DotNet / Re: Crash on startup when using dock station.

« on: August 11, 2021, 10:42:01 pm »

I have two graphics cards, but with docking station it is three drivers (display adapters).

I checked if cards behave same on dock, so small update:
Without docking station I'm able to run SFML app on both graphic cards.
With docking station I'm able to run SFML app only on integrated card (Intel HD Graphics 630), but not on hi performance (NVIDIA GeForce GTX 1060).

Not sure in what context display adapter for dock stations works (Kensington USB3.0 Video Dock).

All drivers are updated.

I had similar issue (not able to run on hi-perf card when screens are connected by docking station) for one game in beta, but after official release it was working properly.

If its bug in integrated card driver it should not work on both (dock and without dock)
If its bug in hi-perf card it should not work on both (dock and without dock)
If its bug in dock station it should not work when dock station is plugged in.

But it don't work only on dock + hi-perf.

From your perspective it seems that issue is in driver and there is nothing what can be done in SFML?

How can I check with what driver SFML communicating is? It's strange that after connecting docking station (with two screens) Hi-Perf GPU driver start working in different way.

Damn, sounds like a journey.

I had some time this evening so, well, I compiled SFML from source code and that's result:

Code: [Select]

Exception thrown at 0x0000000000000000 in Project1.exe: 0xC0000005: Access violation executing location 0x0000000000000000.

Exception happens in:

WglContext.cpp:402

// Get the pixel format that best matches our requirements
bestFormat = ChoosePixelFormat(deviceContext, &descriptor);

DotNet / Crash on startup when using dock station.

« on: July 27, 2021, 12:14:58 am »

I use USB dock station with 2 monitors attached to it.

When I run app disconnected, it starts and run properly.
When I run app connected, it crash.
When I run app disconnected, then connect after app started, run properly.

internal class Program
{
    public static void Main(string[] args)
    {
         var window = new RenderWindow(new VideoMode(200,200), "test");
    }
}

Graphics / Re: Should I try to adjust SFML or use OpenGL? Missing some 3D features.

Thanks for reply. This whole post was exactly what I was looking for.

Graphics / Should I try to adjust SFML or use OpenGL? Missing some 3D features.

« on: May 05, 2019, 09:20:42 pm »

Hello,

I would like to create a simple project which requires a couple of 3D features.

Basically I need:
1. 3D camera (orthographic)
2. 3D polygons
3. Heightmap

Should I try to adjust SFML? How hard it may be from your experience? Or maybe it would be better to go with pure OpenGL? I really like simplicity of SFML, maybe you know something similar for 3D with mentioned functionalities?

It's not LTBL fault. You have to make one big shape.

But what if you can't? LTBL requires convex shapes so all scene will never be one big shape.

@Daffren, I'm rendering tiles on top of shadows in first case.

@Estivo, this would have worked if the whole labyrinth was one shape but it must be build using convex shapes. It will still makeing bad looking shadows on convex shapes contacting each other.

@Estivo, not exactly does it work the way I wanted.

I give bigger framgnet map and more situations.



1. m_renderLightOverHull false, m_transparency 0, redrawing walls.
Bad: Whole labrinth can be seen, all walls have same brightness.

2. m_renderLightOverHull true, m_transparency 0. 
Bad: Shadows on walls.

3. m_renderLightOverHull true, m_transparency 0.5.
Bad: Shadows on walls, light in separated chamber. 

4. m_renderLightOverHull false, m_transparency 0.
Bad: Walls are unlighted.

5. m_renderLightOverHull false, m_transparency 0.5.
Bad: Walls are unlighted, light in separated chamber.

I'm trying to get situation from picture number 2, but without shadows on wall but still have darkens out of room.

Awww... Still have problems



Does anyone have an idea what to do to get situation from second image instead from first? And situation from third is actual but not satisfactory.

First is when

hull->m_renderLightOverHull = true;

Third is when

hull->m_renderLightOverHull = false;

Of course I can redraw all walls but then I will have all walls visible, also in chambers next to.

Well, I've install that lib and it's work but... Is there any documentation for this lib?

Rendering scene take some time (it's not immediate, take 1-2 seconds to get perfect) that is difference from the last project of this author. It's option to set that scene render immediate? Or this lib have other classes with that functionality? 

@Daffern,
Have same errors but I added all *.dll from sfml and glew32.dll and it's run nice.

It wouldn't be overkill for app? I guess that AABB is render area?

Well... Author probably don't read this topic anymore but I need help so I will risk

in example code from author side everything goes ok but when I change

testLight->m_radius = 600.0f;

to

testLight->m_radius = 20.0f;

(i need little spot light)
I got "Access violation reading location" when mouse moved outside of render window. Visual shows me xhash code on line 1003 so probably something goes wrong in QuadTree in std::unordered_set.

@zsbzsb, hit!

while (true) {
        System::Windows::Forms::Application::DoEvents();
        mainApp.draw();
}
 

This loop is still working after mainApp destruction.

Don't know what to do with this topic. Problem solution have nothing common with SFML Well, thank you all for help.

@Ixrec, nope. Still same.

class B {
        sf::RenderWindow app;
public:
        B( HWND windowHandle ) : app(windowHandle) { }
        void draw() {
                app.clear( sf::Color::White );
                app.display();
        }
        ~B() {
                app.close();
        }
};

I had hope that was fundamental problem. Well... Here is code:
