mirrored mode doesn't adapt to changing window size (e.g. fullscreen)

[grrrwaaa]

Hi, this block is awesome, worked right away. One thing:

If I enter fullscreen, the mirror texture is blitted into the backbuffer at the same resolution as the original window, occupying a small fraction of the actual window.

I worked around this by modifying the constructor to use the default display dimensions for the mirror texture,

initializeMirrorTexture(app::getWindow()->getDisplay()->getSize());

and the blit code to respect this difference:

GLint src_w = mMirrorTexture->OGL.Header.TextureSize.w;
GLint src_h = mMirrorTexture->OGL.Header.TextureSize.h;
const ivec2 windowsize = app::getWindowSize();
GLint dst_w = windowsize.x;
GLint dst_h = windowsize.y;
glBlitFramebuffer( 0, src_h, src_w, 0,
0, 0, dst_w, dst_h,
GL_COLOR_BUFFER_BIT, GL_LINEAR );

Seems to work OK, but I'm not sure if this is the ideal solution.

BTW I would also really like to be able to blit the left or right eye texture, because sometimes the mirror screen is better without the Rift distortions etc. applied. Is there a way to do this?

Thanx

Thanks for reporting. The above commit should address this problem. Let me know if that works.

As for the mono mirror texture, I don't think there is a simple solution that doesn't increase rendering costs (i.e. increasing one eye's viewport or rendering the scene a third time). The current mirror texture is provided directly by the SDK.

Note that there is another issue with the mirror texture atm: disabling mirroring will cause flickering in the app's window.

I won't bother fixing it now though, not until they fix the WM_PAINT bug.

Awesome -- I'll check it once I get back to the studio where the DK2 is.

Yes also noted the flickering, but I thought it was something I was doing wrong -- I'm still getting to know Cinder.

About the other texture access, I didn't mean a mono render of the mirror, I mean the texture of the FBO that the scene is rendered into -- would prefer the option to have this undistorted view available on the mirror window rather than the DK2-distorted texture. I mean, the mRenderBuffer->TextureSet texture, rather than the mMirrorFBO texture.

Maybe it can be done already, by blitting from the current draw buffer just before the ScopedRiftBuffer unbinds (before submitFrame)?

@grrrwaaa Got it. And deleted my previous message: looks like this should be allowed by the SDK, at least on the D3D11 with the "Mirror Variants" sample. Maybe your approach would work.
