Hair-dos, Hair-Don'ts

There were some positive aspects to Maya's MASH networking in placing David's hair-cards.

• It was fast
• There was the ability to add randomness in scale, tangent angle and placement
• Many cards could be placed automatically, covering the entire surface of the scalp

Hair-cards applied using MASH

The results initially looked promising but did reveal a number of problems.

• It was unpredictable
• Many cards became clumped at peculiar angles
• The process removed the individual pivot point of each card making adjustments from the root and manipulation difficult.
• While visually effective from frontal angles, other angles proved much less satisfactory.
• This would require a lot of time consuming manual adjustment made more difficult by the heavily overlaid geometry and pivot placement

I made the decision to go "fully manual" and restarted the process. The new set of cards were created, pivot points adjusted and the geometry manually placed.
