Types¶
Ray (struct)¶
The Ray type represents linear 3D ray. This is expressed by a start and direction Vec3
/*
** Example: Ray
*/
Ray ray(Vec3(0.0, 0.0, 0.0), Vec3(0.1, -1.0, 0.4));
Methods¶
| Ray ( in Ray other ) | |
| Ray ( in Vec3 start, in Vec3 direction ) | |
| Ray () | |
| Ray | clone ? () |
| Scalar | distanceToPoint ? ( in Vec3 point, out Scalar rayParam ) |
| UInt32 | hash ? () |
| Boolean | intersectBoundingBox ? ( in Box3 box3 ) |

Functions¶
twoPlaneIntersection¶
twoPlaneIntersection ( in Vec3 plane1Point, in Vec3 plane1Normal, in Vec3 plane2Point, in Vec3 plane2Normal, io Vec3 linePoint, io Vec3 lineVector )
Computes the intersection point of two planes. The planes are each defined as a point and a normal. Returns the intersection point. linePoint will be set to plane1Point.
注釈
If lineVector is :ref:`Vec3 <vec3>`() it means that the planes are either intersecting nowhere or everywhere. In this case
| plane1Point | The first plane’s position |
| plane1Normal | The first plane’s normal (must be a unit in length) |
| plane2Point | The second plane’s position |
| plane2Normal | The second plane’s normal (must be a unit in length) |
| linePoint | The intersection point of the 2 planes. |
| lineVector | The intersection vector of the 2 planes. |
