<p>Description: Test points on a bezier curve to see if they are near the plane. Parameters: bezcrv - [in] s0 - [in] s1 - [in] the interval from s0 to s1 is tested (s0 &lt; s1) sample_count - [in] number of interior points to test. Numbers like 1, 3, 7, 15, ... work best. endpoint_tolerance - [in] If &gt;= 0, then the end points are tested to see if the distance from the endpoints is &lt;= endpoint_tolerance. interior_tolerance - [in] (&gt;=0 and &gt;=endpoint_tolerance) This tolerance is used to test the interior sample points. smin - [put] If not nullptr, *smin = bezier parameter of nearest test point. smax - [put] If not nullptr, *smax = bezier parameter of farthest test point. If false is returned, this is the parameter of the test point that failed. Returns: True if all the tested points passed the tolerance test. False if at least one tested point failed the tolerance test. (The test terminates when the first failure is encountered.) </p>

<p>Description: Evaluate the plane at a list of point values. Parameters: Pcount - [in] number of points P - [in] points value - [in] If not null, value[] must be an array of length at least Pcount. The values will be stored in this array. If null, the an array will be allocated with onmalloc() and returned. value_range - [out] If not null, the range of values will be returned here. Returns: An array of Pcount values. If the input parameter value was null, then the array is allocated on the heap using onmalloc() and the caller is responsible for calling onfree() when finished. If the input is not valid, null is returned. </p>
