LPDIRECT3DDEVICE9 d_device
Direct3DDevice9 interface obtained from our owner.
Definition: RendererModules/Direct3D9/RenderTarget.h:73
void draw(const GeometryBuffer &buffer)
Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents.
Direct3D9Renderer & d_owner
Direct3D9Renderer that created this object.
Definition: RendererModules/Direct3D9/RenderTarget.h:71
Direct3D9RenderTarget(Direct3D9Renderer &owner)
Constructor.
void deactivate()
Deactivate the render target after having completed rendering.
float d_viewDistance
tracks viewing distance (this is set up at the same time as d_matrix)
Definition: RendererModules/Direct3D9/RenderTarget.h:81
void setArea(const Rectf &area)
Set the area for this RenderTarget. The exact action this function will take depends upon what the co...
D3DMATRIX d_matrix
projection / view matrix cache
Definition: RendererModules/Direct3D9/RenderTarget.h:77
void unprojectPoint(const GeometryBuffer &buff, const Vector2f &p_in, Vector2f &p_out) const
Take point p_in unproject it and put the result in p_out. Resulting point is local to GeometryBuffer ...
const Rectf & getArea() const
Return the area defined for this RenderTarget.
void setupViewport(D3DVIEWPORT9 &vp) const
helper to initialise the D3DVIEWPORT9 vp for this target.
Rectf d_area
holds defined area for the RenderTarget
Definition: RendererModules/Direct3D9/RenderTarget.h:75
void activate()
Activate the render target and put it in a state ready to be drawn to.
bool d_matrixValid
true when d_matrix is valid and up to date

void draw(const RenderQueue &queue)
Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents.
void updateMatrix() const
helper that initialises the cached matrix
Renderer class to interface with Direct3D 9.
Definition: RendererModules/Direct3D9/Renderer.h:65
Abstract class defining the interface for objects that buffer geometry for later rendering.
Definition: GeometryBuffer.h:44
Class that represents a queue of GeometryBuffer objects to be rendered.
