示例1: calcShadowPlane
void EG_Object::calcShadowPlane(const EG_Polygon *surface,
EG_Object *shadowObject)
{
Point3D onePoint;//a single point from the surface
Matrix3x3 surfaceRotate;//rotates surface points to the surface's orientation
surfaceRotate.fromEuler(shadowObject->getRotation());
for (unsigned int i = 0; i < 3; i++)
{
//### Rotate the point ###
onePoint.copyFrom(surface->getVertex(i));
onePoint = surfaceRotate.rotatePoint(onePoint);
//### Translate to the surface's position ###
onePoint.x += shadowObject->getPosition().x;
onePoint.y += shadowObject->getPosition().y;
onePoint.z += shadowObject->getPosition().z;
shadowPlane.at(i)->copyFrom(onePoint);
}//for i

vector<GLdouble> testVertices;
