Collision Detection of 2 Hidden 3D Objects?
I plan to have several prerendered characters shown up as billboards, and at the same time, simple rigged 3D characters are hidden and are placed in the same coordinates of the billboards.
The interactions of the hidden 3D characters will be checked constantly, and the contents of the billboards updated accordingly.
Does my plan above seem to be workable???
Thanks! If this implementation is finished, the results are games with low hardware requirements but high-quality graphics.
The problems of the implementation are many shaders needed to be worked out, and the storage of the frames of the prerendered 3D characters, etc.
Anyone has any ideas???
sounds fantastic.
rigs with hidden universe, puppeted items etc are great !
FWIW I can't see the slightest performance problem or issue.
for such a happily normal scene as you describe I wouldn't even bother or think about shaders. just use a suitable ordinary shader from the many offered by Unity.
having offscreen items for physics calculations is quite normal. You just use one line of code to set the position of your "puppets" in the scene!
regarding the 2D images, use 2DToolkit. it is almost impossible to do 2.5D work without it and it will save you a year of work, it's great
Beyond this it is not possible to fully understand what you're doing unless you make a screenshot to give the idea.
But everything you mention sounds completely "SOP" - enjoy!
