Plasma effect with copper

geldo79 · 03 November 2021, 23:16

Hi,

I just tried to implement a plasma like effect using the copper with horizontal and vertical waits. In general, it works. In the copperlist, i wait for every line and change the background colour at every 8 pixels. In a routine, i update the colors using precalculated frames. This generates a nice effect, but as the routine has to update 40x212 colors (320 pixels = 40x8 pixels, and 212 lines ), the routine is rather slow.

In principle, my routine can update the screen using frames with a resolution of 40x212 pixels (each color block 8x1 pixels). But i wanted the size of the precalculated frames to be small, and as i also wanted cubic color blocks rather than 8x1 pixel blocks, my frames have size of 40x27 color blocks (each block 8x8 pixel). But to produce the same line 8 times, i would also have to do the horizontal waits in all these lines ( like if i used the 8x1 blocks). Thus, i save memory, but not calculation time.

In some demos, plasma effects were also used. And simultaneously there was music etc. Does anybody know if there are some tricks for generating faster plasma routines? I also thought of using bitplane modulos to repeat every line 8 times. But when i want to add bobs to the screen, i have to change the blitter routines and so on....ahhh

Greetings Christian

You can use a combination of copper SKIP and COPJMP to create "loops"

So you only update 1 row, and it displays the same row of colour changes on 8 lines of the display.

There is a thread here somewhere explaining how to do it.

Thanks. That sounds promising. I will read more about this....

You could use a 32 colour mode and a background pattern to reduce the need of synchronisation.

Assuming OCS this is true, although this doesn't increase the horizontal chunky resolution, and impacts fillrate by leaving less CPU time to put an effect in the buffer.

To create a new realtime chunky mode, you can reach the resolution in Grade My Waterbear.

A lower such resolution remains the holy grail of chunky on OCS. <3

What i don't understand: How do i tell the copper to jump to a certain position?
From what i have read so far, i use the COPJMP1 register to jump to COP1LC. But what do i have to do if i want to jump to another position in my copper list? Do I have to update COP1LC inside my copperlist before jump?

Yes, that's exactly right. You set the correct value for the COP1LC in the Copperlist itself and then trigger the jump when needed.

It's often useful to keep COP1LC as is and instead use COP2LC and COP2JMP instead though, saves you resetting COP1LC every frame.

A very simple example can be found here.

I'm in the middle of trying to use copper loops to repeat an arbitrary length pattern starting and ending at arbitrary y locations.

What's tricky with copper loops seems to be that you need to correctly handle three different regions.

From y=0 to y=127:
This is easy enough with a wait for the end of line.

From y=128 to y=255:
You have to handle this separately because you can't mask the top bit for y.

From y=256 to y=312
This region is separate because there is only 8 bits for the y wait position.

All of that is a pain, but it's manageable for a copper list that starts and ends at a known location and it's easy if the loops land on the splits.

However, when trying to be more general I've found I need three more regions.

One to straddle the first region split.
A second to straddle the second region split.
A third to straddle the end of the third region.

This all gets more complicated than I'd like. So I'm curious if others have had to do the same or if there is something I'm missing?

As an example, imagine a 9 line repeating pattern starting at the usual y=44. That will not line up nicely for any of the regions splits.

I have a small problem with this approach. I listed the corresponding part of my copperlist. It seems that most lines are shifted 4 pixel to the left compared to the prior line (see image). Does it have to do with the execution time of the jump? If you look at the detail image, you see that for the first color (blue), there is no shifting starting at line 3. But from line 9 (green), every line is shifted. Any ideas? The first color of each row was set to a bright color to better see the results.

Your loop has 4*12+4=52 moves and a skip, so there's so still some time left in each rasterline. And since you don't have a wait in your loop to sync the start of each rasterline the moves to $182 are done immediately.

Ok thanks, working now (see image). But, now i would be glad if somebody could explain this a bit to a dummy like me

What does the

Code:

        dc.w $0084,$0000,$0086,$0000

do? I guess these are the COPL2C/COPL2H registers. But why do i write 0 to them in my copperlist?

Why exactly does it work with these extra waits? You mean i did not use enough horizontal waits?

Code:

       dc.w $003f,$80fe

And how does this init work? How does the copperlist know where to jump?Where does the copperlist distinguish between Copper_Line1,Copper_Line9,Copper_Line17 ?

I see that somehow, the addresses of my marks are written to the COP2LC/COP2LH registers here. But there is only one COPL2C/COPL2H....why does this work with more than one mark?

Code:

        lea.l	Copper_Line1-2,a0	
	move.l	#Copper_Line1,d0	
	move.w	d0,(a0)			
	swap	d0

You have to use an actual address instead of 0s (e.g. Copper_Line1, Copper_Line9, ...) with $0084 and $0086. That's how to you tell the copper where to jump when you hit the $008a trigger.
Also, if you can guarantee that the entire copper list is within a 64KB segment, you only have to set $0084 once at the start and then only update $0086.

