WaveFront OBJ converted from LightWave taking forever to render on iPhone -

-

i'm working on project need render 3d human body on ios device. 3d object built in adobe lightwave , 7.4mb. opened in blender , exported obj/mtl pair 5.5mb , 4kb, respectively. using jeff lamarche's wavefront loader (linked below) starting point figure out opengl es , check out performance , whatnot, stuck object in there (in place of obj/mtl pair he'd been using) , ran in simulator. of course, crash on startup, decided performselectorinbackground it. half hour later, it's still loading.

i'm guessing file way detailed draw kind of performance expectation on device 600mhz processor. there way lower quality these files easily? or, if performance issues have arisen particular loader, enlighten me?

thanks, will

will,

i don't know if can solve problem, may able point in right direction. did project client loading 3d model exported blender using sio2 3d engine.

anyway, @ time, had trouble 3d engine taking long time load model. found reducing number of polygons important - if high quality model, need so.

blender has function - polygon reduce or that. blender should report how many polygons , surfaces in use, if it's more than, say, 20,000, you're in performance issues.
