Okay, I have identified where the problem in my program is:
When I disable lighting my app works fine in 10.4.7 Intel or ppc.
When lighting is enabled the app only works fine in 10.4.7 ppc.
The initialization code for my NSOpenGLView is in the
initWithCoder: method
The code that I use to define lighting within this method is
something like:
self = [super initWithCoder:c];
NSOpenGLContext *glContext;
glContext = [self openGLContext];
[glContext makeCurrentContext];
// Lights
GLfloat ambientLight[] = {intAmbient,intAmbient,intAmbient,1.0};
GLfloat diffuseLight[] = {intDiffuse,intDiffuse,intDiffuse,1.0};
GLfloat specular [] = {intSpecular, intSpecular, intSpecular, 1.0};
GLfloat specref[] = {0.5, 0.5, 0.5, 1.0};
glEnable(GL_LIGHTING);
glLightfv(GL_LIGHT0, GL_AMBIENT,ambientLight);
glLightfv(GL_LIGHT0, GL_DIFFUSE,diffuseLight);
glLightfv(GL_LIGHT0, GL_SPECULAR, specular);
glEnable(GL_LIGHT0);
glEnable(GL_COLOR_MATERIAL);
glColorMaterial(GL_FRONT,GL_AMBIENT_AND_DIFFUSE);
glMaterialfv(GL_FRONT,GL_SPECULAR,specref);
glMateriali(GL_FRONT,GL_SHININESS,50);
// other stuff
return self;
As I said when I comment the glEnable (GL_LIGHTING) line, everything
works fine (except that there are no lights). When I comment the
glEnable(GL_COLOR_MATERIAL) line everything shows up well but only in
gray.
The strange thing is that my code works well in 10.4.7 ppc, but not
10.4.7 Intel.
I have installed the newest 10.4.7 Intel update:
SHA1MacOSXUpd10.4.7Intel.dmg= 10aa57dfccd63accb0939a894cea202a8910fb45
I appreciate any help
