GuiObjectView Rotation fix

by Glenn Bermingham · 10/16/2013 (5:23 pm) · 5 comments

Not my findings but I thought I'd share this in a resource form.


In Engine/T3D/guiObjectView.cpp
Change:
mCameraRot.set( 0.0f, 0.0f, 3.9f );  
  mCameraPos.set( 0.0f, 1.75f, 1.25f );
to
mCameraRot.set( 0.0f, 0.0f, 0.0f );  
  mCameraPos.set( 0.0f, 0.0f, 0.0f );

then change
SceneRenderState state    
       (    
          gClientSceneGraph,    
          SPT_Diffuse,    
          SceneCameraState( GFX->getViewport(), frust, GFX->getWorldMatrix(), GFX->getProjectionMatrix() ),    
          renderPass,    
          false    
       );
to
SceneRenderState state    
       (    
          gClientSceneGraph,    
          SPT_Diffuse,    
          SceneCameraState( GFX->getViewport(), frust, MatrixF::Identity, GFX->getProjectionMatrix() ),    
          renderPass,    
          false    
       );

Nice ... I was using GuiObjectView and got quite frustrated with the object rotating off screen ... so I put a GuiMouseEventCtrl on top of it so players can't rotate the object or interact with it. Was an interim solution until I could come up with an alternative later ... guess I don't have to anymore.

Thanks ... now I can remove that and let players rotate their model. 8-}

Much obliged ... 8-}

Same thing i had to do to fix it, but i don't think it was ever added to the repo.

"i don't think it was ever added to the repo."

setting mCameraRot and mCameraPos value to 0 was an temporary fix.may be that is why, it was never merged into repo.
if u dig into github pull requests, u will see discussion on that matter.

i have fixed this issue(+some other major improvements on gui side).
i will try to test it with development branch and will push it.

dont know what wrong is happening on developemnt branch!!!!!!!!!!!!!!
i have cheched it out.then tried to build.
got 18 errors into "gfx\gl\gfxglwindowtarget.cpp".
"
Error 22 error C2664: 'GFXGLPreserveInteger::GFXGLPreserveInteger(GLenum,GLint,GFXGLPreserveInteger::BindFn)' :
cannot convert parameter 3 from 'void (__stdcall *)(GLenum,GLuint)' to 'GFXGLPreserveInteger::BindFn' d:\torque3d git\engine\source\gfx\gl\gfxglwindowtarget.cpp 62
"
************************************************

for now,here is quick copy paste:
void GuiObjectView::fitToShape()
{
   if ( !mModel )
      return;

   Box3F bounds;
  
   if ( mModel )
      mModel->computeBounds( 0, bounds );
   mOrbitPos = bounds.getCenter();

  
   F32 len_x = bounds.len_x();
   F32 len_z = bounds.len_z();
   F32 shapeRadius = mSqrt( len_x*len_x + len_z*len_z ) / 2;
   F32 viewRadius = 0.45f * getMin( getExtent().x, getExtent().y );

  
   mOrbitDist = ( shapeRadius / viewRadius ) * mSaveWorldToScreenScale.y;
  
}

at end of
"void GuiObjectView::setObjectModel( const String& modelName)"
and
"bool GuiObjectView::onWake()"
add:
fitToShape();


mCameraRot.set( 0.0f, 0.0f, 3.9f );  
  mCameraPos.set( 0.0f, 1.75f, 1.25f );

SceneRenderState state    
       (    
          gClientSceneGraph,    
          SPT_Diffuse,    
          SceneCameraState( GFX->getViewport(), frust, MatrixF::Identity, GFX->getProjectionMatrix() ),    
          renderPass,    
          false    
       );
