This extension will be added to the main menu at Extensions – Extensions by catafest – catafest test – 001. Open the Inkscape software and from the menu choose: Edit – Preferences – System and look for… Read More »
This Python script for Blender 3D creates an ovoid model using the math formula for ovoid:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 | import bpy import math # Define the parameters of the ovoid a = 1.9 b = 1.5 c = 1.5 # Define the number of vertices in each direction n_long = 32 n_lat = 16 # Create a new mesh mesh = bpy.data.meshes.new(name="Ovoid") # Create the vertices verts = [] for j in range(n_lat): lat = (j / (n_lat - 1)) * math.pi for i in range(n_long): lon = (i / (n_long - 1)) * 2 * math.pi x = a * math.sin(lat) * math.cos(lon) y = b * math.sin(lat) * math.sin(lon) z = c * math.cos(lat) verts.append((x, y, z)) # Create the faces faces = [] for j in range(n_lat - 1): for i in range(n_long - 1): v1 = j * n_long + i v2 = j * n_long + i + 1 v3 = (j + 1) * n_long + i + 1 v4 = (j + 1) * n_long + i faces.append((v1, v2, v3, v4)) # Create the mesh and object mesh.from_pydata(verts, [], faces) obj = bpy.data.objects.new(name="Ovoid", object_data=mesh) # Add the object to the scene scene = bpy.context.scene scene.collection.objects.link(obj) |
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

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 »
Collaboratory, or “Colab” for short, is a product from Google Research. Colab allows anybody to write and execute arbitrary python code through the browser and is especially well suited to machine learning, data analysis, and education. More technically, Colab is a hosted Jupyter notebook service that requires no setup to use, while providing free access… Read More »
