Detailed Description

Generic class for creating geometric meshes.

This class has to be derived for creating the mesh. In your derived class constructor, call the functions setEdgeNumber() and setVertexNumber() to set the topology of your mesh. Then create a function fillMesh() where you will define all the vertices and all the triangles of the mesh.

Member Function Documentation

void GeometricMesh::addTriangle (  int  I0, int  I1, int  I2, bool  CCW = true, bool  detectborder = false )  [protected]

This function adds 3 vertices in the buffer, making a triangle. Parameters: I0  The index of one corner vertex. I1  The index of one corner vertex. I2  The index of one corner vertex. CCW  If FALSE the 3 vertices are inserted in that order: I0, I2, I1. This changes the direction of the face normal and the side where the texture will appear. detectborder  If TRUE, the function tries to detect of a border of the texture is crossing this triangle. If yes the U coordinates are re-ajusted.

void GeometricMesh::addVertex (  Real  radius, Real  Vx, Real  Vy, Real  Vz )  [protected]

This function adds a vertex in the Meshbuffer. The vertex is defined by its Position + Normal and UV coordinates. Spherical UV mapping is always applied. Parameters: radius  The radius. You can set it to 1, and use real XYZ positions, or set it to a real value and use XYZ value in the rang [0..1]. Vx  The X position of the vertex. Vy  The Y position of the vertex. Vz  The Z position of the vertex (vertical axis).

void GeometricMesh::addVertexUV (  Real  radius, Real  Vx, Real  Vy, Real  Vz, Real  U = AUTO, Real  V = AUTO )  [protected]

This function adds a vertex in the Meshbuffer. The vertex is defined by its Position + Normal and UV coordinates. Parameters: radius  The radius. You can set it to 1, and use real XYZ positions, or set it to a real value and use XYZ value in the rang [0..1]. Vx  The X position of the vertex. Vy  The Y position of the vertex. Vz  The Z position of the vertex (vertical axis). U  The U coordinate (optional). If undefined, spherical UV mapping is automaticaly applied. V  The V coordinate (optional). If undefined, spherical UV mapping is automaticaly applied. See also: addVertex

void GeometricMesh::createMesh (  String  MeshName  )

This function generates a Manual Ogre Mesh. Parameters: MeshName  The name that will be given to the new created mesh.

void GeometricMesh::initializeMesh (  String  MeshName, int  vertexNB, int  triangleNB )  [protected]

This function initialize all the structures and buffers, for creating a manual mesh. Parameters: MeshName  The name that will be given to the mesh. vertexNB  The number of vertices needed for the mesh. triangleNB  The number of triangles of the mesh.
