We’ve written a TC 3d file manager - http://www.geocities.com/udodenko/tc.zip
It’s Delphi5 based, sources are open. Based on GLCL OpenGL Delphian class library.
It appears to be too slow (50 fps on Riva 128 , ~14 fps on Software) for graphics of this kind(without textures).
I have some questions about optimization(for software mode):
a)Is such framerate Ok for 56 bars and lots of lines or it can be faster?
b)I render file bars as 56 separate DLs. Outside of DLs are Push/Pop/Translatef/Rotatef and glMaterialfv.
Will it be faster if I put them inside the DL?
c) Will it be faster if I put this bars into 4 DLs? I’ll have to recompile them pretty often because of hottrack highlight.
d)I draw letters using lines. Are letters using textures faster in software?
e)Are such things as VertexArray(or smth like that) faster than DLs in software?
f)Are glMaterialfv’s eating perfomance if I call them few times for each bar?
Any optimization hints will be appreciated.
Also it’ll be good if someone will benchmark TC on GeForce.
We made TC able to read visualizations from DLLs(visualization is an interface). We already have working C++ visualization(that writes on DC). If somebody wants to write own file manager visualization tell me - I’ll write normal documentation and upload it. Our filemanager core does all OpenGL initialization, sends mouse/keyboard messages, loads dir contents, sorts and filters files, does file operations, dragdrop,updates folder contents and something else. So everything needed to implement visualization is displaying folder contents and buttons and handle mouseclicks.
