Share My Creation Cells - Animation

when 2 cells collide in the middle they will unite. as bigger the cell as slower it will move.
animation end when all cells are united

Hey Ilan!

It looks really cool but I can't really understand what's going on.
Are you simulating some kind of physical process or is it just digital art?

The framerate on my PC is really low... 8 FPS at best... Is it supposed to be this way?

The framerate on my PC is really low... 8 FPS at best... Is it supposed to be this way?

the reason for the low FPS is i create an array of all pixels in the screen (600*400=240.000)

and go through them in a loop do draw each pixel as needed (to get that effect) since it is a too large array i had to do it in step 4
so my array is now 15.000 big) and every frame i need to go over all pixels. this is not easy. on my pc i get around 25 FPS
i could make the step to 8 and like this increase the FPS and also get a nice Pixel Art Style.

it is just a nice animation not more then that.

It would be really cool to have it running 60 FPS... If only we had OpenGL in B4J...

 

[wonder]

Alright, compiled from source it runs super smoothly at 60 FPS, while the downloadable Jar barely achieves 8 FPS.

- What version is you B4J?
- What version is you JDK?
- Is you JDK 32 or 64 bit?

b4j is 4.01

JDK is
32 or 64

where do i check it?

EDIT: jdk = jdk1.8.0_65 (i am updating now the jdk to see if i get better performance)

 

[wonder]

Is it on Program Files or Program Files (x86)?

 

[ilan]

i have updated the jdk and b4j but performance has not increased much.

change the scale to 1 and you will see what i mean (scale 1 = full array (600*400 [240.000 pixels])

 

[ilan]

maybe opengl would be really a nice addition for b4j

@wonder you can also play around with the colors

for ecample:

For Each p As pixel In pixels
        Dim sum As Int = 0
        For Each cl As cell In celllist      
            Dim d As Int = distance(p.x,p.y,cl.x,cl.y)
            sum = sum + (500 * (cl.r/d))
            sum = Min(sum, 255)
        Next  
        p.color = fx.Colors.To32Bit(fx.Colors.RGB(sum,128,0)) 'HSLtoRGB(sum*5,sum*10,sum*0.8) '
  '...

Yeaaaaaah.... Just imagine, making games in B4J (LibGDX style) and uploading them to Steam. Big money!!!

By the way, have a look at the difference:

 

[ilan]

on my pc i get the same result for the jar file as when you build the project. dont know why the jar file runs so slow on your pc. on mine it runs fast

 

[wonder]

Is it on Program Files or Program Files (x86)?

You didn't answer me... Where is you JDK folder? I'm really curious to know the difference between our Jar files...

 

[ilan]

you know what could be archived from this source? a nice blood animation where small blood particles falls into a dungeon. and with a little physic (magic) the animation could be very nice

 

[ilan]

You didn't answer me... Where is you JDK folder? I'm really curious to know the difference between our Jar files...

C:\Program Files\Java\jdk1.8.0_101\bin\javac.exe

 

[wonder]

So it's 64 bit... same here... hummmm... maybe @Erel will shed some light on this mystery...

 

[ilan]

So it's 64 bit... same here... hummmm... maybe @Erel will shed some light on this mystery...

yes its 64bit

 

[ilan]

i have uploaded a new jar that was build with the latest b4j and jdk, tell me if you get the same result

 

[wonder]

Still slow... did you compile on release mode?

 

[ilan]

Yes and here the jar runs fine.
