Detailed Description

Abstract base class for EEPIC-drawable geometric objects.

This class serves as the polymorphic base for all geometric objects that can be rendered in EEPIC format. Each derived class wraps a concrete geometric object (Point, Segment, Polygon, etc.) and provides:

• A draw() method that generates the EEPIC LaTeX code
• Methods to query extreme points for bounding box calculations
• A clone() method for polymorphic copying

Memory Management

The wrapped geometric object can be owned by this class (to_delete=true) or externally managed (to_delete=false). When owned, the destructor will delete the wrapped object.

Creating New Drawable Types

Use the DEFINE_EEPIC_CLASS macro to create new drawable types:

DEFINE_EEPIC_CLASS(MyGeomType);
