For making a 3D chain link fence with all its faces and vertices, see if you’ll flee with AN Opacity map material on a flat plane. 3D Walkthrough Use Bump maps and Opacity maps to make the illusion of 3D pure mathematics once none exists. Style your models with economical displays in mind. Don’t model elements of the building that may ne’er be seen within the final rendering.
The same 3D environment, it is also important not to let the characters walkthrough walls or various obstacles may occur along the way that must be avoided. Walkthrough means Step-by-step test of all aspects of an environment, plan, or process to verify it is ready for its intended purpose and 3D modeling nothing to need to observe and test all step by step environment and also not require verifying whole process because model is made by the collection of objects that show us model that will be done in future.
The requirements of 3D modeling are 3D model limitations, Materials, lighting and texture format. So they doesn’t need to everything do step by step or some observation because model is that only done by team work that only needs some objects and physical of building structure.
People only want their architecture that completely similar as architecture model demo. So studio have to do exact make model as requirement of client and save all data of their collection of data which are actually applied on their project. After they complete their work and they present their model in front of their client and aske to them that how is it. If model is good then client will be satisfied but if it is not good then company have to make changes in their model and make perfect.
