I chose a cloudy morning to take the photos. I wanted to take the photos quickly, and since the area around the tree was uneven, I did not use a tripod. Manual mode with shutter speed 1/80, f-stop 9 and ISO 200, so all the images have the same exposure. I used a Nikon D5100, very basic DSLR camera. The last step is creating small branches with leaves and placing them on main branches.Retopologizing the entire 3d model to a lower polygon model and unwrap it for baking the textures.Brought the Low low detail model into ZBrush for cleanup and creating the top main branches.Generated High and Low detail model from the photogrammetry software.I took photos of the tree trunk area from the ground to roughly above my head.“Creating Natural 3D Environments with Alex Alvarez” on Gnomon’s YouTube channel.īoth of them show case studies of how the used photogrammetry in their projects.īefore I dive into the process, here it is in short : What inspired me are two videos I watched. And my final goal is to present it online in Sketchfab, so keeping it relatively low poly is necessary. So this personal project is mainly focused on the process of transforming the photogrammetry result to a useful 3d model. Although the incredible model generated from photogrammetry software, its high polygon count, and errors or missing details won’t allow you to use it straight away. I always have a great interest in photogrammetry. I’d like to share some of my experience on photogrammetry modeling from my recent personal project. Big thanks, Ronen, for the opportunity to write here! I’m Xiao Fei Li, Senior 3d Artist currently working for Playdemic in the UK. This is his process using photos, Zbrush, and great 3d modeling skills. Keeping tabs on how to use photogrammetry in Architectural Visualization, I revisited The GrowFX Tree at the Archipelago House article by Radek Ignaciuk where he used GrowFX and replaced the Truck with one based on photos he took and thought about how others might do it? Looking at the gaming industry, I found an amazing looking tree done by Xiao Fei Li, a Senior 3d Artist in a gaming company.
