In this Instructable I'll show you how to make a glass of wine with Blender, a free 3d modeling program. You can get it here.Here's a picture of the final project:
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: First Step: Add a Plane
Open Blender and delete the cube that's there by default(it's already selected, then just press delete).A window will appear, saying"OK?Erase selected object".Press Enter. Now you will need to add a plane.
In the "Add" menu, click on "Mesh->Plane".
Step 2: Second Step: Modify It in Edit Mode
First you need to go in edit mode. For this, do as shown in the picture, or press Tab. Then press 7 on the numpad to switch to upper view. Then, while holding shift, right-click on a point. Then press delete.
In the menu that appears, click "vertices".
Don't worry, three points disappeared , but the only one you need is the remaining one. Move this point to one square to the right from the center:right-click on it, then move it with the red and green arrows while holding ctrl.
Step 3: Third Step: Give Your Glass Its Shape
Now shift to front view by pressing 1 on the numpad. Now we're gonna use the "Extrude" tool. With your point selected, press E. A new point wil appear, linked to the previous one. Move it one square to the left. To do this, move your mouse to the left while holding ctrl. Then press E again, and move the new point one square upper, then press E again and move the new point one square to the right, then press E one last time and move the new point two squares upper. If you did it correctly, it should look like this(if the arrows aren't there and the lines aren't yellow, it doesn't matter):
Step 4: Fourth Step: Correct It
First move the two points on the left a little bit on the right with the red arrow. To select them, first press a so that no point is selected anymore, then press b and move the cursor near the upper one, then while holding the left button of your mouse move it so that it makes a rectangle around the two points. Then move them with the red arrow. Don't hold ctrl while doing this, you don't want your points to be at the same level as the others. Once you've done this, you can use "spin" on your glass.
Step 5: Fifth Step:spin It!
Now you should have, in the area shown in the image, a button with "spin" written on it. If not, press F9 and it will appear. Under the button is written "degr:90.00". Click on it(between":" and the number) and type 360. Then press Enter.After this, press A once or twice( twice if there are points selected and once if not), press 7 to switch to upper view, click the spin button and voila! You're(almost) done. There are just a few more things to do:
-press A twice
-press w, and in the menu that appears, click on "remove doubles". A litte window should pop up saying "removed 5 vertices". Click on it to close it.
-switch to object mode(do as shown on the first picture).
If you don't know how I got the view for the second picture, push the button in the middle of your mouse and move your mouse while holding it. You can also zoom in and zoom out if you scroll forward or backwards.
Step 6: Sixth(and Final)step: Improve It and Finish It
In this step you will make your glass more beautiful, and even translucent. First you will apply a "subsurf" modifier to your glass. To do this, you must click the "add modifier" button and choose "subsurf" in the menu that pops up. Now, under the "add modifier" menu is written "subsurf", and under it "catmull-clark", and under it, "levels". Set this value to 2 if you've got a not so powerful computer and to 4 or more if you've got a better one( not too big though, after 5 you don't even notice it anymore). Set the value under it to that it is the same as the previous one. Once you're done, click on the "set smooth" button (it's shown on the second picture).
Once you've done this, press F5 to switch to "Shading". The lowest part of your screen should be overall grey except for a button on which is written "Add new", under "link to object". Click on it.
Now some columns will appear, labeled "preview", "material", "ramps", etc. If it isn't already selected(=in a lighter grey than the others) select it by clicking on its name. Then click the "ray transp" button and increase the value of "fresnel"(set it to 1 or a bit more). Then you will use the "material" column. There should be a grey rectangle with "col" written next to it. Click on it. The window that appears allows you to choose a new color for the glass. Well then, it's time to render it. Press F10, then press the "Render" button(it's quite big, I won't put a screenshot because I guess you won't miss it). A window will pop up an soon, your awesome glass of wine will appear. To save it, press F3 and select the folder you want it to be put in(you have to type the whole way to the folder, I know that's annoying).
Congratulations! You've made an awesome glass of wine with Blender!If you want to see a few more things I did with blender, you can go there. If you want an instructable on the airship or the steam machine(or something else), you just have to ask, but it will take some time to make.You can tell me what you think of my glass in the comments and post pictures of yours or other stuff you made.
