Holly 3D engine for Dreamcast

Post by Segata Sanshiro » Fri Jul 29, 2005 8:28 am

If this is old news and has been discussed before, please feel free to delete or lock this topic!!

ABOUT:
Holly is a 3D engine SDK for the Dreamcast and is build on top of KOS 1.3.x (KallistiOS). It is implemented in C++, with some amount of SH4 assembly. The main developer of Holly3D is Heinrich Tillack. You can get in contact with him via E-mail info(at)tillack.org.

History - from Iris3d to Holly: In 2002 I added Triangle Strips clipping and IMD animation with vertex interpolation to Iris3D V0.7 by Olivier Chatry. Olivier the author of Iris3D included the patches into Iris3D V0.9.1. Which is the last official version of Iris 3D. In 2003 I started to modifiy this C++ code just for fun! Since 2003 I replaced (rewrote) around 95% of the C++ code, so I called the SDK Holly and NOT Iris-3D V2 as I thought before. Too much has changed - compared to Iris3D. I rewrote Iris3D just for my own game projects (like DCASTLE). So here it is. Stay tuned for the upcoming release....
Implemented Features:
Performance:

- Aggressive Culling
- Triangle Strips (via IMD3 file format)
- Triangles for smarter quadtrees(via IMD3)
- memory friendly resource manager, just load resources when it`s not already loaded

Game features:

- Collision Detection with OPCODE 1.2
- Billboards
- 3d meshes(IMD3 format)
- Easy Controller tests
- support for large static levels with Octree scene managment

Visual effects:

- Rendering Opaque and Translucent objects
- Lighting - dynamic RGB lights, point , directional (Sun).
- Special Effects - range-based fogging, depth-based fogging,stencil shadows
- Textures - multi textures, compressed textures,

Import / export

Implemented Renderer

Dreamcast / SH4 optimized software T&L

Cool, sounds like he's porting Iris3D. I, on the other hand, have always wanted to try to port Irrlicht3D. It'll be cool if this guy makes a release soon.

Some guy over at CubicVR 3D engine forums said he worked on a PC game using this engine, and it turned out pretty good looking. Would be nice if it were ported over to Dreamcast.

http://www.cubicvr.org/index.php?option ... itstart=24

This is what he worked on, maybe somebody should contact him to see what happened to the Dreamcast port they were planning?

Might be worth looking into for potential developers.

hey guys,
i'm the same
guy over at CubicVR 3D engine forums he worked on a PC game using this engine
... the story is like this:
I worked with Heinrich doing the graphics (models/textures) for a 3D platformer demo/game that would come out with the release of Holly3D while he was developing the engine itself. As time progressed, Heinrich built the demo and i had it running on PC, it was not a PC game made with Holly3D. As far as i remember, back then, Heinrich got some real life related issues and could not afford the time to work on the project anymore.

PS: what you see in the PC shots is very close to what it should have looked on the DC. The whole level was around 3k polys + 50 textures and they fitted nicely into the 4Mb budget we had.

Hey Nuke. Feel like working with a few peeps on a DC game (graphics and textures department)? We could always use more help. :wink:

Ah now that I think about it it was you lol.

So it was just abandoned or what? Could it ever be looked at again and see if it could be ported as a tech demo or something? Does a PC demo exist that you could share?

What happened to Heinrich?

Sorry for all the questions.

Hey DanteJay,
always happy to help my fellow Dreamcast brethren. What's your project? Do not get offended, I've been out of the loop for the last 5 years. You can contact me on info _at _clandestinestudio _com

Anthony817, Hainrich had personal issues which i didn't want to invade, so i don't know what happened with him. I wish as much as you do for a release of some sort... on the other hand our work on dcShooter with the French team was very advanced, i think even more so than Holly. You can find more info and links on another post i did in the CubicVR forum topic.

Interesting thing - for the first time by the name 'HOLLY' where hided the dev board with CLX1 and CLX2 chip on it (PowerVR2, exactly), and it was official dev board which used in developing games thru Kamui (application driver layer) shipped with Katana. Lol.
About the engine. Are sources exist? Can I dwonload it or use in some ways for my own game development etc?
How do I try to build a Dreamcast toolchain:
