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:
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?
