Image Compositing for trueSpace7.61

Nodes for processing and combining images.  One of the nodes will convert a bump map to a normal map.  The nodes require the installation of an rsx plugin file, "Clintons3DPlugins.rsx".  Any previous downloads of the plugin will need to be updated with a fresh download.

Click this line to get the rsx plugin.

Click this line to get the composite node object library.

Click this line for an overview of the nodes.

Some video tutorials can be found by clicking this line.

The rsx file can be stored anywhere on your computer and the composite node library can be stored in the truespace rs main libraries folder for convenience.

All image calculations are performed in floating point so whiter than white and blacker than black values are preserved.  All input images must have the same dimensions.  None of the nodes are optimized for speed but written with coding simplicity in mind.

Check video below just after the Indigo installation for tip on how to install the rsx plugin.

May 6 2010: Update

• bug fix for color curve nodes
• color picker outputs colors in float form - not just 0 to 255
• added more color picker aspects
• "color 2 numbers" node for converting a color to float values
• replace "Image Shrink" with "Image Shrink or Zoom", use checkbox to zoom into the image and inputs to offset the upper left edge of the zoom
• encapsulated some nodes so their parameters can be animated
• alpha outputs limited to a range of 0 to 1
• fixed alpha bug in the image blur node
• changed "chroma key" to "color distance key" and normalized the output values
• fixed mask input of the gamma node
• added a bitmap input option for the mix node
• new small aspect so nodes fit into a smaller space

May 16 2010: Update

• minor fix for the Composite Render Node - turned off image compression

Image Plane background for trueSpace7.61

Node object for creating a background image or image sequence for a scene camera.

Usage:

1. Select the camera in the scene.
2. Push the connect to camera button.
3. Use the material editor to open the link editor to the prodigy object and push the large blue button to select an image sequence.
4. Return to the scene level and select the image plane.
5. Set the dimensions and the pixel aspect ratio of the image.
6. Set keyframes for the frame number attribute of the image plane.
7. Set the distance attribute to position the image plane behind the scene.

Indigo Render Export for trueSpace7.61

This is a modified version of the original Indigo script for trueSpace created by "Johny".  The definition from the Indigo home page: "Indigo is a photorealistic renderer which simulates the physics of light to achieve near-perfect image realism. Incorporating an advanced physical camera model, a super-realistic materials system and the ability to simulate extremely complex lighting situations through Metropolis Light Transport".  Click the title above or the image to the left to download the truespace to indigo package.

Bug Fix April 2010 Draft3-a, April 19 2010:
There was a bug in the original installer when trying to use environment maps.  The new installer can be downloaded here or you can just re-download the zip archive.  Answer "yes" to all the questions when reinstalling.

The plugin package Clintons3DPlugins is required to use the script.

Sample packaged scene can be downloaded here.

Click the link at the bottom of this section for important usage notes.  Below this point are release notes, installations notes and video tutorials.

  Added bumpmap support
  fixed bug in D3D material name
  Support exit portals
  Support multiple area lights
  Increase area light intensity by 10
  changed all gamma's to 2.2
  Use downloaded indigo materials
• November fixes
  • added the missing Indigo material name node
  • added a sample scene
  • multiply background environment by 10000 to brighten it up
  • set meshlight power to 100000
  • added power to rectangle light
  • set default environment map gain to 2 million
• November draft 2 fixes
  • new environment node for the scene that overrides the indigo script environment
  • the scene environment node has inputs for mesh and rectangle light power(watts) and efficiacy(lumens/watt) for controlling the brightness
  • check for texture image paths and igm file paths
  • fixed camera to properly use any aspect ratio render
  • fixed ambient light causes the script to crash
  • Indigo v2 exit portals only worked reliably with a very specific default material

 

Exporter Features:

• Works with Indigo version 2 and the last free version 1.1.18
• D3D materials for phong, diffuse, specular, diffuse transmitter, glossy transparent, oren-nayar, texture and bumpmaps
• Use Indigo materials from the official database
• Area lights convert to Indigo rectangle lights
• Mesh lights(the mesh emits light) - use emitter materials instead
• Exit portals(meshes that act like windows between the interior and exterior of a scene
• Get Indigo skylight orientation from truespace light added to the scene(name the light "Sky")
• IMEBank(Indigo Material Bank) for more control of exported materials

Installation:

1. Download and install the Indigo Renderer.  The latest version is here and the last free version, 1.1.18, is here.  The unlicensed commercial version is restricted to 800x600 resolution, cannot be used for commercial purposes, no render farming allowed and you can't remove the Indigo watermark.  The free version can be used for commercial purposes but not in a render farm.
2. Download and unzip the archive to an existing library place or create a new one with the library browser. Manual Chapter 2 pg 22
3. Load the installer into the link editor and run it to create a button/toolbar.
4. Push the button and choose the Setup aspect.  If you are using the latest version(2) push the button to get the location of the indigo executable from the windows registry.  If using the old version(1) use the file browse button to find the "indigo.exe" file.
5. Install and Load the plugin, Clintons3dplugin.rsx, using the Package manager. Manual Chapter 2 pg 161-162

Note: I failed to mention in the video that scene material instancing must be used.
Note: You can open a new 3D for the camera and set it's dimensions to the render size for a better preview.

note: You're not limited to the 5 materials in the IMEBank.  You can copy items in the bank and make variations to use in the scene.
Note: The reset material is a D3D material, but it is ignored by the Indigo exporter.  The D3D materials that are made of nodes that feed into a material node are not ignored and will override IMEBank materials.

Some usage notes:

Stereo 3D for trueSpace7.61

Node object for displaying anaglyph style(red/cyan or magenta/green) 3D stereo images. Load the object, initialize the screen, use the select 3d camera button and set the 3D view to use it.

Controls:

• camera field of view
• eye separation and convergence
• red and cyan(magenta and green) intensity
• background color
• height and width of projected image in pixels
• choose red/cyan or magenta/green glasses

Update version 3.04:

• fills the viewport better and matches non-anaglyph view better
• fixed aspect ration, it was a little stretched horizontally
• added selector buttons for left and right camera to view the scene without 3D effects
• screen has 2 to 1 aspect for a wider screen
• exported projection plane dimensions to control width
  

modelspace d3d render

Installs a button that runs a script for combining modelspace and workspace animations into one d3d workspace render sequence.  Script can also be used to bake workspace animations to modelspace animation via autokey setting in modelspace.

Set playback range in workspace, setup render to file to save a sequence, have workspace and model space 3d views open and run the script. Can be used to bake workspace animation to modelspace. Works with transformation, vertex animation, particles and facial animation. Does not work with metaball animation.

See the notes tab of the node for more details.
