SHADOW FROM POINT TO FLAT GEOMETRIC OBJECT

SHADOW FROM POINT TO FLAT GEOMETRIC OBJECT

The shadow from point D to an arbitrary flat geometric object is the point D _{s of} intersection of the light beam S passing through the point D with this object.

Consequently, the construction of the shadow from a point on a flat geometric object consists in determining the point of intersection of a straight line (light beam) with this object.

Building a shadow from point D on a triangle ABC using a three-dimensional model.
