Irrlicht Engine

Hi slavik262

the second case is what i need,thank you very much!

Hi,

someone can tell me how can i know if a scene node is visible before draw the scene?it's very important for me!

thx

Hi all,

I've tried to use EMT_SPHERE_MAP material,my model is a teapot,texture is given by irrlicht/media/spheremap.jpg,driver is ogl.But the effect is very bad.I'd like to know if i've made some errors?Anything else to do to use sphere mapping except to assign the material type.

Hello everyone,

i've construct a big scene,for some special reasons,i need to modify the near value of camera.but i find it doesn't work like what i expect.
This is my experiment:
set camera position: -21690.0f, 3000.0f, -25938.0f
set camera target :-21690.0f, 1.0000f, -25938.0f
there is a plane ...

It's a very strange problem.
When i load my scene graph exported by irrEdit,named "a.irr",it always gave the error" Could not load mesh, because file could not be opened: : boundingbox.obj "
I'm sure there are no path problems,what's the reason?
BTW,if only custom scene nodes by irrEdit like cube ...

Uppload your images somewhere else like imageshack.us
those links don't even work when I copy,paste them.

Oh,yes this time i upload the images to flickr,i hope you can see them.

A bit more supplyment,
only when the RTT texture generation i set the larger clipping value,alternate i would change it back to render my scene use small value.

Hello,

My question is about setNearValue() function.My scene is very large,so distances between objects is a bit far.When i use RTT(render to texture) effects,sometimes i must put carmera far away from viewport,so i should set a larger Znear value,using camera->setNearValue(),then artifacts ...

Thank you very much!

GLSL
uniform vec4 waveData[5];

irrlicht
f32 waveData[20] = {0.766f,0.643f,200.0f,2.0f,
0.174f,0.985f,240.0f,2.4f,
-0.985f,0.174f,184.0f,1.82f,
-0.643f,-0.766f,120.0f,1.2f,
0.174f,-0.985f,160.0f,1.6f};

services->setVertexShaderConstant("waveData",waveData,20);

It works ...

In my shader,uniform array like this was used:
uniform vec4 WaveData[5];
i found irrlicht can not initialize this array,just only vector waveData[0] could be set using:setVertexShaderConstant() function.
so in my opinion,i must declare like:
uniform matrix4 waveData1;
uniform vector4 waveData2 ...

hoho,
problem is solved,it's my mistake.
By default irrlicht forbidden z-buffer of transparent material.
just adding:
smgr->getParameters()->setAttribute(scene::ALLOW_ZWRITE_ON_TRANSPARENT,true);

That's all right!

Hello folks,

i's using irrlicht to build my scene,for trees models there's one artifact.The tree trunks are solid and the leaves are defined as
"trans_alphach" type,and the textures for leaves are tga format which support alpha chanal transparence.The artifact is that we could see other tree ...

Hello,
In shader language i don't know how to pass variables to struct uniform,please look the codes below,color messages can not be passed to Lighting struct.Anyone knows how to make it working?

Thank you!

pixel shader:

struct Lighting
{
float R;
float G;
float B;
};
uniform Lighting L ...

wow,i mean it displays like "…………FPS：@#！"
19 could not be displayed.

No i've traced the code step by step,it's not zero.and fps is 19.
