摘要： A method and apparatus utilizes a three dimensional rendering engine to rotate an image based on user selected or otherwise determined screen orientation. A vertex coordinate transformation is defined for a rotated destination image. The source image is used as a texture for texture mapping during rendering operation to produce rotated image. In one embodiment, a separate set of software instructions is used for each orientation mode. Accordingly, a non-pixel by pixel based 3D rotation may be carried out using a 3D rendering engine to avoid a single parameter based seriatim pixel by pixel based orientation.
摘要翻译： 一种方法和装置利用三维渲染引擎来基于用户选择或以其他方式确定的屏幕取向旋转图像。 为旋转的目标图像定义顶点坐标变换。 源图像在渲染操作期间用作纹理映射的纹理以产生旋转图像。 在一个实施例中，对于每个定向模式使用单独的一组软件指令。 因此，可以使用3D渲染引擎来执行基于像素的基于3D的3D旋转，以避免基于逐个像素的基于单个参数的基于像素的取向。
