3D Renderings can help inventors to sell their ideas to banks and investors. Great for designing, when your product is built in 3 dimensional space, it is easier to find any design flaws.
Do you have a great idea? A 3D rendering can help you to explain your product but also to show how it works and what it does. If you need investors a rendering can help to share your excitement with them. People like something they can see and visualize how it will work. This type of excitement can be created with some high quality 3D renders.
Another great tool for inventors is animation. Investors want to know how your product will work and what it will do. Mountains of paper work can tell them how or what it will do, but an animation can show them and help to build their excitement in a few short minutes.
