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.
|
|
awLinear Point | getIntersectionPoint (int index) |
Returns the the intersection point by index.
|
|
awLinear Normal | getNormalAtIntersection (int index) |
Returns the normal at the intersection by
index. |
|
float | getDistanceAtIntersection (int index) |
Returns the distance to the intersection by
index. |
|
int | getPatchIndexAtIntersection (awScene.NodeRef node, int index) |
Returns the patch index at the intersection
by index. |
|
awLinear Point2 | getUVAtIntersection (int index) |
Returns the uv at the intersection by index.
|

bool | intersectManips (float x, float y, awScene.NodeRef startNode) |

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.
float awViewing.Intersector.getDistanceAtIntersection | ( | int | index | ) |
Returns the distance to the intersection by index.
Return -1.0 if index is out of range.
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.
