如何在JMonkeyEngine3中将相机投影到立方体上作为纹理? 你介意帮我吗?
我尝试通过这段代码来完成它,但它起作用了:
private void addCamera() {
Camera c = new Camera(100, 100);
c.setViewPort(0, 1, 0, 1);
c.setLocation(Vector3f.ZERO);
ViewPort v = new ViewPort("c", c);
v.attachScene(rootNode);
FrameBuffer fb = v.getOutputFrameBuffer();
fb.setDepthBuffer(Format.Depth);
Texture2D niftytex = new Texture2D(1024, 768, Format.RGB8);
fb.setColorTexture(niftytex);
Box b = new Box(Vector3f.ZERO, 1, 1, 1);
Geometry geom = new Geometry("Box", b);
Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
mat.setTexture("m_ColorMap", niftytex);
/**
* Here comes the texture!
*/
geom.setMaterial(mat);
localRootNode.attachChild(geom);
}

如果您使用TestRenderToTexture

示例,您将获得所需的内容。你可以把整个东西放在一个util类中,然后从你的项目中调用它(我自己也做过)。
