i have 2 questions to Projection mapping:
- if i make an animation in some 3D Program and want to project it on an 3D Surface in real how do i place the camera in the 3D Program proper?
Because if i render it out of the 3D Program the camera might have another angle compared to the projector in VVVV.
Is there any trick or something?
Basic example i have a cube i want to project on.
That cube should explode.
That exploding animation is made in a 3D Program, how do i render out proper, that it fits with real cube?
- More or less resulting from the 1. question:
If now some particles from the exploding cube are moving over an edge of the Cube in real, the projection is distorted at some corners again.
Is there also any trick?
I know describing visual stuff is very difficult but maybe somebody knows what i mean.
try it with animated mesh
Ill take a look at them.
Is there someone here how can help me with my projects - for pay obviously.
sure thing write on skype
You have to take the photos in te same situation of proyectors… then you place a proyector in 3d program and make the 3d models from the picture you taked… then you have to put another cam from the people point of view and render all the stuff from that cámera… you probably have a distorted video (the people usually don’t see the show from the same point of view that proyectors have), so you have to use something like homografy to reoriente the video and to fit the structure…
I personally use the plug-in DX Texture (RR)that I found here, and use it with Resolume Arena to send the renderer inside resolume… so you can VJing with a lot of stuff including your VVVV Patchs…
… hope I could help you…
PD: Sorry about my english… I’m not so good…
Here is where I Found this fantastic plugin…
this is a very usefull tool to share DirectX textures to OpenGL…
thanks to Elio for his work…
