Viewing Projection

[pkhoosh]

Hello,

I need to make sure that the object I have in my virtual world is perceptually plausible. For example, I need the size to be appropriate with the distance the object is from the camera.

Are there built in features from Vizard that allow this check?

Essentially, I need to know the distance the object is from the camera and the objects size. I can measure the physical projection on the screen to make check the ratio.

I have attached an image from Van Dam's lecture on Viewing.

Many thanks,

pete
