Rendertexture memory pointer to opencv
Hi, I was wondering if it is possible to get a memory pointer to rendertexture, so I could use it and do image processing in opencv
Unity has a function GetNativeTextureID for accessing textures from native code.
But it's address on the graphics card memory right? How I could access it from OpenCV? any ideas? I would like to write an application in which I could make some affine transformations on image for projection mapping so i could drag skew etc parts of the image based on a grid
If you don't have to get tour data into opencv per se, you could take the approach that Paul Bourke uses to render stereo pairs. (http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/stereographics/Unitystereo/) Then you can easilly manipulate the geometry that is textured with your rendertexture, before it is rerendered in the 2nd camera.
