OpenCV (Open Source Computer Vision) is a library of programming functions mainly aimed at real-time computer vision, originally developed by an Intel research center and now open source.
TouchDesigner comes pre-installed with OpenCV 3.2, OpenCV and numpy which interface with TouchDesigner's Python 3.5, making it possible for TouchDesigner to access the OpenCV functions directly.
- open TouchDesigner099
- open the Textport with Alt+t
- run following script:
TouchDesigner 64-Bit 099 Build 2017.2620 compile on Fri Feb 17 16:03:29 2017 Python 3.5.1+ (default, Apr 21 2016, 11:06:11) [MSC v.1900 64 bit (AMD64)] python >>> import cv2 python >>> image = cv2.imread(app.samplesFolder+'/Map/Trillium.jpg') python >>> print(image)
- if the output is an array of numbers and no errors, OpenCV is working properly.
