What is LSCM?
LSCM stands for Least Squares Conformal Map and it refers to 2D or 2-dimensional type of map or representation of a 3-dimensional image or shape. In the field of computer graphics and design, the LSCM method basically helps create or convert a complicated 3D shape into 2D image. By means of Least Squares Conformal Mapping, the original colors in the original 3-dimensional image may still be applied to the output 2D image through several steps involving the use of texture mapping and UV mapping techniques.
People that are into computer graphics typically use the LSCM method when trying to create a texture map out of a 3-dimensional mesh involving polygons. The main goal is basically to minimize the image distortion in terms of texture when converting a 3D model image to a 2D texture type of map. 3-dimensional images typically will be viewed as a mesh of polygons when using the LSCM method. These complicated polygons will then be welded and joined at specific parts and joints to indicate which parts correspond to the corners and edges of a specific graphic. Texture mapping will then be applied and this will create the so-called wrapping of the original 3D surface or image. By means of texture wrapping, a 2D image will then result. In this particular sense, the LSCM technique basically involves being able to wrap the original 3D image with a texture layer in order to make it 2-dimensional without having to get rid of al the texture details.
The Least Squares Conformal Map technique is often likened to putting on wallpapers or covers to a certain object with so much details. The wallpapers will basically function to hide some of the details but still retain most of the texture from the original object. In LSCM, converting 3D to 2D also works in the same manner except that manipulation is done electronically.
