Functions
void	draw (const HMesh::Manifold &m, bool per_vertex_norms=true)
	Draw a HMesh Manifold. Inefficient and should be compiled into display list.
void	draw (const Geometry::IndexedFaceSet &geometry)
	Draw an indexed face set (just a triangle list) with normals computed on the fly.
void	draw (const Geometry::TriMesh &tm, bool per_vertex_norms=true)
	Draw a triangles mesh. Inefficient function that should be compiled into a display list.
void	load_textures (Geometry::TriMesh &tm)
	Load textures if available.
template<class T >
void	draw_wireframe_oldfashioned (const T &m, bool per_vertex_norms, const CGLA::Vec3f &line_color)
	Draw an object of type T as wireframe. In practice T = Manifold or TriMesh.
template void	draw_wireframe_oldfashioned< HMesh::Manifold > (const HMesh::Manifold &m, bool per_vertex_norms, const Vec3f &line_color)

Detailed Description

The namespace for things related to (real time) rendering.

This namespace is for functionality that requires OpenGL. For instance a virtual trackball class and a more complex view controller. There are functions for drawing meshes and other geometric entities from other parts of OpenGL. There is also SOIL, the image loading library for OpenGL, by Jonathan Dummer.

Function Documentation

GLuint GLGraphics::create_glsl_shader	(	GLuint	stype,
		const std::string &	src
	)

Create a shader of type specified by the first argument from a source string given as second argument. Return shader handle. If there is a problem, the infolog is printed and 0 is returned.

GLuint GLGraphics::create_glsl_shader	(	GLuint	stype,
		const std::string &	path,
		const std::string &	file
	)

Create a shader of type specified as first argument from the file indicated by the supplied path and file name (second and third arguments) and return a shader handle. This function is only a convenience function wrapping read_glsl_source and create_glsl_shader

template<class BoxType >

void GLGraphics::draw	(	const Geometry::BoundingINode< BoxType > &	node,
		int	level,
		int	max_level
	)

Draw the tree. The first argument is the level counter, the second argument is the level at which to stop drawing.

const std::string GLGraphics::read_glsl_source	(	const std::string &	path,
		const std::string &	file
	)

The two arguments are concatenated to form the name with full path of a text file. This file is read and returned as a string.
