Blender 3D – sin mesh object with python.
This is a simple example of create one object from vertrices and edges using sin function. First you need to create the mesh with: bpy.data.meshes.new . The n number is random, you can use any number for vertices and edges. This number is points for the drawing sin function. The spaces variable is the range […]
Create a starfield with Three.js .
You need to create two files into your folder and use this filenames : index.html and starfield.js . First file index.html come this source code:

1 2 3 4 5 6 7 8 9 10 11 |
<!DOCTYPE html> <html > <head> <meta charset="UTF-8"> <title>WebGL Tunnel</title> </head> <body> <script src='https://cdnjs.cloudflare.com/ajax/libs/three.js/r70/three.min.js'></script> <script src="starfield.js"></script> </body> </html> |
The next file is a java script and come with this source code:
