Drawing a cyliner

[Caspian]

I'm trying to create a cylinder scene node... but I don't see any sort of "addCylinderSceneNode" method -- is there any way to add a cylinder without having to create my own custom scene node?

I looked into custom scene nodes, and I really don't want to dive into specifying all the triangles myself (especially since my cylinder will be stretching and rotating). If there's an easier way, I'd be very happy .

Thanks!

Nope there isn't one. I'm glad to hear that you looked before posting. :)

Yes. You can use an IMeshSceneNode. You can either make the cylinder in a modelling program and then load the mesh like the example programs do for more complicated meshes, or you can create your own mesh buffer, stuff that into a mesh and set the mesh for the scene node.

Then the best thing to do is to find or make a model of a cylinder and use that.

Scale and rotation can be done independently from the mesh. If you are going to scale and rotate the cylinder often, you would make a single cylinder primitive that has fixed dimensions [say a diameter of 1 and a length of 1]. If you wanted to make the diameter grow, you would apply a scale factor to the scene node that holds the mesh. So to make the cylinder 2x as tall, you set the scale to core::vector3df(1, 2, 1).

Thanks, vitek!

I created a cylinder using Blender and imported it (it was easier than I thought!)

I had thought that for something as simple as a cylinder I wouldn't need a "custom" scene node... but, oh well

Thanks for your help .
