Conclusion

Problem Domain• 2D architectural drawings are commonly used.

• Producing a three dimensional (3D) plan is costly.

• Difficult to be satisfied with design by looking at 2D plans.

• 3D drawings take time and money.

• Producing multiple 2D drawings to refine design is also costly

• 3D home reconstruction

• 3D Object Reconstruction

• Interior and Exterior Design
