MFC template for Freeframe source plugins (try it!)

[victimofleisure]

After I wrote the Whorld source plugin, I got the idea that it would have been handy to have some kind of template project to start from, along the lines of "TODO: add your drawing code here". I looked at the FreeFrame SDK, but it wasn't quite what I had in mind. I wanted something optimized for writing source plugins, rather than effects. Specifically, I wanted the template to mirror the structure of a typical MFC graphics app, with a surrogate main frame and view, so that drawing code could be transplanted from an app to a plugin with minimal modifications. For example, in Whorld, the view uses the exact same source file in both the app and plugin; the differences are simple enough to be managed with #ifdefs.

So I finally got around to making the template project. It's called FFSrcPlug. It has a rudimentary demo view which draws a bouncing ball, and it exposes a single Freeframe parameter (the ball speed). The plugin DLL and the template project sources are in the same zip file, which is here:

http://whorld.org/temp/FFSrcPlug-1.0.0.zip

I've only tested FFSrcPlug.dll under TZT and Resolume. If you can test it in other hosts and post the results here, I would be grateful.

Speculation: could it be that part of the reason why Freeframe source plugins aren't so common is because there wasn't a clear example to start from? If that's so, maybe this template will spark an explosion of cool source plugins! You never know...

wow thanks Chris

the sample plugin works in VJamm 3 and in VJOgold

Can i include this template in the offical sourceforge freeframe downloads?

Awesome work Chris. Are you on Opentzt.com forums yet? Do you mind if I mirror you post over there so some other opentzt users can get inspired?

let's have more freeframe synthesizers, why can't we take it from here?

this is great...

is anyone game to try and convert this into an xcode project for mac ppls?

karl?

Sure, lend me a mac :-)

I'll talk to Intrinsic if I can borrow his mac again, thenagain I think I got a XCode FF skeleton some where in the closet...

Sorry Doctor, the skeleton in my closet are GCC scripts, no XCode there

Compile freeframe:

gcc -DTARGET_OS_MAC -c -O3 FreeFrame.cpp -o FreeFrame.o -include MyEffect.h

Compile your effect:

g++ -DTARGET_OS_MAC -dynamiclib -O3 MyEffect.cpp FreeFrame.o -o MyEffect.o -include MyEffect.h

Make OSX dist:

mkdir MyEffect.frf
mv MyEffect.o MyEffect.frf/MyEffect
rm FreeFrame.o

The defs I needed to compile Intrinsics Win32.cpp and .h files on OSX:

#include <Carbon/Carbon.h>
#define         __stdcall
#define         APIENTRY
typedef         unsigned char           BOOL;
typedef         Handle                          HANDLE;
typedef         void*                           LPVOID;
#define         BYTE                    UInt8
#define         WORD                    UInt16
#define         DWORD                   UInt32
#define         LARGE_INTEGER   UInt64

copy the MyEffect.frf folder to your say isadora's plugin folder

You now got a OSX FreeFrame effect!

Yes, please!

>>>mirror you post over there so some other opentzt users can get inspired?

Yes again! I'm on the TZT forums, but it didn't occur to me to post there.

YAY!
