Adress + DrawFixed

vvvv beta question
1

Hello,

I am trying to use the DrawFixed node with a polygon mesh, to render some pictures or video on screen, but in other shapes than pure rectangles.

When I change the shape of my polygon, the texture gets deformed due to interpolation. I was hoping to be able to use the Address (EX9 SamplerState) node to disable this interpolation, so the polygon would just ‘cut out’ a smaller part of the texture, without deforming it.

So far no luck. Is this possible (with the DrawFixed node), and if so, which settings should I give the Address node in order to achieve this?

Thanks for your ideas…

can you please post the patch explaining the problem

Here is a patch explaining the issue.

i think its not possible with the address-node
but
try the TexCoords at the pin source e.g. position in space

the Address doesn’t help you at all here.

i would go for a solution based on Blend (EX9.RenderState) with Draw Mode set to ‘Multiply’

funny thing:
i had to recreate the Polygon (EX9.Geometry 2d) because the code was broken:

:PLUGINS:\2dMeshNodes.dll|VVVV.Nodes.Ploygon2dNode

Thanks everyone for the valuable input.

I will definitely take a look at TexCoords, a node I didn’t know yet…
