I'm currently creating triangles with this methods :
Graphic3d_Array1OfVertexNC and Aspect_Array1OfEdge.
Then I draw my array of triangles like this :
Handle(Graphic3d_AspectFillArea3d) myFillAspect = new Graphic3d_AspectFillArea3d();
Handle( Graphic3d_Group ) TheGroup = Prs3d_Root::CurrentGroup(aPresentation);
Graphic3d_MaterialAspect mat = myFillAspect->FrontMaterial();
//Material Aspect personnalisation
This is good working but OpenGl use a linear interpolation between vertices. You can see the capture.
For some triangles, the renderer is not good, I would like a more smooth rendering.
How can I activate a spline interpolation between vertices instead of a linear interpolation ?
Many thanks for your help.
