 +
'''Q: I want to pay in a currency other than USD. But I found that the currency conversion rate is much higher than what I expected to have. Why is that?'''
 +
 
 +
'''A:''' We use Share-It international payments gateway to sell our software. If you want to pay in currency other than product price currency (USD) they add about 10% to the cost as their insurance from currency rates fluctuations. Proper way to avoid this overhead expense — please make order in USD (you can select order currency at the top of the order form). If you pay by card or PayPal, internal rates of payment system will be applied. They are usually very close to real exchange rates.

'''Q: Which configuration do you recommend: [[User Guide for Dual Depth Sensor Configuration|Dual depth sensors]] or [[User Guide for Multiple PlayStation Eye Cameras Configuration|Multiple Sony PS Eye]]?'''  
  
−
'''A:''' Express Edition:
+
'''A:''' There is no straighforward answer to this question, there are pros and cons each option: [[Dual Depth Sensors vs Sony PS Eye Comparison]]
−
* supports only 1 Microsoft Kinect sensor
+
−
* capture volume will be 7 by 7 feet (approx. 2 by 2 meters)
+
−
* you will not be able to track complex motions that include rotations because of self occlusion.
+
−
* but you will not need multi-camera system calibration, that makes Express Edition much easier in operation compared to other editions (that are multi-camera)
+
−
Basic and Standard Editions:
+
−
* support of 1 Kinect is included in Basic and Standard Editions as well
+
−
* you will also have bigger capture volume - 20 by 20 feet (approx. 7 by 7 meters)

+
  
−
'''Q: What is the difference between Express Edition and Standard Edition?'''
 
  
−

=== All editions ===
 
−
'''Q: Is there version for Mac?'''
 
  
−
'''A:''' To run this software on Mac you need to install Windows on it using [http://www.apple.com/macosx/compatibility/ Boot Camp] or [http://www.parallels.com/products/desktop/ Parallels Desktop for Mac]
+
'''Q: Can I use two or three depth sensors with iPi Motion Capture?'''
  
 +
'''A:''' You can use two depth sensors (Kinect/Xtion/Carmine) with iPi Motion Capture (supported in [http://ipisoft.com/software/basic-edition Basic] and [http://ipisoft.com/software/standard-edition Standard] editions). Three depth sensors is supported in version 2 in experimental mode. Using more depth sensors is currently not feasible due to sensors mutual interference.
 +
 +
 +
'''Q: Can I use Kinect 2.0 iPi Motion Capture?'''
 +
 +
'''A:''' Kinect 2 for Xbox is not possible to use, as it does not have any connector for PC (only proprietary connector for Xbox One). We will include support of Kinect 2 for Windows as soon as it is released (expected in summer 2014).
 +
 +
 +
'''Q: Can I mix Kinect with other cameras in multi-camera set-up?'''
 +
 +
'''A:''' You can mix Microsoft Kinect, ASUS Xtion (Live), and PrimeSense Carmine depth sensors. But you cannot mix depth sensors with color cameras. However, for better results, it is strongly recommended to use devices of the same model in multi-camera configuration.
 +
 +
 +
'''Q: Can I use USB cameras of different models in multi-camera set-up?'''
 +
 +
'''A:''' Not recommended. For best results all cameras should be the same model. Moreover, we strongly recommend to use Sony PS Eye camera, as it has much better quality for markerless mocap.
 +
 +
 +
'''Q: Can I use high-resolution cameras to improve tracking quality?'''
 +
 +
'''A:''' No. For our software higher resolution does not give much benefit, but highly increases required data bandwidth. As this is markerless technology, we do not need to track small markers, and 640 x 480 resolution will work as good as HD. For motion capture fps (frames per second) is much more critical parameter for tracking accuracy. [http://en.wikipedia.org/wiki/PlayStation_Eye Sony PS Eye] camera, that allows to record at 60 fps with low distortions, is currently most recommended model.

iPi Studio System Requirements


Q: What is the cost of hardware necessary to use the system?

A: Presuming you already have a PC with DirectX 10-compatible GPU (with Shader Model 4.0 support),

For Express Edition:

  • You will need Kinect sensor, the cost is around $110

For Bacis Edition (4 Sony PS Eye cameras):

  • Sony PS Eye cameras + USB cables, the total cost is around $160
  • Tripods (optional), the cost is around $50 (4 items)

For Bacis Edition (Dual-Kinect configuration):

  • 2 Kinect sensors, the price is around $120 (you need 2 items)
  • Kinect floor stand (optional), the price is around $15 (2 items)

For Standard Edition (5 — 8 Sony PS Eye cameras):

  • Sony PS Eye camras + USB cables, the total cost is around $240 for 6 cameras configuration
  • USB controller, the cost is around $30
  • Tripods (optional), the cost is around $80 (5 — 8 items)
  • (optional) extra HDD for video recording (so that you do not record on your system drive), the cost may be around $50


Q: Is there a version for Mac?

A: To run this software on a Mac you need to install Windows on your Mac using Boot Camp or similar solution.

Kinect Support (All Editions)

Q: What drivers for Kinect are used in iPi Motion Capture?

A: On Windows XP and Vista we use a lightweight solution based on the driver from PrimeSense (psdrv3.sys) to communicate with device via USB. Protocol implementation is our own. On Windows 7 and later we can use either the same solution or Microsoft KinectSDK driver (which is recommended).


Q: Is this driver compatible with OpenNI and Brekel plugin?

A: Yes. If you have already installed PrimeSense's OpenNI drivers for Kinect then there is no need to install drivers again thus you can choose not to install any Kinect drivers during iPi Recorder Installation.

Basic and Standard Editions

Q: Can I use cameras other than Sony PlayStation 3 Eye?

A: Not recommended (although technically possible). Sony PlayStation 3 Eye cameras have multiple advantages.


Q: What if I use expensive professional high-resolution cameras?

A: No. For our software higher resolution does not give much benefit, bit gighly increases required data bandwidth. As this is markerless technology, we do not need to track small markers, and 640 x 480 resolution will work as good as HD. For motion capture fps (frames per second) is much more critical parameter for tracking accuracy. Sony PS Eye camera, that allows to record at 60 fps with low distortions, is currently most recommended model.

How-to

Q: How do I change scene orientation? For example, what if I want my 3D character to stand in the coordinate system origin (0, 0, 0) and face Z-axis direction?

A: Click the "Recenter Coordinate System on Character" button on "Scene" tab, or check the "Recenter coordinate system on character in first frame" option on "Export" tab.
