… and about #1 if you can export in .x the you are all setup, although I have never tried wit 3dMax. Eventually you may be able to export as .obj then import in Blender then export as .x (look for the proper plugin… )
I don t understand #2 and I don t know the app mentioned in #3
I downloaded the projection mapping_2projectorssetup.zip from the website and i understand how it works but the question is if i want to project on the 3d shape (.x file) how can i input the video ? what i mean is if i want to make a mapping of this building in real life how can i use vvvv? how can i make the projector in the scene project my 3d contents ?
I don t completely understand your question, but whenever you ll have a 3D model of your real object, you would just send the xfile to a shader where you could add light effects or apply textures, etc.
It s worth remembering that often, since a facade can be just flat, you ll find it easier to make a 2D creation and control the distortion with homography. Small details can be fixed in situ.
Useless to say that the mesh/3D approach is the one giving you mo re possibilities. Remember to add a laser distance measurement on the material list ;)
i am trying to replace the hfgpappmodell.X in the root folder of the projectionmapping_2projection with another mesh i created in 3dsmax but i cant get any visualization of it in the rendering windows…
Say i want to use vvvv to project on the building how can i make the projectors project a video ? i dont know if im clear but i need to know how this software can be used to make a projection mapping ? ?
ok find yourself a box with sharp edges (not a pillow I mean…) place the projector so that its beam can cover the box, possibly place the box so that a vertical edge is facing the projector, so to say try to cover three faces with the the projector s beam. Now open the patch and fiddle with the 2 Transform 3D nodes, so that you can recreate the real situation in the “monitor” renderer (of course the other renderer goes fullscreen to the projector).
Remember also to input the proper values in the Projector node, details on your projector’s manual.
EDIT: just to make it clear, your goal is to fit the projection of the virtual box onto the real box
