GDI+ in .NET

[Rohit Sharma]

Hi All,

Is the .NET GDI+ limited to drawing in 2D space ? I need to draw in 3D and
need to specify the points in terms of X,Y,Z....is this possible in GDI ?
Cheers

The GDI Graphics class is for drawing 2D only. You've got alot of work to
do for 3D. For one you need to implement your own Z buffering. You also
have to handle when a 2D object is rotated off the plane of the 2D surface.
Ie. If a circle is rotated off the page you'd end up drawing an Ellipse on
the GDI surface. When that circle intersects another circle in 3d is when
you'll need that z-buffering.

You'll basically have to draw pixel by pixel instead of by primitive.

This is really alot of work. Why don't you use Managed DirectX instead?
It also has better perfomance than GDI.

Thanks very much.

Can you direct me to a primer web site on the subject ? (with .NET)

Thanks

Open GL, nuff said.

DX is the crayola crayon and lego cube of 3d rendering APIs. oGL is mucho
nicer. Faster too.

There is a downloadable DirectX SDK that can be used for 3D
