Re: WashingtonDC dreamcast emulator

Its always good to have an alternative. You said it works on Windows via cygwin , I should try it on my AMD apu to see what kind of performance it gets on Windows. Heh you would put a polygon/triangle counter for research/fanboyism lol.

Re: Shadows/Lights example?

Presumably they simply render the player model once per light to a texture then render an additional pass of the scene with that texture bound. If it is only rendered once woudnt it be static? In the game it seems to interact with the light source and moves to match the player. Not to mention it se...

Re: Shadows/Lights example?

Seems Matt hoffman bmx did indeed use shadow mapping for the bikers shadow. I managed to extract that texture from the emulator. Seems to be a strange resolution of 512x256. Like I said Iam not a programmer but none the less tried to find an explanation and it seems because consoles have fast access...

Re: I present you a new multiplatform 3D library: LMP3D

This is pretty cool. You should consider posting it on Dreamcast talk. Maybe sending info about it to Dreamcast junkyard to get the word out.

Re: Might Scrap Makaqu. Possible to Finish Bero's Work?

Try one of those http://quakedev.dcemulation.org/downloads/codename/ Thanks. Got around to try and I must say it was very fun. It was a pain getting it to run but it was a nice surprise when it did. With some tweaking it could have been a commercial game. Its more fun than outtrigger in my opinion....

Thanks for the tip! EDIT: I found the code! Apparently it was released under the Return to Castle Wolfenstien Dreamcast sourceforge! You are welcome. I wish you all the best with your project. It'll be a hell lot of work for sure if you want to do both Q1 based game design/qc coding AND engine codi...

Re: Shadows/Lights example?

Are you working with the PVR API? shadow mapping can't be used effectively on the PVR graphics chip, because it doesn't have shader support. What you need to do in shadow mapping is render from a light's viewpoint to a depth texture (which the DC already can't do), then use this texture from your c...

Re: Working with Lighting and Shadows on the DC

The shadows in Matt hoffman BMX and Phantasy Star Online are so pixelated they're probably using shadow maps, aren't they? That seems to be the case for only 3 games on dc : Derby Tsuku 2, Matt Hoffman pro BMX and Urban Chaos.Phantasy star on dc no, but I think later versions for pc and gamecube di...

[quote="PH3NOM"]Thank you 8-) Here is a clip of the current build, using the shadow algorithm in the last screen I posted with 2 players. Shadows still need a bit of tweaking, but not bad for a first pass. Wow thats looking pretty cool. Hopefully you consider some sort of demo or maybe even creating...

Not a programmer but been following this since it can kick off 3d dreamcast homebrew in the future.Thank you for your hard work and hope this is included with kos by default. Seems like you might single handedly revitalize 3d dc homebrew.

I remember deunan (dreamcast emu author) addressed this.It seems the dreamcast is quite capable under the right considtions. Someone asked if it's possible to push 3M triangles through Dreamcast-based system in real-time. See the pictures below? The first two values shown in the second line are vert...

Re: Cubic Vr

The latest build has those bugs I experienced worked out, and the FPS is much higher on Dreamcast ( ~60fps at idle ) The render quality is very possibly the best I have ever seen on DC. It will be very interesting to see what we can do with this engine! At the very least, it is a very impressive te...
