Aw: JavaFX Direct3D 12 rendering pipeline for Windows

[Marius Hanl]

In my opinion this is a nice change.

Modernizing the Windows backend of JavaFX is a good idea and will also enable us to use more modern features if needed.

There should be some performance improvements as well.

Even though Direct3d9 works and is not deprecated, I still think it is good to move on with the technology.

I guess that at one point (when everything is more stable and tested), the direct3d12 backend will be enabled as the default?

When I have some time, I will check it out as I'm curious myself about this.

Betreff: JavaFX Direct3D 12 rendering pipeline for Windows

Hello openjfx-dev,

 

we just pushed a prototype of a new JavaFX Direct3D 12 rendering pipeline

for Windows to a new "direct3d12" branch on jfx-sandbox. It is more than an

experiment branch - we intend to fully develop the D3D12 backend there.

 

We're not necessarily looking for contributions at this point, but if anyone

has early feedback about it or wants to try it by building it themselves,

that would be fine. We also did not test it on a wider range of hardware, so

your mileage may vary. While D3D12 pipeline will build by default, D3D9

pipeline is still the default pick at runtime. To run anything on D3D12

pipeline you need to force it with ex.:

  java -Dprism.order=d3d12 ...

 

Backend supports 2D rendering (albeit with some graphical issues here and there

that need to be ironed out) and basic 3D rendering. Expect not everything fully

working yet (ex. some gradients on 2D controls are incorrect, or 3D-in-2D will

straight up not work) and the performance not matching D3D9 yet. Our goal is to

first reach feature completion and then focus on performance.
