Welcome to Web Art3mis
Web Art3mis is a browser-based 3D model annotation and analysis tool.
How It Works
All annotation logic is performed locally in your machine using JavaScript and WebGL (via Three.js). For extended functionality, Web Art3mis communicates with servers via requests for tasks like saliency generation and defect detection.
Recommended Model Guidelines
For compatibility with Three.js, models must be in .obj format, triangulated (only triangles), and contain a single object.
Textures should be applied via .jpg or .png files.
Annotations are stored in .json format.
As the main logic of the app is processed locally, performance is dependent on your machine's capabilities. As an indication, a typical machine can support models with up to 2.2 million faces (approximately 200MB).
File
Import or export model, texture, and annotation files.
View
Adjust camera and model viewing settings.
Background
Configure background color settings.
Lights
Modify light positioning and intensity.
Modes
Switch between the different modes of Art3mis.
Annotate a Region
Use tools to create a Region of Interest (ROI) and attach metadata.
Edit Annotation
Edit the selected ROI.
Functions
Access functions for saliency calculation and heatmap generation.
Model Saliency
Generate saliency values for the 3D model by clicking the "Generate Saliency" button in the Tools Menu > Functions section.
Annotation Saliency
Generate saliency values for an annotated region by selecting the annotation under File > Generate Saliency.
Saliency Colormap
The ”hotter” the area, the higher the importance of the corresponding region.
Model Defects
Generate defect values for the 3D model by clicking the "Defect Detection" button in the Tools Menu > Functions section.
Annotation Defects
Generate defect values for an annotated region by selecting the annotation under File > Defect Detection.
Defect Colormap
The ”hotter” the area, the higher the importance of the corresponding region.
