Perspective correction controlled through OSC #35

Open ibiltari opened 4 years ago

ibiltari commented 4 years ago

Hi, for an upcoming project (https://github.com/stagesoft) we need this feature and we are planning to implement it on xjadeo, perhaps it could be interesting to include it in the main branch like the other art related features?

x42 commented 4 years ago

xjadeo does not have any perspective control to begin with, so it cannot be exposed via OSC.

You could probably implement this for the openGL variants in opengl_draw (in display_gl_common.h), changing the coordinates of the GL_QUADS.

Yes thanks!, i'm trying to implement it just like that, modifying the glTexCoord2f of the plane.

I have it working and exposed trough OSC, now im working in the correct texture projection mapping so it can be successfully used to correct perspective from a physical projector.

My main question was about if you think it could be and interesting addition and i should try to integrate the code with IFDEF's like the other "art" features so i could generate a pull request when ready and tested. It would be nice for us because we are planning on integrating xjadeo in another open source project and we need this feature.

That does sound great! PR is definitely welcome.
