    3.  Lighting: Lighting helps set the mood and brings your 3D model to life. It creates shadows and
                        highlights, adding depth and realism to the model.

                     4.  Rendering: Rendering is the final step, where the model is prepared for use in animation. It
                        combines all the previous steps into a final, ready-to-view animation or 3D model.

                               UNDERSTANDING 2D AND 3D OBJECTS

                     In  the world of shapes and geometry,  we often come  across two types  of figures:  2D or

                     Two-Dimensional shapes  and 3D or Three-Dimensional objects.  Understanding  the difference
                     between them is important, especially when learning about modelling and design

                     WHAT ARE 2D SHAPES?

                     A Two-dimensional shape is flat and has only two dimensions: length and
                     width. These shapes do not have depth and cannot be picked up or held.
                     They can only be drawn on paper or seen on a screen.

                     Examples of 2D shapes: Circle, Rectangle, Star, Cloud and Triangle.
