1. First go to Start > All Programs > Softimage Products > Softimage XSI 4.2 > XSI Advanced




                                                                                        Softimage Tutorial
2. Next you need to create a cylinder. Go to Get > Primitive > Polygon Mesh > Cylinder




                                                                                         Softimage Tutorial
3. A box will come up and in that box change the radius to 0.3 and change the height to 12. and press enter




                                                                                                    Softimage Tutorial
4. Now you need to get a grid. Go to Get > Primitive > Polygon Mesh > Grid




                                                                             Softimage Tutorial
5. Now we need to rotate the grid. So on the right hand of the screen click the button with an “r” on it and then three buttons will
             light up. Click on the button with an “x” on it and in the box next to it type in 90. Then hit “Enter”.




                                                                                                                  Softimage Tutorial
  6. Now if you click on the ”T” button you can move selected objects. In this case you will be able to move the grid. Now move
 the grid so that it lines up with the pole and looks like a flag on a post Look in your Top view and make sure your flag overlaps
   your pole just a little bit The top view is the top left view. Once you have that done you need to stretch the flag out so that it
looks more like a flag. So on the right hand side above the rotate button you just used there is a button with an “S” on it. Click it
    and select the button with an “X” on it that is right beside the “S”. Stretch it on the x-axis (the red box) by left clicking and
                                                                  dragging.




                                                                                                                   Softimage Tutorial
7. Now we will make the grid look like a flag. So in the top left hand corner there is a button that says “Model”. Click on that and
       go to “Render”. If it doesn’t say “Model”, it might say “Simulate”, or “Animate”. Click on that and go to “Render”.




                                                                                                                  Softimage Tutorial
8. Now go to Get > Material > Lambert. This will add texture to your flag.




                                                                             Softimage Tutorial
9. Now you will add an image to the flag, by going to Get > Texture > Image and a box with a lot of colors will come up. In that
  box there is a drop down menu under the words “Texture Projection” and next to the drop down menu there will be a button
                                       called “New”. Click that and click on “Planar XZ”




                                                                                                              Softimage Tutorial
10. Now in the drop down menu at the top of that box under “Image” (you might need to scroll up). Click the button next to it
 that says new > new from file a box will pop up. Go to Z:BieschkeA/Flag,jpg, double click on the Flag.jpg file. Or you can
                                             choose a picture of your choice.




                                                                                                             Softimage Tutorial
11. To see your flag, place your mouse in the Camera View. While holding down the “Q” key, click, drag and make a box in
Camera View. This will create a quick render region and will show you what the flag looks like. To get rid of the quick render
region hold the “Q” button and just click outside of your current render region.




                                                                                                                Softimage Tutorial
12. You can rotate around your flag by holding the “S” key and right clicking and dragging your mouse.




                                                                                                 Softimage Tutorial

                                                           “Simulate”.




                                                                                                                Softimage Tutorial

                 the button with a “T” on it in the right side. So just move your gravity force away from the pole.




                                                                                                            Softimage Tutorial
18. Now you will add wind to your scene. So go to Get > Force > Wind. Now move your wind force to the left of the pole.
                                       Make sure it’s pointing towards your flag.




                                                                                                         Softimage Tutorial

20. Now select your gravity and press, “enter” This will bring up the property box for your gravity. You can change the amplitude
 of your gravity. The higher the amplitude number, the more gravity will be in the scene, You can also change the amplitude of
 the wind by selecting the wind and pressing enter. The higher the amplitude number of the wind the more wind there will be in
                    the scene. You can change the amplitude of the wind and of the gravity to what you want.




                                                                                                               Softimage Tutorial
