IRIS 3-D Engine for Dreamcast has just been released, here is a list of current features & the to do list for future versions:

Features:

• Fast rendering using PVR API from KOS.
• Iris Model file format, using stripped triangle list as base primitive.
• Software clipping of triangle strips.
• Importer/Exporter, converting MD3 to a custom IMD format (Iris Model).
• Animated mesh (using sampled vertex morphing, taken from MD3).
• Material manager
• Object manager
• Geometry pipeline
• Lighting pipeline: dynamic lighting (Omni light, Francis’s “Smousse light”).
• Frustrum culling using bounding sphere around object.
• Collision detection using opcodecollision library.

Left to do:

• Entity manager, event/trigger based
• Precalculate lighting
• Documentation (using together maybe…)
• An actual GAME based on the engine 🙂
• Probably plenty of other things…
• Vertex tweening (lerp between animation)
• Some sample

You can download it from the IRIS 3-D Engine for Dreamcast homepage.
