awViewing.Intersector Class Reference
Detailed Description
Intersector performs an intersection test for a given screen point and stores a list of intersections.
Public Member Functions |

| __init__ () | |
| bool | intersect (float x, float y) |
| Returns true if any object in the scene was
hit by a ray projected into the scene. |
|
| int | hitCount () |
| Returns the number of hits. |
|
| awScene::NodeRef | getHit (int index) |
| Returns the node for a particular hit.

index. |

| awViewing.Intersector.__init__ | ( | ) |
| bool awViewing.Intersector.intersect | ( | float | x, |
| float | y | ||
| ) |
Returns true if any object in the scene was hit by a ray projected into the scene.
| int awViewing.Intersector.hitCount | ( | ) |
Returns the number of hits.
| awScene::NodeRef awViewing.Intersector.getHit | ( | int | index | ) |
Returns the node for a particular hit.
| awLinear::Point awViewing.Intersector.getIntersectionPoint | ( | int | index | ) |
Returns the the intersection point by index.
If there is no intersection, then the origin is returned.
| awLinear::Normal awViewing.Intersector.getNormalAtIntersection | ( | int | index | ) |
Returns the normal at the intersection by index.
If there is no intersection, then a zero vector is returned.
| int awViewing.Intersector.getPatchIndexAtIntersection | ( | awScene::NodeRef | node, |
| int | index | ||
| ) |
Returns the patch index at the intersection by index.
If there is no intersection, -1 is returned. Node is necessary in order to map back into the original file indices, instead of the potentially optimized one.
| awLinear::Point2 awViewing.Intersector.getUVAtIntersection | ( | int | index | ) |
Returns the uv at the intersection by index.
If there is no intersection, then a zero vector is returned. You must make sure that the specified index is less than the hit count.
