ospray / ospray_studio Goto Github PK

Hello,
The simple project here attached used to work perfectly with v0.9.0, but now generates a segmentation fault with v0.11.0. Could you please tell what is wrong? Many thanks in advance!

I am testing out the build of ospray studio 0.10.0 on Windows.

I render out the test scene NewSponza with the following command line options

ospray_studio-0.10.0-win64\bin\ospStudio.exe batch --renderer pathtracer NewSponza_Main_Blender_glTF.gltf --image nyue2 --camera 1 --format exr

I get an error about EXR not being supported

#importGLTF(W): mismatching COLOR_0 size
#importGLTF(I): finished import!
Loading camera from index: 1
frame 1 variance inf
No exporter found for type exr
...finished!

I wanted to try out OpenEXR to get better dynamic range of the output colors

It would be helpful to indicate which version of OpenImageIO and OpenEXR has been used successfully with OSPray Studio to save us from version combinatorial explosion to try out when build fails or we encounter problems.

Thank you.

Apparently, imgui used in ospray_studio is not using imgui's support for freetype, so fonts are mis-aligned, and no anti-aliased.

Could something be done about that?

This Project is expected to render a golden cube. Unfortunately, instead, the cube is dark:

I'm using the Principled shader with metallic 1.0, I suspect a problem with it but I can't figure out what's wrong: can someone help me please? Many thanks in advance...

I have been able to build ospray_studio

In the menu, there was option to load some sample scenes but nothing happens.

Do I need to install other packages or set some CMake settings in order for the samples scenes to show up ?

Cheers

When I try to specify camera fovy in sg file, the given value is not taken into account in ospStudio.

The simple file attached below illustrates the issue. It contains only a camera and a light (sunsky). In the camera definition, fovy is set to 90. But in ospStudio, its value remains 60 (default value, presumably).

Could you please tell me what is wrong? Thanks!

This site had some very good still images and panoramas of the Bentley car show room. The metallic materials used on the cars are superior to what Cadalog can render in our new SketchUp plug-in called PodiumxRT. I would really like access to those images and panoramas.

Hi,

I loaded an obj (exported from blender3d) [the monkey.obj], it does not show up in the ospray_studio window.

What am I doing wrong ?

Cheers

Build the head I see the following

When running ospStudoi, it is creating a file called imgui.ini in it.

This is not really nice when no operations have been performed.

Please, consider using XDG_RUNTIME_DIR/.ospray_studio/imgui.ini

Hello,

The attached file merely includes a sunsky and used to work well with v0.9.0. With v0.11.1, however, it will generate an error:

terminate called after throwing an instance of 'std::runtime_error'
  what():  Node::valueAs(): Incorrect type queried for Any
  Node::name() = up
  Node::type() = PARAMETER
  Node::subType() = vec3f
  Node::value() = Any : (currently holds value of type) --> rkcommon::math::vec_t<int, 3, false>
  queried type = rkcommon::math::vec_t<float, 3, false>

Could you please tell me what's wrong with it? Thanks!

Hello,

As stated in the title: if you pass --denoiser in the command line and if you are in GUI mode, no denoising is processed.

I think it's because the floatFormat of the frame buffer is not automatically set to true, unlike in batch mode (https://github.com/ospray/ospray_studio/blob/master/app/Batch.cpp#L322).

--> Could you please have a look and fix it? Many thanks in advance!

By the way, nice-to-have: it would also be convenient to be able from the command line to control whether the denoising is applied for each frame or on final frame only...

I have a i9 with integrated UHD 770 graphics and an ARC 750 running Windows 11 Professional. Ospray Studio does use the i9 and the UHD graphics, but not the ARC 750. Can this be set somewhere?

I have tried to run it with --osm:device=cpu|gpu|default but this only yields "unknown directive" errors.

This Project generates a segmentation fault.
I suspect this is related to the lack of a renderer node in the .sg file in conjunction with the use of a sunSky light (see this code line).
However, this raises two questions:

• Is the renderer node mandatory in the .sg file (and, if so, where is this documented)?
• Shouldn't we expect a more user-friendly message?

Many thanks in advance for your answers!

Steps to reproduce:

1. Launch OSPRay Studio (I'm using 0.8.1 on Win64).
2. Go to Edit -> Lights...
3. Set "type" to "hdri", enter a name, and select an HDRI file. I'm using the Aerodynamics Workshop at 2k resolution.
4. Click "Add" and the HDRI should become visible as a background.
5. Close the "Lights" dialog.
6. Go to File -> Import... and choose a glTF model with text, such as TextureSettingsTest.

The texture coordinates come out flipped, like this:

Here it offers to install all OSPray libraries.

They are already installed as a dependency package, no need to install them again. This would only cause problems.

It appears to copy the whole $PREFIX/lib directory into its lib/ instead of libraries that it itself needs to install.

Dear developers

I am compiling the ospray_studio on an Ubuntu (18.04.1 LTS) laptop (g++ v7.3.0) but fail to link. Here are the error I see:

Windows version, Win10, from zip archive
just add demo scenes

WITH SPHERE
