Abstract
This working draft defines features of the Scalable Vector Graphics (SVG) Language that are specifically for display environments.
This document defines the markup used by SVG Transforms. SVG Transforms allows two-dimensional objects to be transformed using three-dimensional transformations.
Although originally designed for use in SVG, some aspects of this specification are defined in XML and are accessed via presentation properties, and therefore could be used in other environments, such as HTML styled with CSS and XSL:FO.
This document defines the markup used by SVG Transforms.
Status of This Document
This will be the last published Working Draft of this specification. Work will continue with a combined CSS and SVG Transforms specification operating under the FX Taskforce. The latest Editors' Draft of the new specification is available.
This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
Publication as a Working Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This document is the first public working draft of this specification. There will be an accompanying Transforms Primer that lists the ways SVG Transforms may be used.
This document has been produced by the W3C SVG Working Group as part of the W3C Graphics Activity within the Interaction Domain.
We explicitly invite comments on this specification. Please send them to www-svg@w3.org (archives), the public email list for issues related to vector graphics on the Web. Acceptance of the archiving policy is requested automatically upon first post to either list. To subscribe to this list, please send an email to www-svg-request@w3.org with the word subscribe in the subject line.
The latest information regarding patent disclosures related to this document is available on the Web. As of this publication, the SVG Working Group are not aware of any royalty-bearing patents they believe to be essential to SVG.
This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.
How to read this document and give feedback
This working draft of SVG Transforms introduces new Transforms syntax and markup for the SVG language. One of the goals is that this specification can be re-used more easily by other specifications that want to have advanced Transforms features. This specification introduces syntax that may not be backwards compatible with older SVG User Agents, and the use of this syntax should be accompanied by a fallback using the 'switch' element.
The main purpose of this document is to encourage public feedback. The best way to give feedback is by sending an email to www-svg@w3.org. Please include some kind of keyword that identifies the area of the specification the comment is referring to in the subject line of your message (e.g 'Section X.Y - Foo attribute values' or 'Transforms Functionality'). If you have comments on multiple areas of this document, then it is probably best to split those comments into multiple messages.
The public are welcome to comment on any aspect in this document, but there are a few areas in which the SVG Working Group are explicitly requesting feedback. These areas are noted in place within this documentlike this. There is also a specific area related to the specification that is listed here:

1. Introduction
This document is normative and lists features that may be used in the context of display. The various scenarios are listed in the SVG Transforms Requirements document.
Note that even though this specification references parts of SVG Tiny 1.2 it does not require a complete or SVG Tiny 1.2 implementation.
This document contains explicit conformance criteria that overlap with some RNG definitions in requirements. If there is any conflict between the two, the explicit conformance criteria are the definitive reference.
The SVG Transforms module extends the two-dimensional transformation pipeline in SVG to allow graphical elements to be transformed in three-dimensions. For elements to be transformed using three-dimensonal transformations a Z axis is introduced by this module. The elements in SVG can be positioned along the Z axis and transformed in 3D space, however the elements themselves still remain two-dimensional. A perspective projection can be applied to elements to give the illusion of depth. The projection plane for a perspective projection is the X-Y plane (where Z = 0). All are still rendered to this plane. Unless stated otherwise, all elements are rendered in document order as per the existing SVG specifications.
1.1. Projection Matrix
The projection matrix provides a means for depth information of an element to be specified. Depth information can be represented as a 4x4 matrix of the following form:
The projection transformation matrix is also expressed as a vector [x y d]. The 'perspective' property is used to set the perspective projection matrix of an object.
1.2. 3D Transformation Matrix
The 3D transformation matrices provide a means to transform a point in 3D space before it is projected to a 2D plane. Mathematically, all 3D transforms can be represted as a 4x4 transformation matrices.
The 3D transforms matrices are of the following form:
The 3D transformation matrix is also expressed as a vector [a b c d e f g h i j k m]. The transforms in the TransformsList Extensions can be used to set the transformation of an object.
The CSS 3D Transforms specification uses 16 values.
1.2.1. 3D Translation Matrix
A 3D Translation is equivalent to the matrix:
1.2.2. 3D Scaling Matrix
A 3D Scaling is equivalent to the matrix:
1.2.3. 3D Rotation
A 3D Rotation is equivalent to the matrix:
where:
1.2.4. 3D Rotation about X
A 3D Rotation about the X axis is equivalent to the matrix:
1.2.5. 3D Rotation about Y
A 3D Rotation about the Y axis is equivalent to the matrix:
1.2.6. 3D Rotation about Z
A 3D Rotation about the Z axis is equivalent to the matrix:
2. Perspective Definitions
The SVG Working Group is currently discussing how to give the author the ability to change the Z order of objects. One possible solution is to use the CSS 'transform-style' property on a group. When set to 'preserve-3d', it allows child elements in the group to be re-ordered based on their Z position (rather than document order). A similar option is to introduce a container element 'layeredG' or 'g3d' where the order of rendering the child elements is based on its Z position. Note that in either case I different tree traversal order may only be needed. This would help restrict the complexity when rendering 3D Transforms in SVG. The SVG Working Group believes this is the most optimal solution without causing too many complexities to SVG Implementations. The SVG Working Group welcomes any comments or suggestions regarding this feature.
2.1. The 'transform-origin' property
The 'transform-origin' property establishes the transformation origin of an element in the element's CTM .
| Value: | | none |
| Initial: | 0 0 0 |
| Applies to: | Renderable elements. For SVG container elements and graphics elements. |
| Inherited: | no |
| Percentages: | no |
| Media: | visual |
| Animatable: | yes |

