2.5 d
« on: September 12, 2008, 01:50:08 am »
Do you think 2.5 d would work in software mode?  I'm just curious.  Assuming I could get a camera to look the same from Blender to Jpct, would it run an applet of 500 X 300 or so with a full background and a couple 3d characters?  I could try hardware also, and maybe going full 3d would be better anyway.

If the 2D uses parallel projection, the perspectives wouldn't match, because jPCT does perspective projection. Some people tried to compensate this by using a very small fov and a huge distance to the object, but i've never seen anything but screen shots (which looked reasonable well) from this approach.

I think I'll try full 3d first, then.

I think it's a 3d character in a 2d or isometric world...at least that is what i was referring to in my answer.

I know what you mean by parallel projection now.  In Blender it's called orthographic.  I was thinking of using it for an adventure game with perspective projection.  So you think it would work with a full screen overlay in software render on a 500X300 window?

In theory yes, but as said: Parallel and perspective projection don't match very well. Cyberkilla did that in the past (http://www.jpct.net/forum2/index.php/topic,697.0.html), but the screen shots seem to be gone.
