Hi,

This is a view moving vanishing point over and over.

Hi,

This image is a bird view.
Vanishing point moved higher and higher.

Hi,

I've added pyramid corn roof.
This is a single shape.
If you turn the roof moving vanishing point,
each 4 face of the roof become visible or in visible.
As this shape is a single shape, you cannot fill with multi color.
Attached Visio drawing was saved by the Visio 2010 Beta.
Can you open it with Visio 2007?

Hi,

Pyramid corn roof is enhanced to multi colors. :) :)
This shape is a group.
To change the color of each face, you need to select sub shape in the group.
With color map you can define the color of the face even if it is behind other faces and not visible.
You can define the color of faces not only on the color map but also on the face directly.
The clone technology(:D) is used. Did you remember that shapesheet function "SetAtRef"?
You can hide the color map with right click menu on the shape.

Hi,

Added a 3-D block.
Now, you can construct perspective view more fast. :)

Junichi San, 5 thumbs up.
That's the only pseudo 3D work that I saw, really worth to do it in Visio.
By the way I'm travelling to Tokyo in 2 weeks. May be I'll meet you in the metro there? ;)

Hi,

I am now trying to make perspective views of circles.
Image57.jpg and Image58.jpg.
All frames are hidden in image58.

And Visio example drawing.
This drawing uses VBA macro to fit ellipses to the frames.
This drawing has problems.
In Visio 2010 beta, some times window zoom suddenly changes while vanishing point is moving.
The problem happens when the page is set to "Let Visio expand the page".
It may be a matter of zero divide or overflow when calculating the parameters of ellipes.
If the page is set to "Predefined Size", you have no problem.
Now, the page 1 of this drawaing is set to "Predefined Size".
In Visio 2007 there is no problem.

Hi,

I am now trying to make an ellipse in a quadrangle, ABCD
as is shown in image59.jpg.
It may be a part of perspective view.
I think the center of the ellipse is the center of gravity of quadrangle ABCD.
In numerical calculation in Visio, the center of ellipse is
close to the center of gravity in about 0.01 mm.
But I cannot find how it is proved geometrically.
If it is proved and if it is right, the calculation of the parameters may be simplified.
I think calculation may be done in shapesheet.
Calculation may be faster and more simple than that done with VBA.
Any idea?

talk about serendipity.....was reviewing geometry with my daughter

Check out centroids, median, altitude of a triangle.   In essence, it defines how you can find the criss cross (AD and BC if I recall from your
diagram) lengths which determines O.  The math is pretty simple so could do in a spread sheet.
