Re: [PD] making gem units be pixels

[Thomas Grill]

Hi,

gr~~~

for that i normally use abstractions that do the coordinate transformation after the gemhead without changing the camera (see attachment: vis-test uses the other files). But, since for a project i'm working on a more general solution for simple UI widgets in gem including mouse and keyboard interaction, that brings me to the question if anyone has already done something like that. One would assume yes....

hi,

after fuzzing around with 3d to pix conversions for the xth time, I thought it should also be possible to set the camera to a point that just allows to have all units in pixels with the 0/0 in the top left corner. the only way to get this working was to set the camera to a negative z position and flip the upvector. the problem with that is, that all images will be vertically flipped, too. so I wonder whether there could be a general gemwin switch to flip + and - on the y axis? and again, it would be extremely cool to have a possibility to read out the curent size of the gemwin. marius.<camera_pixel_view.pd>_________________________________________ ______ UNSUBSCRIBE and account-management -> http://lists.puredata.info/ listinfo/pd-list
