The shape is seen decomposed into triangles. These are used to calculate reflection of light from the surface of the object. The triangles are formed from chords of the curves in the shape. The deviation coefficient gives the highest value of the angle with which a chord can deviate from a tangent to a curve. If this limit is reached, a new triangle is begun.

The deviation coefficient give the highest value of the angle with which a chord can deviate from a tangent to a curve. If this limit is reached, a new triangle is begun. To find the hidden lines, hidden line display mode entails recalculation of the view at each different projector perspective.

const Handle< Prs3d_DatumAspect >& Prs3d_Drawer::DatumAspect ( )

Returns settings for the appearance of datums. These settings can be edited. The default values for the three axes are: Color: Quantity_NOC_PEACHPUFF Type of line: Aspect_TOL_SOLID Width: 1.0.

Standard_Real Prs3d_Drawer::DeviationAngle ( ) const

inline

Returns the value for deviation angle.

Standard_Real Prs3d_Drawer::DeviationCoefficient ( ) const

inline

Returns the deviation coefficient. Drawings of curves or patches are made with respect to a maximal chordal deviation. A Deviation coefficient is used in the shading display mode. The shape is seen decomposed into triangles. These are used to calculate reflection of light from the surface of the object. The triangles are formed from chords of the curves in the shape. The deviation coefficient gives the highest value of the angle with which a chord can deviate from a tangent to a curve. If this limit is reached, a new triangle is begun. This deviation is absolute and is set through the method: SetMaximalChordialDeviation. The default value is 0.001. In drawing shapes, however, you are allowed to ask for a relative deviation. This deviation will be: SizeOfObject * DeviationCoefficient.
