* For some reason, the interior surfaces are shinier than the exterior
- surfaces. I don't understand why, but this should be remedied.
+ surfaces. Not sure why.
- * Perhaps use a slightly-bumpy or oily texture for the interior surfaces?
+ * Should use a dark wood-grain texture for the interior surfaces.
- * Some of the edges don't line up perfectly (since the images are not
- perfectly symetrical.) Something should be done about this; either
- making the edges overlap slightly (instead of leaving gaps) or fixing
- the images so that the edges may be symmetrical.
+ * Building a face out of multiple adjacent triangles was a terrible
+ idea and leads to visible seams. Should re-do the face generation
+ to make all of them out of a single triangle strip instead.
+
+ * The coordinates are slightly off from the image. lament512.gif is the
+ "right" one, and "lament512b.gif" is the image corrected to line up
+ with what the code is actually doing.
+
+ * The "star" slices really don't line up well.
* I want the gold leaf to seem to be raised up from the surface, but I
think this isn't possible with OpenGL. Supposedly, OpenGL only
and shading smoothly) but bump-maps only work with Phong shading
(computing a normal for each rendered pixel.)
- * As far as I can tell, OpenGL doesn't do shadows. As a result, the
- forward-facing interior walls are drawn bright, not dark. If it was
- casting shadows properly, it wouldn't matter so much that the edges
- don't quite line up, because the lines would be black, and thus not
- visible. But the edges don't match up, and so the bright interior
- faces show through, and that sucks.
-
- But apparently there are tricky ways around this:
- http://reality.sgi.com/opengl/tips/rts/
- I think these techniques require GLUT, however, which isn't
- (currently) required by any other xscreensaver hacks.
-
* There should be strange lighting effects playing across the surface:
electric sparks, or little glittery blobs of light.
http://reality.sgi.com/opengl/tips/lensflare/ might provide guidance.
to use (or that look like they would take any less than several months
to become even marginally proficient with...)
- * Perhaps there should be a table top, on which it casts a shadow?
- And then multiple light sources (for multiple shadows)?
-
* Needs music. ("Hellraiser Themes" by Coil: TORSO CD161; also
