3DCollective – Photogrammetry Pack 01

If we want to create 3D models as realistic as possible, instead of using polygonal modeling techniques or digital sculpture, we can resort to several methods of “scanning” surfaces and textures such as photogrammetry, using hundreds of photographs of the same object taken from different angles to reconstruct the geometry of a complex model using specialized software. One of the advantages of photogrammetry, compared to other scanning methods, is that we can simultaneously scan the geometry and color of our object to create a photorealistic ready to use model.

To produce a single 3D model with millions of polygons and accurate linear albedo, we use high resolution cameras (50MP +) and more than 200 photographs per object under controlled lighting conditions. Given the large number of initial polygons, it is necessary to adapt them for use in real projects. Through retopology we reduce the polygonal load of 3D models and create PBR textures of 4K and 2K.

The result is excellent, but this method requires very expensive specialized equipment (high resolution camera, studio lights, software, etc.) and it takes a long time to produce a single finished model (scanning, geometry creation, retopology, texture baking, materials , etc). With this pack you can enjoy 76 models of fruits and vegetables and 41 high quality “Sets”, ready to use in your scenes without having to invest the time and money necessary to capture them yourself.

SOFTWARE REQUIREMENTS: 3D Studio MAX 2014 or superior and V-Ray 3.5 o superior

HIgh resolution Photogrammetry camera is excellent for capturing three-dimensional models with lots of geometric details, but to be able to use these models efficiently it is necessary to transform the scanned model into a lower polygonal resolution model and transfer the high frequency details of the model to a normal map. All models of this library are optimized to reduce their polygonal load and have normal 4K and 2K maps, which are thought to be used in both personal and professional projects.

All of the PBR materials in this pack are designed for Vray 3.5 or higher in order to take advantage of the “Glossy Fresnel” option of the render engine that gives you the best PBR results in the most effective way. The result in previous versions of VRay may not be the same as the images in the catalog.
