Hi JP, I don't know much about light modeling. If you need more information on the topic you should ask on the discourse forum (where users with more knowledge might answer).

Hello JP, You might want to ask your questions on the forum ( https://fspm.discourse.group/ ) where more users will be available to help you. The rules: ==> and ==>> are indeed different. Both are rewriting rule, meaning they replace the matched pattern on the left hand side with the produced statement on the right hand side. To simplify: * The first one is a replacement following the L System idea. The edges in and out of the pattern to replace are linked to the produced subgraph. * The second one...

Hi, For the "Reference": When you import an object in the "object explorer" (the object panel), you can create references to that object with "new Reference("name.file");". You can always use the "Add" option, it copy the file within your project. Then, by default the reference is only resolving an "instance" of the object (not the x3d nodes themselves). You can however get the nodes behind the reference by using: {Reference r = new Reference("name.file");} [A ==> r.resolveNode()] Be careful however,...

Hello, Could you give me more detail on what is working (and not) with the plugin manager? The Pointcould importer plugin should be accessible from there. Do you see any other plugins? Otherwise, if you download the plugin from gitlab. You need to see if it is already compiled or not. If you have java classes, it needs to be compiled. If you have a .jar you can use it. (download the jar there https://gitlab.com/grogra/groimp-plugins/Pointcloud-Importer/-/packages/24921990 at the bottom of the page.)...

Hi, The objects imported from an OBJ file are added as one MeshNode in groimp. To map the objects in a file to groimp primitive objects you can either use a file format that support this mapping (e.g. x3d or gltf), or do the mapping manually (which i do not recommend). If you need to see each triangle of your mesh as a separate groimp node you can also use the ply importer from the PointCloud-Importer plugin (https://gitlab.com/grogra/groimp-plugins/Pointcloud-Importer). I don't know mush about the...

Hi, Advanced object manipulations can be done through XL queries. Usually done in an RGG environment. E.g. this query print the surface area of all Spheres in your graph: [x:Sphere::>println( x.getSurfaceArea());] . You can find more documentation on how to use them in the documentation: http://wiki.grogra.de
