glsurface 0.1.0

Some helper class

glsurface

glsurface is a python class to show show 2d data with wxpython and pyopengl.

Installation

$ pip install glsurface

Usage

1. Derived a class from TrackingSurface

   class Surface(TrackingSurface):
       def __init__(self, *args, **kwargs):
       TrackingSurface.__init__(self, *args, **kwargs)
       ...
   

2. Create an instance, and set data (optional)

   class SurfacePanel(wx.Panel):
   
       def __init__(self, parent):
           wx.Panel.__init__(self, parent, -1)
           ...
           self.x = np.linspace(0, 2 * np.pi, 30).reshape((1, 30))
           z = np.cos(self.x).T * np.sin(self.x)
           self.canvas = Surface(self, {'z': z})
           ...
   

3. Update the data
   1. Add the new frame data to the current frame buffer

      self.canvas.NewFrameArrive(z, silent=False)
      

   2. Or reset the frame buffer with new data

      self.canvas.SetFrames(points, reset_buf_len=True, silent=False)
