Game Dev

Prodominant Modelling Paradigm:

  • Triangle Mesh
  • GPU
  • Scanning = Model Acquisition

Solid Modelling:

  • Contructive solid geometry
  • Implicit modelling

Video: Cubic Tradgedy

Solid modelling / Implicit modelling

  • Modelling for computer graphics
  • Curisosity driven research

Important Dates:

  • Ricci 1973
  • Blinn 1981
  • Nishimura 1985
  • Wyvills 1985

Modeling:

  • Implicit surfaces
  • Contours (several)
  • Functions

Proximity Blending: add contributions from generating skeletal elements in the neighboouhood.

The blobtree: skeletal primitives. resulting shapes.

The great train rubbery 1986/88

Wraping: example vector warp

Barr operators:

  • Twist
  • Taper
  • Bend

Deformations

CSG intersection value

CsoftG wheels 1997

Canmore Coffee Grinder

Ray traced by kees van overveld and brian wyvill

Original Teapot Render.

l-system plant (generating branch structures)

The blobtree 1996

Precise contact modelling controlled blending and PCM

Collars and scars -> visualize tree growth

Inverse modelling

Sketch based modelling with the blobtree

Shape Shop - Ryan

  • Sketch based interactive modelling

Improvement

A single oriented implicit decal

Matisse

Decals spans all surfaces

Is uni modelling research dead?

  • Geologist
  • SIGGRAPH

  • William rowan hamilton plaque

Gimbal lock apollo 11 --> quaternion methods

Beware of knowing the price of everything an the value of nothing!
