TRIDENT (Tri-Dimensional Embeddings Navigation Tool)

TRIDENT is a Blender add-on for generating 3D visualizations from dimensionality-reduced data such as UMAP, t-SNE, and PCA. It uses the EEVEE rendering engine for real-time navigation, category-based color labeling, and export of publication-grade images or animation frames.

Overview

TRIDENT transforms Blender into a scientific visualization environment. You can import embeddings from CSV files, render them as point clouds, assign category labels, and capture high-quality figures or animations directly within Blender’s interface.

Features

Data Import and Setup

TRIDENT reads CSV files where each row represents a data point in reduced-dimensional space.

Supports:

• XYZ coordinates (UMAP, t-SNE, PCA, etc.)
• Optional metadata columns for labels or grouping

Interactive 3D Exploration

After import, TRIDENT plots your data directly in the Blender viewport using the EEVEE renderer.

You can:

• Navigate freely through data clusters
• Toggle categories or classes on and off
• Adjust transparency and palettes

Scientific Visualization in Blender

TRIDENT turns Blender into a figure-generation tool.

You can:

• Export publication-ready stills
• Render camera flythroughs
• Reuse lighting and material presets

Roadmap

• Improve label handling and legend sorting
• Add support for point clouds and multiple plots across scenes
• Enable cluster management with options for merging, separation, and color-based visualization
• Introduce color animation, text, and image annotations within clusters
• Enhance usability with UI and UX refinements

Once installed, TRIDENT appears in Blender’s sidebar (press N to open the sidebar).
