Awesomium uses ARGB instead of RGBA color. When you get the renderbuffer, you can specify it to swap order.

awe_renderbuffer_copy_to(pRender, pBuffer, width * 4, 4, true, false);

I know that, but like I said it would be difficult to fix without having a noticeable performance hit. I'll dig into Slick2D and figure something out.

I have two applications submitted so far, and a third will be done by the time the deadline comes around.
A compass (probably wont get through)
A syncing e-reader (more likely)
and TBA

i have to resubmit mine, apparently i fucked up the signing process and didn't sign with RIM's key, only my own

Oh well.

Wow, how did you do that? I thought SD cards were basically unbreakable. (They don't have the weakness of having a separate connector like USB drives do)

Well, first of all, if you're going to do bloom, you shouldn't just downsample and linearly interpolate.
What you need to do is downsample to a few different resolutions, then apply a separable Gaussian blur, then combine the results. The Gaussian blur is the important part. The downsampling is done for two reasons:
1. It greatly reduces the number of fragments you need to filter.
2. It allows you to exploit spatial locality when you need to sample over a larger area. (much better cache hit/miss ratio, huge performance impact)
For you to benefit from the downsampling step, you must ensure that your blur is not writing out to a full-resolution buffer. It is the resolution of the target that determines how many fragments are processed, not the source. The downsampling/mipmapping is worthless if you are filtering at full-screen resolution anyway.

Second, you're only giving us a small fraction of the information we'd need to figure out what's going on. We can't help without having the whole picture.

Thanks for the tips, I finally got it working by changing the downsampling size from 512.0f to (render_w * 0.25f) and it worked like a charm.... probably a ratio related problem. I'm applying a gaussian convolution pass only once giving me the result below:



Now is using different resolution for the bloom pass really necessary? I mean one pass is already pretty close to the real deal.

I'm trying to learn how to create associations between objects in OOP. Say I have this diagram:



Basically, any Workplace may have any number of Employees but an Employee may not work at more than one Workplace at the same time.

What is the correct way to implement this in an object-oriented programming language?
My guess is that the Workplace class should manage an array (or possibly a dynamic list) of Employee instances and expose methods to add or remove employees, which would naturally map them to said array.

An Employee object, on its side, would have to be added to a Workplace object.

Now that I think of it, though, there's a problem with the fact that the relationship from Employee to Workplace is not enforced in that multiple Workplaces could have the same instance of Employee added to them. How could I avoid that situation? Is my whole idea correct?

It's basically correct, yeah. Maybe your Employee should have a pointer back to its parent Workplace, and when Workplace adds an Employee, it has to ask the Employee whether its parent pointer is null. Or maybe that's a horrible idea.

EDIT:

Well, disregarding the fact that you're a self-professed "HUGE idiot", I can't imagine a situation in which a force could be applied to a thin card that would snap it. Well, maybe if you roll over it with a chair wheel and the pressure in the middle is too much, but I would think that since it's flat, that wouldn't affect it. Although I have broken CDs that way.

I'm talking about long and thin ones, like the ones sony devices use.

These could certainly snap in half.

A set can enforce the no duplicate employees. Thats not really an OO design issue, but an implementation issue.

I think they usually apply a gaussian blur during each upsampling pass to hide the bilinear upsampling artifacts. Instead of upsampling the whole thing all at once using bilinear, they blur, upsample, blur, upsample, blur.
It's sort of a refinement you can make. There's no need for it if you're happy with the results you've got now.

I've started implementing a tile engine. I'm beginning to regret using the tiled map format now.. it's shit. I'm working off some parser someone wrote for SFML 1 (I'm using 2) and I keep running into brick walls with it. I've managed to get it to work kinda but I'm getting this:

Anyone have any idea what this might be caused by? I have one big tile map image in memory and I'm setting the sprites to subrects of it :/

Edit:

Nvm, fucking sfml and its obscure technicalities.

Is it bad that I'm trying to make a Space Station 13 clone when I've never actually played it? (Doesn't work on Linux, runs like shit on Windows.)
I just really like the idea.

I would love some input and advice on it, hell I'd love it if someone worked on it with me. Would you be so kind?

I'm having a little issue with HDR,. This is the wanted result, only works if I render it directly to a screen quad



However if I bind the output to a buffer I get a weird artifact... (I tried to change the buffer to GL_RGBA16F and to clamp/unclamp it but no luck) not sure what's causing it, anyone seen that before?

Ew, box blur. You should use gaussian weighting for it instead. And the tearing is probably caused by the quad you're drawing it to (the diagonal slice happened to me before with XNA, it's a bug with the texcoords of the quad I was drawing to...) The rest is probably also caused by the same thing.

Grid-based movement for starters.
Needs a semi-realistic atmosphere system, to allow all sorts of hijinks.
Basically, go ask the people in the SS13 thread here what elements are needed for a game like that.

I've spent the last week or so trying to figure out how one could implement a Levenshtein Distance spin-off that used the physical location of the keys on the keyboard to determine the difference, instead of the insert/replace/delete operations that his uses. The advantage of this is that it takes slip-ups or accidental keypresses(or misses) into account.


And it seems I've succeeded!

The military is not so bad as long as you realise its a system.. And like any computer system there are rules you can manipulate, quite a good programmer environment. Just make sure you end up in an officers environment, being a grunt isn't quite the same.

Trying to rig up an inventory that'd work well for the iOS and Android versions of my MMO.. The series of boxes is a GuiControlSlidebox, using my awe-inspiring GUI system, so you can slide it up and down to reveal 16 panels total.

If you click on one, it gets highlighted, if you click it again after highlight, a dialog comes up that'll say shit like equip, drop, info, or whatever.

So I have been having a problem with this, I have an object in 3d space and I need it to look at the mouse, no problem.
The only problem I have right now, is that the object only has the right rotation when the camera is on the same height, when I move the camera around it doesn't work right anymore.
Does anyone have an idea how I can write some code to compensate for the position of the camera?

This is the code I am using now. It uses a raycast from the camera to see where the mouse is in world space.

ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit, 1000f))
{
     radians = Mathf.Atan2(hit.point.x,hit.point.y);
     degrees = Mathf.Round((radians * / Mathf.PI));
     object.localEulerRotation = degrees;
}

Oh my, looking at the unit details for the unit I mentioned earlier, it turns out that the introductory session is not only in C, but is also in Linux. I am impressed considering this is only an introductory unit common to all engineering students.
