Method Summary

Modifier and Type	Method and Description
java.nio.FloatBuffer	convertPositionBuffer(int dstWidth, int dstHeight, int srcWidth, int srcHeight) 外设是竖屏时顶点坐标换算，以免绘制变形
java.nio.FloatBuffer	convertTextureBuffer(int dw, int dh, int sw, int sh)
java.nio.FloatBuffer	getDefaultTextureBuffer()
java.nio.FloatBuffer	getDefaultVertexBuffer()
java.nio.FloatBuffer	getPositionBuffer(boolean flip) 传进来的坐标范围是0-1.0f,需要转换为顶点坐标 顶点坐标系，往右是x轴这个方向；往Y是Y轴正方向
