Detailed Description

A functor to limit rendering.

Member Function Documentation

getFloatingOrigin()

Eagle::tvector3 Wizt::RegionOfInterest::getFloatingOrigin ( const RefPtr< AnemoneCreatorBase > &  AC )

static

Get the numerical value of the floating origin for this specific AnemoneCreator.

If the translation shift is positive then the origin is negative. Subtract this origin from all absolute coordinate values to get values in the shifted coordinate system. Such subtractions must be done on the CPU in double precision to allow the resulting relative values to fit into the single precision of the GPU. Each Anemone may have its own Origin.

setupRegionOfInterest()

RenderNamespace::glsl Wizt::RegionOfInterest::setupRegionOfInterest ( VRenderContext &  Context, const FloatingAnemone &  FA  )

virtual

Defines a GLSL function that has to be called before each vertex is emitted, i.e.

either in the vertex shader or before EmitVertex() in the geometry shader.

#define HAVE_vish_clipRegionOfInterest 1
void    vish_clipRegionOfInterest(vec3 Vertex, vec3 Origin);
 
#define HAVE_vish_validateRegionOfInterest 1
bool    vish_validateRegionOfInterest(vec3 Vertex, vec3 Origin);

Note that the name of the shader variable that contains the origin is given by the member FA.getFloatingOrigin();
