Version 1.1.0

Two-Dimensional Cross-Section Model

This release extends the project from a single one-dimensional growth column to a two-dimensional cross-sectional model, representing the first step towards modelling stromatolite morphology rather than simply vertical growth through time.

Added

• Two-dimensional cross-sectional growth model.
• Independent vertical growth columns distributed across a horizontal substrate.
• Cross-sectional visualisation of stromatolite development through time.
• Time-series animation of evolving morphology.
• Additional diagnostic plots for interpreting spatial growth behaviour.
• Comprehensive project documentation and Wiki pages describing the new model and its outputs.

Model

The two-dimensional implementation treats each horizontal position as an independent one-dimensional growth model experiencing the same environmental forcing. Although neighbouring columns do not yet interact mechanically or biologically, their differing growth histories produce realistic large-scale stromatolite cross-sectional forms.

This architecture provides a direct extension of the validated one-dimensional model while establishing the framework for future spatial interactions.

Documentation

The accompanying Wiki has been expanded with:

• Two-Dimensional Cross-Section Model
• Interpreting the Two-Dimensional Model
• Updated Home page
• Revised descriptions of the core growth model and supporting processes

Looking Ahead

This release establishes the spatial framework needed for future developments, including:

• Lateral interactions between neighbouring microbial mats.
• Sediment redistribution across the surface.
• Fully three-dimensional stromatolite growth.
• More realistic domed geometries.

As with previous releases, the emphasis remains on building incrementally: extending the model while preserving clarity and physical interpretability.
