Pencil Drawing Shader

[franck22000]

Here is a new shader that i made for LE, Pencil Drawing Shader

 

Just put this piece of code in the postfilter.frag shader in the end of the main() function just before "gl_FragColor = outputcolor;"

 

 

       float dpt=0;
dpt+=texture2D( texture1, texcoord + vec2(	0,	pixelsize.y * 2.0	)).x;
dpt+=texture2D( texture1, texcoord - vec2(	0,	pixelsize.y * 2.0	)).x;
dpt+=texture2D( texture1, texcoord + vec2(	pixelsize.x * 2.0,	0	)).x;
dpt+=texture2D( texture1, texcoord - vec2(	pixelsize.x * 2.0,	0	)).x;
dpt/=4;

if ((depth-dpt)>0.0001) 
{
	outputcolor=vec4(0.05,0.05,0.05,1.0); // Edges color
}
else
{

  vec4 c = texture2D(texture0,texcoord);

  c += texture2D(texture0, texcoord+0.001);
  c += texture2D(texture0, texcoord+0.002);
  c += texture2D(texture0, texcoord+0.003);
  c += texture2D(texture0, texcoord+0.004);
  c += texture2D(texture0, texcoord+0.005);
  c += texture2D(texture0, texcoord+0.006);

  c.rgb = vec3((c.r+c.g+c.B)/2.0);
  vec4 graycolor = vec4(0.15,0.15,0.15,1.0);

outputcolor=c*graycolor;
}

It would be awesome if it didn't lose detail/definition (if you get what I mean).

This is very cool, and I'm glad you posted this here; it just gave me a great idea for a game.
