使用libgdx渲染的3d对象没有使用Blender创建时使用的颜色 [英] Rendered 3d object using libgdx does not have colors as used to create using blender

问题描述

我已经使用搅拌器创建了3d对象.然后将其导出为g3db和gsdj类型，并与libgdx一起使用.一切正常，但对象的颜色未按预期呈现.

I have created a 3d object using a blender. and I exported it as a g3db and gsdj types and used with libgdx. everything works fine but the colors of the object are not rendering as expected.

我尝试使用各种方法来创建对象并使用搅拌器导出.过去，我尝试使用libgdx-fbx-conv将fbx转换为g3db.并且它也不起作用.

I tried using various ways to create an object and exporting with a blender. and In the past, I’ve tried libgdx-fbx-conv to convert fbx to g3db. and its also not working.

public class experiments extends ApplicationAdapter {

    private ModelBatch modelBatch;
    private Environment environment;
    private PerspectiveCamera cam;
    private Model model;
    private ModelInstance instance;
    private CameraInputController camController;

    @Override
    public void create() {
        modelBatch = new ModelBatch();
        environment = new Environment();
        environment.set(new ColorAttribute(ColorAttribute.AmbientLight, 0.4f, 0.4f, 0.4f, 1f));
        float color = 0.0001f;
        environment.add(new DirectionalLight().set(color, color, color, -1f, -0.8f, -0.2f));

        cam = new PerspectiveCamera(67, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
        cam.position.set(3f, 3f, 3f);
        cam.lookAt(0, 0, 0);
        cam.near = 1f;
        cam.far = 300f;
        cam.update();

        G3dModelLoader loader = new G3dModelLoader(new UBJsonReader());
        model = loader.loadModel(Gdx.files.internal("test.g3db"));
        instance = new ModelInstance(model);

        camController = new CameraInputController(cam);
        Gdx.input.setInputProcessor(camController);
    }

    @Override
    public void render() {
        camController.update();

        Gdx.gl.glViewport(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT);

        modelBatch.begin(cam);
        modelBatch.render(instance, environment);
        modelBatch.end();
    }

    @Override
    public void dispose() {
    }
}

推荐答案

这很可能与呈现方式有关.Blender使用Cycles或Eevee(使用Belender 2.8)进行渲染，而LibGDX使用OpenGl.就像您用两个不同的相机拍摄同一物体的照片一样.

That has most likely just something to do with the way it is being rendered. Blender renders it with either Cycles or Eevee (with Belender 2.8), while LibGDX uses OpenGl. It's like you make a photograph of the same object with two different cameras.
