This is the next in a series of posts refuting some recurring claims about the death of SVG<\/abbr>, In the first post<\/a>, I gave a brief overview of SVG<\/abbr>. Each subsequent post takes a claim and refutes it.<\/p>\n

The Claim<\/h2>\n

SVG<\/abbr> is useless because it doesn’t support even basic 3D features<\/p><\/blockquote>\n

This claim makes a little more sense than the previous one, but not much. The focus of SVG<\/abbr> was on 2 dimensional vector graphics<\/em>. It is obviously possible to render 3D objects by projecting them onto a 2D representation. After all, that’s how 3D graphics are always displayed on a monitor. You can use SVG<\/abbr> as the 2D representation. However, SVG<\/abbr> does not provide any particular help for projections or 3D objects, because its focus is 2D graphics.<\/p>\n

All of the image manipulation supported by SVG<\/abbr> is designed to support 2D vector graphics. This means that there is no support for perspectives or non-linear transforms. The painting model does not support explicit z-ordering. There is no support for 3D coordinates. None of these things are required for 2D vector graphics, so they do not exist in SVG<\/abbr>.<\/p>\n

There are some separate projects that target 3D vector formats (VRML<\/abbr> and X3D are probably the most complete). X3D has even been written with a goal of being compatible with SVG<\/abbr>.<\/p>\n

The fact that SVG<\/abbr> doesn’t support 3D does not reduce its utility as a 2D vector image format. Despite this claim, SVG<\/abbr> is still alive and well.<\/p>\n
