TIntrTriangle3Triangle3

Compute intersection between 3D triangles use [Test()](API\Plugins\GeometricObjects\Intersection\TIntrTriangle3Triangle3\Test) for fast boolean query, does not compute intersection info use [Find()](API\Plugins\GeometricObjects\Intersection\TIntrTriangle3Triangle3\Find) to compute full information By default fully-contained co-planar triangles are not reported as intersecting.

Syntax

template<typename Real>
class TIntrTriangle3Triangle3

Remarks

Compute intersection between 3D triangles use Test() for fast boolean query, does not compute intersection info use Find() to compute full information By default fully-contained co-planar triangles are not reported as intersecting. Call SetReportCoplanarIntersection(true) to handle this case (more expensive)
