Anounced today the Game Developers Conference, OpenXR is an open standard for portable Virtual Reality (VR) and Augmented Reality (AR) applications and devices.

The cross-platform VR standard eliminates industry fragmentation by enabling applications to be written once to run on any VR system, and to access VR devices integrated into those VR systems to be used by applications.

or does geeXLab need windows and cannot display directly onto the framebuffer?

GeeXLab for RPi exists in two versions: one with OpenGL 2.1 and one with OpenGL ES 2.0. GeeXLab with OpenGL 2.1 requires X11. GeeXLab for OpenGL ES 2.0 does not use a window manager, it renders the scene  directly in the framebuffer. Maybe you can try this version, and start GeeXLab and load scenes via command line.

In the code sample pack, you will find OpenGL ES 2.0 demos in the gles-20/ folder.

Palit Microsystems Ltd, the leading graphics card manufacturer, releases a new line called KalmX and is consist of GeForce GTX 1050Ti series. With passive cooler and the advanced powerful Pascal architecture, Palit GeForce GTX 1050Ti KalmX - pursue the silent 0dB gaming environment.

Palit GeForce GTX 1050 Ti KalmX Features:

- The first passive cooler for GTX1050 Ti in the market
- Two nickel plated heat pipes
- Vast volume of nickel plated fins
- Copper base with heat pipes for best heat dissipation from GPU to fins
- No external power required, good for small case PC
- Affordable GTX series product, great C/P value
- Great Hardware Components

- GTX 1050 Ti KalmX press release

Ok, I think recent drivers from NVIDIA and AMD come with serious changes in Vulkan API that can explain the crashes. I prefer that. I have to dive in my Vulkan code (GeeXLab) and hunt the bug! I will do this asap.

Parallel BSP traversal in compute shader, outputs sorted IB, transparent scene rendered in 1 drawcall.

- Demo description
- DX11 demo (source + exe)

Back in the early days of consumer level 3D graphics hardware, BSP trees were a common component in rendering systems. Over time it fell out of fashion as the geometric complexity increased exponentially, scenes became more dynamic, and mesh data and processing moved over to the GPU side. With that said, BSP trees do have a number of desirable properties that made them attractive solutions for the static world geometry. One such property is that one can easily traverse a BSP tree in strict visibility order. If you don't have a depth buffer, you can render things correctly by traversing it back-to-front, and if you do have one, especially with Hi-Z rejection, you can instead traverse it front-to-back and get the maximum utilization of that hardware. Now this may not be a major concern today, but sorting things for transparency is still a problem we struggle to solve properly, and for static geometry a BSP tree can solve that quite elegantly.

look - my comment about your ASUS GTX 1080 TURBO review. ;)

NOTE: sorry for wrong thread but I tried to send you this message in PM but this doesn't work. ::)

No problem. Yes I saw your message about the GTX1080 and the bad R376.09 driver...

Can it run without the windows manager? (no XWindows, directly from terminal)
I don't understand what do you mean. Do you mean you can start GeeXLab from the command line (with options)?

Can the whole screen resolution show nothing but the visual programmed? i looked at the demos and they all had descriptions on screen

Yes absolutely. All descriptions you can see on demos are just for information. You can control their rendering by code. Actually, you have to code the display of information, because GeeXLab does not do it for you. GeeXLab renders exactly what you have coded. It does not render things that you didn't code. Some demos use frameworks (like the kx framework) to make demos coding easier. But you are not forced to use them. You can code with the low level GeeXLab API (lua and python) or create your own framework/lib. You are free!

thanks for the report. I will test the Vulkan demos with a RX 470 asap!

Will it see the day of light?
