Detailed Description
This interface describes the API for the general mesh factory.iGeneralFactoryState inherits from iGeneralMeshState. All methods from iGeneralMeshState as set on the factory will serve as defaults for mesh objects that are created from this factory AFTER the default value is set. So changing such a value on the factory will have no effect on meshes already created. The material wrapper is an exception to this rule. Setting that on the factory will have an effect immediatelly on all mesh objects created from that factory except for those mesh objects that have their own material set.
Main creators of instances implementing this interface:
- Genmesh mesh object plugin (crystalspace.mesh.object.genmesh)
- iMeshObjectType::NewFactory()

| virtual iGeneralMeshSubMesh* iGeneralFactoryState::AddSubMesh | ( | iRenderBuffer * | indices, | |
| iMaterialWrapper * | material, | |||
| const char * | name, | |||
| uint | mixmode = (uint)~0 | |||
| ) | [pure virtual] |
Add a submesh to this object.
A submesh is a subset of the mesh triangles rendered with a certain material. When a mesh has one or more submeshes, only submeshes are drawn and not original geometry. That means submeshes should cover all original triangles to avoid holes in the mesh.
- Remarks:
- SubMeshes added to an instance of a genmesh will override the submeshes from the factory (i.e. the submeshes of the factory will be completely ignored as soon as the instance has submeshes).
- Parameters:
-
indices Render buffer holding the geometry for the submesh in usual render buffer formatting, ie for triangles three vertices for every triangle. material Material to assign to the submesh. name (Optional) Name to identify the submesh. mixmode (Optional) Mixmode to override the mesh's mixmode.
- Returns:
- The added submesh, if successful.
- Remarks:
- This will change the indices of other submeshes.
| virtual void iGeneralFactoryState::AddTriangle | ( | const csTriangle & | tri | ) | [pure virtual] |
Add a triangle.
This is one way to fill the triangle table. The other way is to use SetTriangleCount() and then fill the table manually.
| virtual void iGeneralFactoryState::AddVertex | ( | const csVector3 & | v, | |
| const csVector2 & | uv, | |||
| const csVector3 & | normal, | |||
| const csColor4 & | color | |||
| ) | [pure virtual] |
Add a vertex.
This is one way to fill the vertex and other tables. The other way is to use SetVertexCount() and then fill the tables manually.
| virtual void iGeneralFactoryState::CalculateNormals | ( | bool | compress = true |
) | [pure virtual] |
Automatically calculate normals based on the current mesh.
/param compress if true (default) then calculate the normals based on compressed vertices.
| virtual void iGeneralFactoryState::ClearSubMeshes | ( | ) | [pure virtual] |
Remove all submeshes added to this object.
| virtual void iGeneralFactoryState::Compress | ( | ) | [pure virtual] |
Compress the vertex table.
This should be called after setting up the geometry.
| virtual void iGeneralFactoryState::DeleteSubMesh | ( | iGeneralMeshSubMesh * | mesh | ) | [pure virtual] |
Delete a submesh.
| virtual void iGeneralFactoryState::DisableAutoNormals | ( | ) | [pure virtual] |
Disable auto-generated normals.
This does not have an effect on the current normals, but only changes the return value of IsAutoNormals(). However, this affects saving of genmesh factories, as all vertex normals will be written out explicitly.
| virtual iGeneralMeshSubMesh* iGeneralFactoryState::FindSubMesh | ( | const char * | name | ) | const [pure virtual] |
Find the index of a submesh.
The index can be used with DeleteSubMesh() and the GetSubMesh...() methods. Returns 0 if the submesh was not found.
| virtual void iGeneralFactoryState::GenerateBox | ( | const csBox3 & | box | ) | [pure virtual] |
Automatically generate a box.
This will set the number of vertices to eight and generate vertices, texels, normals, and triangles. The vertex colors are set to black.
| virtual void iGeneralFactoryState::GenerateSphere | ( | const csEllipsoid & | ellips, | |
| int | rim_vertices, | |||
| bool | cyl_mapping = false, |
|||
| bool | toponly = false, |
|||
| bool | reversed = false | |||
| ) | [pure virtual] |
Automatically generate a sphere.
This will set the apropriate number of vertices and generate vertices, texels, normals, and triangles. The vertex colors are set to black.
