![]() Likewise, we suggest that there is not one overall solution which could be considered suited to all conservation needs and that a careful and objective prior approach to defining the needs is essential as a prelude to choosing the right imaging approach for each chosen cultural heritage object. ![]() ![]() The conclusion of this empiric research suggests that such solutions are indeed practical and within reach, but do not in any way alleviate the users from the necessity of obtaining a high level of proficiency in the use of such technologies. When the filter is complete, click on Close to close the window. Keep the default values and select Apply. Scroll down to the next cascaded window and select Close Holes. Go to Filters and select Remeshing, Simplification, and Reconstruction. For this purpose, we have limited ourselves to such which may be achieved at little or in some cases even at no cost. MeshLab is an open source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes. Now, lets get started by closing up the open areas of the model. The starting hypothesis for this work is that most cultural institutes lack the funding to adopt the high end and expensive solutions available on the market today. In this paper, we have attempted to map, compare and suggest three affordable imaging approaches for the documentation, conservation, maintenance, analysis, and presentation of tangible cultural heritage objects. Apart from simple visualisation purposes, the textured 3D models are now also better suited for on-surface interpretative mapping and the generation of line drawings. In addition, the technique is very useful for low-end 3D viewers, since no additional memory and computing capacity are needed to convey relief details properly. Whether applied to the original 3D surface model or a low-resolution derivative, this newly generated texture does not solely convey the colours in a proper way but also enhances the small-and large-scale spatial and morphological features that are hard or impossible to perceive in the original textured model. When the filter is complete, click on Close to close. The presented approach tries to overcome this switching between objects visualisations by fusing the original colour texture data with a specific depiction of the surface normals. Scroll down to the next cascaded window and select Close Holes. Instead of constantly switching between the textured and untextured version of the 3D surface model, this paper presents a new method to generate a morphology-enhanced colour texture for the 3D polymesh. 1 Answer Sorted by: 2 It seems to me that your boundary is turned towards the exterior of the cylinder, so closing the hole building a patch of triangles would produce several undesired auto-collisions. However, this texture can very often also obscure the underlying geometrical details of the surface, making it very hard to assess the morphological features of the digitised artefact or scene. The fact that such Image-Based Modelling (IBM) approaches are capable of providing a photo-realistic texture along the three-dimensional (3D) digital surface geometry is often considered a unique selling point, certainly for those cases that aim for a visually pleasing result. ![]() Since a few years, structure-from-motion and multi-view stereo pipelines have become omnipresent in the cultural heritage domain. ![]()
