Circling a Cube in 3D

By barneyb on August 25, 2009

I put together a simple demo to showcase some of the neat stuff the CFML3D rendering engine is capable of.  The demo isn't much to look at, but what's going on under the hood is pretty cool.

"Wow!", you say, it's wobbly rotating cube with different colored faces.  You'd be wrong.
The cube is stationary, in all [...]

Mazes in 3D

Mazes in 3D

By barneyb on August 25, 2009

After sorting some of my issues with trig (though not all of them), I spun up some simple maze views this morning, based on Ray's maze generator.  Assume we have this maze (straight out of genMaze(10, 10) and into a printing loop like Ray demoed at CFUnited):

3D Rendering with CFML

3D Rendering with CFML

By barneyb on August 24, 2009

As everyone knows, CFML is the perfect language for every sort of programming job.  Including 3D games.  The animation is a little choppy with dynamically generated images having to be streamed down from the server side, but never let technology's shortcomings stand in the way of using your favorite tool.  Unfortunately, I haven't run across [...]

CFUnited 2009

By barneyb on August 15, 2009

First, if you're looking for the goodies from my presentation, go here.
As always, CFUnited was a great conference. First, the location Liz (et al) found was great. Comfy room, lap pool, play pools, plenty of space to hang about, etc. There are advantages to being closer in to DC, but I'd come [...]

I presented CFGroovy: Groovy for the CFML Developer this year at CFUnited.  For the millions of you who wished you could have attended my presentation but were unable to make it, I've graciously made everything available for download.
If you just want the (very thin) slides, they are available in PPT and PDF format.
There is also [...]

More Floating Point Madness

By barneyb on August 4, 2009

Ever the one to fight floating point errors, I thought I'd share my latest troubles.  The context is rendering axis labels for a chart, specifically from 67 to 68, in steps of 0.2.  As you can easily deduce, the desired list has six labels: 67.0, 67.2, 67.4, 67.6, 67.8, and 68.0.  However, ColdFusion might disagree [...]
