struct IPhysRenderer {
};

physinterface.h

this is a callback interface for debug rendering, physics gets a pointer to an implementation

virtual ~IPhysRenderer();

virtual void DrawGeometry(IGeometry * pGeom, struct geom_world_data * pgwd, int idxColor = 0, int bSlowFadein = 0, const Vec3 & sweepDir = Vec3(0)) = 0;

draws helpers for the specified geometry (idxColor is in 0..7 range)

virtual void DrawLine(const Vec3& pt0, const Vec3& pt1, int idxColor = 0, int bSlowFadein = 0) = 0;

draws a line for wireframe helpers

virtual void DrawText(const Vec3 & pt, const char * txt, int idxColor, float saturation = 0) = 0;

draws a text line (stauration is 0..1 and is currently used to represent stress level on a breakable joint)

virtual const char * GetForeignName(void * pForeignData, int iForeignData, int iForeignFlags) = 0;

gets a descriptive name of the phys entity's owner (used solely for debug output)

virtual Vec3 SetOffset(const Vec3 & offs = Vec3(ZERO)) = 0;

sets an offset that is to be added to all subsequent draw requests
