[SOLVED]:SkyX/Caelum and GL 3+, best way forward? Topic is solved

[RevenantStorm]

Ogre Version: 13.6.5
Operating System: Windows 11
Render System: OpenGL/OpenGL 3+

I've nearly finished migrating my project's material scripts from traditional diffuse/specular to PBR, and from using the OpenGL renderer to GL3+.

One of the few remaining tasks is getting the sky to render properly. I have been using SkyX in my project (v0.4.0.7), which still works fine with the OpenGL renderer even though that project seems to have been dead for about a decade. Problem is that when I switch to GL3+, the sky disappears - only the viewport color is visible.

My first guess was shader incompatibility between GL and GL3+. To test, I tried setting gl_FragColor in the SkyX_Skydome.fragment shader to pure magenta, and while that indeed makes the sky magenta with the OpenGL renderer, there's no change on the GL3+ side.

Admittedly, I know next to nothing about shader programming, but I remember reading something about how GL shader matrix order switched from row-major to column-major order at some version. I suspect that would mess with transformations and perhaps translate/scale the skydome such that it is invisible, but given my lack of expertise with shaders, I decided not to follow that rabbit hole and instead take a look at Caelum, as that seems to be the solution the community has thrown its weight behind, and has the distinct advantage of still being supported.

I downloaded and built the Caelum component, and while it also renders correctly with the OpenGL renderer, I ran into a different problem in that it uses Cg shaders, which aside from being old and deprecated technology, don't seem to be entirely supported by GL3+.

That leaves me with three options, as I see it:

• Dig into the SkyX shaders and attempt to figure out what's going on and/or modernize them (unless the problem is glaringly obvious, this could take a while)

• Switch from SkyX to Caelum, convert Caelum Cg shaders to GLSL using a variant of that nVIDIA toolkit/Python script that's been floating around the Internet

• Use one of Ogre's built-in skydomes and say goodbye to volumetric clouds, Rayleigh scattering, day/night cycles and other luxuries

Which option makes the most sense?

Here's the ogre.log from the Caelum sample project:

I can't help you much with this, sorry.

I'm suprised that Caelum is using CG...

The benefit of going the Caelum path is that it would also benefit other people because you could contribute your fixes to the repo, while SkyX has a commercial license.

[RevenantStorm]

That makes two of us!

The benefit of going the Caelum path is that it would also benefit other people because you could contribute your fixes to the repo, while SkyX has a commercial license.

My understanding was that SkyX is LGPL (or at least, the older version I'm working with is)? However, LGPL is more restrictive than MIT, and running a command-line tool to convert the Cg shaders seems like a more viable proposition. So I'll give that a shot and report back.

[eventhorizon]

Which option makes the most sense?

I use Caelum in my project, it somewhat works with OpenGL3+ but the clouds don't work due to them relying on Cg. I basically handle the exceptions and then run with a half-working Caelum haha. The only real solution we have is to move Caelum off of Cg somehow, I've looked into other options but there doesn't seem to be many at the moment.

I recently moved all Caelum code into a separate module (connects with the sim engine hypervisor):
https://github.com/eventhorizon5/skyscr ... vm/sky.cpp

[paroj]

SkyX

probably the shaders use GLSL built-in attributes, which are no longer available with GL3+:
https://ogrecave.github.io/ogre/api/lat ... otoc_md191

watch out for shader compilation errors in the log. When porting between GL3+ and GL1, you might find the UnifiedShader macros handy:
https://ogrecave.github.io/ogre/api/lat ... fiedShader

Caelum

The best way would be to port the Cg shaders to GLSL and then to the UnifiedShader macros. This way the shaders will work on all RenderSystems.

Interesting, that lines up with my experience trying to use clouds in Caelum. Hopefully, we can arrive at a solution that doesn't require swallowing exceptions.

Awesome, thanks! This feels like a nudge in the right direction.

I tried running the nVIDIA cgc utility against some of the Caelum Cg shaders and it seems to spit out GLSL, which is promising.

Predictably, the output is full of gl_* built-ins, which of course means they'll have to be replaced with modern equivalents. I am going to dig into this some more, but in the meantime, I can post the console commands I used to convert the Cg shaders or the output if anyone's interested.

[paroj]

ah.. forgot about that one.

actually, there are "glslf, glslv" cg profiles supported by ogre, which generate glsl code that can then be used by GL3+.

here is an example:
https://github.com/OGRECave/ogre/blob/1 ... .cpp#L5438

[RevenantStorm]

Success on the SkyX side!

