  • 3D Printing: A manufacturing process where materials are joined or solidified under computer control to create a physical 3D object.

2. Dive into 3D Modelling

Essential Elements:

  • Vertices: The points in space (x, y, z) that define the corners or endpoints of a 3D shape.
  • Edges: The lines connecting vertices.
  • Faces: The flat surfaces enclosed by edges.
  • Mesh: A collection of vertices, edges, and faces that defines the shape of a 3D model.

  • Medicine: Assisting in complex surgeries and creating anatomical models.
  • Architecture: Developing detailed and accurate building models.
  • Entertainment: Producing animated films and special effects.

6. Virtual Reality (VR) and Augmented Reality (AR)

Definition:

  • Virtual Reality (VR): A digital experience that takes users into a simulated environment, disconnecting them from the physical world.
  • Augmented Reality (AR): Integrates digital elements into the user’s real-world environment, enhancing their perception of reality.

Applications:

  • Gaming: VR provides immersive gaming experiences, while AR games like Pokémon Go blend digital creatures with the real world.
  • Education: Both technologies offer interactive and immersive learning experiences, making complex concepts more accessible.

7. 3D Animation and Visual Effects (VFX)

Key Concepts:

  • Keyframing: Defining the starting and ending points of smooth transition.
