Function Documentation

applyColor

Apply a color to every vertex in a mesh. A MOAIRegion and/or a blending mode may optionally be provided. Blending mode is one of COLOR_ADD, COLOR_MULTIPLY, COLOR_OVERWRITE, COLOR_SUBTRACT.

---

function applyColor ( MOAIVertexFormat format, MOAIStream vtxStream, ZLColorVec color [, number length, number blendMode ] )

Parameters

MOAIVertexFormat	format
MOAIStream	vtxStream
ZLColorVec	color
number	length Optional.
number	blendMode Optional.

Returns

nil

Note

---

function applyColor ( MOAIVertexFormat format, MOAIStream vtxStream, ZLColorVec color, MOAIRegion region [, number length, number pad, number blendMode ] )

Parameters

MOAIVertexFormat	format
MOAIStream	vtxStream
ZLColorVec	color
MOAIRegion	region
number	length Optional.
number	pad Optional.
number	blendMode Optional.

Returns

nil

Note

applyLightFromImage

Apply vertex colors from an image as a sperical map indexed by vertex normals. Middle of image is the equator, with the poles at image top and bottom. (Resolution diminishes as sample approaches poles.) An optional linear alpha gradient may be also be applied. Blending mode is one of COLOR_ADD, COLOR_MULTIPLY, COLOR_OVERWRITE, COLOR_SUBTRACT.

---

function applyLightFromImage ( MOAIVertexFormat format, MOAIStream vtxStream, MOAIImage image [, number length, number blendMode, number a0, number a1, number x0, number y0, number z0, number x1, number y1, number z1 ] )

Parameters

MOAIVertexFormat	format
MOAIStream	vtxStream
MOAIImage	image
number	length Optional.
number	blendMode Optional.
number	a0 Optional.
number	a1 Optional.
number	x0 Optional.
number	y0 Optional.
number	z0 Optional.
number	x1 Optional.
number	y1 Optional.
number	z1 Optional.

Returns

nil

applyLinearGradient

Apply a linear color gradient. Blending mode is one of COLOR_ADD, COLOR_MULTIPLY, COLOR_OVERWRITE, COLOR_SUBTRACT.

---

function applyLinearGradient ( MOAIVertexFormat format, MOAIStream vtxStream [, number length, number x0, number y0, number z0, number x1, number y1, number z1, number r0, number g0, number b0, number a0, number r1, number g1, number b1, number a1, boolean cap0, boolean cap1, number blendMode ] )

Parameters

number	x0 Optional.
number	y0 Optional.
number	z0 Optional.
number	x1 Optional.
number	y1 Optional.
number	z1 Optional.
number	r0 Optional.
number	g0 Optional.
number	b0 Optional.
number	a0 Optional.

number	g1 Optional.
number	b1 Optional.
number	a1 Optional.
boolean	cap0 Optional.
boolean	cap1 Optional.
number	blendMode Optional.

Returns

nil

getMesh

Return the vertices as an MOAIVertexBuffer and MOAIIndexBuffer, or as a ready-to-render MOAIMesh.

---

function getMesh ( MOAIVertexFormat format, MOAIStream vtxStream, number vtxStreamLength, MOAIStream idxStream, number idxStreamLength, MOAIVertexBuffer vtxBuffer, MOAIIndexBuffer idxBuffer [, number idxSizeInBytes ] )

Parameters

MOAIVertexFormat	format
MOAIStream	vtxStream
number	vtxStreamLength
MOAIStream	idxStream
number	idxStreamLength
MOAIVertexBuffer	vtxBuffer
MOAIIndexBuffer	idxBuffer
number	idxSizeInBytes Optional.

Returns

number totalElements

Note

---

function getMesh ( MOAIVertexFormat format, MOAIStream vtxStream, number vtxStreamLength, MOAIStream idxStream, number idxStreamLength [, number idxSizeInBytes ] )
