NX二次开发-射线交点

函数：UF_MODL_trace_a_ray()

函数说明：打射线，找交点。

用法：

#include "Text.h"

#include <stdio.h>
#include <uf.h>
#include <uf_part.h>
#include <uf_defs.h>
#include <uf_modl.h>
void ufusr(char *param, int *retcode, int param_len)
{
    UF_initialize();
    tag_t tagBody[2] = { 45071,138371};
    double douPoint[3] = { 0.0,0.0,0.0 };
    double douRaydir[3] = { 0.0,1.0,0.5 };
    double transform[16] = { 1.0,0.0,0.0,0.0,0.0,1.0,0.0,0.0,0.0,0.0,1.0,0.0,0.0,0.0,0.0,1.0 };
    int     hits_found;
    UF_MODL_ray_hit_point_info_p_t  hit_list;
    UF_MODL_trace_a_ray(2, tagBody, douPoint, douRaydir, transform, 0, &hits_found, &hit_list);
    for (int i = 0; i < hits_found; i++)
    {
        tag_t tagPoint;
        UF_CURVE_create_point(hit_list[i].hit_point, &tagPoint);
    }
    UF_terminate();
}

int ufusr_ask_unload(void)
{
    return (UF_UNLOAD_IMMEDIATELY);
}

效果：
