Making my own mesh inside of the engine

[CameroKid]

I know how to draw something on the engine:

driver->drawIndexedTriangleList(&Vertices[0], VertNumb, &indices[0], TriangleNumb);

but how can I set an IMesh pointer to what I have drawn so I can use it in the engine?

You'll have to make your own mesh buffer.

Thanks for the reply but that link doesn't help much. Is there a tutorial? This involves making a class right? I'm not sure I want a class. I want to be able to alter the verticals and triangles of the mesh whenever I want. can I do that through a class?

[Ion Dune]

Just use the public arrays inside the class I linked to instead of your own arrays, then use

Code: Select all

driver->drawMeshBuffer(...)

You will still be able to alter the vertices and triangles of the mesh. Organizing it in a class does not affect that.

There is no tutorial that specifically covers this, but tutorial 3 should get you on the right track.

I recently posted some code to create a cylinder mesh. I'm thinking you might find it useful.

Ok I think I'm a bit confused on the S3DVertex object. What is the difference from x, y ,z and nx, ny, and nz. Can someone explain what each value means? I made my own mesh and I see it fine, but when I try to use the mesh in Newton the collision doesn't match.

[Ion Dune]

x, y, and z are the position values of the vertex. nx, ny, nz is the normal vector which are used for light calculations.

Thanks for the help everything works great. Out of curiosity what are the last two coordinates in a vertex? the Tcoords

[Ion Dune]

Texture coordinates.
