Abstract class defining the interface for objects that buffer geometry for later rendering.
Definition GeometryBuffer.h:44
Intermediate OpenGLES implementation of a RenderTarget.
Definition RendererModules/OpenGLES/RenderTarget.h:43
static const double d_yfov_tan
tangent of the y FOV half-angle; used to calculate viewing distance.
Definition RendererModules/OpenGLES/RenderTarget.h:67
void draw(const RenderQueue &queue)
Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents.
bool d_matrixValid
true if saved matrix is up to date
Definition RendererModules/OpenGLES/RenderTarget.h:71
void draw(const GeometryBuffer &buffer)
Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents.
OpenGLESRenderer & d_owner
OpenGLESRenderer that created this object.

void setArea(const Rectf &area)
Set the area for this RenderTarget. The exact action this function will take depends upon what the co...
double d_viewDistance
tracks viewing distance (this is set up at the same time as d_matrix)
Definition RendererModules/OpenGLES/RenderTarget.h:73
OpenGLESRenderTarget(OpenGLESRenderer &owner)
Constructor.
const Rectf & getArea() const
Return the area defined for this RenderTarget.
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 ...
void activate()
Activate the render target and put it in a state ready to be drawn to.
void deactivate()
Deactivate the render target after having completed rendering.
Rectf d_area
holds defined area for the RenderTarget

virtual void updateMatrix() const
helper that initialises the cached matrix
Renderer class to interface with OpenGLES.
Definition RendererModules/OpenGLES/Renderer.h:67
Class that represents a queue of GeometryBuffer objects to be rendered.
