Mountain Wireframe
Hey guys,
been tasked with putting a mesh over some footage of a mountain. Imagine this composition – https://unsplash.com/photos/aerial-photography-of-mountain-range-covered-with-snow-under-white-and-blue-sky-at-daytime-9wg5jCEPBsw
But it’s going to be a panning shot – subtle movement. The idea is to show the grand scale of the mountain – there’ll be some stats alongside it showing height etc.
I know this will involve some sort of cam tracking, but was just wondering how you guys would approach such a problem in c4d? Both creating the mesh based on the live action shapes and animating it on and off.
Thanks.

Hi Robert,
You could put the image in a background and then make a rough model of the part of the mountain that the mesh you want to create will interact with. You can simulate part of the mountain either by modeling it or by using a Landscape Object and playing with the properties until you get something similar. Then you will hide that and let the mesh appear as if it is interacting with the image. I attach a screen recording to explain how this works, I hope this is helpful to you.

Thanks so much Kouraib! That’s really helpful. I probably should’ve made this clearer, but I’ll be dealing with video footage here. So the scene will be very similar to the image, but it’ll have a slight pan to it. I’m guessing I could just make the landscape as you mentioned, then 3D camera track within cinema 4d?

You’re welcome, Robert! If that’s the case, the same method applies, but using a camera movement path. If you have the option to make the movement only a zoom-in or zoom-out motion, that would be better. However, if you must move the camera along a path parallel to the image, it’s preferable to make the movement subtle and keep the camera at a distance to maintain the realism of the mesh’s interaction with the mountain image. Please let us know if it works for you so that everyone here can benefit from it.

Thanks Kouraib. So the movement will be in the footage. The real life camera is going to move from right to left very subtly. So I think it’ll just be a case of using C4D’s inbuilt cam tracking tools to match that movement, which then in a perfect world would create a Redshift camera that would match my mesh to the footage. Fingers crossed!

You are welcome! You’ll need tracking tools if you have a real video and want to match the position or movement of a model you created to the movement of objects in the video. I think in your case it’s different; you have a still image, and only the objects you created will move in your scene, so there’s no need for tracking. Just try to make the camera movement not too large on the axis parallel to the image to maintain the realism of the interaction between the mesh and the image of the mountain. I hope this makes sense.
