rFactor2: Early Development Physics Blog Brabham BT44B 1975. Now for something a little different! Michael Borda, the Virtual Vehicle Engineer at Image Space Incorporated has introduced a physics development blog on ISI’s official website.
Michael begins his blog by taking you through the process of optimizing vehicle physics in rFactor 2. The ultimate aim of this first instalment covers tackling migrating physics models from rFactor to rFactor2. Future spreadsheet releases will provide more detailed explanations during the process. Michael also thinks this is a great way to obtain feedback from the community, as well as the community using this blog, to learn more about programming physics of car and tyre models.
The example car that Michael has chosen for this first blog is the Brabham BT44B F1 car from 1975. This car will be a Steam exclusive development release. For those of you that like to get their virtual hands dirty, you can head over to Michael’s blog to learn more about basic car and tyre physics from an expert!
