2.1 Input colouring and parameters


Z Vector has five different input colour modes (from top to bottom):

  • No color
  • Intensity (gray scale)
  • Inverted RGB
  • RGB
  • Generated gray scale

Pressing the corresponding button can activate any of the five modes.

For an example on how to use these various modes for different looks, try turning on the RGB colouring mode from the input and manoeuvre to the Controls tab. Next turn up Gradient/Fill to maximum and choose Intensity from the Gradient/Mode. Now try playing with the scale value (a relatively small one should give you immediate effects). This will essentially recolor the RGB texture with the colors of your chosen gradient.

Below the colouring modes are two buttons with the text “LNK” and “REC”. Clicking LNK (for link) puts the two input modes in to linked mode, where pushing a button on one leads to a similar result on the other and playback is synchronised. This mode is covered in more detail in the advanced tutorials. For now, for the purposes of completing this tutorial series, leave linked mode off.

Clicking REC (for record) starts the recording of an .rgbd file of the input. This custom file format has been specifically developed to store depth and texturing information for the various sensor types Z Vector supports. It replaces the .oni (OpenNI) file format previously available in Z Vector (V1.10>). The old file format is no longer supported (no conversion process is currently in the planning). Recorded files can be played back from the Triggers section.
