What is drawMode ColorAsAlphaAdd?

vvvv beta question
1

Hello vvvvriends :)

i have to reference vvvv shader Settings to another Software developer.

i want to tell them to use the drawmode ColorAsAlphaAdd in their Software.

a quick Google search didnt Show any results outside of vvvv,
since im not a “gpu/shader-guy/gal” i dunno what i have to search for.

any tips what this drawmode could be named in other Software?

thank you!!!

Alex.

i tried with blend(advanced) and for me it seems that

ColorAsAlphaAdd

SourceBlendMode=SrcColor
DestBlendMode=SrcAlpha

can someone please confirm?

drawmodes are defined as:

Add:

  • SRCBLEND = SRCALPHA
  • DESTBLEND = ONE

Blend:

  • SRCBLEND = SRCALPHA
  • DESTBLEND = INVSRCALPHA

ColorAsAlphaAdd:

  • SRCBLEND = SRCCOLOR
  • DESTBLEND = D3DBLEND_ONE

ColorAsAlphaBlend:

  • SRCBLEND = SRCCOLOR
  • DESTBLEND = INVSRCCOLOR

Multiply:

  • SRCBLEND = DESTCOLOR
  • DESTBLEND = ZERO
