The textures are automatically placed on the atlas map and the + * image data is stored in a byte array for each map name. Later each map can be retrieved as + * a Texture to be used further in materials.</p> + * + * <p>The first map name used is the "master map" that defines new locations on the atlas. Secondary + * textures (other map names) have to reference a texture of the master map to position the texture + * on the secondary map. This is necessary as the maps share texture coordinates and thus need to be + * placed at the same location on both maps.</p> + * + * <p>The helper methods that work with <code>Geometry</code> objects handle the <em>DiffuseMap</em> or <em>ColorMap</em> as the master map and + * additionally handle <em>NormalMap</em> and <em>SpecularMap</em> as secondary maps.</p> + * + * <p>The textures are referenced by their <b>asset key name</b> and for each texture the location + * inside the atlas is stored. A texture with an existing key name is never added more than once + * to the atlas. You can access the information for each texture or geometry texture via helper methods.</p> + * + * <p>The TextureAtlas also allows you to change the texture coordinates of a mesh or geometry + * to point at the new locations of its texture inside the atlas (if the texture exists inside the atlas).</p> + * + * <p>Note that models that use texture coordinates outside the 0-1 range (repeating/wrapping textures) + * will not work correctly as their new coordinates leak into other parts of the atlas and thus display + * other textures instead of repeating the texture.</p> + * + * <p>Also note that textures are not scaled and the atlas needs to be large enough to hold all textures. + * All methods that allow adding textures return false if the texture could not be added due to the + * atlas being full. Furthermore secondary textures (normal, spcular maps etc.) have to be the same size + * as the main (e.g. DiffuseMap) texture.</p> + * + * <p><b>Usage examples</b></p> + * Create one geometry out of several geometries that are loaded from a j3o file: + * <pre> + * Node scene = assetManager.loadModel("Scenes/MyScene.j3o"); + * Geometry geom = TextureAtlas.makeAtlasBatch(scene); + * rootNode.attachChild(geom); + * </pre> + * Create a texture atlas and change the texture coordinates of one geometry: + * <pre> + * Node scene = assetManager.loadModel("Scenes/MyScene.j3o"); + * //either auto-create from node: + * TextureAtlas atlas = TextureAtlas.createAtlas(scene); + * //or create manually by adding textures or geometries with textures + * TextureAtlas atlas = new TextureAtlas(1024,1024); + * atlas.addTexture(myTexture, "DiffuseMap"); + * atlas.addGeometry(myGeometry); + * //create material and set texture + * Material mat = new Material(mgr, "Common/MatDefs/Light/Lighting.j3md"); + * mat.setTexture("DiffuseMap", atlas.getAtlasTexture("DiffuseMap")); + * //change one geometry to use atlas, apply texture coordinates and replace material. + * Geometry geom = scene.getChild("MyGeometry"); + * atlas.applyCoords(geom); + * geom.setMaterial(mat); + * </pre> + * + * @author normenhansen, Lukasz Bruun - lukasz.dk + */ +public class TextureAtlas { + + private static final Logger logger = Logger.getLogger(TextureAtlas.class.getName()); + private Map<String, byte[]> images; + private int atlasWidth, atlasHeight; + private Format format = Format.ABGR8; + private Node root; + private Map<String, TextureAtlasTile> locationMap; + private Map<String, String> mapNameMap; + private String rootMapName; + + public TextureAtlas(int width, int height) { + this.atlasWidth = width; + this.atlasHeight = height; + root = new Node(0, 0, width, height); + locationMap = new TreeMap<String, TextureAtlasTile>(); + mapNameMap = new HashMap<String, String>(); + } + + /** + * Add a geometries DiffuseMap (or ColorMap), NormalMap and SpecularMap to the atlas. + * @param geometry + * @return false if the atlas is full. + */ + public boolean addGeometry(Geometry geometry) { + Texture diffuse = getMaterialTexture(geometry, "DiffuseMap"); + Texture normal = getMaterialTexture(geometry, "NormalMap"); + Texture specular = getMaterialTexture(geometry, "SpecularMap"); + if (diffuse == null) { + diffuse = getMaterialTexture(geometry, "ColorMap"); + + } + if (diffuse != null && diffuse.getKey() != null) { + String keyName = diffuse.getKey().toString(); + if (!addTexture(diffuse, "DiffuseMap")) { + return false; + } else { + if (normal != null && normal.getKey() != null) { + addTexture(diffuse, "NormalMap", keyName); + } + if (specular != null && specular.getKey() != null) { + addTexture(specular, "SpecularMap", keyName); + } + } + return true; + } + return true; + } + + /** + * Add a texture for a specific map name + * @param texture A texture to add to the atlas. + * @param mapName A freely chosen map name that can be later retrieved as a Texture.
