First cross section from a 3D model

I've been trying constructing 3D models from few caves with the LiDAR sensors in iPhone. While I've been able to rotate these models on screen easily, I also wanted to see whether I could construct more traditional maps from these models. But it has been a big learning curve to use the 3D modelling software. Today, with the help of Olli, I finally managed to make my first cross section of a cave model in Blender.

I used the model from the main cave in Vihti's Rokokallio as the starting point. This is a vertical cross section of the main crack in this cave, the darker areas are the cave holes and the lighter areas are rock. With a complete model, I can make these cross sections along any axis or from any part of the cave.

A lot of work remains... but this is a nice start.

​TGR Tested: Dynafit Radical Boot

Dynafit's brand-new Radical Pro boot is a ski touring boot built for skiers. | Max Ritter photo. Ski touring boots are arguably the most hotly-contested niche sector of the industry, with consumers demanding all manner of things from what they put on their feet for big days in the mountains. We want them to be as light as a skimo boot. We want them to be as stiff as an alpine race boot. We want more range of motion than our ankles even allow. We want space-age materials that can be molded

It’s Truly Biblical: Man Survives Being Swallowed by Humpback Whale

A humpback whale surfaces in the pacific ocean. Michael Packard survived being swallowed by the same creature while lobster diving in Cape Cod. | Miguel Medina photo. It’s all over the news, but it still seems impossible to believe something so mind blowing. Lobster diver Michael Packard was swallowed whole by a humpback whale and survived to tell the tale. Is Packard the modern day Jonah you may ask? Our research would back that statement. Packard was 45 feet underwater, hunting for
