Hi all. It's been a long time since I wrote to this list. Glad to see the R project well and working.
I am working with a 3D plot similar to this: http://old.nabble.com/file/p26525261/rgl-device.png rgl-device.png The underlying picture is a JPEG image, loaded with the rimage package and coerced to the matrix. Spheres denote control points, collected from this picture and must be situated over the certain points of the image. I display the image with rgl.points. In case of the standard video camera image (704x576) it has to display over 400000 points which is rather slow and memory consuming. How can I put an original JPEG on this plot? Another problem is that the picture is color initially, but was converted to the grayscale. I'd like to preserve colors. Any hints would be appreciated. -- View this message in context: http://old.nabble.com/How-to-display-an-image-on-RGL-plot--tp26525261p26525261.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
