Generating tree structures representing placental anatomy

This set of examples demonstrates the steps toward creating models of placental tree structures. These tree structures could be representations of villous trees themselves, or the placental vascular trees that reside within them.

• The theory
• The basics
• Generating a tree structure that fills an cuboid
  • Step 1 - Define a seed geometry from which to grow (stem villi)
  • Step 2 - Create a uniformly spaced set of seed points within the cuboid
  • Step 3 - Grow into volume
• Generating a tree structure that fills an ellipsoid
  • Step 1 - Define a seed geometry from which to grow
  • Step 2 - Grow branches over the ‘chorionic surface’
  • Step 3 - Create ‘stem villi’
  • Step 4 - Grow into volume
