c# - 3D project shape to 2D -

-

in demo project i'm creating objects in 3d , display axis coordinate system.

i want plot 3 different frontal views (frontal view, top view, side view) of 3d object surfaces axis spread out.

currently i'm able plot bounding boxes, want plot contour.

i have drawn it red pen bounding box, can see mean :)

enter image description here

an easy way render using same view , projection matrix, apply shadow matrix. scale of 0 plane wish render onto translation plane place in world space want.

eg: render onto z = 4.0

matrix3d = 1, 0, 0, 0,               0, 1, 0, 0,            0, 0, 0, 4,            0, 0, 0, 1

i think that's right way around wpf you'd use system.windows.media.media3d.matrix3d functions make it.
