OpenGl Unit zum einfachen körper zeichnen

seawolf · Beiträge: 20 WinXP SP1 Delphi 6/7

Hi diese Unit (koerper_draw.pas) hab ich aus Langerweile in der Berufsschule geschrieben und weil mir des Körper zeichnen zu umständlich war.

In dieser unit verwende ich den DGLOpenGl Header welchen ihr unter www.delphigl.com saugen könnt.
Sollte der Header gegebenenfalls nicht mehr funktionieren (z.B.: durch Aktualisierung) kann ich euch auch gern die Version des Headers schicken die ich jetzt verwende.

die Proceduren zum erstellen der Körper sind alle in der Klasse "koerper" unter gebracht.

Die Variablen "height", "width", "deep" sidn für "Höhe", "Breite", "Länge" (z-Achse) des Körpers.
Die Variable "diffi" (kommt z.b. beim Trapez vor) bestimmt das einrücken mancher punkte.
Diese Variablen sind single Werte und werden in OpenGl Standart angegeben.

eckpunkte eines quadrates x,y,z: (0,0,0); (0.5,0,0); (0.5,0.5,0); (0,0.5,0);

parallelogram mit selbigen punkten + "diffi" (0,0,0); (0.5,0,0); (0.5,0.5,0); (0,0.5,0); (0.2);
das parallelogramm wird nun an folgenden koordinaten gezeichnet:
(0,0,0); (0.5,0,0); (0.3,0.5,0); (-0.2,0.5,0);

kurze Übersicht der Körper die ihr damit einfach zeichnen könnt:

Würfel
Quader
Pyramide
Pyramidenstumpf
Trapez-Körper
Parallelogramm-Körper

Kugel
Kegel
Zylinder

ihr könnt auch Flächen zeichnen...

Quadrat
Rechteck
Dreieck
Trapez
Parallelogramm

mit Kommentaren bin ich noch relativ unbeholfen, daher ist sie wahrscheinlich eher schlecht als recht kommentiert.
Ich arbeite weiter und versuche noch andere Körper hinzuzufügen.

Über euer feedback würdsch mich sehr freuen

So eine Woche ists nun her ^^

Hab kaum noch Ideen für neue Körper, welche fallen euch noch ein?
Will die Unit später ma für son kleines Game verwenden fällt euch noch was ein um die Performance zu verbessern?
Da berechnungen allgemein sehr Rechenaufwendig sind sollt ich die besser in ner extra Procedure auslagern un dann irgendwie die errechneten Werte in nen dyn Array schreiben?

Für alle die sich die Unit nicht loaden wollen hier gleich ma der code:

Hallo seawolf,

der Code sieht ja erst mal sehr verheißungsvoll aus.
Könntest Du evtl. mal ein kleines Demoprojekt (Quelltext) mit anhängen, damit man gleich mal richtig "loslegen" kann, ohne sich groß einzuarbeiten?

schön wäre es, wenn du noch die normalen berechnen und an opengl übergeben würdest

positionen wären auch was nettes, dann erspart man sich die ganzen pushes und pops sowie das ganze translate und wenn du da schon bei bist kannst du auch rotationen mit rein nehmen

und die quadrics die du für zylinder und kugeln brauchst kannst du auch direkt im code erstellen, das ist irgendwie komfortabler:

Hi

hier erstma der Code wo man sich die variable Diffi genauer anschauen kann ;-)

habe noch 2 neue texturen hinzu genommen derr rets entspricht dem vorherigen code. Datei siehe Anhang.

@F34rofTh3D4rk: das mit den Positionen und der Rotation is ne Supa Idee danke werd ich morgen mal einbauen :-D

, was die Normalen angeht so weis ich nicht wirklich wie man die berechnet. Hatte die mir ma vor einiger Zeit angesehn aber habs nich vertsanden und immo wegen weniger zeit schleifen lassen :-(

. kannst du mir erklären wofür die gebraucht werden und wie die Berechnung genau funktioniert? Danke.

mach doch statt deinen ganzen flächen ein objekt mit vier ecken oder gleich ein polygon dass mittels TriangleFan oder strip oder wie auch immer gezeichnet wird, weil ich glaube net, dass jemand solche funktionen wie für das trapez gut gebrauchen kann.

du kannst noch diverse nurbs einbauen, dazu zähle ich auch rotationskörper über eine funktion.
