Hi all,

I’m created a helper deriving from dummy and assign it a mesh do draw by using getDisplayMesh. To be more precise, I just have a local var of type TriMesh that I build using setMesh. The look is wireframe and this is fine with me

So my problem is that I want to draw with differents colors depending on various parameters. I’ve been setting vertex colors using SetVertColor and set the showVertexColors to true but it’s not working.

Is my approach wrong ?

Are you building a simple plugin?
You should have a look at meshop mapfaces, vertex colors live in the UV map channel, it's in UVchannel 0 to be precise. So getMapFace and setMapFace and get and setMapVert would be the tools needed to set the vertex colors.

Hum it seems that helper doesn't allow vertex color usage so I switch my object type to simpleObject. It works but only in the perspective viewport and it's not in wireframe.

Other viewports doesn't that colors in account..

I'm wondering if drawing directly on the viewport using gw functions could do the job but it's only drawing in the active viewport which again, so that won't do it.
