const GLchar* g_vertex_shader is the source code of the vertex.

RATIONAL_NUMBER g_zoom controls the zoom.

vector g_p_vertex_set_2 is an array containing.

vector g_p_vertex_set_1 is an array containingД¬ontaining vertex indices to build triangles from.

Transformation matrix of the second 3D object.

MATRIX4 g_object_2_rotation_matrixcorresponds to the.

Transformation matrix of the first 3D object.

MATRIX4 g_object_1_rotation_matrix corresponds to the.

PolygonMesh g_polygon_mesh_2 is the polygon mesh of the second.

PolygonMesh g_polygon_mesh_1 is the polygon mesh of the first.

Shader g_display_shader is the shader program used to.

GLsizei g_window_height keeps track of the window height.

GLsizei g_window_width keeps track of the window width.Listing 3 shows the global variables that are used: gVirtualXRay includes graphics elements such as PolygonMesh.Listing 2 shows the name spaces that can be selected: 53 #include 'gVirtualXRay/OpenGLUtilities.h' 54 55 #include 'gVirtualXRay/PolygonMesh.h' // Handle 3D triangle meshes 56 #include 'gVirtualXRay/Shader.h' // Handle GLSL programs 57 58 #include 'buildCube.h' // Create the triangle mesh of a cube

gVirtualXRay/OpenGLUtilities.h defines some utility functionsД®.g.

gVirtualXRay/Units.h defines units such as metre, kilometre,.

gVirtualXRay/Types.h defines new types, e.g.

cstdlib defines return status ( EXIT_SUCCESS and.

sstream is used to generate error messages.

Be careful here as Apple installed it somewhere else.
