i search for a good Outline Shader - So that i draw the Outline of my Mesh. I don't need complete Toon Shading or things like that. Just a Outline from my Mesh.
I have found this paper:
http://blogs.aerys.i...g/#comment-1593
And i have try to implement it in AGAL, with this Result:
va0 = VertexPosition
va3 = VertexNormal
vc0 = WorldToScreenMatrix
vc4 = CameraPosition
vc20 = Constants (.y = 0.04)
vertexShaderAssemblerColor.assemble(Context3DProgramType.VERTEX,
"sub vt0, va0,vc4\n" +
"dp3 vt1, va3, vt0\n" +
"slt vt2, vc20.x,vt1\n" +
"mov vt3, vc20.y\n" +
"mul vt4, vt2, va3.xyz\n" +
"mul vt4, vt4, vt3\n" +
"add vt5, va0, vt4\n"+
"m44 op ,vt5 vc0\n"
fc20 = Constants,x= 0.1
fc8 = Color
Context3DProgramType.FRAGMENT,
"tex ft0 v1 fs0<2d,linear,repeat,linear,mipnone>\n" +
"slt ft1 v4.x fc20.x\n" +
"mul ft2 ft1 fc8\n"
so, but there nothing happens - Or a white screen. Have somebody some cool Outline Shader or know what is wrong with my?
