access): Caromble!
From Monday till Thursday we live ordinary lives as software developers at respectable companies but on Fridays we are Crimson Owl Studios - an independent one-day-a-week game studio from Utrecht, the Netherlands - developing Caromble! from our kitchen tables.

Check out our game trailer:

Also check out our Steam Early Access explanation video:
https://www.youtube.com/watch?v=wSm2pXs8LZU

Caromble! is written in our own Java-based game engine. It relies on JBullet and a heavily modified version of Ardor3D.

If you have any questions, don’t hesitate to ask!

Your Dropbox images are not public - you are the only one who can see them.

Your domainname redirects to http://73.9.75.150:8886/index.html, which is accepting connections but timing out.

I'd treat the top and bottom row of the 2D grid as the north and south pole. The left and right sides connect together. If you need to cross through the poles, i.e Move past the top row to the bottom row, then instead of shifting the object vertically, you'd instead shift horizontally by (width / 2), and start moving in the opposite direction.

I'm trying to accomplish something like this,
<a href="http://www.youtube.com/v/bi4b45tMEPE?version=3&amp;hl=en_US&amp;start=" target="_blank">http://www.youtube.com/v/bi4b45tMEPE?version=3&amp;hl=en_US&amp;start=</a>

See how when the continents move, and the points of color at the bottom are moved to the top simultaneously.



The top-most coordinate system is what I am looking for. But for example, if I had a grid of objects like so,
1  
Object[][] 2DUniverse;

How would I make the bottom most universe react like the one above? Using out of bounds checks?

I may be having a brain-fart. Can someone please help me?
Thanks in advance.

What do you mean by "better"? OpenGL Compute != OpenCL
OpenGL compute shaders have better driver support is what he's saying.

Screenshots look cool, I've just cloned it  Smiley. Any suggestions for building it for desktop?

Not adword - but i want share it:
https://www.kickstarter.com/projects/snair/o-watch-a-3d-printable-smartwatch-kit-for-kids?ref=category_featured
https://www.youtube.com/watch?v=VscJiLO11h4
https://www.youtube.com/watch?v=XOLOLrUBRBY

i feels old Wink

p.s I want share it: because after i watched it - I remembered something very important that I forgot with time.
Things are not so complicated as we think about them now
Think simpler.

Simple example when I making first games – it was so simple code
All gui in code like inventory.setPos(150,30) – and it was fun to write this, test it and play.
Now I have so many advance libs: export/import external format, Gui manager etc..
I can do more work in 2-5 times with them then previous,
But for some reasons it no so fun as before, even painfull some times (many understand me)
The irony I have more advance system to do more work in less time but I spend less time to work,
Because this complication that makes all process heavier (in head).

And remembered that before it was so simple and now it still the same)
return me fun and inspiration to make more =)
Its not about throw away all libs – its about don’t think hard)
(and not only programming ^^)

Up: also - more offtop)
Also – internet full of free educational courses

personally i watch fully http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/
and hope find some time for others.
we have many internet tutorials how to - but you may know basics, or its be very hard to understand and copy-past solution – so university lectures and official tutorials give such basics
(java I learned from Oracle tutorials and http://math.hws.edu/javanotes/contents-with-subsections.html thanks to Hobart and William Smith College)

Why Mit videos and not Edx
For me not important certificate (I do it because am interesting)
but important to watch video ride on time - when I have such time, not waiting week or two for new part Smiley
(or I not see such option on EDX)

It be good to go university and learn all there – But it not end of you’re world if you can’t go there for some reason,
If you want learn something: you have internet – use it, search and you find what you looking for)

IMHO: I like EDX idea – but it looks so old technically for me and hard to fast use:
I want full list of video on some theme available in any time,
(why videos lectures – it be betters Text like programming tutorials + gif like in Wiki or even interactive javascript ^^)
with tasks to solve and hints for solving most common mistakes + end solution of task.
And ability to download all this to solve it offline)

IMHO ^ 2: And yes I don’t have graduate Wink
When I try go to university – they say I stupid to go free education
even not pass me to second mandatory exam,
But call me after 2 weeks that I can go to Uni on contract (payed) XD
(even without second mandatory exam which is mandatory for contract too ^^)
In any case I don’t have money for it Wink, same passion to trying in another Uni in my country
Simple see how education is useless for ppl in my country and don’t what spend 3-5 years for nothing (see many bad example in own life: one of which I have “A-” for chemistry in school but for 5 years teaching it I never hold in hands test-tube ^^, we simple don’t have any practical experiments XD)

But now there are free online tutorials and I can not even express how much I am grateful for them.

Many successful ppl don’t have Full graduate – so don’t give so small circumstance like lack of education stop you.
p.s This all my personal opinion – and it may be not so good for you,
but in any case you have ability to learn something for free if you have internet connection)
