NewtonMaterialGetContactTangentDirections

void NewtonMaterialGetContactTangentDirections (const NewtonMaterial* material, dFloat* dir0, dFloat* dir1);

Usage

Get the contact tangent vector to the contact point.

Parameters

• const NewtonMaterial* material - pointer to a material contact joint
• dFloat *dir0 - pointer to an array of at least three floats to hold the contact primary tangent vector.
• dFloat *dir1 - pointer to an array of at least three floats to hold the contact secondary tangent vector.

Return

• Nothing.

Remarks

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