Re: [DIY] Any 3D artists here?

I got interested in woodworking in the 90's and bought all kinds of woodworking equipment. I was using my computer for coming up with plans. At first I was just winging writing a program is basic using drawing commands to come up with a plan for whatever I was trying to design. In those days Basic programming was available on computers. After a few projects I realized how much work I was doing everytime I came up with a new design. Without a design it's all guess work when cutting material. So I went to library and taught myself some of the basic math needed for 3D drawing in a 2D drawing medium. I eventually wrote a program that could draw any design so long as all the design used 90 degree cuts. It uses matrix math which you don't need to concern yourself with if you're just drawing an image to be creative. The result of the matrix math is to create vanishing point perspectives in a 2D medium. With some simple technique it can be recreated using a straight edge to find your lines for the x, y and z perspectives.

This is an example of a single vanishing point:

for rectangular drawings a 2 point vanishing perspective is useful:

I won't go any deeper than that.
I hope that helps a little,

Thanks for the responses Jan, crafty and Ray. I'm interested in creating some sort of 3D-ish mural or some sort of design on an interior wall. I'm not an artist so it can't be anything very difficult.

They do sell some kits. You basically have transfer sheets that you trace the supplied drawing onto the wall and then do a paint-by-number thing. I've also read a few ways that you can transfer your own drawing. One by a projector. The other by scanning into Photoshop, printing it piece by piece, attaching carbon paper then drawing it onto the wall.

I do have a design that I'd like to try but am still open to other things. I'm not exactly sure if this would be considered 3D. I'd like to draw (then paint the lines) this into a corner of a wall (interior corner, not an exterior corner). I imagine this would look normal when viewed at the central angle but look skewed at any other angle. I don't know the technique for drawing it so that the lines are correct going from one wall to the other when looking from afar.

What type of 3-D art? Computer? Sculpting? Videos? Paper Maiche Wall Art? 3-D Quilting?

By slim chance are there any members who know something about creating 3D art?
