This also means that we are now ready to realize all your Plugin ideas.

Please contact us for more information.

**LON-LAT Connection Kit V1.0
**We are very proud to announce the release of the LON-LAT Connection Kit, a geo-location creation toolkit for Maxon’s Cinema 4D.

The kit enables the fast creation of Globe animations and contains a plugin and a library.

Click here for short overview.

It is available through our online-store www.editude.nl/c4d-plugin

**Latest tutorials / posts:**

**Python dialog tutorial**A tutorial explaining how to create a ‘floating’ dialog using Python.

**Adding User Data using Python**

A short tutorial on how to create User Data and how to read / write User Data using Python.**Update on “How to calculate Intersections”**

This tutorial is an update on the Tutorial: “How to calculate intersections” posted on my blog August 17, 2012. It was a more complicated tutorial on “How to calculate intersections of 2 lines (splines) using Python and Cinema 4D”.

However, the part on how to check whether the intersection was on the line segment, was not fully correct. Here an update.**Create the Matrix Rain effect using Python.**

A short and simple tutorial on how to create the Matrix Rain effect using Python.

It also explain how to blur it using the physical render.**GUI formatting with Python.**

A (paper) tutorial on creating and formatting GUI’s with Python.

It is the second in a series of GUI tutorials.

Here you find the first tutorial “Python dialog tutorial”.

**Coming tutorials (plans):**

- More tutorials in the series GUI tutorials.
- A more in depth tutorial on the Spline Data / Spline Control GUI
- Your requests for a tutorial.

**Newsletter 4, December 2012**

Sorry, it’s been a long time since my latest newsletter.

I have been very busy on 2 commercial plugins. The first will be announce within weeks!

In this newsletter an overview of the latest and coming tutorials (plans).

If you have any requests on tutorials, please let me know.

And of course, everybody the best wishes for a splendid, creative and learning 2013!

**Latest tutorials / posts:**

- A short and simple tutorial on how to calculate the angle between two points in the 2D space using Xpresso and Python.

It shows you:

– the math to calculate the angle between 2 points in the 2D space. Here the XZ plane

– Python to calculate the angle

– Using Python within Xpresso.

**Coming tutorials (plans):**

- A tutorial on selection neighboring polygons.
- A tutorial on menu’s.
- Your requests for a tutorial.

**Newsletter 3, October 2012**

In this newsletter an overview of the latest and coming tutorials (plans).

If you have any requests on tutorials, please let me know.

At this moment, I’m developing my first two commercial plugins, that keeps me busy quite a lot. So next month, there will be less posts / tutorials

If you have questions or ideas / requests for tutorials, let me know.

**Latest tutorials / posts:**

- Posterize files

A script (R13) + tutorial explaining the Python code behind it, to posterize files. - Tutorial: Calculate Voronoi using a brute method

This tutorial shows how to calculate (in Python) 2D Voronoi using a brute method. Voronoi is often used to scatter or explode objects. - Xpresso Logging Node

This**Xpresso Logging Node**can be used to log Xpresso information to a logfile.

**Coming tutorials (plans):**

- A tutorial on selection neighboring polygons.
- Your requests for a tutorial

**Newsletter 2, September 2012**

Here my second Newsletter.

Sorry, it has been a slow month, just one tutorial and one animation.

In this newsletter an overview of the latest and coming tutorials (plans).

If you have any requests on tutorials, please let me know.

**Latest tutorials:**

**Tutorial: Ray Collision Xpresso Node**Posted on September 25, 2012

The node is used to get the polygon(s) that was ‘hit’ by the Ray.

Python is then used to get the neighbor polygons.

All these polygons are added to the Polygon Selection Tag.What you will learn:

– Use of the Ray Collision Xpresso node.

– Interface Xpresso to Python

– Get Neighbor polygons in Python

– Set selection tag in Python

Coming tutorials (plans):

- A tutorial on how to calculate Voronoi using a brute method.

Voronoi is often to scatter (explode) objects.

**Note:** In mathematics, a Voronoi diagram is a special kind of decomposition of a metric space, determined by distances to a specified family of objects (subsets) in the space.

- A tutorial on creating a Python script to ‘posterize’ files.

Algorithm: Based on given factor, calculate average pixels color and create an object (Cube or Sphere) and a material with the calculate average color. Assign the material to the object.

** Animation:**

- Wormhole.

A small VJ test with self composed music.

**Newsletter 1, August 2012**

Here my first Newsletter.

Thanks for all the positive feedback.

If possible please give me your examples / projects were you used the knowledge gained with my tutorials.

If you have any requests on tutorials, please let me know.

**Latest tutorials:**

- Tutorial: Create objects, mats and tags

Posted on August 31, 2012

A short and simple tutorial on how to create an object, a material and assign that material to the new object (texture tag) using Python and Cinema4d.

Some basic stuff that you can use in other scripts and plugins.

It also explains how to get the ID of an item.

- Tutorial + Plugin: How to create your own Python Plugin

This tutorial shows you how to create your own Python plugin.

The plugin adds or subtracts selections.The tutorial will explain:

– Plugin structure

– Register plugin

– GUI with Link object and Combobox

– Read, create and write selection tags

– Checking and handling error.

- Tutorial: How to calculate intersections

Posted on August 17, 2012

A more complicated tutorial on “How to calculate intersections of 2 lines (splines) using Python and Cinema 4D”.I explain the various ways, lines (segments) can intersect (parallel, coincide, skew or intersect). Please have a look on the Internet for the mathematics of intersecting, skew, coincide, etc.The tutorial will explain:

– Some basic mathematics on line intersections

– Cinema 4d vector handling with Python

– Cross and Dot product

– Round function

– Spline / SplineHelp functionality
