NewtonCollisionTreeRayCastCallback

NewtonCollisionTreeRayCastCallback

typedef dFloat (*NewtonCollisionTreeRayCastCallback) (const NewtonBody* const body, const NewtonCollision* const treeCollision, dFloat intersection, dFloat* const normal, int faceId, void* const usedData)

Usage

This callback lets you implement your own custom collision tree raycast method (see: NewtonTreeCollisionSetUserRayCastCallback)

Parameters

• body NewtonBody*
• treeCollision NewtonCollision*
• dFloat interception - current raycast check distance
• dFloat* normal - Hit Normal is returned here.
• int faceId - current faceid (the faceAttribute parameter set in the NewtonTreeCollisionAddFace function )
• void* userData - current collision's user data.

Return

• Return the distance at which a object was hit return 1.0 if nothing was hit.

Remarks

• This is not a library function, but a callback event.
