Yes the 3dfx Voodoo4 and 5 cards can do bump mapping in Glide 32 Bit which can only be used with a ebta driver from AmigaMerlin.
the Voodoo5 cards [not Voodoo4] also allow Motion Blur in Glide mode + Super Sampled Rotated Grid FSAA x2 and x4 as where the mighty Voodoo5 6000 Protoypes also allow Super Sampled Rotated Grid FSAA x8 mode
here the FSAA tab of the Voodoo5 6000 I once had in the past:

Here pics of the card it's self, it's sheer size is 32.5CM incl the extended support bracket, the black brick is the Voodoo Volts a 60 watt PSU, the card does not need that , since it has been upgraded with an Internal Power Hookup which only uses 55 watts:
Ah well I sold this card 4 years ago for about 1700 euro's and yeah someday I will reobtain one for more Descent 3 fun
