Detailed Description

2D symmetric triangle filter (aka linear / tent filter)

Creates a single triangle.

Note:

triangle corresponds to the underlying Milton class 'TriangleFilter.'

If you do not specify vertices for the triangle, it will lie in the y=0 plane, with normal [ 0, 1, 0 ].

triangle corresponds to the underlying Milton class 'Triangle.'

Example usage:

"triangle" : {

"vertices" : [

4, -2.70651, 0.256,

4, -2.08375, -0.526323,

-4, -2.08375, -0.526323 ],

},

Attribute Documentation

ureal_t triangle::support

Size of symmetric filter in pixels.

type	positive real scalar
optional	true
default	2
units	pixels

vector9 triangle::vertices

Triangle vertices.

Expects 9 scalar values: [ vAx, vAy, vAz, vBx, vBy, vBz, vCx, vCy, vCz ], where A, B, and C denote the first, second and third vertices respectively and vAx, vAy, vAz denotes their respective x, y, and z components.

type	vector9
optional	true
default	[ 0, 0, 0, 0, 0, 0.5, 0.5, 0, 0 ]

vector9 triangle::normals

Per-vertex triangle normals.

Expects 9 scalar values: [ nAx, nAy, nAz, nBx, nBy, nBz, nCx, nCy, nCz ], where A, B, and C denote the first, second and third vertices respectively and nAx, nAy, nAz denotes their respective x, y, and z components.

Note:

If no normals are specified, the geometric normal will be used as the counter-clockwise cross-product of the triangle vertices.

type	vector9
optional	true

vector6 triangle::uvs

Per-vertex UV texture coordinates.

Expects 6 scalar values: [ Au, Av, Bu, Bv, Cu, Cv ], where A, B, and C denote the first, second and third vertices respectively and Au, Av denotes their respective u, v texture coordinates.

Note:

If no uvs are specified, sensible defaults will be used.

type	vector6
optional	true
