The alpha channel can be thought of as a measure of transparency. The number 4 refers to the addition of an alpha channel (the first 3 are red, blue and green) In the next step, ROWS is the number of rows, which you should read from your image, and COLS is the number of columns of your image. Now, convert it to 32-bit floating point: My wave name was image.jpg, and didn't work at first, because of the period.) Let's say you named it "imagewave" using the data browser. The jpg needs to be manipulated in order to use it as a color wave.įirst, rename your imported image to a non-liberal name (no periods. I am posing this here to help anyone else in a similar situation. for taking me through the first few steps to get this going: I watched the texture video tutorial and am frankly lost, and not really sure if it would apply to what I am trying to do. OK, that was a long story, but I hope there is a short answer. I can't use this for print, however, because the image quality is less than ideal (the texture is severely downsampled and the geometry cannot be defined by more than 250,000 verticies). ![]() I have done a mock-up of what the resulting image should look like using the interactive surface map imageJ plugin, where you can load a depth map, and then "load texture", to load the texture, and it makes a 3d composite image with the texture properly applied to the surface. However, I can't seem to find an option to apply my texture image (color values) to the gizmo plot. I can create a surface plot of in Igor, and color the image according to the Z value. The color value is stored in a jpeg that I have imported to Igor, of the same dimensions. The height is stored in a 2d wave (matrix), the dimensions of which correspond to the x,y dimensions of the image. For each (x,y) point, I have a height value (z) and a color value. I have already stitched all of the images together, and as a result, I have about 17 million points, but for the sake of trying things out with limited computer resources, I have resampled it to about 4 million points. ![]() I am trying to make a nice 3d composite of a collage of 3d microscope images (surface maps). I'm hoping that someone here can help me finish my plot. I've been using Igor for years, but only recently started to make 3d images with gizmo. Wide-Angle Neutron Spin Echo Spectroscopy.
