Free : How to Sketch a Line in Three Dimension or in Space?

In order to draw the axes for three dimension, we look at the Cardinal direction and we draw the vertical axis which is called the Z-axis in the North direction. Then we draw the X-axis in the South West direction, the Y-axis in the South East direction,the negative X-axis in the North East direction, and the negative Y-axis in the North West direction.

Step 2

We would like to plot two points, the point P at coordinates (5,7,3) and the point Q at coordinates (-2,3,4). We are then going to draw a line through these two points.To do so, we go five units along the X-axis and then draw a line parallel to Y-axis that intersect the X-axis at x=5.

Step 3

We would like to plot the point P at coordinates (5,7,3).We go seven units along the Y-axis and then draw a line parallel to X-axis that intersect the Y-axis at y=7. Please click on the image for better understanding.

Step 4

We now draw a line from the origin of the axes O, that has coordinate (0,0,0) to the point where both the line X=5 and the line Y=7 intersect. That point R has the coordinate (5,7,0).
We now draw a vertical line from the point (5,7,0) parallel to the Z-axis.
We go to the Z-axis and at z=3, draw a line parallel to the line that connects the point (0,0,0) and (5,7,0). Wherever that line intersects, the vertical line from the point (5,7,0) that is parallel to the Z-axis, that intersection is our desired point, P.

Step 5

In order to have a better understanding, we can visualize a point in three dimension as the corner of a box. If we look at the image for this step #5 we see a corner of the box defined by the point P(5,7,3). Please click on the image for better understanding.

Step 6

Similarly, To plot the point Q at coordinates (-2,3,4), We follow the instructions given in the previous Steps. That is we are going to draw a line at x= -2 parallel to the Y-axis, Then we draw a line at Y=3 parallel to the X-axis the point S where the line X=-2 and the line Y=3 intersect has coordinate (-2,3,0). Please click on the image for better understanding.

Step 7

Now, from the point S(-2,3,0) we draw a vertical line parallel to the Z-axis that is four units in length. The point Q is (-2,3,4). Please click on the image for better understanding.

free 3D Design Magazine Data Conversion Article

3D Design Magazine's "In The Lab", features Okino's PolyTrans 3D data translation product. This is the second article written by Brendon Perkins on our PolyTrans software; the first review can be found here.

As an introduction to 3D data conversion, Mr. Perkins writes:

"If you work in 3D, chances are you rely on multiple software applications to complete your work - modeling, animation, rendering, image processing, and video editing apps; perhaps more than one of each. So it's interesting to note that no file format standard is accepted throughout the industry for exchanging 3D data among applications. On the other hand, it's not likely that one will emerge. Tool developers strive to create marketable advantages for their tools, and these advantages are reflected in, or implemented as, mutually incompatible file formats.

In lieu of a standard exchange format, most applications provide a limited set of import and export routines. But these routines usually don't provide a complete solution. In many cases, they don't account for intricate differences between formats that might help optimize models for the target application. Furthermore, they rarely deal with anything other than geometry. If you need a complete conversion that includes texture maps, animation paths, and the like, the usual import/export routines fall short.

The single fact is that converting between 3D file formats isn't a straightforward task, and vendors have little incentive to develop top-notch conversion utilities. Consequently, there's room in the market for specialized file format conversion applications." More

All free : The Most Realistic Virtual Reality Room in the World and HSL's Thoughts on the Future of Combining Telepresence and Virtual Reality

Owa State University has rolled out a six-sided Virtual Reality Room with 2Xs the number of pixels than any other virtual reality room in the world. The full press release can be found Here and my excerpts and thoughts on the future of combining telepresence and virtual reality are below.

Newswise -- More than $4 million in equipment upgrades will shine 100 million pixels on Iowa State University's six-sided virtual reality room.

That's twice the number of pixels lighting up any virtual reality room in the world and 16 times the pixels now projected on Iowa State's C6, a 10-foot by 10-foot virtual reality room that surrounds users with computer-generated 3-D images. That means the C6 will produce virtual reality at the world's highest resolution.

Iowa State's C6 opened in June 2000 as the country's first six-sided virtual reality room designed to immerse users in images and sound. The graphics and projection technology that made such immersion possible hasn't been updated since the C6 opened. More
