瞎玩—Pete's OGL2 PSX Plugin sha…
2005-12-31 15:16 | mazda
嗯，‘瞎玩系列’还是延续到了这方面，这次玩的不是D3D的HLSL而变成OpenGL的GLSL咯……
使用说明。
一：将下列代码分别存为两个文件：gpuPeteOGL2.slv和gpuPeteOGL2.slf
二：将这两个文件存放到一个目录，比如d:\shader下
三：设置Pete's OGL2 PSX GPU Plugins的full screen filters选项，如下图，重点是红框内的内容，shader effects照图中设置，点击后面的"……"按钮，选择上一步的目录。shader level可以根据需要自由选择，越大，效果越强。
四：点击ok，完毕，运行游戏即可
效果——毛玻璃（frosted Glass）

{

return result;
}
void main()
{
// the bigger the shader level, the bigger the texture fetch distance (0,1,2,3)
float fscale = OGL2Param.z*0.8+0.5;
float fbias_x = fscale/OGL2Size.s;
float fbias_y = fscale/OGL2Size.t;
// fetch the neighbor 8 texels, adjusted by the fetch distance
vec4 tmu0=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(-fbias_x,-fbias_y,0.0,0.0));
vec4 tmu1=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(0.0,-fbias_y,0.0,0.0));
vec4 tmu2=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(fbias_x,-fbias_y,0.0,0.0));
vec4 tmu3=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(fbias_x,0.0,0.0,0.0));
vec4 tmu4=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(fbias_x,fbias_y,0.0,0.0));
vec4 tmu5=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(0.0,fbias_y,0.0,0.0));
vec4 tmu6=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(-fbias_x,fbias_y,0.0,0.0));
vec4 tmu7=texture2DProj(OGL2Texture, gl_TexCoord[0] + vec4(-fbias_x,0.0,0.0,0.0));
//generate per-fracgment fake-random value
float frand = fract(gl_TexCoord[1].x*141.141);
frand *= 1431.1431*fract(gl_TexCoord[1].y*131.131);
frand = fract(sqrt(frand+0.3));
// color output
gl_FragColor = colorselect(frand,tmu0,tmu1,tmu2,tmu3,tmu4,tmu5,tmu6,tmu7);
}
//---------------------------------------------
效果如下
以前写的“瞎玩”“瞎写”系列也可以完全移植到这上面。事实上，Pete's的这个plugin的post-processing比MPC要灵活得多啊，呵呵……
