Bei einem Projekt habe ich das Problem, dass ich bei der 3d Darstellung von Molekülen nicht die Moleküle sondern die Ansicht verändere, also bleibt der Winkel immer gleich!
Bei mir wird der Winkel aber immer wieder neu berechnet!!!
Bitte helft mir damit mein Arbeitgeber sitzt mir schon im Nacken !!!
Ich füge Euch hier den Ausschnitt der cpp Datei unten ein, und danach ddie Complette cpp File !!
Der Ausschnitt:
// berechnen des Winkels fuer gluPerspective
G = Mol->GreatestDist*1.3;
ViewD=2*G;
M = Mol->GetMolCenter();
D= sqrt((0-M[0])*(0-M[0])+(0-M[1])*(0-M[1])+(ViewD-M[2])*(ViewD-M[2]));
theta=atan(G/(2*D));
angle = (180 * 2 * theta / 3.14159);
GLdouble aspect = double(width)/double(height);
glViewport(0,0,width, height);
if(I<((G+D)*2)) I = (G+D)*2;
gluPerspective(angle,aspect,0.5,I);

Danke Bitte helft mir schnell, es müsste eigentlich schon gestern funktioniert haben !!!!
