Two 3D objects surfaces intersection contours.

Let's create a set of groups of line segments by intersecting the surfaces of two toruses.

The code of creating toruses and constructing a group of line segments from their intersection looks as follows:

sgCTorus* tor1 = sgCreateTorus(2,1 ,36,36);

sgCTorus* tor2 = sgCreateTorus(2,0.6 ,36,36);

SG_VECTOR transV1 = {1,1,0};

tor2->InitTempMatrix()->Translate(transV1);

tor2->ApplyTempMatrix();

tor2->DestroyTempMatrix();

sgGetScene()->AttachObject(tor1);

tor1->SetAttribute(SG_OA_COLOR,65);

sgGetScene()->AttachObject(tor2);

tor2->SetAttribute(SG_OA_COLOR,105);

SG_VECTOR transV2 = {5,0,0.0};

sgCGroup* bool1 = sgBoolean::IntersectionContour(*tor1, *tor2);

bool1->InitTempMatrix()->Translate(transV2);

bool1->ApplyTempMatrix();

bool1->DestroyTempMatrix();

sgGetScene()->AttachObject(bool1);

bool1->SetAttribute(SG_OA_COLOR,0);

bool1->SetAttribute(SG_OA_LINE_THICKNESS,2);
