利用的是函数UF_CURVE_create_ocf_feature();
函数里面的参数有一个是表示偏置曲线的tag_t类型的参数,还有一个是表示曲面的tag_t类型的参数,但是我将曲线曲面的ID带入,怎么都得不到正确的结果。后来在文档中发现表示偏置曲线tag_t类型的参数必须是一个string,而曲面必须是一个face collector。那么如何将曲线的ID转化为string,还有如何将曲面的ID转化为face collector?
谢谢指导!!!!
代码如下(insect_curve 表示需要偏置曲线的ID,FP_surface表示曲面):
UF_CURVE_ocf_data_p_t offset_data ;
offset_data =(UF_CURVE_ocf_data_s*)malloc(sizeof(UF_CURVE_ocf_data_s));
memset(offset_data,0,sizeof(UF_CURVE_ocf_data_s));

real_string_data->string_tag=insect_curve; // (有问题)
