DxNext

[Nemesis11]

Estava a ler um outro forum e encontrei uma thread e um ppt que fala sobre os objectivos da proxima versão do DirectX.
Achei interessante criar uma thread sobre isto.

-Goals
-Customers
-I/O Model
-Shader Programming Model
-Surface Models
-Topology Operations
-Frame-Buffer access in pixel shader
-Virtual Video Memory

Goals
-Enable scenarios currently blocked
+Many desirable functions must still be performed on the CPU
-Add generality to reduce number of future scenarios that may get blocked
-Optimize interface to future OSs
+Better primitive throughput performance
+Better state change performance
+Better interoperation of multiple apps/processes

DirectX Graphics Trends
-DirectX Next: dynamic geometry/topology modification
+Move CPU/GPU transition to point of very low bandwidth
+Enable new capabilities for new GPU uses

General Programming Model
-Integer instruction set
-Support for more programming constructs
+stacks and arrays
-More flexible memory addressing
+less texture specific
-Resources are unlimited
+temporary memory store
+instruction count
+iterators, streams, etc.
-Non-real-time usage can be slow
+Performance may drop drastically below 640x480 10 Hz
-Improves hardware as an HLSL target
+All algorithms will at least compile instead of hitting instruction count limits
-Identical for all shader model 4.0 shaders

Acho que tem informação muito interessante, como memoria virtual nas gráficas, Shaders 4.0, uso do Dx no interface do OS, etc.

P.S. - Não sei se este é o melhor sitio para criar esta thread. Está ligado às graficas, mas......
Se quizerem mudem.

Back from the dead........

Um optimo artigo sobre o Dxnext ( http://www.beyond3d.com/articles/directxnext/ )

In fact, many of the major DirectX Next changes seem to be a perfect fit for tile-based deferred renderers.

Será que vamos ter alguma coisa nos proximos tempos..........
