In this tutorial, we will create and connect quaternions. We will create multiple geometric objects in a 3D scene and use quaternions to rotate these objects. By comparing multiple geometric objects, we can clearly see the differences.
You can write code here to use Aspose.3D and run the code in browser to see how it works.
Step 4 of 4: The following code demonstrates how to rotate a geometric object using a quaternion q3.

//Create a new 3D scene
Scene scene = new Scene();
//Create quaternion q1
Quaternion q1 = Quaternion.FromEulerAngle(Math.PI * 0.5, 0, 0);
//Create quaternion q2
Quaternion q2 = Quaternion.FromAngleAxis(-Math.PI * 0.5, Vector3.XAxis);
//Concatenate q1 and q2. q1 and q2 rotate alone x-axis with same angle but differentdirection,So the concatenated result will be identity quaternion.
Quaternion q3 = q1.Concat(q2);
// Create a cylinder to represent q1 quaternion
Node cylinder = scene.RootNode.CreateChildNode("cylinder-q1", new Cylinder(0.1, 1, 2));
cylinder.Transform.Rotation = q1;
cylinder.Transform.Translation = new Vector3(-5, 2, 0);
// Create a cylinder to represent q2 quaternion
cylinder = scene.RootNode.CreateChildNode("cylinder-q2", new Cylinder(0.1, 1, 2));
cylinder.Transform.Rotation = q2;
cylinder.Transform.Translation = new Vector3(0, 2, 0);
// Create a cylinder to represent q3 quaternion
cylinder = scene.RootNode.CreateChildNode("cylinder-q3", new Cylinder(0.1, 1, 2));
cylinder.Transform.Rotation = q3;
cylinder.Transform.Translation = new Vector3(5, 0, 0);
