Irrlicht Engine

hm, obviously I've really got a clever compiler... I tried it again with the memcpy method cvCvtColor( frame, m_AplphaFrame, CV_BGR2BGRA ); // must be set to alpha 255 because in OpenCV it is set to 0 cvSet( m_MaskFrame, cvScalar( 0, 0, 0, 255 ) ); cvAdd( m_AplphaFrame, m_MaskFrame, m_AplphaFrame );...

@hybrid: sorry I don't get why is is possible to set vectors or matrices as parameters in the shaders but not an array of pixel values :-/... is it simply just to big? @Sudi: I thought so too but doing like you say did not lead to more speed; because the memcpy method was even a little more slowly t...

but I have to fill the texture every loop again with the content of the image data, how should I avoid that?

What I like to try right now is to deliver the imageData of the OpenCV Image to the shader to be returned as texture? Is that possible? What I try is: main: ShadManager->convertTexture( conversionNode ); ShadManager: node->setMaterialType( ( E_MATERIAL_TYPE )m_ConversionMaterial ); ShadCallback: Ipl...

pity

oh, I see... I tried to implement it into another project but got strange effects: this room: I did the same I did in your project and got this: http://www.uni-koblenz.de/~awollert/storage/box.jpg http://www.uni-koblenz.de/~awollert/storage/boxGlass.JPG so right now you can hardly see but the glass ...

exactly, I wanted to have such a shiny dwarf like in the demo but unfortunately the dwarf was not included in the source code so I don't know what's wrong here

the glass is wonderful!

how did you give your own mesh the texture? If I include the dwarf and do
my result looks pretty like this:

oh yes, you are right, with an RTT it's really much faster. But I tested it and the while loop is totally as fast as the memcpy, it brings no difference!

ok, maybe this can be moved to snippets because I see that a couple of people tried to convert OpenCV Images to Irrlicht Textures, too, all the same way. Also I don't want to push-up the thread... to first again: I had to convert the OpenCV Image from BGR to BGRA to get it convertible with the textu...

hm, first: memcpy( &texture, &ardata, frame->height*frame->width*frame->depth ); only returns an access violation. second: no I don't because from opencv I don't receive power2-images... third: how do you mean using 2 textures? within the program all commands are executed sequential or not?!...

ok, the mistake was that I had to consider the resulting texture from the shader operation must be EMT_TRANSPARENT_ALPHA_CHANNEL_REF

Hello, I made a billboard covered with a texture where all black parts are transparent. IBillboardSceneNode* videoLeftNode = Smgr->addBillboardSceneNode(0, core::dimension2d<f32>(60, 60), vector3df(0,0,0)); videoLeftNode->setMaterialFlag(video::EMF_LIGHTING, false); videoLeftNode->setMaterialType(vi...

ok, obviously it was the matter of the rendering order... but now I get another problem: if I build my scene and my billboard, give it the texture and draw it the way posted before the black is invisible. But unfortunately all the rest is transparent, too! But I want to have the black invisible and ...

no because in the example there was no need to use it. Beside I also tried it with adding makeColorKeyTexture but it changed nothing.
