Remove 3D effect

Jan 25, 2011 at 7:01 AM


I have created sample application using the SLARToolkit. As per the marker moment it adjust the image. I want to disable the 3D effect so that image will remain flat on the screen. Can anyone help me to disable the 3D effect?

You will have to look into the Matrix3D struct and reset all the elements for the 3rd dimension before you apply the perspective transformation. Since it's a matrix you can't extract the scale and rotation, because they are multiplied, but You can easily extract the translation from the matrix (Offset properties):

Or you can use the coordinates of the Square property that is provided in a DetectionResult. See the SLARToolkit sample about how it's used there to draw a red rectangle around the marker.
