Hardware instancing #182

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
--- This is CRUCIAL (major improvement for high and smooth fps) ---

Remove paged-geometry close 3d models (batched geometry) which are processed on 
cpu. Each vertex of each tree in batch is multipled on cpu (pos,norm,tang,etc). 
This is the worst thing that kills fps and makes it going crazy in some places, 
never smooth when driving fast.

Now use Ogre's New instancing (HWInstancingBasic)

If paged geom 2.0 is out then check that too

OK HW instancing doesn't change much, fps is even lower but a bit smoother (no 
page load lags).
What actually kills performance and makes horrible fps jumps is Shadows !
I'm thinking of making a pre-made lightmap with tree shadows, just to have them 
not casting shadows. Looks problematic even at start (eg. different tree 
multiplier settings).

OK its only the 4k shadows. The lower have smooth fps.

Still todo: trees and grass wind animation.

OK, smoother but lower Fps with HW inst, so no big reasons to do it, and would 
require wind, and integrating into close paged-geom pages (too much trouble).
