Hi,  I'm trying to use a display list to draw a set of axes in 3D, the code for the display list is below, but for some reason the colors aren't showing up (everything is gray) - I needed the x, y, and z axes to be red, green, and blue respectively.  Any ideas as to why these colors aren't rendering?

Thanks!

1. void createAxesList(){
2. if(!(boolean)gl.glIsEnabled(gl.GL_NORMALIZE)) gl.glEnable(gl.GL_NORMALIZE){
3.       axesList = gl.glGenLists(1);
4.        gl.glNewList(axesList, gl.GL_COMPILE);
   
    
      //x axis
     gl.glColor3f(1.0f, 0.0f, 0.0f);
     gl.glBegin(gl.GL_LINES);
     gl.glVertex3f(0.0f, 0.0f, 0.0f);
     gl.glVertex3f(80.0f, 0.0f, 0.0f);
     gl.glEnd();
5. 
     //y axis
     gl.glColor3f(0.0f, 1.0f, 0.0f);
     gl.glBegin(gl.GL_LINES);
     gl.glVertex3f(0.0f, 0.0f, 0.0f);
     gl.glVertex3f(0.0f, 80.0f, 0.0f);
     gl.glEnd();
6. 
     //z axis
      gl.glColor3f(0.0f, 0.0f, 1.0f);
     gl.glBegin(gl.GL_LINES);
     gl.glVertex3f(0.0f, 0.0f, 0.0f);
     gl.glVertex3f(0.0f, 0.0f,80.0f);
     gl.glEnd();
    
     gl.glEndList();
   
   }
   

Hi everyone,

I'm working on a project using the anar library where we're transforming 3D objects (like translating, rotating, etc).  We then need to shift the frame of reference of the 3D environment so that it's aligned with the object.  For example:  we draw a box and then shift it 30 units along the x axis and then rotate it 30 degrees.  We need to then change the coordinate system so that it's shifted over and rotated exactly the same way the object is.

Is there any way to do this in anar?  We'd appreciate the help.

Thanks!
