Great issue thanks Colin Hi folks, Sorry for being so quiet recently, if only there were more hours in the day to get on with things! The very, (very!) late running SAM Revival 23 was released back in April. The coverdisk features Simon Owen's VIC-20 emulator and a few games, the full SAM Adventure 'Survive the Night' from Hydrasoft and Thomas Harte's latest 3D demo. (btw Thomas - fantastic work on releasing your 3D library! I'll be in touch shortly about that just to get a bit more info for the news in the next issue!). Inside there magazine itself there's the news section, and in the Developer Diary there's a look at the progress by Adrian Brown of porting a TCP/IP stack to the SAM, Thomas covers the work on his 3D engine so far and I go over the improvements I've made to the Trintiy version of B-DOS to give it a bit of a speed boost when reading from SD cards. There's also source code for the patched SAM ROM to auto boot from the Trinity. This issue of SAM Revival costs £3.99 including UK postage, or £4.79 including EU postage. If you've never tried SAM Revival before and would like to I'll knock a bit off for this issue - £2.99 (UK) or £3.79 (EU) - drop me an email directly to order or see my website. I'm now busy beavering away putting issue 24 together, and I'm aiming for this issue to be released at the end of June/early July. So far lined up for the coverdisk is 'The Witching Hour' by John Vincent, originally released in 1993. John as also painted a stonking cover for this issue! Inside issue 24 the Developer Diary looks at Simon Owen's work on his newest emulator, Rob Evans shows the behind the scenes work on his first SAM game Wubtris and his plans for more SAM games. Following my editorial last issue I've had a lot of feedback from readers (thank you!) so issue 24 is bursting to the seams with both letters and input to the new 'Comment' section I originally created in issue 23 as a back page filler! Also in this issue is a look at what happened to Sandman's Shadow - the point-and-click style game that was being developed by Gordon Wallis (it was briefly mentioned in the SAM Centre section in the last ever issue of YS). Gordon's gone out of his way to pass over the graphics and has taken photos of his developmental sketches to make this a really indepth look at what was shaping up to have been a SAM masterpiece.

Re: The 3d demo I supplied for Sam Revival 22
do you know what screen mode it is? only 14kb is it possible to reassemble to 8kb chunks to fit it in the bit after the 24kb of mode 3/4 screens? if it was mode 4(doesnt look like mode 3) can it be antialiased? is there enough t states left for interlacing or is that a lot more complicated? it certainly puts the dma version to shame! guess its not doing much other than drawing whereas elite was having to run a lot more code besides - is there room for the original in ram so that other ships could be viewed with your routines? or does your code have to have the data in a different way? rogerjowett1536 skype i might be able finally after ten years of trying to get the desktop to appear as the webcam rogerjow...@hotmail.com msn live! rogerjow...@yahoo.co.uk yahoo if anyone wants to try dont think gmail chat camera works at all rogerjow...@gmail.com if n e 1 wants 2 try On 20 April 2010 17:47, Thomas Harte tomh.retros...@gmail.com wrote: The only question I can answer: that demo doesn't support mouse input, primarily just because I've never looked into it.

Re: The 3d demo I supplied for Sam Revival 22
Hi Thomas, I've finally managed to test the Sam Revival 23 cover disk version, and it's very exciting! Great work! I'm really looking forward to having a go at making something with this, or at least trying to.. ;) Rob.
Re: The 3d demo I supplied for Sam Revival 22
I really should find the time to finish off the documentation and get it out there. I still have the vague notion of attaching or creating a high level language for the game logic parts that aren't so time critical, but don't intend to treat the issue as a sticking point. I really, really need to finish off the documentation. For Roger, and generally: it's Mode 4 but a traditional Bresenham rasteriser makes anti-aliasing difficult to achieve without switching to a slower algorithm. Models are described as vertices (seven bytes each), faces (ten bytes each) and edges (thirteen bytes each). Then there's twelve bytes to complete the model by tying the faces, edges and vertices together and for each instance of the model another eighteen bytes of positioning and rotation stuff. It's all still Eulers at the minute, though it all turns into matrices lower down so that wouldn't be too hard to replace. There was a late-stage 'optimisation' to do with objects that are mirrored across the x axis, which saves space and processing time for those. In retrospect I'm not sure it was that good an idea as the time saving may not be justified by the complexity. Per the Sam's paging scheme things are all a bit complicated, but per the standard design, models go on the same page as the internal lib3d code. From memory, that makes 15 or 20kb space for models. The Cobra Mk3 occupies 698 bytes, the cube 246 bytes, the Adder 524 bytes.
