 Author Comment/Response McLaine 08/25/09 09:49am Hello, I've currently got a problem that drives me crazy. My starting point is that I want to visualize three conditions for the variables w1,w2,w3. These are: 1. w3 <= -20/3 + 10/3 * w1 - w2 2. w3 <= -40/3 - w1 + 10/3 * w2 3. w3 >= 6 + 0.3 w1 + 0.3 w2 I'm looking for a way to plot the object that results when simultaneously considering all of these conditions. I started with defining each condition as an equation. Then, I plotted each resulting plane separately and all at once. The source code looks like this: L1 := -(20/3) + (10/3)*w1 - w2 L2 := -(40/3) - w1 + (10/3)*w2 L3 := 6 + 0.3 w1 + 0.3 w2 Plot3D[L1, {w1, 0, 10}, {w2, 0, 14}] Plot3D[L2, {w1, 0, 10}, {w2, 0, 14}] Plot3D[L3, {w1, 0, 10}, {w2, 0, 14}] Plot3D[{L1,L2,L3}, {w1, 0, 10}, {w2, 0, 14}] I attached the last figure below. My problem is that this plot is not what I am looking for :-) The object I want to be plotted is only indirectly defined by the three planes. It consists of the points below the horizontal plane (condition 3) and above the other two (conditions 1 and 2). Is there any way to visualize this object more directly? Thanks.