The main problem was a single line in the vertex shaders, specifically:

Code: Select all

gl_Position = gl_ModelViewProjectionMatrix * vertex;

which I replaced with:

Code: Select all

uniform mat4 projectionMatrix;
uniform mat4 worldMatrix;
uniform mat4 viewMatrix;
...
gl_Position = projectionMatrix * worldMatrix * viewMatrix * vertex;

and then supplied those matrices as parameters in the material script:

Code: Select all

param_named_auto projectionMatrix projection_matrix
param_named_auto viewMatrix view_matrix
param_named_auto worldMatrix world_matrix

There was also an issue with SkyX_Skydome.fragment calling pow(vec3, float), which the compiler didn't like. So I created a function to raise a vec3 to a power to solve that:

Code: Select all

vec3 powV3(vec3 base, float exponent)
{
	return vec3(pow(base.x, exponent), pow(base.y, exponent), pow(base.z, exponent));
}

It doesn't seem like there's any "official" SkyX repo to submit changes (most of them are years old or single-commit), but at this point it might be better to upload my entire SkyX codebase as I'm pretty sure I've had to make a few other changes for compatibility with modern Ogre (e.g. ms_Singleton, etc.).

Anyway, now that SkyX is handled and I'm emboldened by a relatively easy fix, let me turn my attention back to Caelum.

actually, there are "glslf, glslv" cg profiles supported by ogre, which generate glsl code that can then be used by GL3+.

So the same functionality is built into Ogre? Fascinating. If that also solves the problem of gl_ built-ins, that might be a better approach. Otherwise, I'll continue with running cgc on each of the cg files, extracting GLSL vertex and fragment shaders, and then replace the built-ins.

[scratchyrice]

Nice to see someone else is still using SkyX! Not sure I can be of much help in your case as I have it running with DX11. I have it working with true HDR if you need help with that.

Also have a highly modified multithreaded with multiple LOD version of Hydrax integrated into my engine. I will release it at some point as per the licence requires.

[RevenantStorm]

Not sure I can be of much help in your case as I have it running with DX11. I have it working with true HDR if you need help with that.

No worries, I think I have the OpenGL 3+ side under control, and if I remember correctly, the difference between HDR/LDR is just a #define and additional parameter or two into the shaders. I might even already be using HDR, not sure off the top of my head.

There are still some issues with the moon and lightning modules which I will need to dig into, but those are not an immediate priority as I don't currently use them, and I think they will be relatively simple to fix as I suspect they're probably caused/affected by Ogre API changes since 1.8-1.9.

Also have a highly modified multithreaded with multiple LOD version of Hydrax integrated into my engine. I will release it at some point as per the licence requires.

I might be interested in looking that over at some point as I currently have a barebones unused HydraX integration in my project. Or, see if ogrewater equally meets my needs.

Between our codebases, we probably have a modernized version of the whole SkyX/HydraX suite haha.

[paroj]

note that I have somewhat updated forks of SkyX/ HydraX at:

• https://github.com/paroj/SkyX
• https://github.com/paroj/CommunityHydrax

I did not move them to OGRECave due to licensing (LGPL) differences.

Unfortunately I got no reply from @Xavyiy on any of the channels (mail, twitter) regarding re-licensing to MIT (as was possible with Cealum).

It might be also worth keeping an eye on the efforts by @tritonas00 viewtopic.php?t=97198
which only require one shader for sky and water and thus are much simpler. He wanted to contribute an Ogre Sample at some point, but I dont know what the status is with that..

No worries, I think I have the OpenGL 3+ side under control, and if I remember correctly, the difference between HDR/LDR is just a #define and additional parameter or two into the shaders. I might even already be using HDR, not sure off the top of my head.

In theory, in reality I had to change the shaders as there are multiple points where saturate limits the colour output to 1.0 which you don't want with HDR. I don't think the HDR system was completed.

I might be interested in looking that over at some point as I currently have a barebones unused HydraX integration in my project. Or, see if ogrewater equally meets my needs.

Between our codebases, we probably have a modernized version of the whole SkyX/HydraX suite haha.

Will post the full source at some point as my project will hopefully be commercial and LPGL requires this. As you've probably seen the performance of hydrax is pretty bad. I've implemented an LOD system, and each LOD runs on a separate thread which compiles the necessary data and sends it over to the GPU via OpenCL. This works very well and I get well over 400fps on my system with very high complexity mesh's close to the camera. Some screenshots of it:

Unfortunately I got no reply from @Xavyiy on any of the channels (mail, twitter) regarding re-licensing to MIT (as was possible with Cealum).

Hmm must be a way of contacting him.