The 0 values, are only placeholders, they are not used, but gets replaced by the init code.

	move.w	d0,(a0)
	swap	d0
	move.w	d0,-4(a0)

This part replaces the 0 values in the copper with the actual adress values for the different jumps in the copper. eg. Copper_Line1, 9 and 17.

It works with more than one mark, because copl2c+copl2h is pressent 3 times in the copperlist, one time for each segment.

It works by:

Code:

-- Wait for firstline of segment --
        dc.w $2c07,$FFFE
-- load copper 2 address with values set by init (copper_line1) --
	dc.w $0084,$0000,$0086,$0000

-- Wait for horizontal start of segment --
	dc.w $003f,$80fe
-- Spam colors --
	dc.w $0182,$0000,$0182,$0000,$0182,$0000,$0182,$0000,$0182,$0001,$0182,$0002,$0182,$0003,$0182,$0004,$0182,$0005,$0182,$0006
	dc.w $0182,$0007,$0182,$0008,$0182,$0009,$0182,$000a,$0182,$000b,$0182,$000c,$0182,$000d,$0182,$000e,$0182,$000f,$0182,$000f
	dc.w $0182,$000e,$0182,$000d,$0182,$000c,$0182,$000b, $0182,$000a,$0182,$0009,$0182,$0008,$0182,$0007,$0182,$0006,$0182,$0005

-- Wait for last line of segment, and if reached, skip the copper jump, else execute the jump  --
	dc.w $3401,$FF07

I have another problem with this. The example here works fine in WinUAE with 50fps, but when started on my A500, it seems that is has only 25fps. Does anybody have a clue what might be the reason? WinUAE is configured to "cycle exact"....no speed up for cpu etc.

It must have something to do with the blitter, because it only slows down when i am blitting. Any ideas?

But, again...in WinUAE i do not see that slow down. Only in real A500.

DanScott · 12 November 2021, 16:39

Do you have "immediate blitter" option set in WinUAE?

geldo79 · 12 November 2021, 17:11

No. Wait for blitter

In general, it works. In the copperlist, i wait for every line and change the background colour at every 8 pixels. In a routine, i update the colors using precalculated frames. This generates a nice effect, but as the routine has to update 40x212 colors (320 pixels = 40x8 pixels, and 212 lines ), the routine is rather slow. In principle, my routine can update the screen using frames with a resolution of 40x212 pixels (each color block 8x1 pixels). But i wanted the size of the precalculated frames to be small, and as i also wanted cubic color blocks rather than 8x1 pixel blocks, my frames have size of 40x27 color blocks (each block 8x8 pixel). But to produce the same line 8 times, i would also have to do the horizontal waits in all these lines ( like if i used the 8x1 blocks). Thus, i save memory, but not calculation time. In some demos, plasma effects were also used. And simultaneously there was music etc. Does anybody know if there are some tricks for generating faster plasma routines? I also thought of using bitplane modulos to repeat every line 8 times. But when i want to add bobs to the screen, i have to change the blitter routines and so on....ahhh Greetings Christian

And since you don't have a wait in your loop to sync the start of each rasterline the moves to $182 are done immediately. Last edited by a/b; 08 November 2021 at 13:52. Reason: typo*

There is a thread here somewhere explaining how to do it.

Jobbo Registered User Join Date: Jun 2020 Location: Druidia Posts: 387	I'm in the middle of trying to use copper loops to repeat an arbitrary length pattern starting and ending at arbitrary y locations. What's tricky with copper loops seems to be that you need to correctly handle three different regions. From y=0 to y=127: This is easy enough with a wait for the end of line. From y=128 to y=255: You have to handle this separately because you can't mask the top bit for y. From y=256 to y=312 This region is separate because there is only 8 bits for the y wait position. All of that is a pain, but it's manageable for a copper list that starts and ends at a known location and it's easy if the loops land on the splits. However, when trying to be more general I've found I need three more regions. One to straddle the first region split. A second to straddle the second region split. A third to straddle the end of the third region. This all gets more complicated than I'd like. So I'm curious if others have had to do the same or if there is something I'm missing? As an example, imagine a 9 line repeating pattern starting at the usual y=44. That will not line up nicely for any of the regions splits.

a/b Registered User Join Date: Jun 2016 Location: europe Posts: 1,039	You have to use an actual address instead of 0s (e.g. Copper_Line1, Copper_Line9, ...) with $0084 and $0086. That's how to you tell the copper where to jump when you hit the $008a trigger. Also, if you can guarantee that the entire copper list is within a 64KB segment, you only have to set $0084 once at the start and then only update $0086.
