[Programming] Halp with Lumin brightness.

[Oddity]

I need to mod the client's Lumin object, but the whole rendering thing is too complicated for me to understand without diving into it deeper.

Currently, this is how bright a single object with a Lumin is (in pitch darkness):



On the right side of the picture, you can see how bright a second Lumin overlayed over the first one is.

I want a single Lumin to look more like maximum daylight brightness:



Currently, stacking a whole bunch of Lumins on top of each other just gives me this:


Been playing around with ILM.java for a while, but haven't managed to get the effect I want yet.

If I get bit of breeding room from uni I'll give it a go. Hope it wont be to late by then.

I can get the desired shape by changing the ILM.java static block to this:

Code: Select all

static {
   int sz = 400;
   BufferedImage lb = new BufferedImage(sz, sz, BufferedImage.TYPE_INT_ARGB);
   Graphics g = lb.createGraphics();
        Color c = new Color(255, 255, 255, 128);
        g.setColor(c);
        g.fillOval(0, 0, sz, sz);
   ljusboll = lb;
    }

But playing with the color values hasn't helped me change the amount of brightness per Lumin mask.


The maximum brightness I can attain with repeated Lumins is also rather low still:

You adjust the ambient color of ILM

Here is your solution m8. Just reverse color or blending and you should be fine. Dark outside and bright inside

Dark outside and bright inside

Yeah, got that part figured out. But I can't get it to be as bright inside the circle as maximum daylight (eg. if you have nightvision enabled). Even if I overlay 1000 of them on top of each other, it still won't be very bright (and I'd like to just have a single Lumin object be that bright — perhaps with adjustable strength as the Lumin object would lead you to think is possible).

You mean this line?

Code: Select all

amb = new Color(0, 0, 0, 0);

Thoroughly playing around with its values didn't have any effect.

That's because amb is set to the glob.amblight everytime MapView is drawn which changes based on what you send to the client through the server.

but as Nummy said you basically have to get the blending right so that the dark areas stay dark but the areas that should be lit up are brighter (aka: more transparent so that it doesn't block out the tiles/objs drawn below it)

I'm not even sure where to start. I might have to learn a bunch of OpenGL and study loftarb's rendering pipeline unless somebody can help me out.
