Performance Tips

• Use numexpr for fast expression evaluation
• Optimize sample count for better live animation
• Avoid super heavy curves
• Try to keep expression complexity low

Expression Engine (numexpr)

The add-on uses numexpr instead of Python eval:

Benefits

• Faster evaluation
• Prevents arbitrary code execution
• Vectorized math
• Safe execution sandbox

Supported features

• All NumPy-compatible functions
• Elementwise operations
• Logical and comparison operators

Live Update System

Live update regenerates the curve automatically when:

• parameter value changes
• domain or sample count changes

Add-on Architecture

Main components:

Function Engine

• Expression parser → variable detection → parameter detection
• numexpr evaluator
• Grease pencil generator

UI Panels

• Function panel
