Homework Help: Visualization of graphs in three dimention

  1. Apr 3, 2008 #1
    how to visualize three dimentional figures for example quadratic surfaces in three dimention when graph is plotted on two dimentional sheet which is usually the case.

    Look up isometric drawing.

    or, if you are talking about transforming an x,y,z point into a x,y point (ie a vector into pixels on a screen) look up 3d projection and perspective transformation.

    Depending on how fluent you are at reading math, the wikipedia article might be what you need. (Though personally, I rarely find wikipedia good at explaining stuff I don't already know).

    What, exactly, do you mean by "visualization"? A good two dimensional rendering of a 3 dimensional graph should include enough visual information (perspective, etc.) to make the 3 dimensional shape clear. At first I thought you were talking about visualizing a graph when you are only given the formula (say, z= x2+ y2) but, since you say "when graph is plotted on two dimentional sheet which is usually the case", apparently that is not what you are asking.
