3-Dimensionale Darstellung von Matrizen

[snuuts]

habe mal ein wenig nach einem bild gegoogelt das in etwa das beschreibt was ich
brauche:

http://www.an.psu.edu/ojj/courses/cpp-lang/cpp-images/3d-array.gif

wenn man die kästchen durch die zahlen erstetzt die ich darstellen will (sprich die werte die im array stehen), dann ist das eigentlich alles was ich brauche. Muss ich dafür echt das volle programm der grafikprogrammierung durchlaufen ?

edit: danke gregor. werds mir mal anschauen...

Ach, sowas willst Du nur? Und Du hast auch nur so kleine Arrays? Dann ist Volume-Rendering natürlich Overkill. ...bei sowas, was Du da hast, kann ich Dir leider nicht weiterhelfen. Scheint aber auch nicht besonders aufwändig zu sein, das kurz selbst zu schreiben.

[Vertexwahn]

auf welchem Betriebssystem soll das laufen? nur Windows?
wie groß sind die Zahlen in dem Array - also wieiviel stellen werden sie haben? 1000 Stellen? weniger als 20 Stellen?
wie groß ist maximal das Array? 1000*1000*1000? kleiner?
für was brauchst du das genau?

[snuuts]

optimal wäre , wenns BS-unabhängig ist, aber wenn´s nur unter windows läuft ist es auch ok. die dimension des arrays wird nicht über 20x20x20 hinausgehen und die werte in dem Array sind auch maximal zweistellig.

[TheTester]

Probiers mal mit Mathematica oder Maple, wenn du den Arrayindex als Koordinate nimmst dann solltest du da die Werte zumindest als Punkte in einem 3D Koordinatensystem darstellen können. Beide Programme sollten das dann sogar als C Code exportieren können.

hmmm...danke, wäre vielleicht ein ansatz aber ich muss leider die werte ausgeben
und nicht nur punkte. Habe im moment leider weder Maple noch Mathematica aber werd´s die tage mal in der uni versuchen...

[Vertexwahn]

ach programmiers doch selber - ist doch mit opengl kein Problem:
benutz einfach als Grundlage:
http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=14

Die paar Zahlen noch richtitg ausrichten und fertig

wow, sieht gut aus. werd´s versuchen. danke!

so hab mal einen Würfel mit Zahlen gemacht:
