Lighting and Appearance I. Palmer, Essential Java 3D fast © Springer-Verlag London Limited 2001 Essential Java 3D fast Introduction To actually see the objects in the scene we need a light source. Up to now we've either ignored this fact or have included simple lights just to allow us to see the shape of the objects that we have created. Weare now going to look at how we can define lights and materials to give the objects in the scene a more realistic appearance. We'll start by looking at the way the lighting model works in Java 3D, which like the other features we've looked at so far doesn't stray very far from that used in other existing graphics systems.

This texture is a little large for the face; we would like the bricks to appear smaller. We can do this by changing the texture coordinates. If we want the texture to be tiled twice in each direction, resulting in four copies of the texture image to be applied to the face, we merely change the texture coodinates so that they will be larger than the actual image. 0f. 0f. l,2,3,3,O,l,2,l,2,3,O,l ,2,3,O,3,O,l ,2,l,2,3,O}; If we change these lines and recompile and run the program we get the output shown in Plate 14.
