Java. Free to use software to digitize geological cross-sections, and display and edit borehole logs. Geoscience ANALYST [31] Free 3D visualization and communication software for integrated, multi-disciplinary geoscience and mining data and models, which also connects to Python through geoh5py, its open-source API.
In 3D computer graphics, normal mapping, or Dot3 bump mapping, is a texture mapping technique used for faking the lighting of bumps and dents – an implementation of bump mapping. It is used to add details without using more polygons. [1] A common use of this technique is to greatly enhance the appearance and details of a low polygon model by ...
In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the map shape. The environment is projected onto the sides of a cube and stored as six square textures, or unfolded into six regions of a single texture. The cube map is generated by first rendering the scene six times from a viewpoint ...
Bump mapping[1] is a texture mapping technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface, although the ...
Version 1.0 was released in January 2009. [8] In 2013, along with release of version 2.0 the name was officially changed from Quantum GIS to QGIS to avoid confusion as both names had been used in parallel. [9] Written mainly in C++, QGIS makes extensive use of the Qt library. [6] In addition to Qt, required dependencies of QGIS include GEOS and ...
Texture mapping. Mapping a two-dimensional texture onto a 3D model. 1: 3D model without textures. 2: Same model with textures. Texture mapping[1][2][3] is a method for mapping a texture on a computer-generated graphic. "Texture" in this context can be high frequency detail, surface texture, or color.
In seismology. In the context of seismic migration, specularity is defined as the cosine of the angle made by the surface normal vector and the angle bisector of the angle defined by the directions of the incident and diffracted rays. [3] For a purely specular seismic event the value of specularity should be equal to unity, as the angle between ...
