Detailed Description

Create a geometry for a "cylinder." The cylinder is aligned to the Z axis where the base starts at z=0 and height runs along the positive Z direction. This is not a strict cylinder because the base radius can be different from the top radius (a top_radius == 0, results in a cone). The number of slices corresponds to the number of divisions around the circumference, and the number stacks corresponds to the number of divisions along the height dimension (normally 1). A boolean in the constructor argument is used to specify whether or not end caps are to be created (without them this object is a tube).

{\bf Example:}

\begin{verbatim} vector<sglStatelet*> state; state.push_back(new sglLighting(true)); state.push_back(new sglTransparency(true)); state.push_back(new sglCullMode(sglCullMode::eOFF)); sglMaterial *material = new sglMaterial(); material->setAmbient(0.0f, 0.5f, 1.0f); material->setDiffuse(0.0f, 0.5f, 1.0f); material->setAlpha(0.5f); state.push_back(material);

sglCylinder *cylinder = new sglCylinder(20, 1, 4.0f, 2.0f, 0.5f, true); cylinder->setState(0, state, NULL);

sglGeode *geode = new sglGeode; geode->addGeometry(cylinder); \end{verbatim}

Constructor & Destructor Documentation

sglCylinder::sglCylinder ( unsigned int num_slices, unsigned int num_stacks, float height = 1.0f, float base_radius = 1.0f, float top_radius = 1.0f, bool end_caps_flag = true )

Constructor. Parameters: num_slices   Number of divisions in the tesselation around the circumference; must be greater than 2. num_stacks   Number of divisions in the tesselation along the length; must be greater than 0 height   Length of the cylinder; must be greater than 0. base_radius   Radius at the base; must be greater than 0. top_radius   Radius at the top; must be non-negative. end_caps_flag   If true, the end caps will be created.

sglCylinder::~sglCylinder ( ) [virtual]

virtual destructor.
