Re: Ray Traced Spheres

I thought some of you more artistic people would have increased the number of spheres, changed their positions, etc. and rendered a new scene or two. Maybe due to the time it takes to generate each scene that soon would get boring. I love the nULA version with increased grey shades. Very nice, but h...

Re: Ray Traced Spheres

Not sure what happened with the disk image. I created a blank floppy and saved the files into that disk from within the BeebEm emulator.

I have tried loading a few of the files from within BeebEm and it seems fine to load them.

Re: Any short type-ins for unattended Beebs?

Attempt to write a program that draws non-overlapping filled circles onto the screen.

That takes some doing, and gets you thinking too, or try to write a mandelbrot drawing program (slow in BASIC but entertaining nonetheless).

Re: Making reasonable progress with a Sudoku solver

Those changes are superb.

The fact that the MODE 7 version is suitable for a standard Model B is great, and for those with extra RAM the Mode 1 version is so much clearer to see.

Great stuff.

Re: Making reasonable progress with a Sudoku solver

I have a suggestion: The Sudoku grid doesn't make it clear where the borders of the 3x3 grid are, thus making it harder to see the divisions. One way to solve this is to use a solid line for the border of each 3x3 region and a dotted line within to separate each single cell. Another way is to thicke...

Re: Most disappointing conversions from other systems

For me, Atic Atac was one of those that was most disappointing on the Beeb. It just didn't seem right considering that it required a high number of colours and on the Beeb that meant MODE 2 with its fat pixels when compared to the Spectrum version.
