mesh_handler

Provides some classes and methods for quick mesh generation and writing to .obj files. Allows mesh generation from a given parametrisation of a surface/manifold.

Since the second version it also supports the rendering of (simple) wireframes.

Wireframe rendering

One may launch the interactive viewer through

python3 wireframe.py out/torus.obj

or by

from mesh.obj import OBJFile
from viewer import Viewer

app = Viewer()
torus = OBJFile.read("out/torus.obj", axis="xyz")
app.scene.addObject(torus)
app.show()

Example code

from mesh.obj import OBJFile
from render.scene import *

scene = Scene(500, 500)  # specifying the width and height of the scene (in px)
apple = OBJFile.read("out/apple.obj", axis="xyz")
scene.addObject(apple)

scene.render()
scene.im.show()

The code above will generate the following image:
