Irrlicht Engine

Oh... I didn't see it. So it is. Thanks

I went through the EffectHandler, seems the screenResolution is already sent to the shader :oops:

sPP.addShaderDefine("SCREENX", core::stringc(ScreenRTTSize.Width));
sPP.addShaderDefine("SCREENY", core::stringc(ScreenRTTSize.Height));

My bad...

However, I am wondering how outlines can be ...

It will be great that irrlicht can render bezier surface & mesh.

XEffects and render to depth map then add a post processing effect that compares the depth of different pixels and makes them dark if theres a reasonable difference, quite similar to simple ssao shader

by different pixels, do you mean the neighbouring 8 pixels depth? If so, I also checked out the ...

Hey, Blindside, I tried out the SSAO postprocess shader. It is great though I find a region consisting of white lines.

The white lines will change its orientations when changing view positions and angles.

I tried to set different ...

Yes, accuracy of UV calculations are causing the problem. I have been thinking of ways to adjust the UVs like

if(UV < 0.1) UV += epsilon;
if(UV > 0.9) UV -= epsilon;

Although it will eliminate the black border, the result is not realistic and still can clearly see the border difference.

The mesh ...

Hi BlindSide,

Thank you for the reply... Yes, I am using per face normals.. and for the above cases. The mesh is just a simple hillplanemesh with 3x3 resolution. I think the normals are all vector3df(0,1,0) for both vertices and faces. The light is positioned at vector3df(0,4000,0). Each light map ...

Dear all,

I implemented the lightmap calculation algorithm. It kinda works.

1. I create a individual mesh.

2. for each face of the original mesh,

2a. I create a meshbuffer and add to the new mesh
using 'S3DVertex2TCoords' for each vertice.

2b. I calculate the light map UV coordinates and ...

No, it doesn't compile... It is my test for cubemapping though... Finally It turned out I had to use IDirect3DCubeTexture9 as texCube only accept cubemaps.

Cannot wait for the coming version... I will try the 1st method of the clipping... Thanks, genius

I have been playing with XEffects for a while. It is awesome.. just awesome, however, there are some potential revisions that should be taken in consideration.

1. In the function "removeShadowFromNode", the while loop statement should be changed to


while(i < ShadowNodeArray.size ...

Hi guys,

I am trying to implement a cg shader that use only 1 sampler2D map (all 6 faces of the cube map are combined into this map in a certain order). The purpose is to use render to target technique. Set all 6 different size of viewports of the 6 directions of the camera to create such sampler2D ...

Thanks BlindSide & zillion42 ... It is indeed the vertex shader caused the corription... Moving calculation of UV to frag shader just solved the problem... Thanks for the tip...
