Cainiao learn ogre and tianlong Babu 13th: bloom full screen soft light

After searching for the CG file, you can find the file,

The full screen softening effect of the bloom implemented by the shader is a bit obscure, and it doesn't feel clear about the vortex.

It's too vague to mix twice. We should make it blur, ghost

This FPS drops so fast...

 

 

Because Sohu does not provide synthesizer scripts, we need to implement Synthesizer by code.

 

I developed my own source code, fuzzy version:

// Bloom <br/> compositorptr comp = compositormanager: getsingleton (). create ("bloom", "tlbb"); <br/>{< br/> compositiontechnique * t = comp-> createtechnique (); <br/>{< br/> compositiontechnique: texturedefinition * def = T-> createtexturedefinition ("rt0"); <br/> def-> width = 0; <br/> def-> Height = 0; <br/> def-> Format = pf_r8g8b8; <br/>}< br/>{< br/> compositiontechnique :: texturedefinition * def = T-> createtexturedefinition ("rt1"); <br/> def-> width = 0; <br/> def-> Height = 0; <br/> def-> Format = pf_r8g8b8; <br/>}< br/>{< br/> compositiontechnique :: texturedefinition * def = T-> createtexturedefinition ("rt2"); <br/> def-> width = 0; <br/> def-> Height = 0; <br/> def-> Format = pf_r8g8b8; <br/>}< br/>{< br/> compositiontargetpass * TP = T-> createtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_previous); <br/> TP-> setoutputname ("rt1 "); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> createtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_previous ); <br/> TP-> setoutputname ("rt2"); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> createtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_none); <br/> TP-> setoutputname ("rt0 "); <br/> compositionpass * pass = TP-> createpass (); <br/> pass-> settype (compositionpass: pt_renderquad ); <br/> pass-> setmaterialname ("postfilters/bloom/blur"); <br/> pass-> setinput (0, "rt1 "); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> createtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_none ); <br/> TP-> setoutputname ("rt1"); <br/> compositionpass * pass = TP-> createpass (); <br/> pass-> settype (compositionpass:: pt_renderquad); <br/> pass-> setmaterialname ("postfilters/bloom/blur"); <br/> pass-> setinput (0, "rt0 "); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> getoutputtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_none ); <br/> {compositionpass * pass = TP-> createpass (); <br/> pass-> settype (compositionpass: pt_renderquad ); <br/> pass-> setmaterialname ("postfilters/bloom/FINAL"); <br/> pass-> setinput (0, "rt2 "); <br/> pass-> setinput (1, "rt1"); <br/>}< br/>}

 

// Do it once, clear a lot:

 

// Bloom <br/> compositorptr comp = compositormanager: getsingleton (). create ("bloom", "tlbb"); <br/>{< br/> compositiontechnique * t = comp-> createtechnique (); <br/>{< br/> compositiontechnique: texturedefinition * def = T-> createtexturedefinition ("<input> "); <br/>}< br/>{< br/> compositiontechnique: texturedefinition * def = T-> createtexturedefinition ("<input1> "); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> createtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_previous ); <br/> TP-> setoutputname ("<input> "); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> createtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_none ); <br/> TP-> setoutputname ("<input1>"); <br/> compositionpass * pass = TP-> createpass (); <br/> pass-> settype (compositionpass: pt_renderquad); <br/> pass-> setmaterialname ("postfilters/bloom/blur "); <br/> pass-> setinput (0, "<input> "); <br/>}< br/>{< br/> compositiontargetpass * TP = T-> getoutputtargetpass (); <br/> TP-> setinputmode (compositiontargetpass: im_none ); <br/> {compositionpass * pass = TP-> createpass (); <br/> pass-> settype (compositionpass: pt_renderquad ); <br/> pass-> setmaterialname ("postfilters/bloom/FINAL"); <br/> pass-> setinput (0, "<input1> "); <br/> pass-> setinput (1, "<input>"); <br/>}< br/>}
