Problem with proyection matrix when videobacground has not drawed

October 9, 2014 - 3:23am #1

Hello, i have a pair of issues that i try to resolve with that question:

https://developer.vuforia.com/forum/qcar-api/projection-matrix-and-modelviewmatrix-indentity-issue

And i find that the answer to the second question (use my own projection matrix make objects wider) is because i create my own projection matrix and then the render calls drawvideobackground and i dont know why all is wider.

My problem now is that im trying to handle a pick on object using colorpicking way, but for that i need to render the objects withouth render video background, and when i try this the objects are narrowed than the size with videobackground.

It seems that when video background was drawed, the projection matrix of vuforia changes...  And i dont know why.

Ahy help please!!
