Processing in action from photo pixel to 3D model in two easy steps See the publication www.ontmoeting.nl Processing visualisation With the free Processing program (Open Source) for Win / Mac computers everyone is able to perform quite complex operations in a view counts. Processing is based on the higher level Java, which is performing very well. Processing has a good and relative simple interface and UI. You get thousands of examples on their website and on the openprocessing website aswell. And it is very easy to follow via the step by step tutorials to get started very fast. the Processing manual (Dutch) An Processing example with a bit map as starting point to 3D We start off with a simple photo of the Zaan in the Netherlands (100 x 100 pixels). The photo is read into an Array in Processing and the color of the individual pixels is put into that Array. In the active void draw () the pixels get a new form for instance a surface, an box or a sphere. The picture as the starting point We use every pixel in the picture to save the individual colors in a Array. One of the many possible outputs of Processing of the same picture. With the use of boxes. You can see the above photo from this one. Some parts of the photo share the same density (one surface) Another picture, the centrum of Almere Stad the Netherlands Here we see the picture of Almere in full glory in cubes. Picture of a text -> Processing -> DXF -> SketchUp Pro -> Artlantis This is the chain of the next example. Import a rel. smal photo with a text on it. Remove in Processing all background and print in cubes or sphere the remaining text in full glory in 3D on the Processing screen. We start with a picture of the text frase " Uitgeverij Ontmoeting". the background is white, the text is red. Combination on the left 3D spheres, right de script in Processing. The used text pixels are put together with two surfaces and corresponding lines to connect. Imported DXF file form Processing to SketchUpPro. Alle cubes are outlines. With the use of Ruby script "Make faces" we managed to put all the faces on each cube. The text of the original photo via Processing -> DXF -> SketchUp Pro -> Artlantis. With this method it is possible to make a 3D model of a simple photo, filter out everything that's not needed and bring in a relief with the Z-axes in 3D. See everything in 3D in Processing. When you press the keyboard 'r' everything in the program will be exported to the wellknown DXF file format. From there we make surfaces with the Ruby script in SketchUp Pro and the end point could be photo's of the 3D model. With a rendering program for instance Artlantis Studio we can color the cubes as needed. info: www.ontmoeting.nl To the Top - - See also this Visualisation page- - Zonnebloem / Sunflower WWW.DESIGNCITY.3DONTWERPEN.NL © Alfazet, Huizen
