Re: Custom Rendering
Hi,
Yes you can access vertex positions, textures, etc.
If you want it only for cube rendering you can use already defined following functions:
Code:
struct Mshb
{
Mshb& createPlane (Int x=2,Int y=2,UInt flag=0 ); // create plane , 'flag'=VTX_FLAG
Mshb& createFast (Box &box ); // create box (fast)
Mshb& create (Box &box ,UInt flag=0 ,Int resolution=-1 ); // create box , 'flag'=VTX_FLAG
Mshb& create (Ball &ball ,UInt flag=0 ,Int resolution=-1 ); // create ball in cube mode and uv mapping, 'flag'=VTX_FLAG
Mshb& create2 (Ball &ball ,UInt flag=0 ,Int resolution=-1,Int resolution2=-1); // create ball in spherical mode and uv mapping, 'flag'=VTX_FLAG
Mshb& createHalf (Ball &ball ,UInt flag=0 ,Int resolution=-1 ); // create ball's upper half , 'flag'=VTX_FLAG
Mshb& create (Capsule &capsule ,UInt flag=0 ,Int resolution=-1,Int resolution2=-1); // create capsule , 'flag'=VTX_FLAG
Mshb& createFast (Tube &tube , Int resolution=-1 ); // create tube (fast)
Mshb& create (Tube &tube ,UInt flag=0 ,Int resolution=-1 ); // create tube , 'flag'=VTX_FLAG
Mshb& create (Cone &cone ,UInt flag=0 ,Int resolution=-1 ); // create cone , 'flag'=VTX_FLAG
Mshb& create (Torus &torus ,UInt flag=0 ,Int resolution=-1,Int resolution2=-1); // create torus , 'flag'=VTX_FLAG
...
};
these functions generate meshes out of geometrical shapes,
if you wish however to manually setup each vertex and triangle, please use something like this:
Code:
Mshb mshb; // mesh base
// use this function to create a mesh - Mshb& create(Int vtxs ,Int edges,Int tris,Int quads,UInt flag=0 ); // create, 'vtxs'=number of vertexes, 'edges'=number of edges, 'tris'=number of triangles, 'quads'=number of quads, 'flag'=MSHB_FLAG
mshb.create(100, 0, 100, 0, VTX_TX0); // create a mesh with 100 vertexes, 100 triangles and include VertexTextures (VTX_TX0) creation (VTX_POS-vertex positions and TRI_IND-triangle indexes are created automatically)
// now you can access freely - mshb.vtx.pos, mshb.vtx.tx0, mshb.tri.ind
// for example:
mshb.vtx.pos[0].set(0,0,0); // set position of 0th vertex
mshb.vtx.tx0[0].set(0,0); // set UV mapping of 0th vertex
mshb.tri.ind[0].set(0,1,2); // set indexes of 0th triangle
