The way I have my code setup for detecting terrain collision is based from the player character model, it checks in real time the distance between the detected vertices of the terrain mesh Y (vertical axis), if the character is below that it places the character above it, it has no performance impact and it isn't noticeable visually as it does. How would I do fast collision detection with it, on the magnitude O(1) like a heightmap if possible? Also if you can advice about having a large terrain th I'm thinking if using a mesh instead of a heightmap for terrain because I can add detail where needed like mountains and add overarching ridges. For this purpose, the described mesh of every individual object serves as its respective collision geometry. Unless those gears are perfect (pro tip: they aren't), you are going to have something called backlash. Please consider supporting this small channel and helping it grow!
