  2. Vector overlay - Wikipedia

    en.wikipedia.org/wiki/Vector_overlay

    Clip (ArcGIS, QGIS, GRASS, Manifold; Extract Inside in TNTmips): The result includes the portions of polygons of one layer where they intersect the other layer. The outline is the same as the intersection, but the interior only includes the polygons of one layer rather than computing the LCGUs. Non-commutative, non-associative

  3. Clipping (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Clipping_(computer_graphics)

    In this sense, the clip region is the composite of the application-defined "user clip" and the "device clip" enforced by the system's software and hardware implementation. [2] Application software can take advantage of this clip information to save computation time, energy, and memory, avoiding work related to pixels that aren't visible.

  4. Boolean operations on polygons - Wikipedia

    en.wikipedia.org/wiki/Boolean_operations_on_polygons

    Early algorithms for Boolean operations on polygons were based on the use of bitmaps.Using bitmaps in modeling polygon shapes has many drawbacks. One of the drawbacks is that the memory usage can be very large, since the resolution of polygons is proportional to the number of bits used to represent polygons.

  5. Line clipping - Wikipedia

    en.wikipedia.org/wiki/Line_clipping

    In computer graphics, line clipping is the process of removing lines or portions of lines outside an area of interest (a viewport or view volume). Typically, any part of a line which is outside of the viewing area is removed. There are two common algorithms for line clipping: Cohen–Sutherland and Liang–Barsky.

  6. Data model (GIS) - Wikipedia

    en.wikipedia.org/wiki/Data_model_(GIS)

    A volumetric object is reduced to its outer surface, which is represented by a set of polygons (often triangles) that collectively completely enclose a volume. The voxel model is the logical extension of the raster data model, by tessellating three-dimensional space into cubes called voxels (a portmanteau of volume and pixel , the latter being ...

  7. Sutherland–Hodgman algorithm - Wikipedia

    en.wikipedia.org/wiki/Sutherland–Hodgman_algorithm

    Note that if the subject polygon was concave at vertices outside the clipping polygon, the new polygon may have coincident (i.e., overlapping) edges – this is acceptable for rendering, but not for other applications such as computing shadows. All steps for clipping concave polygon 'W' with a 5-sided convex polygon

  8. ArcGIS Pro - Wikipedia

    en.wikipedia.org/wiki/ArcGIS_Pro

    ArcGIS Pro is desktop GIS software developed by Esri, which replaces their ArcMap software generation. [1] The product was announced as part of Esri's ArcGIS 10.3 release, [ 2 ] ArcGIS Pro is notable in having a 64 bit architecture, combined 2-D, 3-D support, ArcGIS Online integration and Python 3 support.

  9. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
