TODO: * The "gold" color isn't quite right; it looks more like "yellow" than "gold" to me. * For some reason, the interior surfaces are shinier than the exterior surfaces. I don't understand why, but this should be remedied. * Perhaps use a slightly-bumpy or oily 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. * 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 supports Gouraud shading (interpolating edge normals from face normals, 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. * Need to add some more modes, to effect the transition from the cube shapes to the "spike" or "leviathan" shapes. I have extensive notes on how these transformations occur, but unfortunately, due to camera trickery, the transitions require dematerializations which do not preserve object volume. But I suppose that's allowed, in non-Euclidian or hyperdimensional spaces (since the extra mass could simply be rotated along the axis to which one cannot point.) The other hard thing about this is that the "leviathan" shapes contain a much larger number of facets, and I modelled this whole thing by hand, since I don't have any 3d-object-editing tools that I know how 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 duplicated on the "Unnatural History 2" compilation, WORLN M04699.) * I'm not totally happy with the spinning motion; I like the acceleration and deceleration, but it often feels like it's going too fast, or not naturally enough, or something. * However, the motion is better than that used by gears, superquadrics, etc.; so maybe I should make them all share the same motion code. * E.Lassauge - 28-Nov-2000: modified release part to add freeing of GL objects * E.Lassauge - 21-Nov-2000: use new common xpm_to_ximage function */ #ifdef VMS #include "vms_x_fix.h" #endif #include #ifdef STANDALONE #define PROGCLASS "Lament" #define HACK_INIT init_lament #define HACK_DRAW draw_lament #define lament_opts xlockmore_opts #define DEFAULTS "*delay: 10000 \n" \ "*wireframe: False \n" \ "*texture: True \n" #include "xlockmore.h" #else /* !STANDALONE */ #include "xlock.h" /* from the xlockmore distribution */ #include "vis.h" #endif /* !STANDALONE */ #ifdef MODE_lament #undef countof #define countof(x) ((int)(sizeof((x))/sizeof((*x)))) #define DEF_TEXTURE "True" static Bool do_texture; static XrmOptionDescRec opts[] = { {(char *) "-texture", (char *) ".lament.texture", XrmoptionNoArg, (caddr_t) "on"}, {(char *) "+texture", (char *) ".lament.texture", XrmoptionNoArg, (caddr_t) "off"}, }; static argtype vars[] = { {(caddr_t *) & do_texture, (char *) "texture", (char *) "Texture", (char *) DEF_TEXTURE, t_Bool}, }; static OptionStruct desc[] = { {(char *) "-/+texture", (char *) "turn on/off texturing"} }; ModeSpecOpt lament_opts = {sizeof opts / sizeof opts[0], opts, sizeof vars / sizeof vars[0], vars, desc}; #ifdef USE_MODULES ModStruct lament_description = {"lament", "init_lament", "draw_lament", "release_lament", "draw_lament", "change_lament", NULL, &lament_opts, 10000, 1, 1, 1, 64, 1.0, "", "Shows Lemarchand's Box", 0, NULL}; #endif #include "xpm-ximage.h" #ifdef STANDALONE #include "../images/lament.xpm" #else #include "pixmaps/lament.xpm" #endif #define RANDSIGN() ((LRAND() & 1) ?
