NewtonMaterialGetContactTangentSpeed

NewtonMaterialGetContactTangentSpeed

dFloat NewtonMaterialGetContactTangentSpeed (const NewtonMaterial* material, int index);

Usage

Calculate the speed of this contact along the tangent vector of the contact.

Parameters

• const NewtonMaterial* material - pointer to a material contact joint
• int index - index to the tangent vector. This value can be 0 for primary tangent direction or 1 for the secondary tangent direction.

Return

• Contact tangent speed.

Remarks

• This function can only be called from a material callback event handler (NewtonContactsProcess).
