Morphic 3 defensive disclosure
 
|
Hi Folks,
Big news! The first defensive disclosure about Morphic 3 has been accepted and published at http://www.defensivepublications.org/publications/prefiltering-antialiasing-for-general-vector-graphics and http://ip.com/IPCOM/000232657 .. Morphic 3 is described at http://www.jvuletich.org/Morphic3/Morphic3-201006.html This paves the way for releasing all the code, as no one will be able to patent it. Cheers, Juan Vuletich |

Outstanding! Thanks for sharing this. I encourage everyone to read the paper. It is interesting and very readable dispite the technical nature of the subject. Dave |

The first open source thing I ever wrote was a graphics library for devices like that. It was for PC-AT unix, which at the time had no graphics capability whatsoever. I think that I had some sort of fancy third party graphics card that emulated Hercules, CGA, and EGA graphics, and I also had an Epson dot matrix printer, which accounts for the hardcopy device support.

I am guessing that this probably does not get a lot of use nowadays ;-) Dave |

Hi Folks,
Thanks everyone for the nice comments. (below) Quoting tim Rowledge <[hidden email]>: > > On 03-12-2013, at 6:23 PM, J.

I wonder how well we could make it work on a > Pi. There’s a quite nice gpu wrapped around the ARM... I did some experiments with a C program I built from the Slang in the M3 plugin. And compiled sample programs I found online, using Cairo and AGG. This was done for a guy who at some point wanted to build an engine for web games to compete with Flash. The program just kept drawing the tiger svg sample, counting FPS. If I remember correctly, AGG was about 5 time faster than Cairo and 2 times faster than M3. This also means that my technique was about 2.5 times faster than Cairo. All this using a C regular compiler on a Core 2 Duo. No GPU at all. So, I guess it could be "fast enough" for most uses. But it uses float arithmetic all over the place, and I guess the code would need to be adapted to use fixed point or whatever the GPU can provide. There's a lot of fun to be had while doing that. > tim > -- > tim Rowledge; [hidden email]; http://www.rowledge.org/tim > An elephant is a mouse with an operating system. :) Cheers, Juan Vuletich |

Hi Chris,
Quoting Chris Muller <[hidden email]>: > Would would have thought one good thing (this paper) could happen > because of patents.. Yes, defensive publications have a few great properties: - They don't need the horrible slang used for writing patents - They don't need to impress academic reviewers - You don't really need to "prove" novelty or relevance Then, it is just about the ideas, and describing them. Defensive publications will encourage writing stuff that is objective, precise and concise. Much nicer to read that patents, and easier to read than journal papers. > On Wed, Dec 4, 2013 at 7:19 AM, David T. Lewis <[hidden email]> wrote: >> On Tue, Dec 03, 2013 at 11:23:29PM -0300, J.

Hi David,
This work you did fits that 32768x32768 space into whatever display the user had? The first serious graphics stuff I did was around 1992, to do exactly that. I did a library for TurboC on MS-DOS that essentially implemented the wonderful 'draw' command from MS Extended Basic, but on a bigger space. I believe the size was 23040x16800 to have a reasonable aspect ratio, and to scale to Hercules, CGA, EGA and VGA using only integer arithmetic, and without artifacts. Quoting "David T.

The address space was 32768 x 32768, where (0,0) was the upper left corner of the screen or printed page. This was mapped to pixel resolution of the display or dot matrix printer. I provided makefiles for Microsoft C and Borland Turbo C as well as Xenix and Microport PC-AT unix, so it worked on at least those platforms. Funny, my makefile for MSC has a warning not to compile with the optimizer, which apparently did not work.
