Phil 12.28.12

8:00 – 12:00 ESSO

  • Walked through some bugs with Lenny.
  • Attempted to back up but the connection with PuTTY was way slow. It seems to be a known problem, so I’ll wait until Monday to try again.
  • Helped Brian out with some JavaScript/HTML that handles collapsing tables. The code was not written well to educate.

12:00 – 4:00 FP

  • Got the HLAPI demonstration code compiled, though some things run and some things don’t. I get errors like “Haptics failed to initialize”. Still, “HelloSphere” works, which is enough to get the hang of things.
  • Hmm. Looks like it’s written for OGL 1.x?
  • Still, pretty cool. I’ve got a rotating cube with appropriate forces:

  • Also a teapot. So arbitrary geometry seems fine.
  • Still, I don’t like this:
	// Start a new haptic shape.  Use the feedback buffer to capture OpenGL 
	// geometry for haptic rendering.
	hlBeginShape(HL_SHAPE_FEEDBACK_BUFFER, gSphereShapeId);
  • That does mean OGL 1.x. No feedback buffer in OGL 3.0 or greater. That means this library probably won’t be all that useful.
