CATSurParam* pSurParm = new CATSurParam();
pSurface ->GetParam( mathPoint, *pSurParm);
double U = pSurParm ->GetParamU;
double V = pSurParm ->GetParamV;作者: kingbaby123 时间: 2006-7-7 23:59
对于 pSurface ->GetParam( mathPoint, *pSurParm) 有个问题
请注意:
This transformation is only available on canonical objects such as planes, cylinders, cones. If the surface is not canonical, use a projection operator.
所以,If the surface is not canonical,我们该怎么做?
