看到討論提到SS版的莎木
就回一篇文
大家另外來討論好了
https://www.youtube.com/watch?v=iIWS7b84CAU
當年看到這段開發影片
真的很驚訝啊啊啊~
從這段展示影片觀察
"似乎"能夠看到
畫面有Perspective Correction和Bi-Linear Filter
這兩個3D表現的效果
Perspective Correction是透視校正
在SS和PS這二台主機上主機上,因為沒有這個3D功能
(家用主機初次具有這機能的是N64)
常見3D賽車或是3D動作遊戲在接近牆壁時,物件會產生扭曲變形
不過從SS版莎木影片中觀察,這種現象似乎不明顯?
Bi-Linear Filter是二次元平滑化
也就是3D物件在距離接近時,貼圖顆粒會變的粗糙,變成像馬賽克般
Bi-Linear Filter功能能夠讓粗糙感減輕、模糊化
而N64一樣也是第一台具有這功能的家用主機
在1994年發售的SS和PS都沒有這項硬體機能
但從SS版莎木開發畫面中
貼圖在近距離粗糙的情形好像也減輕許多?
另外,這段畫面中每秒呈現的多邊形數量
也好像超過SS主機應有的水準?
所以當時的SS版莎木畫面是如何達成的?
是將SS主機的二顆SH2 CPU完全發揮效能
去榨出這樣的畫面表現(也犧牲每秒畫面幀數)
還是SEGA其實有規劃SS的外置加速裝置?
例如像MD主機上SVP(Sega Virtua Processor)晶片
置於MD版的VR賽車遊戲卡匣中
能夠讓主機畫面呈現出超過本來的硬體機能
: → RuinAngel:我的意思是SS的卡槽就是拿來插Rom的所以就算做了晶片也 11/05 20:26
: → RuinAngel:沒辦法用那個卡槽,當然也不可能做在VCD上,所以SS要增 11/05 20:27
: → RuinAngel:強的話只能做個外接...? 11/05 20:27
: → RuinAngel:是說當年SS還有些遊戲是可以串兩台SS玩的,好像也是沒幾 11/05 20:27
: → RuinAngel:款,兩台SS兩台電視實在門檻不低XD 11/05 20:28
SS主機的擴充卡槽雖然實際用途只有做ROM卡匣、RAM擴充卡、記憶卡等
但我認為那個匯流排如果搭配加速晶片來做輔助運算應該也可以?
因為在用到ROM卡匣、RAM擴充卡這些遊戲表現上
可以推測這匯流排應有和主機CPU、記憶體溝通的通道
過往SEGA在設計主機/大型硬體上,很喜歡做多晶片
會保留SS主機的擴充能力應該也是有可能
而從當年MD的VR賽車中,它只是利用ROM卡匣插槽
在卡匣上裝載SVP晶片(聽說每秒9000個多邊形能力?)
也讓MD主機能呈現稍微可看的3D畫面
http://youtu.be/fakahDr_P2c
(不過MD版沒有方塊泳裝美女啊...只有32X版有,SS版也沒有)
還有當年的MD + MD-CD + 32X = 32X CD主機
也推出了6款專屬32X CD的遊戲
(其中Surgical Strike只有巴西版本)
雖然這幾款遊戲都是類似影片遊戲
但在遊戲運作時都是要用到32X的晶片,單MD-CD主機無法玩
從這也能看到SEGA在主機日後升級上應該都會有一些規劃
(SS主機上的擴充卡槽或MPEG卡槽)
當然,最後沒有出現這樣的加速裝置
實際情形如何我們也不得而知了
當年有買雜誌的話
我記得SS主機發行表上一直有VF3存在(VR快打3)
SS在移植VF1和VF2時,其實已經是越級打怪了
而之後的毒蛇快打和VR格鬥會使用新的演算法(雜誌提到)
應該也是SS主機上3D格鬥遊戲的極致了吧
那如果要出VF3,難道只是維持VR格鬥會水準
就冠上SS版的VF3嗎?
所以我才會猜測,SEGA是否會做像MD版VR賽車的方式
以CD-ROM配上專屬加速卡匣,來移植VF3
SS莎木也是以同樣方式推出
不過這樣遊戲的售價會變得很貴
當然...上面都是猜測而已
: 推 segafankwl:SS莎木的fps只有15左右,比多數SS遊戲低,藉此換取畫面 11/05 20:41
: → segafankwl:表現的提升,當然製作技術的程度也是畫面表現差異的原 11/05 20:42
: → segafankwl:因。另外SS是以四邊形為畫面構成基礎,而非3角形,所以 11/05 20:43
: → segafankwl:即使沒有透視校正,透視錯誤的情況也比較不那麼明顯 11/05 20:43
segafankwl大說的也是有道理
的確有可能將主機的運作資源分配(犧牲fps數)
來進一步提昇畫面表現
還有開發新的演算程式,榨出二顆CPU的效能
不過...
SS莎木永遠沒有發售
事實如何也不得而知了
SS主機在1995年~1996年時
我記得銷售量還稍微超過PS主機
讓人覺得大有可為
可惜後來還是後繼無力
就如板大在前篇說的,SEGA的失敗讓很多玩家感嘆
SEGA退出家用主機市場,可以說是一個時代的結束啊
