Irrlicht Engine

So it is indeed a bug in the Direct3D driver?

Before I moved this into the bugs forum, can anybody confirm to me that createScreenShot actually captures any overlapping window above the Irrlicht drawing surface.

For example, I have an application (windowed, non-fullscreen) that used Irrlicht to perform 3D rendering. I want to save the 3D ...

How do I calculate a targeting box in screen coordinates that encloses an object? For example, in flight simulator, whenever you saw a bogie in front of you, you have a targeting box in your HUD that encloses the enemy ship. I want to achieve the same.

Thanks in advance.

Any quick patch to this?

Thanks Hybrid, but no luck either. I tried to call remove texture before dropping it, like the followings


if (++count == 500)
{
rt = driver->createRenderTargetTexture(core::dimension2d<s32>(256,256));

// Comment the following 2 lines and things will be ok.
rt->lock();
rt->unlock ...

Ok, just did a quick test. I tried making the texture above has a dimension of 1024 x 1024 by padding extra space, and it still looks yucky. Can't see any significant improvements than before.

I just got a feeling that whether it could be the texture anti-aliasing works better without alpha ...

Thanks for all inputs. Appreciate them!

BlindSide's solution seems very creative, though requires great deal of precision in order to be precise.

For the rest, I am not sure whether the rendering quality is indeed caused by non-POT texture dimension. As you can seen from my tests above, both ...

Sorry I noticed that the MipMap flag is activated. I had disabled it and update the screenshots above. Still looks somewhat unsatifactory.

Thanks for the quick response. I wish I can scale the texture size into power of 2, but it is not possible in my case, as the image is specified by the user, the most I can do is scaling either its Width or Height to be power of 2, and the other dimension will have to scale proportionally.

Thus, I ...

Hi,

If I had an image that contains line networks, that looks like below,

what is the best way of apply this type image as texture on a 3D plane that will give the most optimum appearance? Note that the white color area supposed to be transparent ...

No comments, anyone? Hmmm....

Hmm... I wonder when this problem will be fixed? (Or will it ever be fixed.)

Thanks Hybrid for the effort. Anyway, what are those extra "additions" that are missing? Like curve, circle entities, etc. in DXF I supposed?

Also, does your DXF loader draw the lines only, or it will fill them with solid colors?

Hi,

While I was looking for DXF loader for Irrlicht, I found this patch at Hybrid website,

http://parsys.informatik.uni-oldenburg.de/~hybrid/irrlicht/patch.1.0/features/addfiles/dxf.patch

Why does this patch never make it to the official release? Wondering whether it is still usable for the ...

Aside from that, I also noticed createScreenShot will capture any windows that are on top of the main window where Irrlicht renders. This might not be a problem in fullscreen mode, but I believe it is ill-suited for programs in windowed mode, where there is always dialog boxes (of the same ...
