Huhu,

Eine kleine Frage:

Meinem Terrain konnte ich nun, dank slin, per Farbmaske
einen Shader zu weisen um verschiedene Detailmaps
zumsammenzufuegen.
Das funktioniert auch super mit einer Shadowmap,
so das ich genau 3 Skins habe+ 3 detailmaps.

Nun meine Frage:

Wie kann ich es bewerkstelligen, dass das terrain
nun eine Art Caustics darstellen kann.
(sozusagen der schatten der Wolken...welche sich von
einem ende zum anderen ziehen)

Code:

// multirgb.wdl
// entSkin1 Texture Base
// entSkin2 Texture Layer Red
 
bmap tex1 = <gras.bmp>; // RGB Mask
bmap tex4 = <road.bmp>; // Texture Layer Green
bmap tex5 = <sand.bmp>; // Texture Layer Blue
bmap tex6 = <detailmap.tga>; // DetailMap
 
function multirgb_roughness()
{
bmap_to_mipmap(mtl.Skin1);
bmap_to_mipmap(mtl.Skin2);
bmap_to_mipmap(mtl.Skin3);
bmap_to_mipmap(mtl.Skin4);
}
 
material multirgb
{
flags = tangent;
skin1 = tex1;
skin2 = tex4;
skin3 = tex5;
skin4 = tex6;
 
event = multirgb_roughness;

Im Shader deklarierst du die Skin (wie auch die anderen) und die float4 vecTime; Variable. Dann multiplizierst du den Ausgabefarbwert mit jenem: float cloud_shadows=tex2D(CloudMapSampler,In.Tex1vecTime.w); also FinalColorcloud_shadows; ...wenn das dir zu dunkel wird dann mach einfach Folgendes noch vorher: cloud_shadows=saturate(cloud_shadows+0.4f); oder sowas... Die Idee ist nicht neu aber gut und einfach -z�hlt aber nicht als Kaustiken -> http://de.wikipedia.org/wiki/Kaustik_(Optik)

Dadurch:?"In.Tex1vecTime" Hier mal mein versuch: Code: texture entSkin4; sampler sTex8 = sampler_state { Texture = <entSkin3>; // cloud mask MipFilter = Linear; MinFilter = Linear; MagFilter = Linear; AddressU = Wrap; AddressV = Wrap; }; float cloud_shadows=tex2D(sTex8,In.Tex1vecTime.w); Nur das mit der Matrix versteh ich nicht ganz. Koenntet du mir bitte noch ein wenig helfen? Danke Last edited by Ayumi; 06/13/09 14:51.

So wie eben beschrieben wird vecTime.w gleicherma�en zu den x & y Elementen der Texcoordinaten hinzu addiert, folglicherwei�e wird die Textur schr�g verschoben. Was also auch geht: float speed=0.001f; float T=vecTime.wspeed; [...] In.Tex+float2(1,0)T //-> nur entlang der x-Koordinate In.Tex+float2(0,1)T //-> nur entlang der y-Koordinate oder auch: In.Tex+float2(1,-2)T //->entlang x und mit doppelter Geschwindigkeit r�ckw�rts entlang y (irgendwas schr�ges also) ...wenn du die Richtung per Winkelangabe bestimmen willst geht das irgendwie so: float ang=34;//34 Grad ang=radians(ang); In.Tex+float2(cos(ang),sin(ang))T //-> 34 Grad -> das verschiebt aber nur die Textur um die angegebenen Grad, rotiert sie aber nicht - dazu brauchst du dann noch eine kleine Rotationsmatrix und was wolltest du jetzt noch wegen was f�r einer Matrix? und vergiss nicht im Lite-C Code die neue Bitmap zu deklarieren und die vecTime im Shader(am besten gleich oben bei vecFog und dem ganzen Rest).

So ich habs soweit.

Btw:Das ist C-script, nicht lite-c(Lite-c lern ich gerade^^)

Mhm aber da tut sich nichts.
Was koennte noch fehlen?!?

sTex7 ist die Shadowmap.
sTex8 in dem Fall die clouds.

Code:


// multirgb.wdl
// entSkin1 Texture Base
// entSkin2 Texture Layer Red
 
bmap tex1 = <gras.bmp>; // RGB Mask
bmap tex4 = <road.bmp>; // Texture Layer Green
bmap tex5 = <sand.bmp>; // Texture Layer Blue
bmap tex6 = <detailmap.tga>; // DetailMap
 
function multirgb_roughness()
{
bmap_to_mipmap(mtl.Skin1);
bmap_to_mipmap(mtl.Skin2);
bmap_to_mipmap(mtl.Skin3);
bmap_to_mipmap(mtl.Skin4);

Heyho,

ich habe jetzt eine lange Pause gemacht, und nun such ich mir gerade meine alten Scripte zusammen.Darunter dieser Shader.Nur oberer Code funktioniert nicht mehr und der Fehler liegt irgendwo in diesem Codeblock:

Code:

// pixelshader
	float4 ps( TMULTI_VS_OUT In ) : COLOR
	{
		float4 MaskColor = tex2D(sTex1,In.Tex1);
		float4 BaseColor = tex2D(sTex2,In.Tex2);
		float4 RedColor = tex2D(sTex3,In.Tex3);
		float4 GreenColor = tex2D(sTex4,In.Tex4);
		float4 BlueColor = tex2D(sTex5,In.Tex5);
		float4 DetailColor = tex2D(sTex6,In.Tex5);
	 
		BaseColor = BaseColor + DetailColor - 0.5;
		 
		float4 BaseRed = lerp(BaseColor,RedColor,MaskColor.r);
		float4 BaseGreen = lerp(BaseRed,GreenColor,MaskColor.g);
		float4 FinalColor = lerp(BaseGreen,BlueColor,MaskColor.b);
		FinalColor = (FinalColor+FinalColor*In.sun)/2;
		FinalColor *= tex2D(sTex7, In.Tex1);
		
		float speed=0.01f;
		float sTex8=tex2D(sTex8,In.Tex1+vecTime.w*speed);
		FinalColor*=sTex8;
		
		FinalColor.a = 1.0f; // prevent transparency
		
		return FinalColor;
	}

Fehlermeldungen sind:

Danke.
