+|Data.Friction|Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction always works in the direction opposite to the direction in which the object is moving, or trying to move.|
+|Data.Restitution|The coefficient of restitution is a measure of how much kinetic energy remains after the collision of two bodies. Its value ranges from 0 to 1.|
+|Data.Density|It is the mass of a material substance per unit volume.|
+|Data.Sensor|A sensor is a device that detects and responds to some type of input from the physical environment.|

 When you have declared this kind of helper class in your unit, the TGorillaPhysicsSystem component will then show you a new method to be callable "AddInstanceCollider".
+==== Render Colliders ====
+You can render physics colliders for debugging purposes.
+The most easy way is to insert a TDummy component into your TGorillaViewport and leave all transformation (position, rotation and scaling) zero, to not affect collider rendering.
+The add a "OnRender" event with the following code.
+<file pascal>
+uses
+  Gorilla.Physics.Q3.Renderer;
+const
+{$IFDEF DEBUG}
+  SHOW_PHYSICS_COLLIDERS = true;
+{$ELSE}
+  SHOW_PHYSICS_COLLIDERS = false;
+{$ENDIF}
+procedure TForm1.Dummy1Render(Sender: TObject; Context: TContext3D);
+var LRender : TQ3Render;
+begin
+  // Check if we want to see physics colliders
+  if not SHOW_PHYSICS_COLLIDERS then
+    Exit;
+  // Here we render physics colliders for debugging
+  LRender.Context := Context;
+  GorillaPhysicsSystem1.Engine.Render(@LRender);
+end;
