Irrlicht Engine

Faster in a shader, I still need the shader.

I am trying to handle some projection mapping with photon goodness involved. There are some cases where the texture which I need to project does not contain any colour except black.

At the moment I use glsl reduction to check if there are any pixels with colour in them. I was wondering if anyone ...

Is there a faster way to check if an ITexture is a single color other than converting it to an IImage and checking every pixel?

This is a bit off topic to the discussions above but how do we remove a IRenderTarget? Do we just remove the texture in the IRenderTarget like a normal texture?


IVideoDriver* pDriver=(device driver pointer) ;
ITexture rtt*=pDriver->addRenderTargetTexture(...);
IRenderTraget rt=IRenderTarget(rtt ...

I dont think that will work. Here is a textured example.

I have been using a modified version of the texture projection found in http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=31063&highlight=texture+projection but have come across a problem with texture boundaries causing. The same problem exists for shadow mapping but techniques like PCF solve ...

Copy paste fail.

Guess it is wrong. Still having trouble getting comparable results though.

I believed it was that also but debugging my shader says its not (unless my debug code is wrong).

Setting callback

virtual void OnSetConstants(irr::video::IMaterialRendererServices* services,irr::s32 userData)
{
matrix4 world= services->getVideoDriver()->getTransform(video::ETS_PROJECTION ...

I am trying to find the GLSL gl_ModelViewMatrix by multiplying the matrices from getTransfom() but I am getting nowhere.
Debugging shaders is not fun so does anybody know or should i try more multiplying nightmare-inducing code?

I have not read the whole post but what you are trying to do seems alot like Neverwinter Nights ASCII mdl format.

I was looking at the .mdl format and looking at some .mdl viewers, one of which was written in java. Since im using Jirr i wrote a .mdl model loader for Jirr but not using the standard irrlicht interfaces and such.

I was just wondering if anyone would want the code (Im not re-writing in to c++ :P ...

I think either you misunderstood or I explained wrong. (think its the latter :roll: )

I know how to playback animations, the thing I am trying to find out is getting the start frame and end frame without specifying them in code.

I don't want

enum E_ANIM {E_ATTACK, E_RUN};

void function(E ...

This might be a beginner question. :?

I would like to know how would you store and/or get animation sequences from the model like the NWN model viewer ie. how to get the specific models attack animation or stand animation without hardcoding the animation frames for each model and each sequence ...

I love that galaxy view.

Maybe when we mapped out the whole galaxy Solar Model X.0 will be able to zoom in when in galaxy view.

Now the question that appears after every release of anything ever released. *Drum roll* Whats next?

Here is a little motion trail thingy that I found in the beginners forums which I ported to jirr and made it work. Well sort of work because there is no way yet of geting a texture from a material without getting a SWIG_array of textures. Maybe in the next version of jirr we will have that.
