Module spyre.spyre

SPyRE -> Simple Pythonic Rendering Engine. A simple OpenGL rendering engine

Spyre has five types of objects which together make up the engine.

   Includes main loop, handles event queue, passing input data to 
   interface, maintaining viewport and tracking and displaying 
   objects.

   Controls the primary camera, the engine, and the timekeeper in 
   response to user input.

   Maintains eye position and direction of view, as well as projection
   config (frustum or ortho).   Different cameras are suited to different
   interfaces, but MobileCamera is common.

   Maintains lights, including fixed, mobile, and camera-mounted types; 
   and depth-cueing (fog) and some materials details.

   Controls pace of engine run, can switch engine advancement on and
   off.  Also controls and monitors framerate.

   In addition to the above five elements of the engine assembly, there are 
   displayable objects.  These all descend from the Object class.

   This is not tested. See scripts in demos directory for
   tested code.
   =========================
   import spyre
   import OpenGL.GLU as oglu

   # create displayable object, subclassing Object
   def Sphere(spyre.Object):
       def __init__(self, diameter): self.rad = diameter/2.0 
       def display(self):
           quad   = oglu.gluNewQuadric()
           oglu.gluSphere(quad, self.rad, 60, 60)

   sph = Sphere()
       
   engine = Engine()
   engine.add(sph)

   engine.go()
