Re: [gl4java-usergroup] Linux & Display Lists

[Jean-Yves B. <jea...@wa...>]

Hello,

Be carefull:
parameter of glGenLists(param) is the number of display list you want to create.
The return value is an id used to call and delete the display list.
In you code, it seems to be the same parameter.

I think this code would be better:

                nName = gl.glGenLists (1);          // generate one new list
                gl.glNewList (nName, gl.GL_COMPILE);    // start of display list definition

                ...<opengl calls>...                            // I'm currently just using lines & quads

                gl.glEnd();                                             // end of display list definition

                ...

                gl.glCallList (nName);                          // draw display list


I can't say about linux, but on macintosh and windows (as you said), it runs very well.

regards.

Jean-Yves.
