|Bulb Modelling Tutorial - Page 1
|I've not attempted a tutorial
on modelling before, and it is not my intention to explain what the effect
of each tool used in the process is, but to give an overview of the process
itself. This tutorial is not aimed at beginners to C4D - it assumes that
you know how to use the poly modelling tools and how to navigate the various
attribute panes in the program. A fellow emailed me asking how to do the
base of a lightbulb, as seen in a couple of my renderings,
so I thought this would make a good subject to introduce a few concepts.
There are a LOT of pictures so this tutorial is spread across a number of
pages. Lets begin:
I used Adobe Illustrator to create the curve for the outline of the bulb
itself. I could have taken a photo of a lightbulb, but being lazy, I used
Google Image finder to locate one from the internet. A quick trip through
photoshop straightened the image up, and I placed the photo into Illustrator
to use as a guide. Here I have placed a guide through the center of the
photo, and have drawn a bezier curve around the glass portion of the bulb.
You could simply use the bezier curve tools in Cinema 4D to do this, but
the next couple of steps will show you why I chose not to.
I gave the curve I drew thickness by increasing the stroke value. In this
example I used 3 points so that the effect would be visible in this tutorial.
In practice, the real thickness of a lightbulb glass would be 1 point or
less. Once I am happy with the curve, I chose Object/Path/Outline Stoke.
This turns my single line bezier into a precise width double line - something
extremely difficult to do with Cinema 4D's bezier curve tools.
