3D island in Love2d: fog thoughts?

[Madrayken]

Hi folks,

I'm planning on making my next game in a weird 3D view using large numbers of billboards. Imagine the rotating island in Yoshi's island and you're close - just 100% side-on. I've got plenty of experience and I think I can bend Love2d to my will.

The only thing I'm not sure about is how best to implement the depth-fog in the shader.

The shader will look at how far the object is from the camera and blend to a standard gradient I'll be using for the sky.

Fog changes with distance from the camera. This 'z' component will be my own creation (i.e. not something the shader knows about), and something I'll have to pass in to the shader somehow. However, I don't ideally want to have to pass in a different Z with every object as that might well create a rather horrific performance hit. Does anyone have any suggestions on how I can feed a shader this information in a slightly friendlier way?

Shaders aren't my strong suit. Spellrazor is an exception - everything I did there was kind of easy.

Edit: Never mind. I've added a love file here: http://www.mediafire.com/download/91rr5 ... sland.love
I'm an idiot. If I'm using buckets to sort, as I do here, I can use the drawing of those bucket-levels as opportunities to change colour, which is already sent to the shader and can be interpreted however I want. It's not super-fast, but it might do.

I think you can use LÖVE3D for that

Trying to stick to fake 3d for weird reasons... :-)

Oh dear, this just freezes and looks like this:

I'm on a laptop with an intel i5, so I guess you'd want to optimize...

It looks like it's frozen but have you tried the arrow keys?

Oh snap, you're right.
It moves and it moves smoothly, my bad.
I guess my hardware/driver doesn't support the shader you use. What a pity.

It looks lovely, but I could only run it with my discrete graphics card, so you might want to dumb it down for less advanced ones.

Hmm. I use lots of weird shaders in my work. Is that frequently an issue with users here?

Just tried it on my Windows gaming rig, still doesn't work. Very strange.

Um... The build I downloaded has no shaders at all, is that intended?
