Power VR Series 5 - Where are the rumours?

[Lonyo]

On the Power VR website they have released some PS3.0 demo's, which suggests they have some PS3.0 hardware (series 5) which might be competition for the R420/NV40.

Anyone got any rumours about anything new from Power VR?

Cloth animation (PS3.0 and VS3.0)
Voxel rendering (PS3.0)
Deferred shader rendering

Beats me. Download the source and go hunting to see if you find anything. 😉

What is pixel shading? And why do we need AnsioScoptric Filtering? How come the textures blur out in a 3D enviorment anyway?

search for the word series5 and you will have enough rumors and speculation to make your brain explode

The Series V card will use TBR, as usual--they will never make an IMR card.

Clock/mem speed will probably be around 300Mhz+.

It will be a DX9.1 card with vertex/pixel shader 3.0

What is pixel shading?

Programs that execute on the GPU and manipulate the state of pixels and texels.

And why do we need AnsioScoptric Filtering?

"Anisotropic"

It's needed to sharpen textures that are mapped to an angled surface.

How come the textures blur out in a 3D enviorment anyway?

Because square filtering methods like bilinear and trilinear can't deal with non-square situations such as those where textures are mapped to an angled polygon.

TBR is pretty nifty, the old Kyro2 cards were more than a match for the cards they priced against. I wish they'd had better drivers though, and more support.

Pixel shading is one of the key features in DirectX9. It allows complex, realistic looking graphical effects to be calculated in the GPU much faster than ever before - ie (a generic example): an effect that would take, say 6-10 passes on the GF4 could take 1 on the Radeon 9700 and up, etc. Complex effects that might take 50 passes with Pixel Shader 2.0 may take only 5 passes. In layman's terms it allows very pretty graphical effects to be rendered at playable framerates.
