Ok, so if chunk is 16^3, and at xposition 4 ( 4 * 16 ), yposition 0, zposition 0 you pass in
cubeInFrustum(64, 0, 0, 16);

Thanks

Do you not need to get your cameras rotation?

Something along the lines of:

1  
2  
3  
4  
5  
6  
7  
8  
Vector3f pos = getYourCameraPosition();
double cameraPitchInRadians = Math.toRadians(YourCamerasPitch);
double cameraYawInRadians = Math.toRadians(YourCamerasYaw);
float newX = (float) Math.sin(cameraYawInRadians);
float newY = (float) Math.sin(cameraPitchInRadians);
glRotatef(newY-90f, 0.0f, 1.0f, 0.0f);
glTranslatef(x+.3f, y-0.3f, z-0.3f);
glRotatef(newX, 1.0f, 0.0f, 0.0f);


Of course, your rx and ry maybe the same as newX and newY above?!

Regards


Thanks so much steg90 I used the code that you provided and ended up adapting it a bit to get it to work with my engine and this was the final product I came to;

glLoadIdentity();
double cameraPitchInRadians = Math.toRadians(rY);
double cameraYawInRadians = Math.toRadians(rX);
float newX = (float) Math.sin(cameraYawInRadians);
float newY = (float) Math.sin(cameraPitchInRadians);
glRotatef(newX, 1.0f,0.0f, 0.0f);
glTranslatef(1.1f-0.8f,-1.1f,-1.3f);
glRotatef(newY-90.0f, 0.0f, 1.1f, 0.0f);
