well i read this source code that had the lighting done pretty good
but it was kind of hard to understand ( not the lighting part, but everything else )
so I wrote my own program but using the lighting part of the source code, and........my lighting doesnt work.
this is my class code for the geometry + lighting part

gf.setTextureCoordinateParams(1,2);
gf.setTextureCoordinates(0,txt);
gf.setStripCounts(strips);
gf.setCoordinates(pts);
gf.setContourCounts(contours);
NormalGenerator ng = new NormalGenerator();
ng.setCreaseAngle ((float) Math.toRadians(30));
ng.generateNormals(gf);
Appearance app = new Appearance();
Material mat = new Material();
mat.setShininess(0.01f);
mat.setEmissiveColor(0.0f, 0.0f, 0.0f);
mat.setAmbientColor(0.1f, 0.1f, 0.1f);
app.setMaterial(mat);
try{
TextureLoader txtLoader = new TextureLoader(new java.net.URL(texture),null);
Texture2D textImg = (Texture2D) txtLoader.getTexture();
TextureAttributes texatt=new TextureAttributes(TextureAttributes.BLEND, new Transform3D(), new Color4f(1.0f, 1.0f, 1.0f, 1.0f), TextureAttributes.NICEST);
app.setTextureAttributes(texatt);
app.setTexture(textImg);
}catch(java.net.MalformedURLException e){
System.out.println("he");
}
setGeometry(gf.getGeometryArray());
setAppearance(app); |
and this is the tester class that I use for both the other source code and my code.
