This one is inspired by the Vista-Taskswitch (i dont know how the topmost window gets to the back, so i created my own way)

PHP Code:
// Taskswitch.tra
// Author - morte0815

float time;
Texture background;

void Init()
{
  time = 0;
  background.LoadTexture("Plasma_edge.jpg");

}

void DrawFrame()
{
  gfxSetTexture(background);
  gfxTexRect(-1.1f, 1.1f, 1.1f, -1.1f);   
}

void TexRect(float top, float bottom, float left, float right, 
float ttop, float tbottom, float tleft, float tright)
{
  gfxBegin(PRIM_QUADLIST);
    gfxTexCoord(tleft,ttop);
    gfxVertex(left,top,0);
    gfxTexCoord(tright,ttop);
    gfxVertex(right,top,0);
    gfxTexCoord(tright,tbottom);
    gfxVertex(right,bottom,0);
    gfxTexCoord(tleft,tbottom);
    gfxVertex(left,bottom,0); 
  gfxEnd();
}

void Render()
{

gfxSetAspect(0);
  time += TIMEPASS;
//   gfxSetBlendMode(BLEND_ADD);
//   float angle = time - 1.5f;
//   if (angle < 0){ angle = -angle;}
//   angle = 1.5f - angle; 
//   gfxRotate(Pow(360,angle*2),0,0,1);
     if (time < 1.0f){
       gfxTranslate(0, 0, 2.414+time*2);
       gfxRotate(-65*time,0,1,0);
       gfxTranslate(0, 0, -time/2.0f);
       gfxPushMatrix();
       
       
       gfxTranslate(0, 0, 1);
       DrawFrame();
       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);
       
       
       gfxPopMatrix();
       
       DrawFrame();
       gfxSetTexture(TEXTURE_CURRPRESET);
       gfxTexRect(-1, 1, 1, -1);
   } 
   if (time > 1.0f && time < 2.0f)
   {
      gfxTranslate(0, 0, 4.414);
      gfxRotate(-65,0,1,0);
      gfxTranslate(0, 0, -0.5f);
       gfxPushMatrix();
       
       gfxTranslate(0, 0, 1-(time-1));
       DrawFrame();
       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);
       
       
       gfxPopMatrix();
       gfxPushMatrix();
       gfxTranslate(0,(time-1)*2,0);
       gfxSetTexture(background);
       TexRect(1.1f,0.0f,-1.1f,1.1f,1.0f,0.5f,0.0f,1.0f);
       gfxSetTexture(TEXTURE_CURRPRESET);
       TexRect(1,0,-1,1,1.0f,0.5f,0.0f,1.0f);
       
       gfxPopMatrix();
       gfxTranslate(0,(1-time)*2,0);
       gfxSetTexture(background);
       TexRect(0.0f,-1.1f,-1.1f,1.1f,0.5f,0.0f,0.0f,1.0f);
       gfxSetTexture(TEXTURE_CURRPRESET);
       TexRect(0,-1,-1,1,0.5f,0.0f,0.0f,1.0f);
   }
    if (time > 2.0f)
   {
      gfxTranslate(0, 0, 4.414-(time-2)*2);
      gfxRotate(-65+(time-2)*65,0,1,0);
      gfxTranslate(0, 0, -0.5f);
       gfxPushMatrix();
       
       DrawFrame();
       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);
      
   }

  if (time>=3){
    FINISHED = true;
  }
        
} 

In this one there is still a bug (the textures tear when the splitted window is shifted away), but i dont know why, so i cant fix it. Maybe someone else finds the bug.

Shocked Outstanding! Shocked

I didn't notice any tearing here.

THANKS!!

