![]() Mirroring this image will give you the Rorschach example above. (Here blackLevel is a parameter that controls how speckly vs blobby the result is - higher values mean more solid black - and contrast controls how sharp the edges are) Then threshold it by taking (sum - blackLevel) * contrast We can make this work by adding a gradient over top (contrast exaggerated here for clarity) The shapes are about correct, but to look like a Rorschach test it should be densest near the middle and thin out toward the edges. If we threshold this directly, we get an image like the one at the right. You can bake tiling noise into a texture and then sum one or more samples from it, changing their offsets/rotations to vary the shapes you get. 1/f noise, often called turbulence, works pretty well. ![]() This is the method that dnk drone.vs.drones suggests in another answer, and it can give results similar to this:Įdit: here's a breakdown of how the noise-based approach works.įirst we start with some noise. Blotter spots, liquid paint drip drop splash and ink splatter. ![]() See inkblot stock video clips All image types Photos Vectors Illustrations Orientation Color People Artists Offset images AI Generated More Sort by Popular Ink drops and splashes. That gets a symmetrical irregular shape, which can be made to change continuously over time if you like, but it won't look quite like ink. 67,345 inkblot stock photos, vectors, and illustrations are available royalty-free. If you don't care about those signature inky shapes, you can also do this with a shader that thresholds two noise patterns scrolling past each other. His goal was to create a reliable and valid tool for diagnosing mental and personality disorders using perceptions of reality. ![]() Hermann Rorschach created it in the early 1920s. Here's an example of the kind of result you can get doing it this way: The Inkblot Test is a general approach to decoding your perception in a projective and open-ended fashion. Render that to a texture with wrap-mode set to mirror, and now you have a symmetrical ink blot you can display without any custom shaders. You might be able to use a particle system to do this scattering) (With a bias toward the seam edge so the middle of the Rorschach test is densest. Then you can randomly select some number of them to position & rotate randomly over one-half the image. To get that authentic inky look, your best bet is probably to assemble a library of images of ink splats, streaks, and dribbles. ![]()
