Manufacturer: Sega | |||||

The Sega Hikaru is a successor of the Sega NAOMI and Sega Model 3 arcade systems that was developed in 1998 and debuted in 1999. The Hikaru was used for a handful of deluxe dedicated-cabinet games, beginning with 1999's Brave Fire Fighters, in which the flame and water effects were largely a showpiece for the hardware.
It was significantly more powerful and expensive than the NAOMI. The Hikaru featured a custom Sega GPU with advanced graphical capabilities, additional CPU and sound processors, various custom processors, increased memory, and faster bandwidth. It was the first game platform capable of effective hardware Phong shading, the most intensive form of shading at the time, and was capable of the most complex lighting and particle effects of its time.
It was the most powerful game system of its time (Planet Harriers in particular was regarded as having the best video game graphics at the time), but it was very expensive. Since it was comparatively expensive to produce, Sega soon abandoned the Hikaru in favor of continued NAOMI development. It was succeeded by the NAOMI 2, which was not as powerful, but more affordable.

Development
According to Sega in 1999:[1]
“ | Brave Firefighters utilizes a slightly modified Naomi Hardware system called Hikaru. Hikaru incorporates a custom Sega graphics chip and possesses larger memory capacity then standard Naomi systems. "These modifications were necessary because in Brave Firefighters, our engineers were faced with the daunting challenge of creating 3d images of flames and sprayed water," stated Sega's Vice President of Sales and Marketing, Barbara Joyiens. "If you stop and think about it, both have an almost infinite number of shapes, sizes, colors, levels of opaqueness, shadings and shadows. And, when you combine the two by simulating the spraying of water on a flame, you create an entirely different set of challenges for our game designers and engineers to overcome; challenges that would be extremely difficult, if not impossible to overcome utilizing existing 3D computers. Hikaru has the horsepower to handle these demanding graphic challenges with clarity, depth and precision." | „ |
In addition, the Hikaru also uses two Hitachi SH-4 CPU processors, two Yamaha AICA sound engine processors, a Motorola 68000 network CPU, and a dual GPU setup. The Hikaru hardware was largely complete in 1998, before it was released to the public in 1999.[2] The word "Hikaru" (ひかる) means "to shine" in Japanese.

- Effects: Stencil, shadows, motion blur, particle effects, fire effects, water effects,[1] fog, alpha blending, anti‑aliasing, specular effects,[21]
- Features: Tiled rendering, deferred rendering, back‑face culling, hidden surface removal
- Phong shading: Per‑pixel lighting/shading computation processed by rasterization pipeline,[22] deferred rendering prevents shading of overdrawn pixels to maximize rendering bandwidth,[23] all compute units could be used as shader units to maximize Phong shading performance
- Texture capabilities: 16×16 to 512×512 texture sizes, mipmapping, mipmap trees, texture panning, multi‑texturing, bump mapping, normal mapping, texture filtering, bilinear filtering, trilinear filtering, environment mapping[21]
- Texture banks: 2 texture banks (stored as 2× 2048×1024 sheets), stores textures from MaskROM (with 16‑byte metadata per texture in Command RAM)
- Floating-point performance: 32.678 GFLOPS[n 1]
- Phong shading performance:
