Hi again (if anyone check posts this far down in the list ;)
& Thanx for replying!...
--Well... the idea of frustum clipping has crossed my mind before, but after giving up on trying to understand it (extracting frustum planes from the transform matrix, something that complex cant be fast ;) ...i also whant 3x3 matrices and not 4x4 homo ones =) I will defenitely go for bounding boxes + clipping every tria in the object with SH.
--if i stick to a 2D field I will trye to get quadmap working..(need to debug some examples in C first) which will tell me what objects are close to the FOV code edges & might need clipping & the ones which are totally inside & will need no clipping. (full oactree will be in... .... v10 perhapps :) (or never).
--My question about the optimal render pipeline will come some time later ;)
--about method suting HW: Well imagine you have a realy realy FAST (blittschnell! =) blitter... and a "dsp" (named GPU) at 25MIPS and 4Kb internal sram.. thats the jaguar in a nuttshell... The blitter can draw gouroudshaded lines scanline wise. all the rest the GPU needs to calculate.
Thats about it... I just dont know what "method" it is realy suited for ...none realy ;)
Blitting stuff (codesegments & partial poly info back & forth with the blitter is the only way for bigger programs).
Well.. you also have another processor... a DSP (modulus adds, mirror (for FFTs), extra long MACs) that has 8Kb of sram... BUT a 16bit bus :(( (what is it with atari and 16bit busses? :) ..well atleast it isnt 8bit ;)
Thanx for answering some of my questions!
cul8er!

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
