This blog post will navigate through the fundamental terminologies and concepts prevalent in 3D technology.

1. What is 3D Technology?


3D technology refers to the creation, manipulation, and representation of objects in three dimensions: width, height, and depth. Unlike two-dimensional (2D) objects, 3D objects have a sense of space and presence, enabling viewers to perceive them with a semblance of depth and solidity.

Key Concepts:

  • 3D Modeling: The process of creating a mathematical representation of a three-dimensional object.
  • 3D Rendering: The process of generating an image from a 3D model by means of computer software.
  • 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.

Popular 3D Modelling Software:

  • Blender: A powerful open-source tool for 2D and 3D graphics, full-on animations, sculpting, rendering, compositing, motion tracking, game creation, and more.
