Small OpenGL survey for my LDCad 2.0 plans

[Roland Melkert]

Hi all, I'm at the (GUI only for now) rendering engine building stage of LDCad 2.0 and was wondering which minimal requirements to target.

OpenGL 3.3 has a couple of handy things over 3.2 (e.g. attribute layout etc), and 4.x has even cooler stuff but support for that version seems low unless I go into the extension soup.

So I was wondering which version of OpenGL do people currently using LDCad have available, you can see this by opening any log file

--- Edit by Willy ---

which usually can be found in: C:\Users\<Username>\AppData\Roaming\LDCad\logs

-----------------------

and do a search on "OpenGL" this should give you a line like:
00144 | 2017-10-03_20:06:49 | Info     | Initializing render manager | OpenGL platform information: vendor "ATI Technologies Inc." renderer "AMD Radeon HD 7900 Series" version "4.5.13431 Compatibility Profile Context 16.150.2211.0".

In this example the OpenGL version supported is 4.5


LDCad 1.x can use OpenGL as low as 1.1, but I'm not planning to go that low for LDCad 2, currently I'm thinking 3.3 or maybe 3.2 depending on the answers on this thread.

OpenGL 4.4

OpenGL 4.5.0

I can't open a log file, I can't even fire up my PC because it's in pieces waiting to be upgrade.
However, according to Nvidia the OpenGL version for my GPU is 4.5 if that's the same things as what you're looking for.

My laptop has 4.4 btw, but I generally don't use that for LDCad.

4.4 here

OpenGL platform information: vendor "NVIDIA Corporation" renderer "GeForce GT 730/PCIe/SSE2" version "4.4.0".

My laptop is 4.4 too

OpenGL platform information: vendor "Intel" renderer "Intel® HD Graphics 620" version "4.4.0 - Build 21.20.16.4526".

But my main machine is 3.3

OpenGL platform information: vendor "NVIDIA Corporation" renderer "GeForce GTS 240/PCIe/SSE2" version "3.3.0".

1.1.0 on desktop Windows PC that is five years old and will probably be replaced within the next 18 months.  LDCad could thus become a great incentive to upgrade sooner!

4.4.0 on Asus laptop that is six months old.

[Kevin]

3.3 here, with no graphics driver update available.  I'll probably be replacing this computer in the new future, however.

[Owen Dive]

Version 3.3 here.

[Gerald Lasser]

on my seasoned dell laptop:
OpenGL platform information: vendor "Intel" renderer "Intel® HD Graphics Family" version "3.1.0 - Build 8.15.10.2418".

My Laptop at home:
OpenGL platform information: vendor "Intel" renderer "Intel® HD Graphics 520" version "4.4.0 - Build 20.19.15.4454".

PC at work:
OpenGL platform information: vendor "Intel" renderer "Intel® HD Graphics 4600" version "4.3.0 - Build 10.18.14.4156".

Thanks,

So far 4.x seems much more available then I expected.

1.1.0 on desktop Windows PC that is five years old

That seems wrong, are you sure you have an OpenGL driver from your VGA card maker installed as 1.1 sounds like the default (extremely slow) MS software render-er. you also get when connecting trough remote desktop.

I used to be able to run LEGO Digital Designer on this PC, but after upgrading to Windows 10, LDD failed and no video driver upgrade was available.  That's why I found LDCad and much prefer LDCad to LDD.
