Step 1: I-A) Creating a Generic 3D Pumpkin

(For each step there is a corresponding picture)
1) Create a new sketch on the x-y-plane and draw what is shown in image 1
2) Delete all but the lines as shown in image 2 and click 'finish sketch'
3) Click the revolve button and select the previously drawn shape for the profile, the y-axis for the axis, and 20 degrees for the angel, and click OK
4) Click the fillet button, select the two curved edges of the previously revolved shape, and indicate a radius of .5 or less before clicking Ok
5)Click the Circular pattern button, select the entire shape, make sure you select the fillets as well, for the feature and the y-axis for the rotation axis before clicking Ok (Note this may take some time to render and may give the dreaded not responding error and a white screen but do not worry- it is just thinking and may take about 10 minutes)
6) Click the 'Appearance' button ( it looks a pie with different colors for each slice... think of all the flavors) before selecting the entire shape and selecting the 'smooth- light orange' color to make it look more like a pumpkin
7) Next select, under the Plane tab, the 'Offset from plane' button and choose the x-z plane and an offset of 8 inches
8) Create a new sketch on the newly made plane and use the spline tool to create a base for the stem
9) Create a new plane with the 'Offset from plane' button again and choose the x-y plane and an offset of 4 inches
10) Copy the sketch from step 8 and paste it into a new sketch on the recently made plane
11) Click the 'move' button and select the pasted sketch and use the base point button on the origin to move the pasted sketch along the y-axis into a reasonable position above the pumpkin
12) Select the 'loft' button and choose the closed shapes from the sketches created in steps 8 and 9-11 before clicking on the conditions tab and selecting direction condition for both options as shown
13) Again select the 'Appearance' button (remember the tasty multi-flavored pie button) and select all parts of the loft created in step 12 and select 'dark olive' as the color
14) Congratulations you have made a 3D pumpkin! (Make sure to save)

Step 2: I-B) Virtually Carving a Pumpkin

1) Open the generic pumpkin file
2) Select, under the Plane tab, the 'Offset from plane' button and choose the x-y plane and an offset of 14 inches
3) Draw face you are attempting to the best of your abilities
4) Click on the 'Extrude' button, select cut, and all the closed sketches that make up the face, indicate a extrude distance of 6, and click OK
5) Right click circular ‘patten1’ and select suppress features before creating a new sketch on one of the flat faces
6) draw the shown closed sketch and revolve it around the y-axis
7) Select the appearance button and all gray faces on your pumpkin before selecting orange to make it all colored and 'Saving as' the face name
8) Open a new standard.ipt part, click the derive button, select the face name and using the scale option change its size to some value between (.7 and 1.5)
9) Repeat for all other faces
10) Great! You can now say that you have successfully virtually carved (a) pumpkin(s)

Step 3: I-C) Creating the Body Parts

1) Open the generic pumpkin file and delete the loft (stem) and save it as 'body'
2) Create a new standard.ipt part, click the derive button, and select the previously made 'body' part
3) Under the scale option indicate 1.1 and click OK
4) Select, under the Plane tab, the 'Offset from plane' button and choose the x-y plane and an offset of (-12*sqrt(2)) inches
5) On that plane create a new sketch and draw a circle as shown with a diameter of 3 inches
6) Select, under the Plane tab, the 'Offset from plane' button and choose the x-y plane and an offset of -36 inches
7) On that plane draw another circle, 12 up along the y-axis, with a diameter of 2.5 inches
8) Click the 'loft' button, select the circles drawn ins steps 5 and 7 before clicking OK
9) Click the 'Mirror button, select the loft created in step 8 as the feature and the x-y plane as the mirror line before clicking OK
10) Click the Appearance button, select both the original loft and the mirror and choose Natural maple
11) 'Save as' this part as 'torso'
12) Repeat step 2
13) Choose a scale factor of 1.2 and 'Save as" the part as 'Legs'

