Is there a trick to take an isometric image of cubes - that can be thought of as a set of equidistant points, triangles or planes - and in a trivial fashion create a vanishing point -type perspective "distortion" on the cubes? Aka linear perspective, 1-3 vanishin points.
I am guessing this could be also achieved by "scaling down" the y axis proportional to the point's distance along x axis when calculating the points of the triangles.
Note: Im not a mathematician, terminology may not be correct.
Example isometric cube image ;)
