In Cinema 4D, I have used generators with lathe, extrude, and sweep. I have used lathe and extrude before but have not used sweep before.
In Lathe, I have created the bottle which is similar to a coke bottle. I used spline with bezier and lathe, then linked them to create the bottle. The lathe tool is used to make objects like a bottle, vase, candle, perfume holder etc and gives it shape and body for a real appearance.
I have made this Pepsi bottle using Lathe. I am very confident how to use Lathe now.
Extrude is when you can make anything you like and also you can draw or create in 2d shape and turn into 3D shape by using Extrude.
Experimented to create my name in 3D text by using Extrude.
Also, did another experiment with extrude and using the spline tool with freehand to join together to create funny looking shapes. I am feeling confident to use the various tools and feel more experienced now.
I have never used sweep before so experimented using C4D tools like circle, spline and sweep joined together to create this snake like image. Amazed at how the images take shape and enthralled by all the creative possibilities as I learn and practice more.
