Go, change the world
 This Project will focus on direct reconstruction of the historical
monuments using Blender, a open-source 3d render using images
and GIS as the reference.
 Using images and information available the monuments will be
covered in textures for a realistic and clear understanding of the
monument.
 The Project will also utilize Unity, a game development engine to
develop a virtual world for the virtual inspection of the monument.

 This Project will focus on 3D reconstruction of the historical
monuments using Blender, a open-source 3d render using images
and Images as the reference.
 Using images and information available the monuments will be
covered in textures for a realistic and clear understnding of the
monument.
 The Models will be reconstructed using the images using pixel
extraction from the images and Mesh conversion techniques.

Design and Implementation
• The algorithm uses images from a pre-specified directory and
runs masking applications such as GAN.
• GAN Networks are used so as to distinguish the required
image from the background image.
• The output of the GAN Networks is used to separate the
foreground of the image from the background.
• The extracted Image is then imported into the Blender.
• Blender imports these images as planes with each of the pixel
as a vertex.
• The RGB values of the pixel is used to determine the color of
the vertex.
Design and Implementation
• The algorithm then performs certain optimizations to reduce
the number of pixels for easier rendering.
• The algorithm then performs the above mentioned steps for
multiple such images and stores the meshes.
• The meshes are then applied with the solidification modifier
and the meshes are thickened
• The meshes are then aligned together by performing regular
checks with the mesh collision and overlapping and is brute-
forced along the axises until they form a perfect structure.
• The excess of the mesh is then trimmed using the Boolean
modifiers based on their overlaps and the solidification
modifier is removed to obtain the final mesh.
