1 : Explanation of a basic 'Mesh'
A 3D mesh is a structural representation of a three-dimensional model that uses polygons to define shapes with height, width, and depth. 3D meshes are made up of points, lines, and faces that are used to define the shape of the object. Points are called nodes or vertices, lines are called edges, and faces are called polygons or surfaces. 3D meshes use reference points in X, Y, and Z axes to define the shape. 3D meshes are the structural base of a 3D model and do not have color or textural properties.
2 : UV unwrapping
3D UV unwrapping is the process of flattening a 3D model into 2D space to create a UV map that projects 2D textures onto the model's surface. UV unwrapping generates UV coordinates for each vertex in the object, allowing you to map points on the surface of the object to pixels in your texture image.
3 : Texturing
3D texturing is the process of adding textures to 3D models and environments for films, TV shows, and games. It involves creating textures, applying them to the model, lighting the scene, and adding final details. 3D texturing is similar to painting, adding designs to make a 3D shape seem more interesting, colorful, and alive.
4 : Lighting
3D lighting is the use of light and shadows to create a computer-generated scene. Lighting artists use 3D software applications to simulate natural light, mimic real-world behavior, and add realism to a scene. 3D lighting techniques are flexible and can operate at different levels of complexity. They offer a great deal of freedom in terms of detail and function.
5 : rendering
( Exporting )
3D rendering is the process of creating a photorealistic 2D image from 3D models. 3D rendering is the final step in the process of 3D visualisation, which involves creating models of objects, texturing those objects and adding lighting to the scene.
