Hi !
I want to add a kind of shadows to an application, if you have ever used RayDream for example you know what I am talking about.
I have one or more objects and around these objects I have three grid planes (one on each axis) and I want to display the contour (or shadow) of the objects on the grid planes, but with the same size as the original objects so the light source should have parallel rays…
This if for a 3D modeler, presenting the contour of the objects on the grid planes makes it easier to see how the objects are oriented to each other.
Does any one have an idea on how to do this or have a pointer to information about this subject ?
As the grid planes are planar quads and they are always axis aligned it should be possible to optimize this a bit, i think… maybe…