Step 4: I-D) Staging the Scene

(Note there is a picture for each step)
1) Create a new standard.ipt part, select the cylinder option, under the 'box' button, choose a diameter of 12 feet, and a height of 1 inch
2) Create a sketch on the top face of that cylinder and draw the shown sketch with the ark tool
3) Extrude the sketch from step 2 to 20 feet
4) Click on the appearance browser, select the extrusion created in step 3 and select 'black'
5) Then select the cylinder created in step 1, with the appearance browser still up and select 'dark olive', and save as 'ground'
6) Now Create a new assembly and place the 'crazy pumpkin' head, 'torso', 'legs', and 'ground' parts
7) Under the 'Axis' tab, select 'Through revolved face or feature' and one of the placed parts for each of the placed parts
8) Using the constrain button select the newly made axis so they all now have a common axis and click OK
9) Use the place button again to place 'legs', 'torso', 'shocked pumpkin', 'Decapitated pumpkin', 'Surprised pumpkin', 'Alien pumpkin', and 'Terrified, crying, pumpkin
10) Arrange all but the decapitated pumpkin, legs, and torso in a semicircle behind the crazy pumpkin on the ground
11) Arrange the torso and legs in front of the pumpkin on the ground
12) Arrange the Decapitated pumpkin head at the end of one of the crazy pumpkin’s arms
13) Make sure everything looks ok
14) (optional: for fun) render using the shown settings (note this may take a long time on the best quality)
15) SAVE!
16) Congratulations you can now say that you staged a murder, note it may not be wise to tell the cops this without explaining the details first.

Step 5: II-A) Fleeing the Scene of the Crime, Importing Into 3Ds Max

1) Open 3Ds Max
2) Click the 'open file' button
3) Under the drop down menu for file type select 'All files (*.*)'
4) Select your scene and click open
5) In the pop-up box that appears, under import as, click the Meshes option

Step 6: II-B) Shedding Light on the Crime Scene, Placing the Lights

1) On the right-hand panel select the lights button (it looks like a desk light)
2) Select Omni
3) Make your options look like those shown in the picture for this step
4) Place the lights over each of the soon to be jack o' lanterns in the top left view-frame
5) Move the lights so that they are now inside of the pumpkin faces by selecting the lights in the bottom left view-frame and dragging it into place
6) Create a Skylight and drag it into position above the scene

Step 7: II-C) Rendering the Results for Bragging Purposes

Now the current view looks a little cartoonish so let’s make it look more professional
1) Click on the 'Render setup' button and scroll all the way to the bottom of the pop-up box that appears and expand the Assign render tab
2) Under the 'Production' drop-down menu select 'NVIDIA mental ray'
3) Click render and see the results
4) Arrange the scene to a view that you like and adjust the quality options to your liking and click render (Note with everything on highest quality it took me four hours to render with an above average laptop)

Step 8: II-D) From 2D to 3D With Two 2D Renderings

1) On the right panel select the video camera option
2) Select 'Target'
3) Place two cameras as shown (Make sure they are not too far apart and that you can see the majority of all your pumpkins and are at the same height and net distance from the scene)
4) Click and hold the right mouse button over the right-most of the cameras in the bottom right hand view-port and select 'Select view to selected camera'
5) Click and hold the right mouse button over the left-most of the cameras in the bottom left hand view-port and select 'Select view to selected camera'
6) Make sure both scenes are both in realistic mode with shadows enabled
7) Render the bottom right view-port and save the rendered image before doing the same to the bottom left view-port
8) Open both of the rendered images and place them side by side, as shown, and print screen
9) Crop out all but the two pictures with the program of your choice
10) While looking at the cropped picture cross your eyes until the two images overlap and you should see a 3D image (note it may look blurry at first but if you stare at it for a while you will soon see detail, also it may help to back away from the picture at first
11) Congratulations you have successfully created a 3D viewable image!

Step 9: Acknowledgements

I would love to claim that I came up with this idea all on my own but I must admit that I did search Google for ideas, here is a list of influential sources:

In addition, this this is my first instructables so please leave comments as to how I might improve next time.
Awesome! How long did it take u to do that??
The Inventor part took around six hours of fiddling to get everything right and the 3Ds Max part took about two hours because it was the first time that I used that program. <br>However, if you follow the steps shown it should take less than three hours, excluding rendering time, which may take a while.