You can see the tearing if you use this version (it stops at the splitting of the current visualization):
PHP Code:
// Taskswitch_tearing.tra
// Author - morte0815

float time;
Texture background;

void Init()
{
  time = 0;
  background.LoadTexture("Plasma_edge.jpg");

}

void DrawFrame()
{
  gfxSetTexture(background);
  gfxTexRect(-1.1f, 1.1f, 1.1f, -1.1f);   
}

void TexRect(float top, float bottom, float left, float right, 
float ttop, float tbottom, float tleft, float tright)
{
  gfxBegin(PRIM_QUADLIST);
    gfxTexCoord(tleft,ttop);
    gfxVertex(left,top,0);
    gfxTexCoord(tright,ttop);
    gfxVertex(right,top,0);
    gfxTexCoord(tright,tbottom);
    gfxVertex(right,bottom,0);
    gfxTexCoord(tleft,tbottom);
    gfxVertex(left,bottom,0); 
  gfxEnd();
}

void Render()
{

gfxSetAspect(0);
  time += TIMEPASS;
//   gfxSetBlendMode(BLEND_ADD);
//   float angle = time - 1.5f;
//   if (angle < 0){ angle = -angle;}
//   angle = 1.5f - angle; 
//   gfxRotate(Pow(360,angle*2),0,0,1);
     if (time < 1.0f){
       gfxTranslate(0, 0, 2.414+time*2);
       gfxRotate(-65*time,0,1,0);
       gfxTranslate(0, 0, -time/2.0f);
       gfxPushMatrix();
       
       
       gfxTranslate(0, 0, 1);
       DrawFrame();
       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);

       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);
       
       
       gfxPopMatrix();

       gfxTranslate(0,0,0);
       gfxSetTexture(background);
       TexRect(1.1f,0.0f,-1.1f,1.1f,1.0f,0.5f,0.0f,1.0f);

maybe add some randomness so it does the transition in more than direction ? Smile

Since i cant edit my posts anymore (ADMIN!!!!!!!! Laugh) here is a version with some randomnes:

When it splits the current preset the textures coords are wrong and it draws it upside down. I am not sure if this is the tearing you are talking about or not. Anyway, the fixed version is below. I have also removed a few gfxTranslate functions as it was jumping at the end due to not being at the correct z position. You will probably have a better idea how to fix that than me.

PHP Code:
// Taskswitch.tra
// Author - morte0815

float time;
Texture background;

void Init()
{
  time = 0;
  background.LoadTexture("Plasma_edge.jpg");

}

void DrawFrame()
{
  gfxSetTexture(background);
  gfxTexRect(-1.1f, 1.1f, 1.1f, -1.1f);   
}

void TexRect(float top, float bottom, float left, float right, 
float ttop, float tbottom, float tleft, float tright)
{
  gfxBegin(PRIM_QUADLIST);
    gfxTexCoord(tleft,ttop);
    gfxVertex(left,top,0);
    gfxTexCoord(tright,ttop);
    gfxVertex(right,top,0);
    gfxTexCoord(tright,tbottom);
    gfxVertex(right,bottom,0);
    gfxTexCoord(tleft,tbottom);
    gfxVertex(left,bottom,0); 
  gfxEnd();
}

void Render()
{

gfxSetAspect(0);
  time += TIMEPASS;
//   gfxSetBlendMode(BLEND_ADD);
//   float angle = time - 1.5f;
//   if (angle < 0){ angle = -angle;}
//   angle = 1.5f - angle; 
//   gfxRotate(Pow(360,angle*2),0,0,1);
     if (time < 1.0f){
       gfxTranslate(0, 0, 2.414+time*2);
       gfxRotate(-65*time,0,1,0);
//       gfxTranslate(0, 0, -time/2.0f);
       gfxPushMatrix();
       
       
       gfxTranslate(0, 0, 1);
       DrawFrame();
       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);
       
       
       gfxPopMatrix();
       
       DrawFrame();
       gfxSetTexture(TEXTURE_CURRPRESET);

       gfxTranslate(0, 0, 1-(time-1));
       DrawFrame();
       gfxSetTexture(TEXTURE_NEXTPRESET);
       gfxTexRect(-1, 1, 1, -1);
       
       
       gfxPopMatrix();
       gfxPushMatrix();
       gfxTranslate(0,(time-1)*2,0);
       gfxSetTexture(background);
       TexRect(1.1f,0.0f,-1.1f,1.1f,1.0f,0.5f,0.0f,1.0f);
       gfxSetTexture(TEXTURE_CURRPRESET);
