Collaboration diagram for VoxelCube:
Public Methods | |
| void | draw (bool bTranslateToCenter) |
| Draw our voxels as cubes, with glutSolidCube. More... | |
| double | getMinimumFarPlane (Vertex COP, Vertex lookatPoint) const |
| We don't want our far plane to clip the back of our VoxelCube. This method gives you the minimum far plane that won't clip. | |
| bool | isTransparent (int x, int y, int z) const |
| Returns whether a particular voxel has been carved (and is therefore transparent). More... | |
| bool | isTransparent (const VoxelPos &p) const |
| Returns whether a particular voxel has been carved (and is therefore transparent). | |
| int | getVoxelsPerSide () const |
| If you cube this number, you get the total number of voxels in the VoxelCube. | |
| void | fillItemBufferArray (Viewpoint &image) |
| Draws the cube to an item buffer, and converts that into an array of integers. The caller must allocate the array, and its size must be width x height. | |
| std::vector< Vertex > | calculateVoxelCorners (int x, int y, int z) const |
| Get the 8 corners of a given voxel. More... | |
| Rect< double > | getBoundingRect (std::vector< Vertex > &vertices, const double modelMatrix[16], const double projMatrix[16], const int viewport[4]) const |
| Gets the projected bounding-rectangle for a set of vertices. | |
| unsigned int | PosToIdentifier (int x, int y, int z) const |
| Gets the item-buffer identifier for a given voxel. | |
| unsigned int | PosToIndex (int x, int y, int z) const |
| We have a one-d array of voxels. This maps a 3d coordinate to a position in our voxel array. | |
| Vertex | getCenter () const |
| Gets the position of the center of the voxel cube. | |
| double | getVoxelSize () const |
| Returns the size (width or height, it's all symmetrical) of each voxel. | |
| unsigned int | GetEdgeID (unsigned int nX, unsigned int nY, unsigned int nZ, unsigned int nEdgeNo) |
| Helper method for marching cubes. More... | |
| void | setFinalColor (SurfaceVoxelList::iterator i, RgbByte &color) |
| Adds a voxel to our final list of colored voxels, and assigns it a color. More... | |
| void | setVoxelsPerSide (int vps) |
| Set the number of voxels on each side, meaning that the total # voxels would be vps^3. More... | |
| void | exposeSurroundingVoxels (SurfaceVoxelList::iterator i) |
| When a voxel disappears, some of its neighbors may be made visible. This exposes any solid, previously unexposed, neighboring voxels. More... | |
| void | VoxelCube::setTransparent (SurfaceVoxelList::iterator i) |
| Set a specified voxel cube to be transparent. Note that you MUST also remove the corresponding voxel from the surface voxel list, after calling this method. | |
| void | setCenter (Vertex new_center) |
| void | setVoxelSize (double voxel_size) |
| This sets the width of every voxel to voxel_size. | |
| void | makeMesh (float isoLevel, QEM::ProgMesh &mesh) |
| Make a polygonal mesh out of our voxel grid. More... | |
Public Attributes | |
| SurfaceVoxelList | svl |
In addition to drawing the opaque voxels, this class can return an item buffer for an arbitrary perspective.

Get the 8 corners of a given voxel.
Definition at line 30 of file VoxelCube.cpp. |
|
|
Draw our voxels as cubes, with glutSolidCube. If our list of colored voxels has been filled in, then we draw that; otherwise, we draw our list of uncolored voxels. Definition at line 622 of file VoxelCube.cpp. |
|
|
When a voxel disappears, some of its neighbors may be made visible. This exposes any solid, previously unexposed, neighboring voxels. Voxels that surround the given voxel, that are not already marked transparent (in "solids") will be added to the surface voxel list (svl).

Helper method for marching cubes. This code was adapted from code by Raghavendra Chandrashekara, available at... http://astronomy.swin.edu.au/~pbourke/modelling/polygonise/rchandra/ Definition at line 371 of file VoxelCube.cpp. Referenced by makeMesh(). |

Returns whether a particular voxel has been carved (and is therefore transparent). This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Adds a voxel to our final list of colored voxels, and assigns it a color. This method can only be called once for each surface voxel (calling it twice for a voxel would mean that there'd be two identically-positioned-voxels in the svl -- a bad idea.
