LO 1 Understand 3D character modelling techniques used
in media products
P1) 3D Character Modelling
Techniques:
Research and
explain three character modelling techniques used in existing games.
i)
Modelling process
e.g. Polygon modelling, NURBS modelling, sub divisional modelling, extruding 3D
shapes.
ii)
Animation / motion Generation e.g. How characters /
objects move in a 3D environment, use of lights, cameras, textures.
iii)
Application e.g.
How and where are 3D characters used in computer / console games, animations,
live action.
Create a word document report
explaining the three above elements.
Create an analysed report,
approximately a page and half with relevant images for each question.
3D Character Polygonal Modelling
Start to use the blog to help you understand the process of modelling and all components that come with it.
Nurbs
Understanding NURBS
Non-Uniform Rational
B-Splines (NURBS) and is simply the name for the mathematics that is used to
create the geometry in Alias, and in many other CAD systems.
Luckily, no understanding of
the math is required to become an expert Alias user. There are a few technical
terms that are used for controlling the shapes we design, but they are simply
learned as each tool is learned, and don't need to be understood in a
mathematical way.
The key benefit of NURBS is
that it isn't an approximation of a smooth shape. The math calculates an
accurate definition of the surface shape which is still smooth however closely
the surface is examined.
Why NURBS are used
More important than the
underlying math is understanding what unique features Alias NURBS has to offer
you as a designer, compared to the other software tools you may be using:
- Flexibility to create
sculptural shapes
- Tension to keep surfaces
smooth and taught
- Alignment to create
smooth, invisible joins
Designing with this level of
attention to sculptural aesthetics is a specialised area of CAD modelling,
typically used for premium products where elegance and surface quality are
important factors in the product's appeal.
