Description

This node allows users to capture surfaces lit from multiple angles to generate a delit colour map, as well as a high quality normal map.



Tips


  • Images are best captured in laboratory like conditions
  • Ideally the only light incident on the surface is deliberate artificial light from a single orchestrated direction.
  • ArtEngine supports 4 or 8 evenly spaced light directions
  • The camera and subject must remain stationary throughout


Parameters

Inputs: 
    • Four or Eight ports:
      Images must be added in sequential order, either clockwise or counterclockwise

  • Properties:
    • # of Angles:
      ArtEngine can process either four or eight photos, this control allows users to choose how many.
    • Light direction widget:
      The algorithm needs to know from which direction the light is coming from in the first image added to the node.
    • Direction:
      The algorithm needs to know in which direction the light travels in sequence, either clockwise, or counterclockwise.
    • Flatten Scan:
      Equalise the light across the input color map more harshly.
    • Normal Intensity:
      Increase or decrease the resultant normal maps intensity.



How to use

Expand
titleStep by step guide
  1. Add the Multi-Angle to Texture node from the node library (you can find the node in the 'Material' category)
  2. Add the captured images in to the node graph
  3. Choose between whether you have four or eight input images
  4. Connect the images in order to the node
  5. In the property panel define whether the ordered images are rotating clockwise or anti clockwise using the direction dropdown
  6. In the property panel define where the first light source originated from using the widget or the associated dropdown list

  7. The resultant normal map is sometimes a little weak so you can adjust the normal intensity within the property panel
  8. Run the node with the execute button