specifies the x of the new origin of the element using one of the values: left | center | right | . This coordinate is established using the bounding box of the element to which the transform is applied (see Object bounding box units).
The value left means the left most edge of the object's bounding box.
The value center means the horizontal center of the object's bounding box.
The value right means the right most edge of the object's bounding box.
specifies the y of the new origin of the element using one of the values: top | center | bottom | . This coordinate is established using the bounding box of the element to which the transform is applied (see Object bounding box units).
The value top means the top most edge of the object's bounding box.
The value center means the vertical center of the object's bounding box.
The value bottom means the right most edge of the object's bounding box.
- specifies the z of the new origin of the element. The value is in the current user coordinate system.
The 'transform-origin' is the equivalent of the following specification: translate(, , ) translate(-, -, -) . If a already specifies a transformation origin the 'transform-origin' is still applied as per the equivalent specification specified above.
This property is similar to property in the CSS 3D Transforms specification.
2.2. The 'perspective' Property
Focus Matrix 1 0 1 Beta
The 'perspective' property specifies a projeciton matrix to apply to child elements contained within the current element. It effectively sets the viewpoint to project an element on the X-Y viewing plane (where z=0).
| Value: | | none |
| Initial: | none |
| Applies to: | Renderable elements. For SVG container elements and graphics elements. |
| Inherited: | no |

The coordinate definitions are as follows:specifies the x of the perspective viewpoint on the X-Y viewing plane. The value is in the current user coordinate system.
specifies the y of the perspective viewpoint on the X-Y viewing plane. The value is in the current user coordinate system.
specifies the representing the viewpoint distance from the X, Y viewing plane. The value is in the current user coordinate system.

5. Converting a 4x4 to a 3x3 matrix
A rectangle ABCD is given on plane X-Y. When a 3D affine transform and perspective projection are applied, a quadrangle A'B'C'D' will appear on the X-Y plane. Note the X-Y plane is the projection plane. Generally, this mapping is expressed as a 4x4 matrix.
An affine 3D Transform MatrixT is given as
A Perspective Projection MatrixP is given as
The combined matrix Mcan be expressed as
An arbitary point K can be expressed as (kx, ky, 0). If the point K is transformed to point K'(k'x,k'y,0), the eqation is derived
A non-affine 3x3 matrix (F) can be expressed as a 4x4 where the components that make up the Z axis are set to 0 as shown below
If matrix F can be used to map point K to point K' as shown below
Expression 2 can be shown to be related to Expression 3 for any arbitary point kx, ky by a constant m
Thus it can be said from the above relationship
Therefore, the combination of An affine 3D Transform Matrix and a Perspective Projection Matrix can be expressed by using a 3x3 matirx as follows
6. RelaxNG Schema for SVG Transforms 1.0
The schema for SVG Transforms 1.0 is written in RelaxNG [RelaxNG], a namespace-aware schema language that uses the datatypes from XML Schema Part 2 [Schema2]. This allows namespaces and modularity to be much more naturally expressed than using DTD syntax. The RelaxNG schema for SVG Transforms 1.0 may be imported by other RelaxNG schemas, or combined with other schemas in other languages into a multi-namespace, multi-grammar schema using Namespace-based Validation Dispatching Language [NVDL].
Unlike a DTD, the schema used for validation is not hardcoded into the document instance. There is no equivalent to the DOCTYPE declaration. Simply point your editor or other validation tool to the IRI of the schema (or your local cached copy, as you prefer).
The RNG is under construction, and only the individual RNG snippets are available at this time. They have not yet been integrated into a functional schema. The individual RNG files will be available soon.

When you are new to prepping, everything becomes a little too overwhelming. I wish I could tell you the 'lost' feeling changes over time, but it doesn't. The truth is; while you expand your 'prepper' knowledge, your interests in new subjects can spiral out of control. And, when you think you have figured something out, you may realize that you have solved only a small piece of the puzzle. Therefore, after much debate, sketching on the chalkboard, and revision after revision, we are pleased to offer our initial Prepper Matrix.

The Prepping Matrix helps you visualize everything that needs to be accomplished. As adults, we tend to focus on areas that we are interested in, and neglect areas that we are not. When I first started prepping, I looked for a prepping road map, but was unable to find one. So after we launched Prepper Link, we started working on what we call the Prepping Matrix. In addition to your personal preps, this matrix can be used to explain what is involved in the prepping lifestyle to those just getting started. Additionally, a group can use it to identify priorities and responsibilities.
Prepper Link is a publisher of original content geared towards self-sufficiency, prepping and survivalism. Our website features original articles from a variety of contributors, a comprehensive forum, and a social network component that provides preppers with a means to find other preppers and create groups.
