Boolean union.

Let's create a group being a two toruses joining:

sgCTorus* tor1 = sgCreateTorus(2,1 ,24,24);

sgCTorus* tor2 = sgCreateTorus(2,0.5 ,24,24);

SG_VECTOR transV1 = {1,3.5,0};

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

tor2->ApplyTempMatrix();

tor2->DestroyTempMatrix();

sgGetScene()->AttachObject(tor1);

tor1->SetAttribute(SG_OA_COLOR,5);

sgGetScene()->AttachObject(tor2);

tor2->SetAttribute(SG_OA_COLOR,45);

SG_VECTOR transV2 = {-6.5,0,0};

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

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

bool1->ApplyTempMatrix();

bool1->DestroyTempMatrix();

sgGetScene()->AttachObject(bool1);

bool1->SetAttribute(SG_OA_COLOR,3);

bool1->SetAttribute(SG_OA_DRAW_STATE,SG_DS_FRAME);
