    Layer based 3D clipping
    (Institute of Electrical and Electronics Engineers Inc., 2016) Kedia, Y.; Hendre, A.; Jain, S.; Afroz, F.; Koolagudi, S.G.
    In this paper, we propose an unconventional layer based clipping algorithm for 3D regions. In computer graphics, clipping is used to select the required part of a graphical object, cut it out from the object and display it separately. The proposed algorithm is not based on any other algorithm generally used for clipping in computer graphics and has a much better time efficiency than the other clipping algorithms available. The 3D space i.e. a cuboid is clipped w.r.t. a rectangular clipping window. The novelty of the algorithm is that 2D regions are being clipped down to the dimensions of the intersection region and then varied along the depth(z-axis) to get the volume of intersection. The algorithm has been implemented for both unrotated and rotated cuboids. The proposed algorithm can have massive applications in any field that requires layer-wise imaging of 3D spaces such as 3D printing, medical imaging, modelling, etc. given the simplicity of its implementation. © 2015 IEEE.

    Selective cropper for geometrical objects in openflipper
    (Springer Verlag service@springer.de, 2017) Maonica, B.; Das, P.; Ramteke, P.B.; Koolagudi, S.G.
    Computer graphics remains one of the most exciting and rapidly growing computer fields. It includes geometry processing as a major part of it. Every element in Graphics can be processed using different algorithms for acquisition, reconstruction, analysis, manipulation, simulation, and transition of simple, primitive, and complex structures. One such commonly used function is cropping/clipping of geometrical objects. In this paper, an approach has been proposed for cropping a 3D object. This algorithm allows users to crop out selective portions of geometrical objects based on certain constraints like the axis, position, and amount to be cropped. The proposed algorithm has been provided as a plugin to the open-source software OpenFlipper and the results of the crop algorithm have been presented. © Springer Science+Business Media Singapore 2017.
