Re: New to Dreamcast homebrew, question about engines

I've written a few games with C. I'm more experienced with C#, but I had no expectation of using that language on the Dreamcast. I haven't written any kind of networking for games outside of a few Unity prototypes. That was something I was planning to learn over the course of this project. unity ha...

Re: New to Dreamcast homebrew, question about engines

I'm bored because of corona-time, so I decided to comment. Please don't take it the wrong way, if something *might* sound rude - it's definitely *not* my intention! have you programmed games before? how familiar are you with C? have you ever implemented network functionality in games? I've been cons...

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

1) It has left me very crazy XD. Also with a lot of curiosity and I have researched a little. And yes, it's incredible but it's true! Already the PS1 in GTE has a function / macro for "Outter_product". That costs 6 cycles. It is true that the lighting operations "Inner_product" ...

most likely. i do know my znear-clipping code broke before when compiled with -O3, but looked fine with -O2

Re: Graphics corruption on real hardware

huh... i am cleaning up my rendering source code. removing unused functions, static variables and so on... and there is one big unused function - if i delete it or comment it - everything breaks on emulator too. it compiles and links without it, but graphics breaks. if i leave it in - it works on em...

Re: Graphics corruption on real hardware

thats the same experience i've made - lxdream is nearly unusable for commercial games, but it somehow works best for homebrewed stuff. I'm aware that the dreamcast emulators don't emulate the hardware properly and use many workarounds for performance. there is an elf file attached (game data is comp...

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

this is pretty cool! the z-near clipping and lighting is not implemented yet? or did i missed it? i only took a quick look so far, i really need to adjust to your coding style first. wouldn't it be better to write the assembly stuff in extra *.s or *.S files instead of inline asm? :D are you interes...

Graphics corruption on real hardware

Hi, I'm writing a little game for the DC and it is coming along nicely. the physics and input systems seems to be working fine, but I'm having problems on the graphics side. The whole thing is in 3d. I'm using the direct render interface in KOS, so no KGL. It does run and producing correct output in...

Re: A serious discussion: porting open source engines to DC

in short for all three of them - a hell of lot work. What would be involved in successfully porting one of those to Dreamcast? "Downscaling" the visuals of the engines until the engine performed at decent framerate? Or is it deeper like porting all of the libraries used in the engine? Or r...

Re: Terrain texturing

Hi B0b Just seen your post. For the terrain I'm using a greyscale 8-bit image which gives you 256 possible height values. This can be scaled up for more height, but will increase the visible step size unless you do some smoothing. A 16 bit heightmap can be used but that increases memory usage. yes,...

Re: Terrain texturing

Terrain is generally very easy; the height map r,g,b values are interpreted as x,y,z, and viola, 3D terrain. yeah, well, except it isn't if you are trying to render detailed terrain with good draw distance. you have to implement some sort of LOD-system. nowadays on newer hardware you can do pretty ...

Terrain texturing

Hi Everyone! I need some programming support... I'm implementing a terrain renderer. I'm using OpenGL on the PC side but I'm going PVR-only on the dreamcast. The terrain LOD system is mostly done... And now I'm trying to figure out how to properly texture this thing. I have like 4 different textures...

Re: Hucast is looking for a coder to build a KOS based Frame

I'm in touch with some DC coders now and they all say an port to DC will be easy if they have the Open GL based PC version of the game, so this it what we will now work on. thats that I somehow tried to say. OpenGL-based PC version alone doesn't guarantee an easy Dreamcast port. For example I would...

Re: Hucast is looking for a coder to build a KOS based Frame

I don't know what you mean by "framework", but... I haven't tried setting up the toolchain for windows as i use linux and osx most of the time. I think you should explain a little how your PC version is made so far. What libraries you use (opengl, openal, sdl etc), is it in c or c++ and so...

it's an interesting project. i couldn't care less for "Saber Rider" (never really watched it, but find the intro very catchy). i mean i've seen some episodes as a child, but never got into it. that said, i'm a big fan of on rail action games like starfox and sin & punishment series. I'...

Re: Fightoon video

I can understand your reasons. The fps problems is quake-specific (afaik in q2 & q3 too). animations with milkshape is a payne. milkshape is great for converting models from one game-format to an other. i would not use it for modelling and animating. can you still release the source code you hav...

WTF?! Great work Fragger! cel-shading in quake1? really nice! it is faked or real cel-shading? i mean, are the outlines made by the renderer or it is the old trick with the models (models have the outlines "built-in")? i know, the graphics and the whole game itself are in very early state....
