Now, letвЂ™s look at the code: The Hash Function: In this way, if a key in the map has more than one item in the array, then those images are duplicates.ДЇrom here, you could do whatever you want with the duplicates.

Maintain a Map with the hash as the key and the array of image paths as the values. I don't think there's any node that automatically blurs a texture (it would be nice, it would allow to easily tweak a height map from any picture), that said Decoded explains here how you can do it with this node setup: Plug your Texture Coordinate into a Noise Texture with Roughness at 1 and high Detail and Distortion, then plug into.

Generate unique fingerprints for images using the perceptual hashing technique.

Read all files in the directory one by one.

The first Image Map Shader will handle displacement. One for elevation, which will create surface displacement. The process that we will be following is simple: WeвЂ™ll start by creating three Image Map shaders in TerragenвЂ™s node editor: One for terrain, to map the surface image to the surface of the planet. So, without further ado, letвЂ™s look at how we could compare images and detect duplicates using Node.JS by applying perceptual hashing (pHash) and using the Map data structure. Now when you move slider left or right you can darken or brighten hdri image preview.

Click OK and in the bottom left corner switch little slider to 32-bit Exposure. If not, you will learn a neat trick with Node.JS that you could use when a situation demands it. As we are not working with OpenEXR layers choose whatever option and click OK. If the above situation sounds familiar, then this article is essential for you. But then, a few hours into it, you are reading some OpenCV documentation and articles and you didnвЂ™t know how you ended up there and worse, you realize, the rabbit hole is endless.

Third-party offerings are available to help, such as pre-made scenes and objects along with tutorials from New World Digital Art and Geekatplay.Did you ever find yourself in a situation where you had a directory full of images and might have potential duplicates? To look through each image and mark duplicates will be a waste of your time, and so, you wanted to automate it with a script. But for this we can forgive Planetside, as they are a very small company and focus their resources mainly on development.

The bad news is, youвЂ™re going to have to rely mainly on other users to determine the best settings and how to use them, as documentation for Terragen has always been sparse and runs a bit behind each release. The image below shows the blur with a low value for the Scale. Scale: Defines the scale of the blur to apply. Intensity: Defines the intensity of the blur to apply. Slope down: The blur has the effect of digging into the terrain.

Slope up: The blur has the effect of enlarging the terrain. Other tabs handle the overall Terrain attributes, Shaders (effects applied to terrains to create dirt, grass, snow, etc.), bodies of Water, the Atmosphere (clouds, haze, etc.), Lighting (placement of the sun and other lights), Cameras (for taking вЂњphotosвЂќ of your scene, either still or animated), Renderers (settings for the size and quality of the finished image) and the Node Network (an advanced form of connecting and managing the attributes of your project, and no, I havenвЂ™t used it yetвЂ¦).Д®ach tab has its own very detailed sub-settings that give you incredible control over your scene and the items in it. Contour: The blur follows the contours of the terrain. Tabs include a Library collection of scenes and objects, where you can import pre-made scenes and various 3D models and combine them to make your illustrations (thatвЂ™s how I did the renders shown here). But I found that if you break Terragen 4 down piece by piece and watch some online tutorials, youвЂ™ll get going pretty quickly.

However, fear not: with a small amount of nodes grouped into a Node Group, we can create our own Blur Node. A feature, Which unfortunately doesnвЂ™t come with Blender by default.

The Classic version (0.9, circa-2005) was a little more approachable and I did some decent work with it. The ability to blur textures and texture masks is a very convenient, and some would say essential, feature in visual software (often called Gaussian Blur). Looking at the screenshot above, itвЂ™s easy to become immediately intimidated with Terragen, with its many tabs and sliders, and even nodes! For a long time I wasnвЂ™t sure exactly how it worked and what to do with it, since IвЂ™m a right-brained creative type and enjoy simple and intuitive interfaces.
