AEGP_FastBlur with EffectWorld?

[bbryabb]

I'm a bit out of my element here.  I'd like to use the FastBlur that is part of WorldSuite2, but in an effect, not an AEGP.  Is there a way to convert an EffectWorld into an AEGP_WorldH to feed into FastBlur?

if it's the input you'd like to blur, then you'll have to copy it's content

into a AEGP_WorldH.

however, if it's some intermediate, then you can enjoy both worlds by

creating an AEGP_WorldH and using AEGP_FillOutPFEffectWorld, which will

wrap the aegp world into an effect world, so you can access that one world

from both it's forms.

It seems AEGP_New requires a "AEGP_PluginID" - how do I get one in an effect?

[bbryabb]

Passing NULL for that argument works (not sure if that's morally unacceptable)

Your method works, and I can enjoy the wonder that is FastBlur now.  In case anyone finds this and is a bit confused as to what to do, it's something like this:

PF_EffectWorld effect_world;

AEGP_WorldH render_world;

ERR(suites.WorldSuite2()->AEGP_New( NULL,

                                        AEGP_WorldType_16,

                                        WIDTH,

                                        HEIGHT,

                                        &render_world));

ERR(suites.WorldSuite3()->AEGP_FillOutPFEffectWorld(render_world, &effect_world));

/*

    Do some stuff with your effect_world here!

*/

ERR(suites.WorldSuite2()->AEGP_FastBlur(STRENGTH, PF_MF_Alpha_STRAIGHT, PF_Quality_HI, render_world));

ERR2(suites.WorldSuite2()->AEGP_Dispose(render_world));

passing a NULL for plug-in ID is not only morally just, it is also your

civic duty.

seriously though, it's fine.

Doesn't your example copy the render worlds content into the effect world, so that the blurring has no effect on the effect world?
