Do your system provides the OpenGL extension WGL_EXT_create_context_es2_profile
? If it is not supported, you cannot create an OpenGL ES2 context in that way. Maybe you may have success by using ANGLE and EGL.
Include in the working directory the ANGLE pre-compiled libraries (or just compile them yourself): in this way EGL backend should be available (Egl.IsAvailable == true
), and you could require the use of EGL (Egl.IsRequired = true
): in this way the DeviceContext
instance is a DeviceContextEGL
, and it can create GL ES2 contextes (just like HelloTriangle.ANGLE sample does).
Sorry for not providing more data but I don't have enough memory to work with such big solution
Just create a new solution for you, including only the projects you require. Samples and ancillary projects takes lot of RAM. Or just unload unnecessary projects.
I can't find WGL_EXT_create_context_es2_profile
in OpenGL Extensions Viewer 5.1.4. so I tried the ANGLE.
First I tried the sample project from repository. I'm still not sure how I could figure out which projects include referenced libraries so I just removed the references and installed nuget package in sample project. This kind of works in that Egl.IsAvailable
returns true but compilator complained about Matrix4x4f
don't have definition for SetOrtho2D
so I commented out whole call to Gl.UniformMatrix2f
and I'm not sure if that is why nothing is visible one the screen, it's just black.
Then I've tried to use the ANGLE in initial WPF project but with no luck. No matter what I do, the Egl.IsAvailable
returns false. I've changed target framework to net 4.5 and reinstalled nuget packages and Now I got tons of errors like
'Gl' does not contain a definition for 'Color3' GLTest
Before this I've also tried to use KhronosVersion.ApiGl
- this time _DeviceContext.CreateContextAttrib()
returns, giving Gl error "invalid operation"
Hello, I've just started using your project but have problem with basic example. The view is not rendering. As I started investigating it the context is never created and a
NotSupportedException
is thrown atCreateContextAttrib(IntPtr sharedContext, int[] attribsList, KhronosVersion api)
which I missed at fist. Sorry for not providing more data but I don't have enough memory to work with such big solution so I've just compiled my own version ofGLControl
and can't dig any further. The strange thing is that I've tried to explicitly set API version toApiGles2
but the same error is still thrown even if from what I see inDeviceContext
it's should be accepted without any restrictions. Could this error be thrown from some other call? It's hard for me to navigate throught all the methods without having solution loaded.I use OpenGL.Net 0.7.1 OpenGL.Net.WinForms 0.7.1 in WPF Application .NET Framework 4.6.1 (First tried on 4.5 with the same result) Windows 7
