我正在网上冲浪,寻找在Android上翻页的良好效果,但似乎没有。由于我正在学习平台,因此能够做到这一点似乎很不错。我设法在这里找到一个页面:http : //wdnuon.blogspot.com/2010/05/implementing-ibooks-page-curling-using.html- (void)deform{ Vertex2f vi; // Current input vertex Vertex3f v1; // First stage of the deformation Vertex3f *vo; // Pointer to the finished vertexCGFloat R, r, beta; for (ushort ii = 0; ii < numVertices_; ii++) { // Get the current input vertex. vi = inputMesh_[ii]; // Radius of the circle circumscribed by vertex (vi.x, vi.y) around A on the x-y plane R = sqrt(vi.x * vi.x + pow(vi.y - A, 2)); // Now get the radius of the cone cross section intersected by our vertex in 3D space. r = R * sin(theta); // Angle subtended by arc |ST| on the cone cross section. beta = asin(vi.x / R) / sin(theta); // *** MAGIC!!! ***v1.x = r * sin(beta);v1.y = R + A - r * (1 - cos(beta)) * sin(theta); v1.z = r * (1 - cos(beta)) * cos(theta);// Apply a basic rotation transform around the y axis to rotate the curled page. // These two steps could be combined through simple substitution, but are left // separate to keep the math simple for debugging and illustrative purposes. vo = &outputMesh_[ii]; vo->x = (v1.x * cos(rho) - v1.z * sin(rho)); vo->y = v1.y; vo->z = (v1.x * sin(rho) + v1.z * cos(rho)); } }给出了iPhone的示例代码(上面),但是我不知道如何在android上实现它。那里的任何数学神都可以帮助我解决如何在Android Java中实现这一点。是否可以使用本机的绘图API,我是否必须使用openGL?我可以以某种方式模仿行为吗?任何帮助,将不胜感激。谢谢。
