Clintons3dPlugin package for trueSpace

This rsx plugin is used by several scripts from this site. It is used in the unreal scripts to read the binary formats and in the indigo script making it possible to read scene level materials. Several scripts now use the Save-As dialog from this package.

The source code for the plugin can be downloaded from here.
ExamplesPlugin.TopologyExample2 = ImportPSK
ExamplesPlugin.TopologyExample4 = ImportPSA
ExamplesPlugin.TopologyExample5 = import collada
ExamplesPlugin.HelloWorld2 = ExportPSK
ExamplesPlugin.HelloWorld3 = ExportPSA
ExampleDataObject2 = guid for scene materials
ExampleDataObject3 = save as dialog
ExampleDataObject4 = triangle neighbors/polygon functions
compositing nodes
UtilityDataObject - node connector info, select file folder dialog, save as dialog, set active material, guid for scene materials, point visualization, keyframe data info

Be warned that much of the source code is very rough. I never fully figured out how to use the beta sdk, so it's a messy collection of code that works. Also the source is a little bloated from extra libraries and experimentation.

A version of this rsx plugin comes pre-installed in the Unofficial trueSpace Updates -

polygon to triangles using Newells Method

feed it a list of vertices space delimited "x1 y1 z1 x2 y2 z2 ..."

get back triangle data "#triangles,i1 j1 k1,i2 j2 k2, ..."

polypoints = "-0.5 -0.5 -0.5 -0.5 -0.5 0.5 -0.5 0.5 0.5 -0.5 0.5 -0.5"
utilitydata = System.CreateDO("Clintons3D Package/Utility functions");
value = utilitydata.PolygonToTriangles(polypoints);
valArr = value.split(",");
for(var i = 0; i < valArr[0]*1; i++) {
	localindices = valArr[i+1].split(" ");

a little sloppy trailing space and comma in each triangle definition
value is "2,0 1 2 ,0 2 3 ,"

triangle neighbors

triangle neighbors diagram
//get triangle neighbors as a space delimited string of triangle indices
utilityFunctions = System.CreateDO("Clintons3D Package/Utility functions");
triangleIndex = 19;
neighborsS = utilityFunctions.GetTriangleNeighbors(firstSelected + "/Editable shape", triangleIndex);

result is "5 20 16", a space delimited list of neighbor indices at each edge of the triangle, -1 indicates no neighbor on that edge

the first value is the triangle index along the edge P1>P2, then P2>P3 and finally P3>P1

triangle edge visibility

meshdata = System.CreateDO("Space 3D Package/Mesh Data");
faceEdgeStream = System.CreateDO('Space 3D Package/Face Edges Stream Data');
meshdata = Node.Value(Node.FirstSelected() + "/Editable shape" ,"Mesh");
faceEdgeStream = meshdata.GetTrianglesStreamByName("Face Edges Stream Data");
triangleIndex = 19;
triangleEdgesS = faceEdgeStream.edges(triangleIndex);

result is the value of 1 to show that the first edge of the triangle is visible. if the second edge was also visible the value would be 1+2=3 and if the third edge was also visible it would be 1+2+4=7

truespace does not store polygon information. it stores triangle edge visibility to give the appearance and behavior of polygons

height node

Height field node

point cloud test

A fast version of the Caligari Image Cloud script created by Norm Fortier and based on the SDK height field sample code.


  • Bitmap - texture image for the mesh faces if they are visible
  • Height field - texture to control the height and color of the points
  • Height segments - vertical resolution of the mesh
  • Method - how the height is generated
    • 0 - average value of the red, blue and green of the pixel
    • 1 - use the blue value
    • 2 - use the green value
    • 3 - use the red value
    • 4 - intensity/luminance (0.3*red + 0.59*green + 0.11*blue)
    • 5 - use the alpha value of the image
  • Multiplier - scale for the displacement values
  • Point alpha - if checked the transparency value of the points is determined by the alpha channel of the image
  • Point size - how large the points are
  • Surface Opacity - how opacity of the mesh faces, 0=invisible
  • Width segments - the horizontal resolution of the mesh

The plugin package is required to use this script. Download the plugin package here.

A bare bones height field node can be created by running a command:
Node.Create('Clintons3D Package/Height field',Space.CurrentScene());

material matching

Object scene material guid reader

This script demonstrates how to get the guid for object scene materials which are not available to scripting. Each material inside the scene's material node has a unique id assigned to it that can be read by script. The corresponding id is found inside the meshes "Material List" node. On the node connected to the "Material List Manager". Pass this node to the plugin to get it's id and match it against the "Material Flavor Manager's" "Material ID" connector value.

Select the node connected to the Material List Manager and push the button for the script to display the id in the list view.

By the way the "Material ID" connector on the "Material Flavor Manager" is hidden and can't be seen on the node even though it can be read via script.

The plugin package is required to use this script. Download the plugin package here.

Save As Dialog (v2) for trueSpace

The plugin package is required. Download the plugin package here.

Sample Code:

var fso = new ActiveXObject("Scripting.FileSystemObject");
var util = System.CreateDO("Clintons3D Package/Utility functions");
var folder = "";
var filename = "some preexisting filename";
folder = fso.GetParentFolderName(filename);
filename = fso.GetFileName(filename);
//fso method return of folder or filename is flawed when path is invalid/empty
//causes returned value of plugin to cause tS crash
if(folder=="") folder="";
if(filename=="") filename="";
var defExt = "tga";
var filter = "TGA (*.tga)~*.tga~EXR (*.exr)~*.exr~HDR (*.hdr)~*.hdr~Jpeg (*.jpg)~*.jpg~PNG (*.png)~*.png~TIF (*.tif)~*.tif~All Files (*.*)~*.*~~";
var file = util.FileSaveAsDialog2(folder, filename, filter, defExt);

Light Passthrough and Light Attribute Transfer for trueSpace7.61

2 part script for transferring a lights spot angle and color to an objects position, rotation and scale. One script goes inside the light. The other resides at the scene level.


