Quick 'n Dirty SkyManager: day/night transitions + suns

This is just a simple way to get Day/Night transitions into your program
* The sky's brightness is influenced by the position of the sun
* The sky is animated
* You can add as many suns/comets as you like, all with different orbits
* Night time has its own lighting, so you can still see even if there are no suns in the sky
* Particle effects are automatically generated based on the star properties you give
* You can get it working with just 3 lines of code

See the included Readme file for more info, and post screenshots if you use this for anything :)

Thats really cool, thanks!, I re-wrote it in python, and have included it in the python-ogre techdemo project, some shots are here.

I've kept your copyright of course, but please say if you dont want it used in the demo.

Once again, thanks for this simple solution :)

Really cool, good job there. You should think about collaborating with Kencho on Caelum!

I'm just happy to see it being used! Especially to see it behind some good looking terrain instead of the crappy flat plane I was using. I'm not sure what your shadow problem is, but the first thing I would try is setting directionalStars to false in the init call.

Nah... the reason why mine is so basic is because my knowledge of Ogre is still pretty basic =p The sky shader was supplied by HexiDave and the particle effect was done by Mansur; I just wrote the code to mix them together and make it easy to use.

Thanks though... and thanks to KungFooMasta too :)

i get an exception, log says
Code: Select all
01:29:05: WARNING: material SkydomeShaderBlend has no supportable Techniques and will be blank. Explanation: 
Pass 0: Vertex program skydomeVS cannot be used - not supported.


Does my graphic card not support the shader?

I would have thought the geforce 6800gs would be up to the task since it has support for Shader Model 3.0, Pixel Shader 3.0 and Vertex Shader 3.0. I'm not sure why it doesn't like the shader sorry.

Yeah, I'm now getting the same kind of thing after upgrading to the latest Ogre version. Seems something has changed in shader compilation from 1.4.0 - 1.4.2. If anyone can shed any light I'm sure we'd all be very grateful :)

From having suffered something similar in the past, make sure your targets/profiles are set properly in the vertex/fragment references in the Material file.

And check the ogre.log for the compile error.

I accidentally updated the Dx SDK to April 2007 in 1.4.2 and the HLSL compiler has dropped support for SM1 shaders. Change them to Cg to resolve this which still supports SM1. It's just a case of changing the language code to cg and 'target' to 'profiles' (and you can add a GL profile in there if you like)

Firstly, apologies I know this is the wrong thread for questions, but I did not want to start a new topic. So I had a tab at what sinbad suggests, here is my best effort, of course it does not work :?

if anyone can help, please do :)

first: material file:

Code: Select all
fragment_program skydomePS hlsl
{
   source sky_vp.cg
   profile ps_1_4
   entry_point sky_vs
}

vertex_program skydomeVS hlsl
{
   source sky_fp.cg
   profile vs_1_1
   entry_point sky_ps
}

material SkydomeShaderBlend
{
   technique
   {
      pass
      {
         fragment_program_ref skydomePS
         {
            //Shader Constant: fBlend
            param_named fBlend float 0.000000
         }

         vertex_program_ref skydomeVS
         {
            //Shader Constant: matViewProjection
            param_named_auto matViewProjection viewproj_matrix

            //Shader Constant: fAnimSpeed
            param_named fAnimSpeed float2 -5.0 2.5

            //Shader Constant: fTime0_1
            param_named_auto fTime0_1 time_0_1 120.0
            param_named fTexScales float4 3.0 3.0 5.0 5.0
         }

         texture_unit
         {
            texture nightcloud2.png 2d
         }
         texture_unit
         {
            texture daycloud.png 2d
         }
      }
   }
}


heres my attempt at translating the vertex prog:

Code: Select all
/* SkyManager VP - Cg version */

void sky_vs (   float4 Position : POSITION,
         float2 TexCoord : TEXCOORD0,

         out float4 pos : POSITION,
         out float2 tex0 : TEXCOORD0
         out float2 tex1 : TEXCOORD1

         uniform float4x4 worldViewProj,
         uniform float2 fAnimSpeed,
         uniform float fTime0_1,
         uniform float4 fTexScales   )
{
pos = mul( worldViewProj, Position );
float2 animBonus = float2(fAnimSpeed.x, fAnimSpeed.y)*fTime0_1;

tex0 = float2(TexCoord.x * 1/fTexScales.x, TexCoord.y * 1/fTexScales.y) + fAnimBonus;
tex1 = float2(TexCoord.x * 1/fTexScales.z, TexCoord.y * 1/fTexScales.w) + fAnimBonus;
}


and my increasingly pitiful attempt at the fragment prog translation...

Code: Select all
/* SkyManager FP - Cg version */

void sky_ps (   
         float2 TexCoord0 : TEXCOORD0,
         float2 TexCoord1 : TEXCOORD1,

         uniform float fBlend,

         uniform sampler2D Texture0 : register(s0),
         uniform sampler2D Texture1 : register(s1),

         out float4 col : COLOR0      )

{
float4 tex0 = tex2D(Texture0, TexCoord0);
float4 tex1 = tex3D(Texture0, TexCoord1;

col = ( lerp (tex0, tex1, fBlend ) );
}


Once again apologies for the 'supporty' post, and my rather obvious inexperience with SL.[/code]

I accidentally updated the Dx SDK to April 2007 in 1.4.2 and the HLSL compiler has dropped support for SM1 shaders. Change them to Cg to resolve this which still supports SM1. It's just a case of changing the language code to cg and 'target' to 'profiles' (and you can add a GL profile in there if you like)


The solution is really simple:

In the sky.material file change line 5 'target ps_1_4' to 'target ps_2_0'. The shader runs fine in a 2.0 enviroment.

Also, make sure your far clipping value is large enough(like 7000 or so: _Camera->setFarClipDistance( 7000 ); ). I was wondering why I couldnt see anything... found out my far clipping was set to 100 :oops:
I have not failed... I've just found many ways that wont work

Re: Quick 'n Dirty SkyManager: day/night transitions + suns

Postby EmCoMa » Wed Dec 09, 2009 10:24 am

Hello everybody! I have a problem with the code of SkyManager. At runtime happens this exception:

Named constants have not been initialised, perhaps a compile error .in GpuProgramParameters::_findNamedConstantDefinition at f:\codingextra\ogre\shoggoth_vc9\ogre\ogramain\src\ogregpuprogram.cpp (line 1087)

What should I do to solve this problem?

Thanks in advance!!! :D

1. You should try SkyX which is a very good and feature-rich Sky-Plugin for Ogre. Search the forum for it.
2. Concerning your crash: Have a look at the Ogre.log. There is some problem with the shaders where a parameter is requested but not given / wrongly spelled or something similar.
