Zoals in dit nieuwsbericht al gesuggereerd werd zijn de geruchten rond het mogelijk aanwezig zijn van hardware-versnelde Transform & Lighting hevig de kop op gestoken:
Here's what Khong Jye Liew author of MGA Tweak had to say.All right, guys. Rather than debating on such matter, why don't we refer to the chip specification. This is what it says: "...These are the 64 multi-purpose WARP registers (WR0, WR1,...., WR63). They can represent an IEEE single precision floating point number, a fixed point 32-bit integer, two 16-bit words or four bytes. It is up to the software to define what to put in these registers and how the microcode will interpret them..."
At first, I was rather confused when I first saw this. The WARP engine is meant for triangle setup which is integer intensive, but Matrox actually built it with floating point capabilities. And, the WARP is FULLY PROGRAMMABLE.
I am no 3D programmer, I don't know whether single precision IEEE FP will be sufficient for T&L. I have long been suspecting the capability of G200/G400 to do T&L if the WARP can be programmed to do so. Well, it still depends on whether the whole WARP architecture is optimized for T&L processing. If Matrox only do T&L in the so-called new "G450", then probably they are optimizing the WARP for T&L processing.
The really interesting upshot of all this speculation at least is that is adds weight to the rumour that the new G450 chip will come with some form of T&L. It brought a smile to my face that after posting a rather tongue in cheek comment in the forums about "knowing the G450 would support T&L" I was very quickly contacted by Matrox wanting to know where I had obtained the information, what more proof do we need that it is fact
