The uses of 3D

  • 3D graphics & Animation
  • CGI for Film (joining 3D graphics with real life footage and compositing)
  • Design (3D printing, Architectural pre-viz)
  • Gaming
  • Motion Graphics

The 6 steps of 3D Graphics

Lifeofpi.jpg

1. Pre-Production

  • Sketching
  • Defining color schemes
  • Storyboarding

2. 3D Modelling

Basic Modelling is made out of 2 types of objects. A 3D scene can be made out of a mix of these elements.

NURBS surface

A surface that is defined by 2 or more vector curves, and which the software connects. High level of mathematical precision and provides smooth surfaces

Polygon models

Start as a simple geometric shape, like a cube, sphere, or cylinder, which is then made more complex. This can be done by modifying or adding:

  • Faces
  • Edges
  • Vertices

3. Shading & Texturing

Defining the look of an object.

  • Define a Material = giving the object different properties (called shaders), for instance: color, transparency, glossiness etc etc
  • Adding textures = projecting a two dimensional image onto the model

Texture mapping:

4. Lighting

The key to realism!

  • Related to materials
  • Shadows

5. Animation

  • Motion Rigging
  • Pose-to-Pose (key-frame animation)
  • Physics (particles/collision/fluids)

Rendering & Post-Production

  • Finalizing Lighting: Shadows and reflections must be computed for each object.
  • Special Effects: This is typically when effects like depth-of-field blurring, fog, smoke, and explosions would be integrated into the scene.
  • Render Layers (for freedom in compositing)
  • Render Farms (using multiple machines to render a frame simultaniously) Although that might be history

3D Software

  • Maya
  • 3d Studio Max
  • Blender (python!)
  • Cinema 4D
  • etc etc
