Detailed Description

Direct3D11TextureTarget - allows rendering to Direct3D 10 textures.

Member Function Documentation

void CEGUI::Direct3D11TextureTarget::activate ( )
virtual

Activate the render target and put it in a state ready to be drawn to.

Note
You MUST call this before doing any rendering - if you do not call this, in the unlikely event that your application actually works, it will likely stop working in some future version.

Reimplemented from CEGUI::Direct3D11RenderTarget.

void CEGUI::Direct3D11TextureTarget::deactivate ( )
virtual

Deactivate the render target after having completed rendering.

Note
You MUST call this after you finish rendering to the target - if you do not call this, in the unlikely event that your application actually works, it will likely stop working in some future version.

Reimplemented from CEGUI::Direct3D11RenderTarget.

void CEGUI::Direct3D11TextureTarget::declareRenderSize ( const Size sz)
virtual

Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations.

Note
The main purpose of this is to allow for the implemenatation to resize the underlying texture so that it can hold the imagery that will be drawn.
Parameters
szSize object describing the largest area that will be rendererd in the next batch of rendering operations.
Exceptions
InvalidRequestExceptionMay be thrown if the TextureTarget would not be able to handle the operations rendering content of the given size.

Implements CEGUI::TextureTarget.

Texture& CEGUI::Direct3D11TextureTarget::getTexture ( ) const
virtual

Return a pointer to the CEGUI::Texture that the TextureTarget is using.

Returns
Texture object that the TextureTarget uses when rendering imagery.

Implements CEGUI::TextureTarget.

bool CEGUI::Direct3D11TextureTarget::isImageryCache ( ) const
virtual

Return whether the RenderTarget is an implementation that caches actual rendered imagery.

Typically it is expected that texture based RenderTargets would return
true in response to this call.  Other types of RenderTarget, like
view port based targets, will more likely return false.
Returns

Implements CEGUI::RenderTarget.

bool CEGUI::Direct3D11TextureTarget::isRenderingInverted ( ) const
virtual

Return whether rendering done on the target texture is inverted in relation to regular textures.

This is intended to be used when generating geometry for rendering the
TextureTarget onto another surface.
Returns
  • true if the texture content should be considered as inverted vertically in comparison with other regular textures.
  • false if the texture content has the same orientation as regular textures.
