16.2 Shadow

Archimedes can display projective shadows. To get a shadow, do the following:

• Select the light that will cast the shadow
• Select all objects that willl cast a shadow
• Select the object that the shadow should be cast on

This technique has its natural limits:

• Objects cannot shadow themselves
• The shadow will appear on the backside of objects, too
• The shadow will appear if the shadow-caster is behind the shadow-receiver

To compensate for those disadvantages the shadow will work in real-time, and it doesn´t need the latest graphics hardware!
