flatten()

std::vector<T> armarx::viz::grid::flatten

(

const std::vector< std::vector< T >> &

vector

)

Flattens a 2D vector of nested vectors to a 1D vector.

Here is the call graph for this function:

makeGrid2DColors()

std::vector<std::vector<viz::data::Color> > armarx::viz::grid::makeGrid2DColors	(	const std::vector< std::vector< Eigen::Vector3f >> &	vertices,
		std::function< viz::Color(size_t x, size_t y, const Eigen::Vector3f &p)>	colorFunc
	)

Build colors of a 2D grid.

Parameters

vertices	The vertices.
colorFunc	A function determining the color of each vertex.

Returns

The colors.

makeGrid2DVertices()

makeGrid2DFaces()

std::vector< viz::data::Face > makeGrid2DFaces	(	size_t	num_x,
		size_t	num_y
	)

Builds faces of a 2D grid.

The built indexes refer to flattened arrays of vertices and colors, such as produced by flatten() applied to the result of makeGrid2DVertices().

Parameters

num_x	The number of vertices in x-axis.
num_y	The number of vertices in y-axis.

Returns

The faces.

Definition at line 108 of file Mesh.cpp.

makeGrid2DVertices()

std::vector< std::vector< Eigen::Vector3f > > makeGrid2DVertices	(	Eigen::Vector2f	extents,
		Eigen::Vector2i	numPoints,
		float	height = 0
	)

Builds vertices of a regular 2D grid in the xy-plane.

If the result is indexed as result[i][j], the i index represents the x-axis, the j index represents the y-axis.

Parameters

extents	The full extents per axis.
numPoints	The number of points per axis.
height	The height (z-value).

Returns

The vertices.
