3D component palette for lazarus as in Delphi (DeleD?)
lazarus / 39-Graphics

Delphi 10 (DX) offers some 3D visual components
(http://docwiki.embarcadero.com/RADStudio/Seattle/en/FireMonkey_3D):
- TViewPort3d (something like lazarus TOpenGLControl?);
- 3D scene components: TCamera, Tlight, TDummy and TProxyObject;
- a set of 3D Shapes components (TPlane, TDisk, TCube, TMesh,
TSphere...);
- a set of 3D Layers components;
- a set of Materials components.

There is something similar in Lazarus?
I know there is GLScene as a separated package, I was just wondering
if there is the chance to introduce these 3D components in lazarus
existing component palette.
DeleD has something similar.

Yes. Install GLScene

GLScene
Exactly. It registers its components to the existing component
palette, just as you wished.
Unfortunately GLScene seems to support only Windows. Somebody should
fork it and make a cross-platform version.

Firemonkey is a different thing altogether, but afaik newer Delphi's
even have directwrite components in the VCL.

I assume it is possible, but somebody simply has to find or create
direct* headers, maintain them, and work on the components.

Here is few links for pascalized DirectX headers:

One more link to add to the list Cyrax provided:

https://github.com/CMCHTPC/DelphiDX12

Despite the name, it is fully FPC compatible, and definitely the most
up-to-date DirectX header I am aware of.

I would also agree that GLScene might be what you're looking for. (Fun
fact: FireMonkey (the Delphi component you referenced) is actually
itself based on a FORK of GLScene, which was called DXScene (and was
really just a stripped down version of GLScene that used DirectX 9
instead of OpenGL as a rendering backend.) To be quite honest, as
well, I would say that the current revision of FireMonkey has far from
caught up to where the current revision of GLScene is today, in terms
of features/e.t.c.

You might also want to try out the Castle Game Engine, which is
extremely robust (and much more modern "internally" than GLScene...
far less slow GLBegin/GLEnd stuff), but is also perhaps a little less
easy to get started with due to the lower number of "visual"
components it provides.
