Abstract	:	Conventional wisdom tells us that dot product based bump mapping requiresspecialized hardware, but we show that this form of per-pixel lighting can be performedinteractively on today's consumer class hardware with nothing more than core OpenGLfunctionality. The key to the approach described here is a multipass approximation of thevector dot product combined with use of the alpha buffer as a scalar accumulation buffer.This technique replaces complex per-fragment operations with multiple rendering passes,which generally demands a high fill rate or small window for interactive use, but it isamenable to a number of pass-collapsing optimizations that help mitigate these concerns.....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
