Summary
[edit]

The Kinect Azure Select TOP can be used to capture additional images from a Microsoft Kinect Azure camera that is controlled by a Kinect Azure TOP.

NOTE: This TOP requries Microsoft Windows 10 April 2018 or newer. An NVIDIA GEFORCE GTX 1070 or better graphics card is required to efficiently obtain body tracking data from the camera; however, a slower CPU-only mode can also be enabled using the parameters.

This TOP must be used along with a Kinect Azure TOP.

Parameters - Kinect Azure Page

Active active - Controls whether this TOP is retrieving image data from the device. The primary Kinect Azure TOP must also be active to receive data.  

Kinect Azure TOP top - The name of the primary Kinect Azure TOP that is configuring the camera. The primary TOP controls which camera the select TOP receives data from, as well as all device configuration such as resolution, framerate, etc.  

Image image - - A list of available image types to capture from the device and display in this TOP. All image types have a second version that is mapped (aligned) to the image space of the other camera so that color and depth image data can be matched. The resolution of the image is controlled by the Color Resolution or Depth Mode parameters of the primary Kinect Azure TOP.

  • Color color - An 8-bit RGBA image from the color camera.
  • Color aligned to Depth colorremap - The color camera image remapped to align with the current depth camera image. The resolution is determined by the Depth Mode.
  • Depth depth - A single channel 32-bit floating point depth image where pixel values measure the distance in meters from the camera. Resolution and field of view are determined by the Depth Mode parameter.
  • Depth aligned to Color depthremap - The depth image remapped to align with the current color camera image. The resolution is determined by the Color Resolution.
  • IR ir - A 16-bit integer infrared image captured by the depth camera. Resolution and field of view are determined by the Depth Mode.
  • IR aligned to Color irremap - The infrared image remapped to align the current color camera image. The resolution is determined by the Color Resolution parameter.
  • Player Index playerindex - An 8-bit single channel image that maps pixels to players that have been identified by the body tracking system. Pixel values represent the body id multiplied by 25 to improve contrast. Note: The player index map may have additional hardware requirements (CUDA capable graphics card) and may not synchronize with the color or depth images depending on current settings. The resolution is determined by the current Depth Mode.
  • Player Index aligned to Color playerindexremap - The player index map remapped to align with the current color image. The resolution is determined by the Color Resolution parameter.
  • Point Cloud pointcloud - A 32bit floating point RGBA image where the depth information has been converted into XYZ positions that are stored in the RGB channels. Position data is represented in meters and the resolution and field of view are determined by the Depth Mode. The Point Cloud image can be viewed in 3D by activating the TOP and selecting 'View as Points' in the right-click menu, or by using the TOP as an instance source in the Geometry COMP.
  • Point Cloud aligned to Color pointcloudremap - The point cloud image remapped to align with the current color image. Note: Remapping the image can create gaps and artifacts when view the points in 3D.

Align Image to Other Camera remapimage - When enabled, the current image will be remapped to align with images from the other camera. For example, use this feature to create a color camera image that maps to the pixels of the depth camera. The current depth mode and color resolution will be used to do the remapping. Note: Remapping the point cloud image can create artifacts in the distribution of points due to gaps in the remapping algorithm.  

Sync Image to Body Tracking bodyimage - When enabled, the image produced will be delayed so that it corresponds to the most recent data from the body tracking system.  

Mirror Image mirrorimage - Flip the image in the horizontal axis.  


Parameters - Common Page

Output Resolution outputresolution - - quickly change the resolution of the TOP's data.

  • Use Input useinput - Uses the input's resolution.
  • Eighth eighth - Multiply the input's resolution by that amount.
  • Quarter quarter - Multiply the input's resolution by that amount.
  • Half half - Multiply the input's resolution by that amount.
  • 2X 2x - Multiply the input's resolution by that amount.
  • 4X 4x - Multiply the input's resolution by that amount.
  • 8X 8x - Multiply the input's resolution by that amount.
  • Fit Resolution fit - Grow or shrink the input resolution to fit this resolution, while keeping the aspect ratio the same.
  • Limit Resolution limit - Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same.
  • Custom Resolution custom - Directly control the width and height.

Resolution resolution - - Enabled only when the Resolution parameter is set to Custom Resolution. Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.

  • W resolutionw -
  • H resolutionh -

Resolution Menu resmenu -  

Use Global Res Multiplier resmult - Uses the Global Resolution Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Resolution Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this TOP is affected by the global multiplier.  

Output Aspect outputaspect - - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)

  • Use Input useinput - Uses the input's aspect ratio.
  • Resolution resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square.
  • Custom Aspect custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.

Aspect aspect - - Use when Output Aspect parameter is set to Custom Aspect.

  • Aspect1 aspect1 -
  • Aspect2 aspect2 -

Aspect Menu armenu -  

Input Smoothness inputfiltertype - - This controls pixel filtering on the input image of the TOP.

  • Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
  • Interpolate Pixels linear - Uses linear filtering between pixels. This is how you get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
  • Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.

Fill Viewer fillmode - - Determine how the TOP image is displayed in the viewer. NOTE:To get an understanding of how TOPs work with images, you will want to set this to Native Resolution as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.

  • Use Input useinput - Uses the same Fill Viewer settings as it's input.
  • Fill fill - Stretches the image to fit the edges of the viewer.
  • Fit Horizontal width - Stretches image to fit viewer horizontally.
  • Fit Vertical height - Stretches image to fit viewer vertically.
  • Fit Best best - Stretches or squashes image so no part of image is cropped.
  • Fit Outside outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer.
  • Native Resolution nativeres - Displays the native resolution of the image in the viewer.

Viewer Smoothness filtertype - - This controls pixel filtering in the viewers.

  • Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
  • Interpolate Pixels linear - Uses linear filtering between pixels. Use this to get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
  • Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).

Passes npasses - Duplicates the operation of the TOP the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected TOP's image.  

Channel Mask chanmask - Allows you to choose which channels (R, G, B, or A) the TOP will operate on. All channels are selected by default.  

Pixel Format format - - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.

  • Use Input useinput - Uses the input's pixel format.
  • 8-bit fixed (RGBA) rgba8fixed - Uses 8-bit integer values for each channel.
  • sRGB 8-bit fixed (RGBA) srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB.

[[Category:TOPs ]]

An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

The width and height of an image in pixels. Most TOPs, like the Movie File In TOP can set the image resolution. See Aspect Ratio for the width/height ratio of an image, taking into account non-square pixels.

Each SOP has a list of Points. Each point has an XYZ 3D position value plus other optional attributes. Each polygon Primitive is defined by a vertex list, which is list of point numbers.

An Operator Family that contains its own Network inside. There are twelve 3D Object Component and eight 2D Panel Component types. See also Network Path.

The viewer of a node can be (1) the interior of a node (the Node Viewer), (2) a floating window (RMB->View... on node), or (3) a Pane that graphically shows the results of an operator.

A CHOP outputs one or more channels, where a channel is simply a sequence of numbers, representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. See also Export.
