That’s right, throw glColor3f away.
It is designed as the primary widget for JOGL applications. A sphere is actually drawn using a lot of quads “rectangle floating in space”. Having a triangle is nice and all and this is actually the basis of almost all games out therebut how about some more sophisticated shapes?
For your convenience, the important classes so far are summarised in the following figure: The init runs only once. Recall that an applet extends javax. I shall discuss NEWT later. Nehe production maintains an excellent Kogl Tutorials http: Ignoring the displayChanged method, we come to the last and most important one: In the next three lines, we bind these parameters to a specific light, namely LIGHT1by specifying the parameter to set, the appropriate array, and an index where to start in this array this could be different from 0 if you use one giant array for performance reasons.
You should see something like in the next figure:. This also demonstrates nicely how to use multiple textures. Choose the appropriate JOGL version that you used to compile your application, e. Navigation menu Personal tools Log in. From now an, everything will be lighted.

In effort to employe good design patterns and code reuse, we will create a new class called JoglEventListener which implements all of the methods required for the four set of events we’ve subscribed to. After all, we specified only a blue tuotrial, and no lights or shadows, so where should the “3D effect” come from?
This would be called in a multiple screen scenario. A circle around the z axis, computed with sin und cos from the standard Java libraries.
We tktorial gluSphere with the quadric identifier, radius, and slices and stacks think “longitude and latitude detail along z-axis”. You will notice that although the 3D coordinates are evenly spaced, the triangle on screen is not. A 3D coordinate0, 0 slightly to the left, with a fourth element set to 1. For a start, we set the camera position at 0, 0,which is units just in front of the screen where you are probably sitting. The sphere looks kind of flat, but that is ok: After you confirm that you accept the license agreement for JDKyou can select which version jol Java you need, for this tutorial I will use Java SE 8 64 bits for Windows you can follow along on OS X, the procedure is essentially the same: So now we have the basics of triangles, bodies, light and material, and texture.
Tutoriial you are unfamiliar with java.

GLEventListener ; 5 import com. Once again, we go into the display method and set everything:. I used GIMP and a scanned foto to produce a solar panel texture with font on it.
The OpenGL mother site is at http: The light source from the left illuminates the left side of the sphere with tutoriao 0.

This allows computer graphics programmers to use the object-oriented tools for Java with hardware-accellerated 2D and 3D graphics while leveraging their existing knowledge of OpenGL.

Second, just before drawing the sphere, we have to tell JOGL that the next thing coming should use the texture “bind the texture to the GL context”.
