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

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
