Try adding another glLoadIdentity() just after the glMatrixMode(GL_MODELVIEW) command.

It crashes when blitting just depth too. I added the stencil bit thinking maybe the problem was with blitting just one half of the packed...

Don't you think this make more sense : void CopenGLCoordView::DrawScene(CDC *pDC) { wglMakeCurrent(pDC->m_hDC, m_hrc); ...

I am trying so that my line from drawLine should not rotate. Others should rotate. But with the below code nothing is rotating. I knew that we can...

Okay sorry for the late answer ^^ i was a little busy please i really need help with assimp it's impossible to use any example source code it says...

Here is one explanation for Windows http://www.opengl.org/wiki/FAQ#How_Does_It_Work_On_Windows.3F

You forgot to use glGetError(). You are using the projection matrix stack which tends to be not very deep. There is maybe a stack space of 2 or 4...

It probably wouldn't have a "serious" impact on performance, but it would have. It's not really about the extra if-checks, but the fact that if you...

Ok, I have one more question. Is it possible to clear only one texture this way ?: glBindFramebuffer(GL_FRAMEBUFFER, fbo); glDrawBuffers(1,...

Yeah, with orthographic projections, you don't have an eye "point". The eye rays don't converge to a point like they do perspective. You actually...

Yes. Once you're coding in shaders, you'll see that that CLIP-SPACE may be the only space in which the GPU receives your vertex positions.

Yes, ::MessageBoxA() makes the same problem. The problem lies in the way MessageBox is implemented in combination with debug_output. MessageBox send...

try blitting depth and stencil separately in two glBlitFramebuffer calls. if it works, report here a driver bug. i've already seen topics mentioning...

In general, unless you're throwing a pointer at the implementation, a crash is always a driver bug.

Thanks for that

I don't own the code so I don't feel comfortable sharing it here. But i can say that I am definitely not loading the textures every time. It is done...

Hi, perfect place to start. Follow it STEP BY STEP ... and you are fine: http://www.swiftless.com/tutorials/opengl/window.html cu kai

OpenGL is a graphics API. It is built in graphics driver, which is, of course, highly dependant on the operating system. There is a Mesa3D solution,...

Whops! Sometimes you miss the obvious! Of course you're right. I still need the frametime, but at "position += velocity * frametime;". Thanks alot...

I think that your position should not be multiplied by frame time. The code should be like this: modelMatrix =...

I can appreciate the point of view that swizzling is not sampler state, but I utterly disagree. Call me stubborn, or something else:p. I generally...
