pyViz3D is a lightweight OpenGL-based Point Cloud visualization library, which is primarly designed for research and debug purposes.
from viz3d.window import OpenGLWindow
from viz3d.engineprocess import *
window = OpenGLWindow()
window.init() # Starts the engine in a new process
pc = np.random.randn(100, 3).astype(np.float32)
color = np.random.rand(100, 3).astype(np.float32)
window.set_pointcloud(0, pc, color) # Sets a colored point cloud model for id=0
...
window.close(force=True) # Closes the window (forcing the process to close)
The user can navigate in the window with a
First Person Camera, which has the following key binding:
| Key Pressed | Action *(IF THE CAMERA IS ACTIVATED) |
|---|---|
| Z | move Forward |
| S | move Backward |
| Q | move Left |
| D | move Right |
| R | move Up |
| F | move Down |
| A | rotate clockwise in roll |
| E | rotate counter-clockwise in roll |
| SHIFT | Accelerate camera motion x 10, while the key is pressed |
| Mouse Action | Action |
|---|---|
| Right Click | Activate/Deactivate the Camera |
| Move the cursor away from the center | yaw, pitch orientation changes IF THE CAMERA IS ACTIVATED |
To Install the pyViz3d as a python module:
pip install .
- Switch from pygame to glfw
- Improve the camera
- Improve the documentation
- Robustify the suppression of the engine process if the origin process dies unexpectedly
