Thnx BlindSide

What do you exactly mean by saying "deferred shading"?

Hi,

I am writing an editor using irrlicht engine. I came up to constructing "Material Editor".

As irrlicht do not have all the texture/lighting settings (specular texture, specular sharpness (not shinines) etc...) i need to implement this in the editor.

For example to implement a velvet effect, i ...

Hi guys,

These codes rotates the node around local axis, how can i rotate the node around world axis?

Code: Select all

irr::core::matrix4 m;
m.setRotationDegrees(node->getRotation());
irr::core::matrix4 n;
n.setRotationDegrees(rotation);
m *= n;
node->setRotation( m.getRotationDegrees() );

come on guys, help please

scriptr

thanks Serg88 but, that code doesn't rotate the node in its local space. What i am trying to do is far more different than that.

scriptr

unfortunately problem still exists. :shock:

i rotate the node around Y-AXIS 45 degrees. Everything is ok. And then i want to rotate the node around Z-AXIS 45 degrees. Now when i calculate the z unit vector; i get (1,0,1). (I don't use (0,0,1) vector because i want to rotate the node in its local ...

thanks hybrid,

I've managed to make multiplying work. Now, i am trying to rotating the axis vectors, which i use for method fromAngleAxis(), to make the node rotate in its local space. I will paste the code here when finished.

Hi again,

I have found that, i needed to use quaternions. I can now rotate one axis like i wanted but i can not keep the current rotation. I read that i need to create a quaternion with current rotations, and multiply with the newly created rotation quaternion, but that doesn't work.

What could be ...

Hi,

Adding a rotation value to any axis of a scenenode is simple. I do that by the following way;

irr::core::matrix4 m;
m.setRotationDegrees(node->getRotation());
irr::core::matrix4 n;
n.setRotationDegrees(rotation);
m *= n;
node->setRotation( m.getRotationDegrees() );

But, how I can set a ...

scriptr

thank you very much, works perfect!

Code: Select all

_driver->beginScene(true, true, 0);
_smgr->drawAll();
		
_driver->clearZBuffer(); 
transformationArrows->render(); //Render always on top
	  
_driver->endScene();

Hi,

I want add a scenenode and, want it to always render on top of the other scene nodes whereever the camera looks from, even the scenenode is at the back in 3d space. Is this possible?

i've added GetAsyncKeyState control but the compiler gives the following errors:

Error 1 error LNK2028: unresolved token (0A0002EB) "extern "C" short __stdcall GetAsyncKeyState(int)" (?GetAsyncKeyState@@$$J14YGFH@Z) referenced in function "private: void __clrcall IrrlichtManager::run(void)" (?run ...

hi,

i am using irrlicht in windows forms like the way as explained in this thred. But i can not capture "alt key" (especially left alt key) pressed event. Any way to solve this problem?

scriptr

Thanks for your replies.

I have merged my 8 textures in two 1024x1024 picture. And in shader i have clipped and scaled them on terrain without changing any code in irrlicht. Now i can texture my terrain with 8 textures with only three texture channel (2 RGB + 1 Alpha RGB).

scriptr

I have 7-8 different textures and their alpha maps painted on a terrain. And i want to texture my terrain with those textures. As i understood from your reply, that is possible, as no more 4 textures will instersect on the same triangle, right?
