Inheritance diagram for Track::DrawableMesh:
Public Types | |
| RM_WIREFRAME | |
| each face is drawn as a loop of lines | |
| RM_SOLID | |
| Complete textured faces. | |
| enum | RenderMode { RM_WIREFRAME, RM_SOLID } |
| Method for rendering. More... | |
Public Member Functions | |
| DrawableMesh (std::istream &source, RenderMode render_mode=RM_SOLID) | |
| construct by sucking information from an input stream. | |
| DrawableMesh (std::string filename, RenderMode render_mode=RM_SOLID) | |
| Construct from the contents of a file. | |
| DrawableMesh (const MeshFaces &mesh, RenderMode render_mode=RM_SOLID) | |
| construct from a MeshFaces obect | |
| DrawableMesh (RenderMode render_mode=RM_SOLID) | |
| construct an empty mesh | |
| virtual | ~DrawableMesh () |
| virtual void | draw () const |
| Render the mesh using OpenGL commands. | |
| virtual void | make_cache () const |
| Load the mesh into OpenGL to speed up first draw. | |
| void | set_render_mode (RenderMode new_render_mode) |
| Control how the mesh is displayed. | |
Protected Member Functions | |
| unsigned int * | make_list () const |
| Aquire a new display list when created without copying. | |
Static Protected Member Functions | |
| static void | delete_list (unsigned int *display_list) |
| Delete the display list when all copies deleted. | |
Protected Attributes | |
| unsigned int | display_list |
| OpenGL display list name where drawing instructions are stored. | |
| boost::shared_ptr< unsigned int > | list_handle |
| we use a shared_ptr so we can delete the display list when the last copy of the object is deleted. | |
| RenderMode | render_mode |
| Method for drawing the mesh. | |
The mesh's faces are defined using the vertex position, normal, and texture coordinates. Shaders / texturing / materials etc is left to the user.

| Track::DrawableMesh::DrawableMesh | ( | std::istream & | source, | |
| RenderMode | render_mode = RM_SOLID | |||
| ) |
construct by sucking information from an input stream.
Equivalent to Track::MeshFaces::MeshFaces(std::istream &). Reads data from the stream to initlalise the mesh, and leaves the stream read position at the end of the DrawableMesh.
| source | The stream to use to initalise the mesh. | |
| render_mode | The method of displaying the mesh. You can set this later with set_render_mode() instead. |
Definition at line 26 of file DrawableMesh.cpp.
| Track::DrawableMesh::DrawableMesh | ( | std::string | filename, | |
| RenderMode | render_mode = RM_SOLID | |||
| ) |
Construct from the contents of a file.
Reads data from the file specified to initlalise the mesh.
| filename | The filename of the file to use. | |
| render_mode | The method of displaying the mesh. You can set this later with set_render_mode() instead. |
Definition at line 40 of file DrawableMesh.cpp.
| Track::DrawableMesh::DrawableMesh | ( | const MeshFaces & | mesh, | |
| RenderMode | render_mode = RM_SOLID | |||
| ) |
construct from a MeshFaces obect
| mesh | MeshFaces to use. | |
| render_mode | The method of displaying the mesh. You can set this later with set_render_mode() instead. |
Definition at line 33 of file DrawableMesh.cpp.
| Track::DrawableMesh::DrawableMesh | ( | RenderMode | render_mode = RM_SOLID |
) |
construct an empty mesh
| render_mode | The method of displaying the mesh. You can set this later with set_render_mode() instead. |
Definition at line 47 of file DrawableMesh.cpp.
| Track::DrawableMesh::~DrawableMesh | ( | ) | [virtual] |
Definition at line 53 of file DrawableMesh.cpp.
| void Track::DrawableMesh::delete_list | ( | unsigned int * | display_list | ) | [static, protected] |
Delete the display list when all copies deleted.
It is static to meet requirements of boost::shared_ptr.
| display_list | the display list number to remove. Should be that of the object that is being deleted. |
Definition at line 160 of file DrawableMesh.cpp.
| void Track::DrawableMesh::draw | ( | ) | const [virtual] |
Render the mesh using OpenGL commands.
Expects the texture and matrices to be set up already. Must be called outside of a glBegin/glEnd pair. Finishes with no change to the matrices, outside of a glBegin/glEnd pair.
Implements Track::Drawable.
Definition at line 57 of file DrawableMesh.cpp.
| void Track::DrawableMesh::make_cache | ( | ) | const [virtual] |
Load the mesh into OpenGL to speed up first draw.
Requires the OpenGL context that will be used to draw active. Only needs to be called once, before draw is called. Calling it after draw is called or multiple times has no additional effect.
Definition at line 67 of file DrawableMesh.cpp.
| unsigned int * Track::DrawableMesh::make_list | ( | ) | const [protected] |
Aquire a new display list when created without copying.
It generates the display from the MeshFaces data.
Definition at line 75 of file DrawableMesh.cpp.
| void Track::DrawableMesh::set_render_mode | ( | RenderMode | new_render_mode | ) |
Control how the mesh is displayed.
If the new RenderMode is the same as the previous, there is no effect. Otherwise this will unset the cache created by a previous call to draw() or make_cache(), if any. The deafult RenderMode is RM_SOLID.
| new_render_mode | The method used by draw() or make_cache(). |
Definition at line 165 of file DrawableMesh.cpp.
unsigned int Track::DrawableMesh::display_list [mutable, protected] |
OpenGL display list name where drawing instructions are stored.
Definition at line 90 of file DrawableMesh.h.
boost::shared_ptr<unsigned int> Track::DrawableMesh::list_handle [mutable, protected] |
we use a shared_ptr so we can delete the display list when the last copy of the object is deleted.
Definition at line 95 of file DrawableMesh.h.