- Parameters:
-
ellips Properties of the ellipsoid to generate. rim_vertices Number of vertices on a rim. cyl_mapping if true then use cylindrical texture mapping. toponly if true then only generate the top half of the sphere. reversed if true then generate the sphere so it is visible from the inside.
| virtual iGenMeshAnimationControlFactory* iGeneralFactoryState::GetAnimationControlFactory | ( | ) | const [pure virtual] |
Get the current animation control factory for this factory.
| virtual const csColor& iGeneralFactoryState::GetColor | ( | ) | const [pure virtual] |
Get the color.
| virtual csColor4* iGeneralFactoryState::GetColors | ( | ) | [pure virtual] |
Get the array of colors.
It is legal to modify the colors in this array (but don't forget to call Invalidate()). The number of colors in this array will be equal to the number of vertices set. Note that modifying the colors will not do a lot if manual colors is not enabled (SetManualColors).
| virtual csVector3* iGeneralFactoryState::GetNormals | ( | ) | [pure virtual] |
Get the array of normals.
It is legal to modify the normals in this array (but don't forget to call Invalidate()). The number of normals in this array will be equal to the number of vertices set. Note that modifying the normals is only useful when manual colors are not enabled and lighting is enabled because the normals are used for lighting.
| virtual iGeneralMeshSubMesh* iGeneralFactoryState::GetSubMesh | ( | size_t | index | ) | const [pure virtual] |
Get a specific submesh.
| virtual size_t iGeneralFactoryState::GetSubMeshCount | ( | ) | const [pure virtual] |
Get the number of submeshes.
| virtual csVector2* iGeneralFactoryState::GetTexels | ( | ) | [pure virtual] |
Get the array of texels.
It is legal to modify the texels in this array (but don't forget to call Invalidate()). The number of texels in this array will be equal to the number of vertices set.
| virtual int iGeneralFactoryState::GetTriangleCount | ( | ) | const [pure virtual] |
Get the number of triangles for this mesh.
| virtual csTriangle* iGeneralFactoryState::GetTriangles | ( | ) | [pure virtual] |
Get the array of triangles.
It is legal to modify the triangles in this array (but don't forget to call Invalidate()). The number of triangles in this array will be equal to the number of triangles set.
| virtual int iGeneralFactoryState::GetVertexCount | ( | ) | const [pure virtual] |
Get the number of vertices for this mesh.
| virtual csVector3* iGeneralFactoryState::GetVertices | ( | ) | [pure virtual] |
Get the array of vertices.
It is legal to modify the vertices in this array (but don't forget to call Invalidate()). The number of vertices in this array will be equal to the number of vertices set.
| virtual void iGeneralFactoryState::Invalidate | ( | ) | [pure virtual] |
After making a significant change to the vertices or triangles you probably want to let this object recalculate the bounding boxes and such.
This function will invalidate the internal data structures so that they are recomputed.
| virtual bool iGeneralFactoryState::IsAutoNormals | ( | ) | const [pure virtual] |
Returns whether normals were autogenerated or manual.
| virtual bool iGeneralFactoryState::IsBack2Front | ( | ) | const [pure virtual] |
Get the value of the back2front flag.
| virtual void iGeneralFactoryState::SetAnimationControlFactory | ( | iGenMeshAnimationControlFactory * | anim_ctrl | ) | [pure virtual] |

See iGenMeshAnimationControlFactory for more information.
| virtual void iGeneralFactoryState::SetBack2Front | ( | bool | b2f | ) | [pure virtual] |
Enable back to front rendering for the triangles of this genmesh.
This is useful if this factory represents a transparent genmesh or the material that is being used is itself transparent.
| virtual void iGeneralFactoryState::SetColor | ( | const csColor & | col | ) | [pure virtual] |
Set the color to use. Will be added to the lighting values.
| virtual void iGeneralFactoryState::SetTriangleCount | ( | int | n | ) | [pure virtual] |
Set the number of triangles to use for this mesh.
The easiest way to set the triangle data is to just use AddTriangle(). However, you can also call SetTriangleCount() and then call GetTriangles() to set the data that way. Note that you have to call Invalidate() after modifying the triangle data this way.
| virtual void iGeneralFactoryState::SetVertexCount | ( | int | n | ) | [pure virtual] |
Set the number of vertices to use for this mesh.
The easiest way to set the mesh data is to just use AddVertex(). However, you can also call SetVertexCount() and then call GetVertices(), GetTexels(), ... to set the data that way. Note that you have to call Invalidate() after modifying the vertex data this way.
