电源微型 USB 连接器旁边是微型 USB 端口。要在 Zero 上使用大多数外设,您需要购买微型转标准 USB 集线器。确保你得到一个不需要外部电源的,除非你打算使用像网络摄像头这样的耗电设备。在这种情况下,你需要一个有电源的集线器,因为零线不能提供太多的电流。

将 M 矩阵转置,然后压平并输入 glLoadMatrixf() 函数。 在图像中放置虚拟物体 我们需要做的第一件事是将图像(打算放置虚拟物体的图像)作为背景添加进来。在 OpenGL 中,该操作可以通过创建一个四边形的方式来完成,该四边形为整个视图。完成该操作最简单的方式是绘制出四边形,同时将投影和模拟试图矩阵重置,使得每...
