Not long after he started work at Weta Workshop where he used the software to digitally draw up film set plans.
Sandy recalled the time when the miniatures department needed to measure a miniature of a large-scale model of Minis Tirith [a film set in The Lord of the Rings].
Alex suggested surveying the miniature with a laser survey tool to determine the scale of the live action set that could be built to film actors on.
She said Weta Digital became interested in using the system of surveying real sets to bring scale to Middle Earth in the digital world.
The method became the basis of the company's onset surveying system today.
"Alex was a pioneer and the driving force behind this taking place."
Alex went on to be a key surveyor for more than 40 blockbuster films including The Lord of the Rings, King Kong, X-Men: The Last Stand, I, Robot, Waterhorse: Legend of the Deep.
Alex's work was highly regarded and last year he and a colleague were contenders for an Oscar for King Kong.
"While the award didn't end up coming his way, it demonstrated Alex's hard work and determination, and above all, his innovation also prevailed."
She said Alex was a man who had presence, self-assurance, high work standards, was reliable and true to his word.
"A legend exits screen left."
She also read a message from Sir Peter Jackson who was unable to attend the funeral.
Aside for his film industry career, Alex loved being with his wife Shona and their three children Monique, Lars and Anneke.
Alex first met Shona in 1978 when he popped in for a trim in her hairdressing shop in Hataitai.
They married in 1983, and by 1990 were living in Kapiti and soon raising their three children.
He had a soft spot for Kapiti, the place he grew up in after his family immigrated from the Netherlands when he was two.
Son Lars has followed in his father's footsteps and is a senior camera technical director at Weta Digital, the same position his father held.
