void GL_Polygon_Renderer::project ( Polygon &  p )

static

Projects this polygon onto the image plane using the current OpenGL transformation.

Parameters

p	The polygon to project The polygon points are transformed and projected onto the view plane by the current modelview and projection matrix on the GL stack.

The origin of the view plane coordinate system is in the lower left corner and its extents are defined by the current GL viewport size.

void GL_Polygon_Renderer::project ( Polygon &  p, const Matrix &  M, double  width, double  height  )

static

Parameters

p	The polygon to project The polygon points are transformed and projected onto the view plane by the current modelview and projection matrix on the GL stack.

The origin of the view plane coordinate system is in the lower left corner and its extents are defined by the current GL viewport size.

void GL_Polygon_Renderer::solid_occlude_render ( const Polygon &  p )

static

Renders this polygon in the Z buffer.

Does not render into the color buffer, only in the depth buffer.

Parameters

p	The polygon to render

void GL_Polygon_Renderer::solid_render ( const Polygon &  p )

static

Renders this polygon as a solid using OpenGL.

Parameters

p	The polygon to render Does not set color or material effects.

void GL_Polygon_Renderer::solid_render_with_bases ( const Polygon &  p, unsigned int  base1 = 0, unsigned int  base2 = 0  )

static

Renders this polygon as a solid using OpenGL.

void GL_Polygon_Renderer::wire_occlude_render ( const Polygon &  p )

static

Renders this polygon into the depth buffer using OpenGL, excluding the contour.

Parameters

p	The polygon to render Does not render into the color buffer, only the depth buffer.

After calling this method, call wire_render() to render the polygon with hidden lines occluded.

void GL_Polygon_Renderer::wire_render ( const Polygon &  p )

static

Renders this polygon as a wireframe using OpenGL.

Does not set color or material effects.

Parameters

p	The polygon to render

unsigned int GL_Polygon_Renderer::wire_render_with_sequential_ids ( const Polygon &  p, unsigned int  start_id = 1  )

static

Render each edge of this polygon with a different color. The first edge will be rendered using the input id as a color, the following edges will be rendered with an id sequentially increasing. Returns the id (color) used to render the last edge of the polygon.

Render each edge of this polygon with a different color. The first edge will be rendered using the input id as a color, the following edges will be rendered with an id sequentially increasing

Parameters

p	The polygon to render
start_id	The color for the first edge of the polygon

Returns

The last id used

unsigned int GL_Polygon_Renderer::wire_render_with_sequential_ids_16bits ( const Polygon &  p, unsigned int  start_id = 1  )

static

Render each edge of this polygon with a different color. The first edge will be rendered using the input id as a color, the following edges will be rendered with an id sequentially increasing

Parameters

p	The polygon to render
start_id	The color for the first edge of the polygon

Returns

The last id used
