Ogre shader usage

For the usage of ogre shader, refer to the two instructions:

I tried it myself.

 

// Create scenemanager and camera
Ogre: scenemanager * Sm = RT-> createscenemanager (Ogre: st_generic, "testscence ");

// Shader
If (Ogre: rtshader: shadergenerator: Initialize ()){

Ogre: rtshader: shadergenerator * mshadergenerator = ogre: rtshader: shadergenerator: getsingletonptr ();
Mshadergenerator-> setshadercachepath ("C: \ Download \ OgreSDK_vc10_v1-8-1 \ media \ rtshaderlib \ cache ");
Mshadergenerator-> addscenemanager (SM );
}

 

Set the shader material.

Ogre: entity * ET = Sm-> createentity ("robot. mesh ");
// Ogre: resourcegroupmanager: getsingleton (). Create
Et-> setmaterial (Ogre: materialmanager: getsingleton (). getbyname ("RTSs/layeredblending"); // This is defined in the material script. The file is in the shaderlib folder under ogre media.
Ogre: scenenode * node = Sm-> getrootscenenode ()-> createchildscenenode (Ogre: vector3 (0, 0 ));
Node-> attachobject (ET );
Node-> Roll (Ogre: radian (0.9 ));
Node-> Scale (1, 1, 3 );

An error occurred while running. The resource was not added.

Ogre: resourcegroupmanager: getsingleton (). addresourcelocation (
"C: \ Download \ OgreSDK_vc10_v1-8-1 \ media \ rtshaderlib"
, "Filesystem"
, "Rtshaderlib ");

Ogre: resourcegroupmanager: getsingleton (). addresourcelocation (
"C: \ Download \ OgreSDK_vc10_v1-8-1 \ media \ rtshaderlib \ materials"
, "Filesystem"
, "Rtshaderlib ");

After joining the program, the program runs successfully. The robot was previously completely yellow and now it is striped.
