3D Geometry

Large number of images of high resolution are available to the researchers on request for academic (not commercial) purpose. These images may be used for reconstructing 3D model of the temples. Some examples of 3d models are also given. Viewing these 3d models require installing ‘MeshLab’ software which may be downloaded from the site (https://sourceforge.net/projects/meshlab/). 3D models (.ply file) of the following temples are available in the respective pages.

• Rasmancha (1600)
• Shyamrai (1643)
• Jor-bangla (1655)
• Kalachand (1656)
• Madanmohan (1694)
• Jormandir (1726)
• Radha Govinda (1729)
• Radha Madhav (1737)
• Nandalal (C. 1675)

Viewing 3D model using MeshLab requires following steps:

1. Download 3D model (.ply file) of the temple (instruction is given in the respective page).
2. Run MeshLab
3. Import .ply file
4. Use mouse for viewing: left button to change direction and scroller button for zoom in/out.

The suggested minimum system configuration is as:
3GHz Quadcore CPU with 8GB RAM
The viewer (with or without proper system) may see video of 3D reconstruction process on the respective pages. Video screen is divided into four quadrants and displays as follows.

1.	Top-left quadrant	:	Original images one by one in order
2.	Top-right quadrant	:	Pont cloud (collection of 3-dimensional points in space)
3.	Bottom-left quadrant	:	Surface generated on point cloud (Crude model)
4.	Bottom-right quadrant	:	Texture and colour imposed on the surface map

Important: Note that due to absence of proper image acquisition logistics, we could not acquire images from the top. As a result, the model is void of the roof (or, in other words, the top view of the temples is not available. Second, there are holes and vacant space in the generated 3D surfaces of the model as we have used only a small number of images to reconstruct it. This does not reflect the reality. This short coming is regretted.

Note: Dataset is available on request for academic (academic) purpose.
