accessin gl class from inside a subclass
Jul 11th, 2009, 1:44am  
Hi ive made a program and im using the opengl comnamd from the openglapi, using import javax.media.opengl.GL; and glgraphics

for accessing to the opengl commands i need to do :  
GLGraphics renderer = (GLGraphics)g;
 GL gl = renderer.beginGL(); in then i can acces to the opengl commands in this way:   gl.glRotatef(144 * - 0.1, 0, 0, 0.5);

this works if when im in the main draw but what about if a wanna access to the gl commands from inside a class?

if i try  gl.glRotatef(233, 1, 0, 1); inside a function of a class i get : "canot find anything named "gl", ive also tried "name_of_my_app".this.gl. gl.glRotatef(144 * - 0.1, 0, 0, 0.5);

any idea of how can i do this?


thanks


pun.

Just declare gl at the top of your sketch.

hi, if i declare gl at the top of my sketch the app runs without erros ,  but the "gl.glTranslatef(13,2, 0); "  i have inside the class doesnt affect each object individually  , in other words they do nothing.

Any idea of why is this?


thanks

Sounds like there may be some other errors in your code. The GL commands wouldn't just do nothing without errors. Can you post some code? Maybe the class function you're talking about?
