如何将纹理分配给 java3d 中加载的 OBJ 文件

我有一个 java 3d 应用程序，该应用程序将 OBJ 文件加载到我的场景中。如何为该模型分配纹理（jpg 文件）？更准确地说，当我想将纹理分配给原始 java 对象（例如球体）时，我使用以下方法：

Sphere sphere = new Sphere(Radius, Primflags, Appearance);

但是，在加载和添加 obj 文件时，我这样做：

Scene scene = getSceneFromFile("OBJ file");
myBranchGroup = scene.getSceneGroup();

在第二种情况下，我找不到分配纹理的方法质地。我该怎么做呢？

原文

I have a java 3d application and this application I load an OBJ file into my scene. How can I assign a texture (a jpg file) to this model?
To be more precise, when I want to assign texture to a primitive java object (e.g. sphere) I use the following:

Sphere sphere = new Sphere(Radius, Primflags, Appearance);

However, when loading and adding an obj file I do:

Scene scene = getSceneFromFile("OBJ file");
myBranchGroup = scene.getSceneGroup();

And in second case, I can find no way of assigning the texture. How should I do that?

您必须使用制作 obj 文件的程序或者可以加载该文件。绘制它，然后导出该文件。然后在任何方法之外添加此代码

static TextureLoader loader = new TextureLoader("C:\\Users\\Sawyera\\Desktop\\Paint Layer 1.jpg",
"RGP", new Container());
static Texture texture = loader.getTexture();

然后

texture.setBoundaryModeS(Texture.WRAP);
texture.setBoundaryModeT(Texture.WRAP);
texture.setBoundaryColor(new Color4f(0.0f, 1.0f, 0.0f, 0.0f));
TextureAttributes texAttr = new TextureAttributes();
texAttr.setTextureMode(TextureAttributes.MODULATE);
Appearance ap = new Appearance();
ap.setTexture(texture);
ap.setTextureAttributes(texAttr);
 int primflags = Primitive.GENERATE_NORMALS
    + Primitive.GENERATE_TEXTURE_COORDS;
    ObjectFile loader = new ObjectFile(ObjectFile.RESIZE);

然后在将模型分配到场景之前添加此代码。假设 3D 模型变量称为 model

model.setAppearance(ap);

You would have to use a program that you made the obj file or were you can load the file. Paint it, then export that file. Then add this code to it outside any methods

static TextureLoader loader = new TextureLoader("C:\\Users\\Sawyera\\Desktop\\Paint Layer 1.jpg",
"RGP", new Container());
static Texture texture = loader.getTexture();

Then

texture.setBoundaryModeS(Texture.WRAP);
texture.setBoundaryModeT(Texture.WRAP);
texture.setBoundaryColor(new Color4f(0.0f, 1.0f, 0.0f, 0.0f));
TextureAttributes texAttr = new TextureAttributes();
texAttr.setTextureMode(TextureAttributes.MODULATE);
Appearance ap = new Appearance();
ap.setTexture(texture);
ap.setTextureAttributes(texAttr);
 int primflags = Primitive.GENERATE_NORMALS
    + Primitive.GENERATE_TEXTURE_COORDS;
    ObjectFile loader = new ObjectFile(ObjectFile.RESIZE);

Then add this before you assign the model to the scene. Assuming the 3D model varrible is called model
