Question

我正在使用Vuforia SDK开发用于增强现实的android应用程序。 Vuforia使用茶壶模型作为样本。我想用不同的3D模型进行更改。

首先，我读了here，但不明白如何更改它。

我将某些模型下载为.obj并用记事本打开。我可以到达模型的顶点。例如，

v -47.434967 -14.179193 41.621128
v -47.290016 -32.284641 30.312384
v -50.046577 -28.483284 28.886757
v -48.418915 -26.21903 33.460499
v -46.001163 -30.491556 33.941067
v -56.681168 -27.034826 15.786369
v -56.716259 -23.535177 19.358313
v -54.001244 -27.203417 22.164679
v -54.523552 -29.940945 18.01193

vt 0.162396 0.657685 0
vt 0.693161 0.224146 0
vt 0.926491 0.934053 0
vt 0.587396 0.694719 0
vt 0.312997 0.011653 0
vt 0.493802 0.29425 0
vt 0.571748 0.898927 0
vt 0.524454 0.694721 0
vt 0.919639 0.171535 0
vt 0.375939 0.011657 0

在Vuforia样本中，有一个称为“茶壶”的类，它具有一些获取模型顶点的方法。

        mIndBuff = fillBuffer(TEAPOT_INDICES);
        indicesNumber = TEAPOT_INDICES.length;
    }

我的大脑非常盲目，我真的不知道该怎么做。

你能帮我吗？

谢谢
