Yesterday, I posted something and then forgot to actually explain the image. I feel bad. Go back to see the full explanation of that sweet picture. But when you finish reading it, come back here because I got a treat for you. This is a 3D drum. There are a few things about this drum, so I want to explain a few things about them before I go on about how I mastered this artwork. Two years ago, I built a drum in my dorm room. I bought a 2'x2'x1" piece of super-ply. I bought nylon cord, brass tubing, a coping saw, and a 16" goatskin drumhead over the internet. With the coping saw, I cut the plywood board into four pieces. I put two pieces away and they are still sitting in my toolbox. The other two would become the drum body. How does a person turn two 1'x1'x1" super-plywood boards into a drum body? Simple, you cut concentric rings out of each of the boards. But the concentric rings are more tightly packed on one of the boards than the other. Then you take the widest ring from the wider-spaced rings board and put it at the top. Then you take the widest ring from the thinner-spaced rings board and put it under. They fit together with an airtight seal. You glue them together. Then you cut more and more concentric rings until you have a drum with the correct height. It's harder than it sounds. A coping saw is the wrong tool for the job. Later, I learned that a band saw could not only do that in five minutes, but it could cut it at an angle so that the drum body would be smooth inside and out. Instead, my drum is layered. That's fine with me. It may create a high noise to sound ratio, but it sure does put out a lot of volume. It can make more noise than a person shouting at the top of their lungs and it projects off buildings and over hills. I know because people have told me so when I drum. I made the goatskin head wrong. You're supposed to soak it for many hours and I soaked it for half an hour. It was nice and rubbery when I took it out, so I thought it would be good. But it wasn't. It's as stiff as a board. It won't make a proper sound. I even analyzed it with my AltSci3D Direct Acqusition for a Physics 207 (Physics of Music) term paper. You can read that paper here.

I just wrote an inspring paragraph about my drum, but IExplore.exe crashed and I lost it. Buy me a new motherboard and I'll write that paragraph over. At least I didn't lose the hour worth of work before it like I've done twenty times in the past two weeks. Anyway, I had a great idea for a Making Of JF page tonight. That is: make a drum and explain my drum stuff. Here's the info on the picture. It's polygon-heavy, but I don't mind. It's a very intensive picture. It has most of what the actual drum has. It's pretty much a technical sketch. In fact, almost a third of the polygons are for polygons of the inside of the drum that you can't see. I made it technical so that I could print it out and it'd be official. So how did I make it? I took a cylinder with 1 stack and 12 slices. It may not have been enough, but I don't care. I made sure that it was exactly 6" wide at the top and that each layer was 1" high. Then I scaled the bottom one by 0.95. Then I extruded 1" and scaled by 0.95 twice (that is 0.95*0.95). Then I extruded and scaled three times. I did that seven times. You can see that there are 9 stacks here. Where are the others? Well I decided that the bottom was small enough so I extruded the top. But I had to scale by the opposite of 0.95. What is 1/0.95? 1.0526315789473684210526315789474. You can't just plug that into MilkShape3D, so I rounded to 1.053. I did that twice on the second time and I was done with the outside of the body. I made the drum one inch thick and extruded the inside the same way. Then I duped the top and made it the drum head. The copper ring was a bit harder. I took a two stack cylinder and scaled the top and bottom. Then I extruded the ends and attached the vertices. It became an almost perfect handmade torus. Then I added the rope as a 6 slice, four stack cylinder. I made one side and duped it, connected it, duped it, rotated it and presto. I messed with the materials and I was done. The whole use of the ring is pretty important. Instead of punching holes in my drumhead, I took one ring and slid it over the head and around the base. Then I folded the drumskin over ring and I placed a second ring on the outside. Then I tied nylon cord from one side to the other. It works wonderfully.

My computer just crashed three more times two of them were 'random' reboots. Whenever I try to do anything cool, it goes splash. I'm gonna quit while I'm behind. Who am I blaming today for my computer problems? I dunno. It might be because I don't have a CPU fan in this computer. It might be that I'm too demanding and it's revolting. Or it might be that I'm using a computer that is long overdue for retirement. But that doesn't explain my previous computer doing the exact same fscking thing and finally dumping it's brain on the floor. sob.

If you're still reading this, you have a treat waiting for you. Check Out my System Shock 2 MFG/story tribute. This webpage has an interface exactly like the System Shock 2 MFD and it has all of the Logs and E-mails. It doesn't have the audio, because it's too large to fit on the webserver and would probably be copyright infringement or some such. How did it happen? Well, I hacked it. You can check the HTML and the javascript and the CSS. It's all really well coded. I got everything from the files on the CD. If you want to hear more about it, check out the whole 2 days I spent on it. All the pictures are very small when compressed with PNG.
