Item Info

Bone ID

Select the object and appropriate bone and the node outputs the bone state.

Bone Info

Outputs bone item ID, and the item ID of the owning object, of the bone selected in its settings.

Camera

This is a standalone node that provides access to a camera’s current settings. Any of the cameras in the current scene may be selected by double-clicking on the node. The outputs are then derived from the settings for the selected camera.

Edit Panel

The Render Camera is the one used on a specific frame for rendering but you can also choose other scene cameras if you want to base the surface on a camera positioned differently.

Device

The Device node initially appears with no connections at all. You will need to double-click on it to open this requester:

You can either type over the (enter name) text or select from the dropdown menu. If your devices are not found you may need to visit the Virtual Studio > Device Manager window and make sure the device type you wish to use is enabled. Manager Names choices are:

• HID - The Microsoft Human Interface Device standard is home to many mice and other devices and is your first port of call

• Intersense - A manufacturer of high-end virtual cameras

• Kinect for Windows - to use the Kinect device for motion capture or surfacing

• PS3 Move.Me - A system to use the PlayStation 3 Eye Toy camera

Device Name can be a vast list of devices if HID is chosen as the Manager type. Once you have chosen a Manager and Device, the Device icon will look like this:

You can now connect the outputs from this device into your network. Most devices aren’t very useful for creating a surface, this one is more useful for the Virtual Studio part of Layout. However, they are still available since The Control Booth panel part of Virtual Studio does have access to the button presses for Virtual Studio devices. An LScript or Python script or Generic plugin can be assigned to the button press. Arguments to pass to the command can be specified in the Control Booth as well.

Dynamics Part Info

For use with Bullet Dynamics object, this node enables control over the individual elements of a Parts object. This node has no panel just connections.

Inputs are the Item ID of the dynamics body, and either the Part Number or the Polygon Index. If the part number is connected it will use that part, otherwise it will use the polygon index to figure out the part that the polygon is in. If the item or polygon index are not connected, the node will get them from the evaluation context.

Outputs are:

• Part Number - the index of the part

• Internal Polygon - 1 if the polygon is currently internal, 0 otherwise

• Part World Position/Right/Up/Forward/Rotation - current transform of the part in world coordinates

For parts objects, internal polygons are those that join two parts together. When the parts break those polygon stop being internal and become part of the outer surface.

If the object is transparent, like glass, you probably don't want internal polygons to show until the glass fractures. You can achieve that in a nodal shader by hooking the Internal Polygon output to the Clip input of the Surface node. Or alternatively use it to switch between two different materials or material properties.

Another use of the Dynamics Part Info node is in a nodal motion setup to track the position and orientation of a particular dynamic part. Hook up an Item ID node to the Item ID input to select the dynamics item, an Integer constant node to the part number to select the part, and use the part position and rotation outputs to get the motion.

Note that the position and orientation is for the center of mass of the part, not the pivot of the item.

tip

Note that this node works from Frame 1 of a dynamics simulation. At Frame 0 it is not yet activated

Item ID

Double-clicking on this node will open a window with all scene items in a dropdown list. The single integer output gives the item's ID.

Item Info

This node can report on an item in a scene: Object, Light or Camera (for Bones, use the Bone Info node). It gives details the item’s position, rotation and other vector information.

New to 2018

note

Item Info now has an Item ID input rather than just double-clicking on the node to choose a scene item.

Edit Panel

Light Info

This is a standalone node that provides access to a light’s current settings. Any of the lights in the current scene may be selected by double clicking on the node. The outputs are then derived from the settings for the selected light.

Mesh Info

Input item ID of an object and a point index, outputs info about that point.

Mesh Part

Gets information about the mesh part the current vertex is in

Mesh Tangent

Input item ID of an object and a point index, outputs the tangent, normal, and binormal directions at that point. Tangent is based on texture coordinate direction specified in the node's settings.

Mesh Vertex Find

Input item ID of an object and a position in object coordinates, outputs the point index of the vertex matching that position in either base or final deformed coordinates depending on the node's settings.

Studio Trait

This node is intended for use with LightWave’s Virtual Studio. It can be made use of in the Surface Editor, but similar outputs are available without the setup needed to use a Studio Trait node. If you would still like to use it, you will need to choose your scene item, go into its Motion Options and add the Virtual Studio Trait modifier. At that point, it becomes visible to the Studio Trait node and can be selected. You will get vector outputs of **Position **, Rotation and Scale.

Time

Information about the current scene time and frame
