Accordingly, if you want to map the lower left corner (-1, -1) of the cube's front face to the texture's lower left corner, you must assign the texture coordinates (0, 1) to vertex 0.
相应地，如果您需要将立方体正面的左下角映射到纹理的左下角，必须将纹理坐标(0,1)指派给顶点0。
WKT uses the lower left corner for (0, 0) and all positive X and Y coordinates are to the right and upwards, respectively.
WKT 定义左下角为(0, 0)，所有为正的 X 和 Y 坐标都在这个点的右边和上边。
Therefore, Flex picks up the local coordinates of a point near the bottom right corner of the component in question and applies "local to global" conversions to it.
因此，Flex挑选对应组件的右下角附近的点的局部坐标，然后对其应用“局部到全局”的转换。
