| const [pure virtual] |
Perform a ray cast against the convex hull.
- Parameters:
-
| in | this MUST be set to the minimum 'time' that you wish to have reported for intersection. you may consider this an origin offset for the ray. On exit, if the hull is intersected, this value will contain the time of intersection, or its original value, which ever is larger. |
| out | this MUST be set to the maximum 'time' that you wish to have reported for intersection. you may consider this the endpoint of a line segment intersection. On exit, if the hull is intersected, this value will contain the time that the ray exits the hull, or its original value, which ever is smaller. |
| orig | describe the ray to intersect with the convex hull. |
| dir | describe the ray to intersect with the convex hull. |
| localToWorldRT | the rotation applied to the convex hull. |
| scale | the scale applied to the convex hull. |
| normal | if not NULL, *normal will contain the surface normal of the convex hull at the point of intersection (at the 'in' time). If the point on the ray at the 'in' time lies within the volume of the convex hull, then *normal will be set to (0,0,0). |
- Returns:
- returns true if the line segment described by the user's supplied 'in' and 'out' parameters along the ray intersects the convex hull, false otherwise.
| virtual bool nvidia::apex::ExplicitHierarchicalMesh::ConvexHull::reduceHull |

maxFaceCount, |
|
|
bool |
inflated |
|
) |
| [pure virtual] |
Removes vertices from the hull until the bounds given in the function's parameters are met. If inflated = true, then the maximum counts given are compared with the cooked hull, which may have higher counts due to beveling.
- Note:
- a value of zero indicates no limit, effectively infinite.
- Returns:
- true if successful, i.e. the limits were met. False otherwise.
| virtual void nvidia::apex::ExplicitHierarchicalMesh::ConvexHull::release |
( |
| ) |
[pure virtual] |
Releases all memory associated with this object and deletes itself.
