I want to thank here bjbdragon's contribution without which I would not even be aware of sse2neon's existence... I also want to thank Tanuki for his contribution to pre-built libraries support.

Today, I made Linux aarch64 (ARM v8 only) builds officially supported, with updated pre-built libraries source scripts allowing to rebuild those libraries on (hopefully) any x86_64 and aarch64 Linux systems.

The Cool VL Viewer sources are now officially compatible with aarch64 Linux systems. :P

I will soon open a FAQ topic about how to use the Cool VL Viewer on ARM64 SBCs (I am myself still learning about one of them, the Orange Pi 5 Plus). EDIT: see the new Linux ARM64 install howto.

Sorry for Ghosting a while, rl troubles, anyway, i noticed the sse2neon prebuild isnt updated since a few releases, requiring to manually add and change the install.xml for it to build. Since your hosting a newer version than in the install.xml set.
I also like to thank you for making these builds now. The dependencys where rather finicky to get working right when i did build them. Sorry it was such a mess.
(Also Good 30+ fps on RK3588, with panfork, where getting there, next SBC's even better, perhaps even vulkan or opengl good enough for PBR!)

In fact, it's the other way around: I forgot to upload the new version to the website (it's cached in /vart/tmp on my build system, so I did not notice it). Fixed now.

At what resolution ? I'm barely getting 10fps at 1920x1200...

Can't even get ALM to work with Mesa on my Orange Pi5+... :cry:

Fullscreen its 10-15, yeah but, not Fullscreen, at 1230x700 its around 20 FPS at a very densely build sim (rrdc) And my own place that has much less geometric stuff all over, i can see up to 20-30. That on a Radxa Rock 5b.
I can't currently run ALM too due the panfork mesa bugs out and no vulkan with it. (things ghost pink) or PBR atm, and the adapters to plug in a real GPU via nvme, are quiet expensive, and untested. If we had vulkan, opengl could work via zink... (need to test the RPi5 when i manage to get one, it was sold out for months..)
I'm hoping thus, that perhaps the next generation will offer better GPU connectivity, the RK3588 already outperforms a FX-8350, CPU wise..

The CPU is definitely not the bottleneck in ARM SBCs. The GPU is the problem (Mali sucks rocks... Thus Rockship ? :lol: ).

Now, it would be interesting to know how well the viewer would run on an NVIDIA Jetson-based SBC, which got a proper and powerful GPU... Sadly, these SBCs cost an "arm" (the member, not the CPU :lol: )...

I'm waiting for some Radxa Orion O6 to toy around with.

12 cores in total ARM v9 based, Cortex A720/A520, 32 GB RAM, 5 GB Network and a PCIe 4 16x slot.

Curious to see how fast the ARM G720 GPU will be.
But well, the board has a PCIe slot, so you can slot in normal cards, as long as you get driver support for ARM, which seems to be the case for AMD devices.

So will post some infos once i get it and get the viewer to run on it.

Nice ! 8-)

Oh, and NVIDIA also provides Linux ARM64 drivers...

You could slot some "old" graphics card in this board (e.g. a GTX960+), and then you'd certainly get some very usable system for SLing !
