  A Jimbo-Miwa like nonlinear differential equation in (3+1)-dimensions is
developed through a generalized bilinear equation with the generalized bilinear
derivatives. Based on the generalized bilinear forms, two classes of lump
solutions, rationally localized in all directions in the space, and a class of
complex lump type solution are generated from a Maple search of quadratic
polynomial function solution to the proposed Jimbo-Miwa like equation. The
apposite conditions to assurance analyticity and rational localization of the
solutions are offered. Each of the resulting lump solutions hold six free
parameters, two of which are due to the translation invariance of the
Jimbo-Miwa like equations and four of which only require to satisfy the
presented apposite conditions of being lump solutions. We also generate circle
or ellipse shape solutions from the obtained solutions using different
conditions on the lumps solutions. Moreover, figures are given to visualize the
properties of the explicit solutions.
