Irrlicht Engine

If you have a wrapper, surely you can multiply the Z value there? The internal Z value can be the layer times 20.

The fastest way would be to transform the object's bounding box, and then use that, either as a box or as a sphere.

It is a matrix multiply per node, and not needed in many applications, so it should be calculated on-demand rather than automatically. Good idea otherwise.

You can include more than one image in one post...

You still used a local variable.

Your returned pointer is invalid. The object disappears when the function returns.

You only scale in the Z direction. You may want to scale in XZ or all three.

Or a hint of Eva.

To use nearest interpolation in irr, disable anisotropic, trilinear, and bilinear in the material.

Typedef a void pointer, or use a struct.

Install git-svn, or whatever it's called, then you can use git commands.

Bleed is a known issue with texture atlases, usually hit when using mipmaps, but also possible due to floating point inaccuracies with mipmaps disabled. In short: if your hw supports texture arrays, use them instead. If you need texture atlases, in your 2d case you should disable mipmaps and set the...

Your picture had no hills. With rugged terrain, you should use a shader.

If your ground is flat, the easiest way is to place a quad at 0.01 y, textured with that circle.

The guidelines for the last models that had non-unified shaders should apply decently to common integrated units today.
