Re: [Jrman-user] How to use SurfaceClouds.java

[makura <y_m...@ya...>]

Thanks Gerardo, 
it works.

I tried to make a constant shader with java.
but it doesn't work.

folowing : SurfaceFirst.java.
--------------------------

import javax.vecmath.Color3f;

import org.jrman.grid.BooleanGrid;
import org.jrman.grid.Color3fGrid;
import org.jrman.grid.FloatGrid;
import org.jrman.render.ShaderVariables;
import org.jrman.shaders.SurfaceShader;

/*
 SurfaceFirst.java
*/

public class SurfaceFirst extends SurfaceShader {
    
    public void shade(ShaderVariables sv) {
        super.shade(sv);
        sv.Oi.set(sv.Os);
        sv.Ci.mul(sv.Cs, sv.Oi);
    }
}
---------------------------

folowing : a RIB file.
######
#first.rib
Display "first.tif" "framebuffer" "rgb"
Projection "perspective" "fov" [45]
LightSource "ambientlight" 1 "intensity" [0.2]
LightSource "spotlight" 2 "from" [-1 1 0 ] "to" [0 0 3] "intensity" [3]
Translate 0 0 3
WorldBegin
Color [1 0 0]
Surface "First"
Sphere 1 -1 1 360
WorldEnd
#####

C:\jrman-0_4\model>jrman first.rib
Unknown surface shader: First, replacing with fakedlight surface shader
first.rib time: 0h0m7s
Total time: 0h0m7s

it doesn't work.
Can I make a shader?
Where are Shaders directory?

Thank you for your support.
