This Python script for Blender 3D creates an ovoid model using the math formula for ovoid:

Today I tested how to build Blender 3D from source development on my windows operating system, see the official webpage for more information. You need to use GitHub tools to get the source code from the Blender 3D project. You need to install CMake from this website and Subversion for Windows, then reopen the command… Read More »
The python language was mainly developed to emphasis on code readability. That’s why I think that it should not be affected by such errors, but they are easily fixed

If you do not have the experimental options set to the latest version of Blender 3D, then you may not have all the developer features available. Here’s how it’s activated: in the main menu select Edit – Preferences… and in the Interface area check the Developer Extras checkbox as seen in the screenshot:
You can render around an object 360 degrees with python script. Open your scene and add some lights, and a Susanne object on the origin point – this will be rendered by the camera. You need to have these names for the objects because are used by the script: Camera and Suzanne. If you want… Read More »
In this simple tutorial, I will show you how to create a docker in the Krita software and add some GUI elements with PyQt5. You need to take the docker template from the official page and modify it. After you download the zip, unzip the contents in the local pykrita folder. This can be found… Read More »
Today I will show you how can use Dynamic Language Runtime with IronPython. The dynamic language runtime (DLR) is a runtime environment that adds a set of services for dynamic languages to the common language runtime (CLR). The DLR makes it easier to develop dynamic languages to run on the .NET Framework and to add… Read More »
