XBomb 2.2 (Default branch)
ImageXBomb is a minsweeper game with a choice of three different grids. The simplest is the hexagonal grid, next is the traditional square grid and the most complex is the triangular grid. For each of the different grid shapes there are three difficulty levels.License: GNU General Public License (GPL)Changes:
Different colors are now displayed for each of thenumbers. The left mouse button can be used inplace of the middle mouse button in mostcircumstances.Image

GLMAPGRID(3G)															     GLMAPGRID(3G)

NAME

       glMapGrid1d, glMapGrid1f, glMapGrid2d, glMapGrid2f - define a one- or two-dimensional mesh

C SPECIFICATION

       void glMapGrid1d( GLint un,
			 GLdouble u1,
			 GLdouble u2 )
       void glMapGrid1f( GLint un,
			 GLfloat u1,
			 GLfloat u2 )
       void glMapGrid2d( GLint un,
			 GLdouble u1,
			 GLdouble u2,
			 GLint vn,
			 GLdouble v1,
			 GLdouble v2 )
       void glMapGrid2f( GLint un,
			 GLfloat u1,
			 GLfloat u2,
			 GLint vn,
			 GLfloat v1,
			 GLfloat v2 )

PARAMETERS

       un  Specifies the number of partitions in the grid range interval [u1, u2].  Must be positive.

       u1, u2
	   Specify the mappings for integer grid domain values i=0 and i=un.

       vn  Specifies the number of partitions in the grid range interval [v1, v2]
	   (glMapGrid2 only).

       v1, v2
	   Specify the mappings for integer grid domain values j=0 and j=vn
	   (glMapGrid2 only).

DESCRIPTION

       glMapGrid  and  glEvalMesh  are used together to efficiently generate and evaluate a series of evenly-spaced map domain values.	glEvalMesh
       steps through the integer domain of a one- or two-dimensional grid, whose range is the domain of the evaluation maps  specified	by  glMap1
       and glMap2.

       glMapGrid1  and	glMapGrid2  specify  the  linear  grid mappings between the i (or i and j) integer grid coordinates, to the u (or u and v)
       floating-point evaluation map coordinates.  See glMap1 and glMap2 for details of how u and v coordinates are evaluated.

       glMapGrid1 specifies a single linear mapping such that integer grid coordinate 0 maps exactly to u1, and integer grid  coordinate  un  maps
       exactly to u2.  All other integer grid coordinates i are mapped so that

								    u=i(u2-u1)/un+u1

       glMapGrid2  specifies  two  such  linear  mappings.   One  maps integer grid coordinate i=0 exactly to u1, and integer grid coordinate i=un
       exactly to u2.  The other maps integer grid coordinate j=0 exactly to v1, and integer grid coordinate j=vn exactly to  v2.   Other  integer
       grid coordinates i and j are mapped such that

								    u=i(u2-u1)/un+u1

								    v=j(v2-v1)/vn+v1

       The mappings specified by glMapGrid are used identically by glEvalMesh and glEvalPoint.

ERRORS

       GL_INVALID_VALUE is generated if either un or vn is not positive.

       GL_INVALID_OPERATION is generated if glMapGrid is executed between the execution of glBegin and the corresponding execution of glEnd.
