Member Function Documentation

begin()

bool Wizt::TransformOperator::Functor::begin ( VRenderContext &  Context ) const

virtual

Start the transformation operation, given some rendering context.

The function may return false to indicate that the requested transformation is not possible. The calling object will then abort rendering.

getShaderFunctions()

string Wizt::TransformOperator::Functor::getShaderFunctions

(

VRenderContext &

Context

)

const

               Get a definition of three shader functions of the following signature:

vec4    vish_transform_vertex_WorldToEye(in RelativeVertex theVertex);
vec4    vish_transform_vertex_EyeToScreen(vec4 theVertex_in_EyeSpace);
vec3    vish_transform_normal_WorldToEye(vec3 TheNormal);

as based on the myShaderFunctions() virtual function, plus it includes the getDefaultShaderFunctions() code and the getConvenienceShaderFunctions() code.

myShaderFunctions()

string Wizt::TransformOperator::Functor::myShaderFunctions ( VRenderContext &  Context ) const

virtual

               Must define three shader functions of the following signature:

vec4    vish_transform_vertex_WorldToEye(vec4 theVertex, vec3 TranslationVector);
vec4    vish_transform_vertex_EyeToScreen(vec4 theVertex_in_EyeSpace);
vec3    vish_transform_normal_WorldToEye(vec3 TheNormal);

These function may call the shader functions as predefined in getDefaultShaderFunctions(VRenderContext&Context);
