Irrlicht Engine

Er.. maybe I spot a point in

void CSceneManager::drawAll ()

Instead of:

if (!Driver)
return;
...
// reset all transforms
video::IVideoDriver* driver = getVideoDriver();
if ( driver )
{
driver->setTransform ( video::ETS_PROJECTION, core::IdentityMatrix );
driver->setTransform ( video ...

I have the same 'complain' about Irrlicht. Let's think about it.

Knowing that the method to create a cylindrical mesh (or a plane) is ready and implemented inside the engine, it makes no sense at all not to expose it. Take a look:

1) it is faster to create programatically instead of loading a file ...

Sorry for the silly question. Here it goes.

I need to create a plan, too, but got puzzled by this topic. A billboard does not work 4 me, as it faces the camera all the time.

There is irr::core::plane3D, but I did not found a corresponding mesh-generator-thing in the API. For instance, there's no ...

I've got two problems related to scale.

(1/2)
Exporting from Blender: I thought "1 unit = 1 meter"; now, importing the mesh (a building) into Irrlicht, I have no idea about the scaling factor to apply. By applying scale = 10 it matches, more or less, "sidney.md2". I hope most models follow ...

From what I've read, the first step of math is to distort the world, so that ellipses get the shape of spheres; this makes it easier to calculate distances. BTW yes, the triangles are also distorted, but since math properties are maintained, the calculations work fine. That's the magic. The rest is ...
