GeoLoom: High-quality Geometric Diagram Generation from Textual Input

Abstract

GeoLoom proposes a novel framework for generating high-quality geometric diagrams directly from natural language descriptions. It addresses the challenges of precise spatial reasoning and visual coherence by integrating advanced deep learning models. Our method demonstrates superior performance in generating complex geometric figures with high fidelity and accuracy compared to existing approaches. This work significantly simplifies the creation of intricate diagrams, enhancing accessibility for various applications.

1. Introduction

Geometric diagrams are crucial in education and engineering but are labor-intensive to create manually. This paper introduces GeoLoom to automate this process by synthesizing precise diagrams from textual descriptions, aiming to overcome the limitations of existing manual and semi-automatic tools. Models used include a Transformer-based encoder for text understanding and a specialized Generative Adversarial Network (GAN) for diagram synthesis.

2. Related Work

Previous research in text-to-image synthesis has shown promise but often struggles with the precise geometric constraints required for technical diagrams. Existing diagramming tools offer rich features but lack automation from natural language input. GeoLoom differentiates itself by focusing specifically on geometric accuracy and high-fidelity rendering from free-form text.

3. Methodology

GeoLoom employs a two-stage architecture comprising a text encoder and a diagram generator. The text encoder processes the input description into a rich semantic representation, capturing geometric relationships and properties. This representation then guides a graph-based geometric renderer, which iteratively constructs the diagram by placing and connecting geometric primitives, refined using a perceptual loss function.

4. Experimental Results

GeoLoom was evaluated on a custom dataset of geometric descriptions and corresponding diagrams, demonstrating significant improvements in both quantitative metrics (e.g., intersection accuracy, angle precision) and qualitative visual assessments. Compared to baseline methods, GeoLoom consistently produced more accurate and visually appealing diagrams.Here are the performance results comparing GeoLoom against two baseline methods across key metrics:

Method	Intersection Accuracy (%)	Angle Precision (RMSE)	Visual Fidelity (FID)
Baseline A	68.5	0.15	45.2
Baseline B	75.2	0.12	38.9
GeoLoom	92.1	0.03	12.7

The table illustrates GeoLoom's superior performance, achieving significantly higher intersection accuracy and lower error rates for angle precision and visual fidelity compared to the baseline models.

5. Discussion

The results confirm GeoLoom's capability to generate highly accurate and visually consistent geometric diagrams from textual input, addressing a long-standing challenge in automated diagramming. Its strength lies in its ability to parse complex spatial relationships and translate them into precise visual elements. Future work will explore extending GeoLoom to 3D geometric representations and integrating interactive refinement capabilities.
