Member Function Documentation

ComputeCostSigned()

void SDFUnary2::ComputeCostSigned ( const Vector2 & p )

virtual

Compute the number of reccursive calls to Signed().

Author

Reimplemented from SDFNode2.

Reimplemented in SDFFrame2, SDFRotate2, SDFScale2, SDFTranslate2, and SDFUniformScale2.

GetCostShader()

QString SDFUnary2::GetCostShader ( PrimitiveManager & primitives, std::list< QString > & dependency, bool & valid_glsl ) const

virtual

Compute the GLSL code to compute the cost of a call to sdf.

Signed()

double SDFUnary2::Signed ( const Vector2 & p ) const

virtual

Compute the signed distance.

Parameters

p

Point.

Reimplemented from SDFNode2.
