Detailed Description

An implementation of a manipulable clipping plane for visualization of model interiors and cross sections.

It also provides functions for visualizing the clipping plane itself.

Member Function Documentation

vec3 center ( ) const

the center of the clipping plane.

float cross_section_width ( ) const

inline

returns the thickness of the cross section.

The thickness is defined relative to the scene bounding box. Default value is 0.01.

ClippingPlane * instance ( )

static

returns the instance of the clipping plane. The entire program will have only one clipping plane.

vec3 normal ( ) const

the normal direction of the clipping plane.

sets up whether a primitive should be completely discarded if one of its vertices is clipped.

Parameters

program	The shader program.
plane_clipping_discard	Controls clipping plane behavior. true: completely discard a primitive if one of its vertices is clipped by this clipping plane. false: standard plane clipping

void set_program ( ShaderProgram * program ) const

sets up the shader program for rendering.

Parameters

program The shader program.
