		float	x,
		float	y,
		float	z,
		float	x_scale,
		float	y_scale,
		float	z_scale,
		bool	fill = `true`
	)		const

Draws this Spore in a matrix.

The drawing plane (M) has normal vector <x,y,z> = <0,0,1> in 3-space, i.e., it is parallel to the xy-plane. The parameter z specifies the distance of the drawing plane from the origin (0,0,1).

The parameters x and y specify the location of M->elts[0][0] in the spore coordinate system. Increasing indices of m correspond to increasing values of x and y scaled by x_scale and y_scale, respectively.

Formally, the center of the (i,j)th element of M in spore coordinates will be

      x_0 = x + x_scale*(i + 0.5); 
      y_0 = y + y_scale*(j + 0.5); 
      z_0 = z + z_scale*0.5;

The position of (x_0,y_0,z_0) in m is given by

      i = floor((x_0 - x) / x_scale + 0.5);
      j = floor((y_0 - y) / y_scale + 0.5);

Parameters:

M	Matrix to draw spore in.
x	Position of the first m column index in the spore coordinate system.
y	Position of the first m row index in the spore coordinate system.
z	Position of m in the spore coordinate system.
x_scale	Number of spore coordinate system units per column in m.
y_scale	Number of spore coordinate system units per row in m.
z_scale	Number of spore coordinate system units per matrix.
fill	Set to true if the spore is to be filled; false otherwise.

Returns:: True if any of the structures intersect with something other than one of its children.

		float	z_scale,
		bool	fill = `true`
	)		const `[virtual]`

Draws this Spore in a matrix block.

The drawing planes (M_blk) have normal vectors <x,y,z> = <0,0,1> in 3-space, i.e., parallel to the xy-plane. The parameter z specifies the distance of the drawing plane from the origin (0,0,1).

The parameters x, y, and z specify the location of mb->elts[0][0][0] in the spore coordinate system. Increasing indices of mb correspond to increasing values of x, y, and z scaled by x_scale, y_scale and z_scale, respectively.

Formally, the center of the (i,j,k)th element of M_blk in spore coordinates will be

      x_0 = x + x_scale*(i + 0.5); 
      y_0 = y + y_scale*(j + 0.5); 
      z_0 = z + z_scale*(k + 0.5);

The position of (x_0,y_0,z_0) in M_blk is given by

      i = floor((x_0 - x) / x_scale + 0.5);
      j = floor((y_0 - y) / y_scale + 0.5);
      k = floor((z_0 - z) / z_scale + 0.5);

Parameters:

M_blk	Matrix block to draw spore in.
x	Position of the first mb column index in the spore coordinate system.
y	Position of the first mb row index in the spore coordinate system.
z	Position of the first mb matrix in the spore coordinate system.
x_scale	Number of spore coordinate system units per column in mb.
y_scale	Number of spore coordinate system units per row in mb.

Calculates an intersection point between a line and this Spore, if it exists.

Parameters:

quad	GLUquadric to use for drawing.

p2_in	End point of the line to intersect.

Returns:: If the n^th intersection point is found, its parametric distance along the line from p1_in to p2_in is returned in the range [0,1]. Otherwise a value < 0 is returned.

void Spore::draw_in_zeroed_matrix_f	(	jwsc::Matrix_f *	M,

		float	y,
		float	z,
		float	x_scale,
		float	y_scale,
		float	z_scale,
		bool	fill = `true`
	)		const `[protected]`

Draws this Spore in a zeroed matrix.

The drawing plane (M) has normal vector <x,y,z> = <0,0,1> in 3-space, i.e., it is parallel to the xy-plane. The parameter z specifies the distance of the drawing plane from the origin (0,0,1).

The parameters x and y specify the location of M->elts[0][0] in the spore coordinate system. Increasing indices of m correspond to increasing values of x and y scaled by x_scale and y_scale, respectively.

Formally, the center of the (i,j)th element of m in spore coordinates will be

      x_0 = x + x_scale*(i + 0.5); 
      y_0 = y + y_scale*(j + 0.5); 
      z_0 = z + z_scale*0.5;

The position of (x_0,y_0,z_0) in m is given by

      i = floor((x_0 - x) / x_scale + 0.5);
      j = floor((y_0 - y) / y_scale + 0.5);

Parameters:

M	Matrix to draw spore in.
x	Position of the first m column index in the spore coordinate system.
y	Position of the first m row index in the spore coordinate system.
z	Position of m in the spore coordinate system.
x_scale	Number of spore coordinate system units per column in m.
y_scale	Number of spore coordinate system units per row in m.
z_scale	Number of spore coordinate system units per matrix.
fill	Set to true if the spore is to be filled; false otherwise.

Warning:: In order to do proper filling of the spore, the matrix M must be empty (zero) prior to calling this function.
