Tipsify

Methods

<static> calculateACMR

Calculates the average cache miss ratio (ACMR) for a given set of indices.

Parameters:

Name	Type	Argument	Default	Description
description.indices	Array			Lists triads of numbers corresponding to the indices of the vertices in the vertex buffer that define the geometry's triangles.
description.maximumIndex	Number	<optional>		The maximum value of the elements in args.indices. If not supplied, this value will be computed.
description.cacheSize	Number	<optional>	24	The number of vertices that can be stored in the cache at any one time.

Throws:

• DeveloperError : indices is required.
• DeveloperError : indices length must be a multiple of three.
• DeveloperError : cacheSize must be greater than two.

Returns:

Number The average cache miss ratio (ACMR).

Example

var indices = [0, 1, 2, 3, 4, 5];
var maxIndex = 5;
var cacheSize = 3;
var acmr = Tipsify.calculateACMR({indices : indices, maxIndex : maxIndex, cacheSize : cacheSize});

<static> tipsify

Optimizes triangles for the post-vertex shader cache.

Parameters:

Name	Type	Argument	Default	Description
description.indices	Array			Lists triads of numbers corresponding to the indices of the vertices in the vertex buffer that define the geometry's triangles.
description.maximumIndex	Number	<optional>		The maximum value of the elements in args.indices. If not supplied, this value will be computed.
description.cacheSize	Number	<optional>	24	The number of vertices that can be stored in the cache at any one time.

Throws:

• DeveloperError : indices is required.
• DeveloperError : indices length must be a multiple of three.
• DeveloperError : cacheSize must be greater than two.

Returns:

Array A list of the input indices in an optimized order.

Example

var indices = [0, 1, 2, 3, 4, 5];
var maxIndex = 5;
var cacheSize = 3;
var reorderedIndices = Tipsify.tipsify({indices : indices, maxIndex : maxIndex, cacheSize : cacheSize});
