1、Y轴因子 sphereFactorY = 1.0f/cosf(halfFieldOfViewRad); 2、X轴因子 const GLfloat angleX = atanf(frustumPtr...->tangentOfHalfFieldOfView * aspectRatio); frustumPtr->sphereFactorX = 1.0f/cosf(angleX); 扩展 场景图(

不难看出,这里使用了C++中的cmath库,因此其中的sinf、cosf和sqrtf都来自这个库。 ? ?

笔者视其默认安装了腾讯云其他服务(DNS, COSF 和 CDN)插件(其实与专享版和普通版也就这点区别),更适合新手用户,故作此文。
CVM 上挂载CFS、COSF,然后通过CFS Filetruck 迁移备份工具,将CFS路径下文件迁移至本地COSFS路径,然后通过COSFS上传。