  1. Place the lightPassthrough script node inside the light encapsulator.
  2. Export the 2 output connectors, "angleOut" and "colorOut"
  3. Connect the "angleIn" to the outside through the "Angle" connector on the encapsulator.  Skip this step if the light isn't a spot light or the cone angle isn't animated.
  4. Connect the "colorIn" to the outside via the "Color" input connector.
  5. Add the lightAttrTransfer node to the scene level.
  6. Expand the light and connect the angleOut to the spotAngle input of the lightAttrTransfer node.
  7. Connect the colorOut of the light to the lightColor input of the lightAttrTransfer.
  8. Connect the matrixOut of the lightAttrTransfer to an object in the scene.

Now when the scene is exported to collada format the object's transforms will hold the cone angle and color animations for the light. Rotate X will hold the spot angle in degrees. Scale XYZ and Translate XYZ will hold the color values. Translate X is only valid if imported with a scale of 1. If pick whip on scale in After Effects then divide by 100 since AE converts scale 0-1 to 0-100.

Note: There is a script for an Enhanced Collada export that includes light cone and color animation export.

Camera FOV Attribute Transfer for trueSpace7.61

Script for transferring the camera FOV to an objects position, rotation and scale.


  1. Set camera to "Exp" aspect in the LE
  2. Connect Camera output to the cam input
  3. Connect the MatrixOut to some object in the scene

Now when the scene is exported to collada format the object's transforms will hold the FOV animation for the camera. Rotate X will hold the fov in degrees. Scale X and Translate X will hold an After Effects compatible zoom value. Translate X is only valid if imported with a scale of 1 and the After Effects zoom is via pick whip and multiply by the composition height. If pick whip on scale also divide by 100 since AE converts scale 0-1 to 0-100.

Note: The collada exporter exports the camera fov from model space values and ignores the work space fov value.

Note: There is a script for an Enhanced Collada export that includes the camera's fov animation.

Procedural Modelling - Stool


Adapted from a 3DBuzz Houdini Tutorial


  • Watchdog responds to all connectors of single script object - one changes and all will send a signal to the watchdog. Maybe better to have changes that require a command script execution be on their own nodes.
  • uses an external mesh object parent for the leg, acting as a pivot for the leg
  • combines meshes via a command script combined with a Csg operation node
  • command node calls second command using ScriptObject.Execute to force synchronous update for truespace items
  • the masterControl node outputs were created via a utility script, Generate Outputs
April 11, 2019

Generate Outputs

generate outputs panel

Utility script that will read an exported scripts xml file, read the input parameters and create a new xml file with corresponding output parameters.


  1. use the Export Script button to save an xml file
  2. choose the xml file with the ... button and press Start
  3. a new file is create - filename.xml => filename_Processed.xml
  4. use the Import Script button on the new xml file


  • uses "Msxml2.DOMDocument.6.0"
  • each "parameter" will have a corresponding "parameterOUT" connector
  • CDATA is ignored and simply copied to the new file
  • can transfer between script objects and command scripts by editing the first lines after importing (Execute, OnComputeInputs...)

Flip Animation Scene

Inspired by Blender Animation nodes

flip tile node tree


  • torus distance from each tile is used to determine the amount of rotation on a tile
  • GridArray_Cube node is an updated script derived from the soon to be old grid array script utility
  • The distances script object computes distances from each tile to the torus outputing a number array.
  • The Number Array MapRange script object scales the values of the distances number array to result in a rotation in pitch between 0 and 180 degrees for each tile.
  • The FlipCones node performs the rotations of the tiles found inside the GridArray_Cube node using values from the number array output of the MapRange node.
  • The target tiles are defined by selecting the first clone, "meshObj"

Sphere Collapse Scene

Inspired by Blender Animation nodes


  1. select the Cube
  2. press the Copy Mesh button to populate the cubes
  3. press the Look at Center button to orient the cubes
  4. press the Select Effector to select the Torus
  5. move the Torus around


  • Blender icosphere with 4 sub divs = 642 vertices. truespace set sphere resolution to 8 to match
  • predates the lookat math - instead uses a tailref cube connected to a headref cube via a lookat node
    • the headref is placed at (0,0,0)
    • the tailref is placed at the vertex locations of the larger sphere
    • the tailref rotation is read and copied to the individual cube matrix

Countdown Scene

Inspired by Blender Animation nodes


  • Final mesh output uses a "mesh instancer" node
  • Uses 3 array point accumulators to create the grid of position values for the hexagonal shapes
  • The countdown text and an invisible cube are joined together with a csg node set for intersection mode. The cube is moved to the position of each array point and the csg resulting mesh is read in. If the resulting mesh is not empty, then that hexagon shape moves up.
  • The noise motion comes from a image cloud node
  • The wave image is made from the linearGradient image included in the trueSpace Unofficial Update combined with an image curve node. It is animated using an image crop node.
  • The material uses a vertex shader to blend between the colors.
  • Uses animation of a torus going up and down to control the numbers motion. RsAnim.PutFrame is used to set the time on the torus, then it's z value was read in as a control. PutFrame only effects the one item and does not effect the rest of the scenes animations.

Instancer.RsObj - used to create a single mesh from many copies.

Array Points.RsObj - creates a 1D line of vertices given a count and offset values

Array Points Accumulator.RsObj - same as array points but takes a vertex list input to create 2D and 3D vertex arrays
