Introduction

The Arc is one of the basic primitives that can be created on the fly. The Arc Tag encompasses the various attributes that are associated with a Arc, such as position, size and orientation. In addition, the Arc can be textured with a predefined image from a specific location.

Tag Attributes

• name
  • Usage: <sphere name="mysphere" />.
  • The name attribute is optional. If omited, the name is not used and thus cannot be retrieved within JavaScript.
  • The Arc is given an Identifier so that It can be retrieved and modified within JavaScript.
  • The name is a only accepts a string of Alpha-numeric characters.
• position
  • Usage: <arc position="0.3, 5.5, 3.8" />.
  • The position attribute is optional. If omited, the position defaults to the Origin location at {0.0, 0.0, 0.0}.
  • The position attribute holds a set of three floating point numbers separated by commas that are associated with the distance away from the Origin Point on the X, Y, and Z axis.
• orientation
  • Usage: <arc orientation="1.0, 1.0, 1.0" />.
  • The orientation attribute defines the direction in which the Arc is facing. The direction is defined by a vector value.
  • The orientation value only accepts three numbers that are separated by commas.
• size
  • Usage: <arc size="0.4" />.
  • The size attribute defines the size of the Sphere on the screen.
• texture
  • Usage: <arc texture="mytexture" />
  • The texture attribute contains the name identifier of a texture that is defined inside the canvas tag.
  • If the texture does not exist or is not defined, a default color of white is applied to the Arc.
  • The attribute must be Alpha-numeric and must point to a defined texture tag.

Syntax

<canvas>
  <arc name="myarc" position="0.0, 0.3, 0.5" orientation="0.2, 0.6, 1.3" size="1.9" texture="mytexture" />
</canvas>
