HI，

I want to display a colored cylinder(points cloud) section by section. I used AIS_PointCloud to show the clound,but cann't show, who tell me or share code to me ,thanks.

Handle_AIS_ InteractiveContext m_ AISContext;
Handle(Graphic3d_ArrayOfPoints) aPoints = new Graphic3d_ArrayOfPoints (2000, Standard_True);

aPoints->AddVertex(gp_Pnt(-40.0, -40.0, 0), Quantity_Color(Quantity_NOC_BLUE1));

aPoints->AddVertex(gp_Pnt(40.0, 40.0, 0), Quantity_Color(Quantity_NOC_BLUE2));

Handle(AIS_PointCloud) aPntCloud = new AIS_PointCloud();

aPntCloud->SetPoints(aPoints);

m_AISContext->Display(aPntCloud);

Hi,

A solution to your problem could be :

a_occPc = new AIS_PointCloud();

Handle_Graphic3d_ArrayOfPoints arrayPoint = new Graphic3d_ArrayOfPoints(mycloudSource->size(), true, false);

for (Standard_Integer ii = 1; ii <= nbVertices; ++ii)

{

gp_Pnt point(mycloud->points.[ii].x, mycloud->points[ii].y, mycloud->points[ii].z);

Standard_Real r = ...;

Standard_Real g = ...;

Standard_Real b = ...;

Quantity_Color aColor;

aColor.SetValues(r, g, b, Quantity_TOC_RGB);

arrayPoint->AddVertex(point, aColor);

}

a_occPc->SetPoints(arrayPoint);

m_AISContext->Display(_m_occPc);
