Color of the Model

[Anonymous]

I want to access the color of each face of body in Autodesk Fusion 360  . Following procedure I have tried


for (int faceLoopCnt = 0; faceLoopCnt < facesCount; faceLoopCnt++)
{
    Ptr<BRepFace> faceCurr = bfaces->item(faceLoopCnt);   
    Face faceData;   
    Ptr<Appearance> appearance = faceCurr->appearance();   
    int appearanceCount =(int) appearance->appearanceProperties()->count();
    string appearancePropertyName[100];
    for (int i = 0; i < appearanceCount; i++)
    {
        appearancePropertyName[i] = appearance->appearanceProperties()->item(i)->name();       
        if(appearancePropertyName[i]=="Color")
        {           
            short red1,green1,blue1;
            Ptr<ColorProperty> colorProperty = appearance->appearanceProperties()->item(i);   
            red1= colorProperty->value()->red();    
            green1 = colorProperty->value()->green();   
            blue1 = colorProperty->value()->blue();                                       
        }   
    }       
}

Which color property to use,

It is not giving proper output. (In both cases, values are not correct).
But (205,46,46) RGB color is expected.

Hi prashant,

There can different properties with same name "Color". Take Steel -Satin, there is "Color" property which defines the appearance color, and another one for Advanced Highlight Controls. You can distinguish them by the property id. You can refer to property list of Steel -Satin as following image.

It is not clear that why the color is not the value as expected. I did some tests locally, it worked fine. Maybe the appearance got from the face is not as expected. You can try to get apearance name or id to check if the appearance is what you expect.
