      Those all must be much easier, too much code I cant understand immediately, there must be an abstraction level to handle all 3d Envirionment, such as object loading or working with coordinates. People who has weak maths, such as me, cant use those featuers.

      Just look on G3DFormat file - wicked for me!

      @Yan, you are welcome contributing :)

      @MoKaLux, here is the code:

      excellent, looking forward to using it. I have never coded in 3D before and would be delighted to do it in gideros. Thank you very much hgy29.

      With the help of reactphysics3d engine, yes: it has raycasting functions that could be used to check for 'click'.

      I decided to try to render shadows. It took a few minors changes in Gideros rendering code, mainly the ability to render depth result to a rendertarget. Here is the result:

      Now with textures:
      Nice isn't it ?

      impressive indeed.
      is the gravity intentionally low or it is slower due to computational power?

      Gravite is set to 9.8, but the units are what you want anyhow. However the floor reaction isn’t good, because it’s mass is the same as the cubes, which isn’t realistic. However for the demo I wanted the cubes to bounce all over the place.
      Throughout the video the FPS is a solid 60, with roughly 3% cpu usage. But this is on my pc, I don’t have figures for mobile yet.

      Nice! o:) If I hadn't my freaking long project, I'd try to make Helix Jump prototype out of curiosity for 3d

      Waiting for the mobile figures here :)

      Indeed it is, seems really nice, thanks for the resarch and implementation. I am sure when it will finish a small demo of this implementation will bring lots of new faces to our community.

      if you can shoot those barrels then we could probably shoot some weird aliens from outta space too! :)

      It opens a lot of possibilities to gideros: sport simulation (bowling, golf, ping pong, etc), 3D shooters, space game (doigt fight, mining, platform docking), 3D racing, aircraft simulation,...
