Thanks Patrice!
It looks especially good with slow jazz.

Hi,

first visualisation alternative preview is here
It should run on older PCs as well, as it does not use textures and very thin geometry is drawn - just lines.

Put your current RenderOpenGL sub in #IF 0 / #ENDIF and use this instead:

Bye,

[Kent Sarikaya]

Fun to see the new additions coming. Thanks for the new file support Patrice and of course scrub bar for the song!

Petr, that is a nice new visualization you came up with. It does work good with something with a strong beat, Cool stuff!!

[Charles Pegge]

Here's Another.

It's a modified BassBox.bas called BassBoxPoly, and a folder called ray.
To try them out, drop them into the bassbox_02 folder and compile BassBoxPoly.

The next step might be to set up some modulated lighting.

[Petr Schreiber]

Charles,

I knew your favourite geometry cannot miss
Looks really nice ! I like idea of constant color contours + changing areas.

I was playing with similar idea ( two "naked" orange (fruit) objects ), but I ended with lines I posted.

It would be nice if this visualisations could be each in one DLL, and user could pick one he likes.


Bye,
Petr

[Patrice Terrier]

Thank you very much both of you!

I am working on the BassBox visual section to let the user easily switch from one pluggin to another.

Keep them coming

Hi patrice

Amazing examples

it seems though i have a problems running your BassBox demo with vista home premium (no problems with xp pro sp2),
1, the main problem is your spinning cube visual appears twice,
the one that appears outside the main window runs perfectly smooth
and is positioned in the top left corner of my screen and over laps the main window visual in the top left corner of the demo,
also the visual in the main demo window doesn't run smooth(stops every few seconds then starts again)
2, also, when i minimize the main window my mouse pointer flashes erratically and tooltips from other apps do the same (including the taskbar)

sorry if it helps i am running vista on a laptop with onboard graphics,
CPU:  core duo T2080 1.73ghz
RAM: 1024mb
GFX:  ?? Intel 943gml(calistoga) + ICH7 - M with up to 128mb shared memory supports GMA 950 ??
with a screen resolution of 1400-900

sorry i cant give any pointers, (been a while since i coded)

keep up the amazing work 

[Patrice Terrier]

I have added a plugin section into BassBox and radio buttons to select the visual effect:




zskin.inc has been enhanced with zRadioButton control.


The plugin section looks like this:

'      The visual plugin section
       SELECT CASE LONG gnUseVisualEffect
           CASE 1: CALL Render1 (glDC, glRC, nLpeak, nRpeak)
           CASE 2: CALL Render2 (glDC, glRC, nLpeak, nRpeak)
           CASE 2: CALL Render3 (glDC, glRC, nLpeak, nRpeak)
           etc.
       END SELECT

Charles,
it would be nice if ALL the plugin code could fit within a RenderX procedure.
Instead of the dedicated BassBoxPoly file 

...

[Patrice Terrier]

Scott,

Better to use VISTA with 2048 Mb and a true graphic card, 
shared memory is a NoNo with OpenGL ...

...

[scott Stirling]

thanks patrice,

sort of guessed it would be a GFX problem my end,
and as soon as you post a reply you post another example including extra visuals
as i write this i have already hit the power button on my xp system so i can see it in action,
keep up the amazing work

ps thanks for the tips been looking into express gfx cards and audio cards and the memory is on its way
thanks again

[Charles Pegge]

Patrice, do have a place where Opengl objects can be initialised, before running the render frames?

I inserted a #include and also a call to my gllist code in your InitOpenGL function. Is that the best place to call it or do you want to use another location to initialise the plugins?

[Patrice Terrier]

Charles

Perhaps the good place could be in the procedure RenderOpenGL like this:

SELECT CASE LONG gnUseVisualEffect
    CASE 1
            CALL InitTHERE
            CALL Render1(glDC, glRC, nLpeak, nRpeak)
    CASE 2
            CALL InitTHERE
            CALL Render2(glDC, glRC, nLpeak, nRpeak)
etc.

And remember that the USER must be able to switch from one visual pluging to another at anytime.

Hi,

first I am angry to see Intels make some problems If the same Intel works under XPs and not under Vista than it is weird.
I have Intel powered notebook at home so I can test at least on XP soon.

Regarding visualisation - I like new update with choice of them !

Just one idea I of course steal from somebody else - thinBASIC is designed very nicely to be enhanced using modules - you just need to keep name of DLLs in one format + use special ( but very easy to use ) SDK.

If we could create "visualisation" SDK, all could be contented. Charles could initialize as he needs, and visualisation would be loaded dynamicaly, just looking after "BASSBoxVisualisation_<namehere>.DLL" in Visualisations or Plugins directory.

But current way works nice too, but it is less open.
I know it is lot of work to invent quality SDK, but in this case just few parameters could be exchanged.


Thanks,
Petr

[Charles Pegge]

Patrice,

Yes that will work. All we need is a static counter for allocating gllist numbers for different Opengl compiled objects, since these need to be persistent between frames, but each Plugin might require their own set of objects. Rather like issuing file handles.

Global Globjectcount as long

' only one function call per plugin would be required:
...

Static myGlobject as long
if myGlobject=0 then
 Incr GlobjectCount
 myGlobject=GlobjectCount
 initialise ...
end if
... renderiing frame


Petr,

The ultimate plugin would be the ability to drop DLLs into a folder and have them automatically recognised by Bassbox.

[Patrice Terrier]

Have you seen this?

Note: the 10-band equalizer is high on my todo list for BassBox
