Function Documentation

background_window()

bool igl::opengl::glfw::background_window

(

GLFWwindow *&

window

)

Create a background window with a valid core profile opengl context set to current.

After you're finished with this window you may call glfwDestroyWindow(window)

After you're finished with glfw you should call glfwTerminate()

Parameters

[out]

window

pointer to glfw window

Returns

true iff success

map_texture() [1/2]

template<typename DerivedV , typename DerivedF , typename DerivedU >

bool igl::opengl::glfw::map_texture	(	const Eigen::MatrixBase< DerivedV > &	_V,
		const Eigen::MatrixBase< DerivedF > &	_F,
		const Eigen::MatrixBase< DerivedU > &	_U,
		const unsigned char *	in_data,
		const int	w,
		const int	h,
		const int	nc,
		std::vector< unsigned char > &	out_data,
		int &	out_w,
		int &	out_h,
		int &	out_nc
	)

Given a mesh (V,F) in [0,1]² and new positions (U) and a texture image (in_data), render a new image (out_data) of the same size.

Parameters

[in]	V	#V by 2 list of undeformed mesh vertex positions ∈ [0,1]²
[in]	F	#F by 3 list of mesh triangle indices into V
[in]	U	#U by 2 list of deformed vertex positions ∈ [0,1]²
[in]	in_data	w*h*nc array of color values, channels, then columns, then rows (e.g., what stbi_image returns and expects)
[in]	w	width
[in]	h	height
[in]	nc	number of channels
[out]	out_data	h*w*nc list of output colors in same order as input
[out]	out_w	width of output image
[out]	out_h	height of output image
[out]	out_nc	number of channels of output image

Precondition

Seems like w,h should be equal.

map_texture() [2/2]

template<typename DerivedV , typename DerivedF , typename DerivedU >

bool igl::opengl::glfw::map_texture	(	const Eigen::MatrixBase< DerivedV > &	V,
		const Eigen::MatrixBase< DerivedF > &	F,
		const Eigen::MatrixBase< DerivedU > &	U,
		const unsigned char *	in_data,
		const int	w,
		const int	h,
		const int	nc,
		std::vector< unsigned char > &	out_data
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
