New release avalaible!
Added some simple shaders to the ships and planets, and replaced the billboard engine glows with good old fashioned particles. I also included my work in progress space ship.
[EDIT] 11-02-06- Looks like this version of the shuttle used Marc's textures as well, which was not noted in the license.txt file. Sorry about that.
A picture is worth a thousand words:
Since this release I also managed to convert the Rendermonkey Earth shader to cg, and it looks AWESOME:
Code: Select all
void vert(
float2 uv : TEXCOORD0,
out float2 oUv : TEXCOORD4,
float4 position : POSITION,
float3 normal : NORMAL,
uniform float4 lightPosition,
uniform float3 eyePosition,
uniform float4x4 worldviewproj,
out float4 oPos : POSITION,
out float3 oNorm: TEXCOORD0,
out float3 oLightDir: TEXCOORD1,
out float3 oHalfAngle: TEXCOORD2
)
{
oUv = uv;
oPos = mul(worldviewproj, position);
float3 EyeDir = normalize(eyePosition - position.xyz);
oLightDir = normalize(lightPosition.xyz - (position.xyz * lightPosition.w));
oHalfAngle = normalize(oLightDir + EyeDir);
oNorm = normal;
}
float3 expand(float3 v)
{
return (v - 0.5) * 2;
}
float3 mix(float3 x, float3 y, float3 a)
{
return x * (1.0 - a) + y * a;
}
void frag(
float3 normal: TEXCOORD0,
float3 LightDir : TEXCOORD1,
float3 HalfAngle : TEXCOORD2,
//cloud status(0 none, 1, has), spec exponent, spec intensity.
uniform float3 specVals,
//glow factor for the night side.
uniform float4 nightBlend,
//ADDED BY EUGEN - support for texture with the per pixel lighting
float2 uv : TEXCOORD4,
//these are going to be combined into two maps soon.
uniform sampler2D texture : register(s0),
//map of city lights
uniform sampler2D lightMap : register(s1),
//specular and cloud map
uniform sampler2D cloudMap : register(s2),
uniform float4 ambient,
out float4 oColor : COLOR
)
{
float Terminator = 0.3;
float InvTerminator = 1.0 / (2.0 * Terminator);
float3 textColour = expand(tex2D(texture, uv).xyz);
float3 nightLights = expand(tex2D(lightMap, uv).xyz);
float clouds = tex2D(cloudMap, uv).x;;
float specVal = tex2D(cloudMap, uv).y;
float3 N = normalize(normal);
float NdotL = dot(LightDir, N);
float NdotH = dot(HalfAngle, N);
float4 Lit = lit(NdotL/1.35, NdotH, specVals.y);
float3 dayTime = (0,0,0);
float3 nightTime = dayTime;
if (Lit.y > 0)
{
dayTime = textColour * Lit.y + (specVals.z * Lit.z);
dayTime = mix(dayTime, abs(Lit.y), float3(clouds, clouds, clouds)) + ambient;
}
if (Lit.y < 0.4)
{
nightTime = nightLights * (1.0 - clouds) + nightBlend ;
}
if (Lit.y >= 0.4)
oColor = float4(dayTime, 1) ;
else if (Lit.y < 0.4 && Lit.y > 0)
{
oColor = float4(mix(nightTime - ambient, dayTime , (Lit.y + 0.4) * (1 /(2 *0.4))), 1);
}
else
oColor = float4(nightTime, 1);
}
[EDIT] just noticed that the first specVals member isn't being used. It was going to be used to determine whether there were going to be clouds or not, but decided to just edit the textures to compensate.
I also altered the render-system plugins to allow the user to change whether shaders are used in the game or not via the config box. I found the code to be slightly confusing but very, very, well organized.
I will be uploading the altered files to my CVS soon.
Cegui just came off as being too much for what I needed, way too much.
This is not working right. I just copyped the data files over.
