What happened to the Direct2D Renderer?


#1

I want to speed up drawing on Windows, the OpenGL-Context in Plugins seems to be to unstable (escpacially on windows, driver issues etc.)

I looks like the Direct2-Context was never finished?

 


#2

Actually, I had completely forgotten about its existence until recently, but a couple of weeks ago I fired it up and was surprised to find that it seems to work perfectly. Whether or not it's faster is something I'd be interested to hear about if you try it.


#3

When i define JUCE_DIRECT2D i got a lot of different errors while compiling the JUCE demo, did i miss something?

So windows uses still use the software renderer per default, so no GPU involved for graphics processing?

#4

Hmm, ok, maybe I was mistaken about that. Will look again when I get chance.

But yes, by default we're still using the software renderer.


#5

+1 for enabling Direct2D rendering!


#6

I'd love to see a proper Direct2D renderer. As it's been said, the GL renderer isn't without its issues, especially when it comes to the message thread locking when mixing JUCE drawing with GL drawing which honestly makes it unusable for general 2D GUI drawing as far as I'm aware because of all the wasted cycles. It's weird because it get significantly higher framerates but way more CPU usage.

The performance of the CoreGraphics rendering under OSX is awesome, but the speed of the software rendering under Windows once components start needing continous repainting is terrible.


#7

In the thread linked below, @jules has stated that they are thinking about the features of JUCE v5.

What about adding the completion of the Direct2D renderer to the list?!?

The fact that a library so mature and good at cross platform and GUI still does not support it looks so silly to me… the more because it has been repeatedly mentioned in the forum that there is already something half finished for that.


#8

I’m wondering if it may be skipped over in favor of Vulkan/Metal support:

In addition to having a LowLevelRender implementation for JUCE components I’m dying for a barebones Vulkan context component in JUCE to render in, and the supposed increases in performance from these new APIs sounds promising. Of course, this is back in August 2015 and we haven’t heard anything since, so who knows where it’s gone…

Unfortunately it doesn’t seem like JUCE’s software rendering performance has scaled extremely well with HiDPI displays (which is unavoidable) - let’s hope some hardware acceleration can fix that.


#9

An news about this, now that JUCE 5 has been released?

The software renderer on Windows is still quite slow in comparison with stuff on macOS


#10

What’s the status on this? There was a fat commit back in June that looked promising, but as far as I can tell the Direct2D renderer still isn’t enabled by default on supported platforms…


#11

It’s still on our todo list, but we’re not working on it at the moment. As it currently stands it’s an incomplete implementation.
