Hi all,
It's me yet again lol, (edit: don't know if anyone saw the first post of this engine on the propgfx forum.)
Just an update I've now coded the vertex rotation and poly zsort and back face culling in asm, and gained a significant speed increase, next stage is to then spread that across multiple cogs for even more speed [noparse];)[/noparse]
You'll also notice, by this image posted, that the black borders in the middle, is the time it takes the PropGFX Lite to clear the screen and draw all the polys [noparse]:)[/noparse] how good is that, showing there's plenty more grunt in there for another 2 ( 400 poly ) men easy PS, that's NTSC 60fps, you just need to get the data fast enough now, which should be sorted when I've got the processing done in multiple cogs.

    For those who haven't already seen this post, this is a proof of concept virtua fighter demo for the Hybrid/Hydra + PropGFX Lite platform, it's not a game as such more to show of the capabilities of the Lite's poly engine.

    We are finishing off the new website and e-commerce shop then we will be launching 1st November.

    Regards,

    Coley

    tpw_man, the PropGFX Lite plugs onto our Hybrid expansion card, which is Hydra compatible, so yes, it will already work on the Hydra too [noparse]:)[/noparse]

    Can you texture the polygons? If so, seriously do a Super Propeller 32!(Super Mario 64)

    Thomas,

    PtopGFX Lite comes with a riser card like the ones in the attached photo specifically for Hybrid and Hydra platforms

    smile.gif

    attachment.php?attachmentid=56164

    It also doubles up as an experimenter card and will be available seperately through our site.

    Regards,

    Coley

    Holy Smile that is awesome! I can wait to see another character and some controllers hooked up to it.

    So now I need some details:

    1) Where is the image being rendered at (which Prop, and if both what is getting done on which one)?

    2) how much free ram is left on the two props?

    3) Is this going to be open sourced or more closed api?

    4) How do you create the 3d models (entering each triangle, some sort of cad program..?)

    Hi JT,

    Yeah it is awesome, yet another example of how talented Baggers is at squeezing the best out of this amazing micro...
    JT Cook said...

    1) Where is the image being rendered at (which Prop, and if both what is getting done on which one)?
    The Polys are rendered by PropGFX Lite but the tri information is back face culled, sorted and sent by the Hybrid

    2) how much free ram is left on the two props?
    PropGFX Lite - Not Much, the display is 128*96 double buffered, Hybrid - Enough to squeeze in another character and some control logic.....(2800 Longs)

    3) Is this going to be open sourced or more closed api?
    Closed API, we've put far too much work into it but it will be reasonably priced and we will have licensing arrangements

    4) How do you create the 3d models (entering each triangle, some sort of cad program..?)
    Somehow, Baggers just happened to have them tongue.gif

    Thanks JT [noparse];)[/noparse] yeah, I'll most likely do a little simple fighter demo with it. even though it's only really a tech demo, showing the poly pushing power of the PropGFX [noparse]:)[/noparse]

    so some more detailed details for you... [noparse]:)[/noparse]

    1. the image is being renderd on PropGFX, by clearing the screen then drawing a poly list ( which is created on the Hybrid / or protoboard ) ( ps the black border in the top picture in the middle of the screen is the time it takes to clear the screen and draw the poly list. ) the hybrid is ( at the moment in one cog ) preparing that list, by rotating the verts, and zsorting and back face culling the poly's. [noparse];)[/noparse]

    2. on the Lite, I have 12K for each screen display as it's double buffered 128x96x8bit colours for full colour range, and bottom 1K is Lite data + line render, 256 bytes for palette rest can be for poly list.
    On Hybrid, I have about 12K free [noparse];)[/noparse] will use 8K of that for SD so I can load each frame of vertex for each player each

    3. Contrary to what Coley put, the Hybrid source ( the vertex rotation and zsort and backface culling etc ) will be given on the examples disc with a PropGFX purchase, so you will be able to make your own 3D games / demos etc [noparse];)[/noparse] ( PropGFX is closed API though )

    4. The models I already had from a 3D tech demo I did for GBA, were done on a professional 3D art package, and converted with a converter I wrote, but the package isn't a free one, but the data required is very simple, and can be changed from other free programs, if people have a program package they use, then if the output is an ascii format, I may convinced to be able to knock up a quick conversion app for you. I might even do a MD2 model format to my format converter, if I get enough requests [noparse]:)[/noparse]

    Living on the planet Earth might be expensive but it includes a free trip around the sun every year...

    Experience level:
    [noparse][[/noparse] ] Let's connect the motor to pin 1, it's a 6V motor so it should be fine.
    [noparse][[/noparse] ] OK, I got my resistors hooked up with the LEDs.
    [noparse][[/noparse]X] I got the Motor hooked up with the H-bridge and the 555 is supplying the PWM.
    [noparse][[/noparse] ] Now, if I can only program the BOE-BOT to interface with he Flux Capacitor.
    [noparse][[/noparse] ] I dream in SX28 assembler...

    Looks pretty good! You should look into Blender since it is freeware and might be a good 3D modeling tool to support.

    Last of the demos, as it's going into production, yes, a little late, but I'm sure you'll like the results [noparse]:)[/noparse]

    This one shows some C64 4 colour bitmap mode patterned poly's then loads a C64 game loading screen + attrs, then adds some C64 style sprites, then goes to the speccy style mode for some 2colour patterned polys + 16 colour sprites on top.

    Rofl Jeff, I'm trying not to do anything more other than make sure the PropGFX gets out now soon as we've got em made up.
    Then I'll start on some games for it.
    first will probably be a simple playable version of the VF demo I did. [noparse]:)[/noparse]

    I must be blind or something, because I can not find anyplace where you can actually buy these. I've seen plenty of screen shots and videos. (I'm using both Google and Bing to search.) The site PropGFX.co.uk has a forum, but it hasn't been updated in a while. Their "store" doesn't have anything listed either.

    I've seen some nice pics of one (on this thread) but that is the only place.

    Am I going crazy?
