Hi guys I'm stuck on a rotation problem, the thing is I'm building a 3d menu problem, since I'm using limbs I need to point them always to the camera, but since I can have X or Y angle rotations I can't seam to achieve a perfect solution. See the code below and the pic to see what I want..
#include "DarkGDK.h"
#define StartObj 4
#define EndObj 10
float getDist(float,float,float,float, float ,float);
void rotateOn(float,float,float);
void setupMenu(int,int,float,float,float);
int focusObj = 4;
float cameraX = 0.0f;
float camAngleX = 270.0f;
float camAngleY = 270.0f;
void DarkGDK ( void )
{
dbSetDisplayMode (1024,768,32);
dbSetWindowPosition(dbScreenWidth()/2-dbScreenWidth()/3,dbScreenHeight()/2-dbScreenHeight()/3);
dbAutoCamOff();
dbSetAmbientLight(50);
dbSyncOn();
dbSyncRate(60);
dbSetGlobalCollisionOff();
dbBackdropOn();
dbColorBackdrop(0);
//Mars
dbLoadImage("Teste\MarsTexture.jpg",1,1);
//Menu IMG
dbLoadImage("Teste\test.dds",3,1);

EDIT: I decide to change my aproach to the problem
