Irrlicht Engine

Hey, that looks really cool! It looks like a class-room where a car race it taking place in the night :)

I laughed a lot about the sentence "failure is not an option"... man this reminds me on my school time ;)

I'm really happy that the IrrIMGUI bindings and the CMake project helps you. At the ...

Hi bkeys,

that are good news :)
Improving the CMake script to find irrlicht automatically sounds like a good idea.

However having IMGUI as a direct submodule inside the IrrIMGUI repository is not perfect from my point of view. Since this could give licence issues (the licences of IMGUI are very ...

Hi,

I tried to use shaders around a half your ago, but Irrlicht is disabling custom shaders (hardcoded) for 2D drawings, so it did not work without changing the irrlicht source a lot. :(

Maybe Irrlicht 1.9 or later versions will support this, It would be really cool... or maybe I will find time in ...

Thanks, I will have a deeper look into it the next days

Thanks for the answer.

Yes of course this must be tested very well.
I just asked because I think about patching it on my local Irrlicht copy.

Do you have a hint where to look for?
Is the main driver file the correct one (for example COpenGLDriver.cpp)? Or is this located in another file.

You ...

Hi Hendu,

I have one other question. You wrote:
The 2d functions prevent using shaders...

Was this a design decision on purpose, because shaders for 2D element would not work correctly with Irrlicht. Or is this somehow a side-effect of the 2D function implementation that was not intended, but ...

Yes with:
(see full code-example above)

Or is there another switch for that?

Hi,

I already set the material type of the 2D override material:


pDriver->getMaterial2D() = Glass;


I also tried to set it directly without assign the prepared Material.
Too bad, that 2D primitives are not supporting this.

I don't want to draw a full screen rect, I just wanted to draw some ...

Hello

I draw some triangles with "draw2DVertexPrimitiveList" and try to set a Material with a Shader.
However the shader is not applied to that triangles, they just use the default solid material type.

This is my code to load the shader:

video::IGPUProgrammingServices * const pGPUService ...

Today I released Version 0.2
Now you can use an Irrlicht High Level driver for drawing the GUI (do not compile with Native OpenGL driver option to use it!).
The new driver has reasonable performance, even if it is must use some workarounds, that are not good for performance.

I will check further if ...

Hi

Thanks for your suggestion. I have not looked at the driver settings so far, but I will check and also checking it on different computers is a good idea.

Best regards,

Hello

For some GUI testes I draw some images in 2D mode to the screen.
They are scaled down and OpenGL filter these images very nice:

But in DirectX9 the same pictures are a little bit crispy:

I switched on ...

I understand this... From my point of view the code change it not very simple, since it might be done at several functions inside the OpenGL driver. Furthermore I don't even know if this is possible or if it will have major drawbacks.
So it is clear, that this might be a risky change, that needs to ...

Hello

I think I found an issue in Irrlicht that is related to clipping planes.

After drawing my 3D scene, I use the function "draw2DVertexPrimitiveList" to draw GUI elements to the screen. For this GUI elements I need some kind of scissoring (Scissor test or something like that). However this is ...

One update from my side here:
In the current version of my IMGUI renderer I just subtract from every vertex -0.375 from X and Y. With this I get a clear and non-blurry text and GUI output, even when Anti-Aliasing is enabled with very high values.

So it seems to be a workaround to compensate the +0 ...
