-
class PxGjkQueryExt
Pre-made support mapping for built-in convex geometry types.
Public Static Functions
-
static bool generateContacts(const PxGjkQuery::Support &a, const PxGjkQuery::Support &b, const PxTransform &poseA, const PxTransform &poseB, PxReal contactDistance, PxReal toleranceLength, PxContactBuffer &contactBuffer)
Generates a contact point between two shapes using GJK-EPA algorithm.
- Parameters
a – [in] Shape A support mapping
b – [in] Shape B support mapping
poseA – [in] Shape A transformation
poseB – [in] Shape B transformation
contactDistance – [in] The distance at which contacts begin to be generated between the shapes
toleranceLength – [in] The toleranceLength. Used for scaling distance-based thresholds internally to produce appropriate results given simulations in different units
contactBuffer – [out] A buffer to store the contact
- Returns
True if there is a contact.
