setTexture() [1/4]

void setTexture

(

)

set texture (diffuse), which is responsible for the main appearance.

It is also means main texture, you can also call setTexture(texPath, NTextureData::Usage::Diffuse)

Parameters

texPath

texture path

setTexture() [2/4]

void setTexture

(

Texture2D *

tex

)

set texture (diffuse), which is responsible for the main appearance.

It is also means main texture, you can also call setTexture(texPath, NTextureData::Usage::Diffuse)

Parameters

tex	texture to be set

setTexture() [3/4]

void setTexture	(	Texture2D *	tex,
		NTextureData::Usage	usage,
		bool	cacheFileName = true )

Parameters

texPath	texture path
usage	Usage of this texture

getTexture() [1/2]

Texture2D * getTexture

(

)

const

Get texture (diffuse), which is responsible for the main appearance.

It is also means main texture, you can also call getTexture(NTextureData::Usage::Diffuse)

Returns

Texture used, return the texture of first mesh if multiple meshes exist

getTexture() [2/2]

Texture2D * getTexture

(

NTextureData::Usage

usage

)

Get texture.

Parameters

usage

Usage of returned texture

Returns

The texture of this usage, return the texture of first mesh if multiple meshes exist

calculateAABB()

void calculateAABB

(

)

calculate the AABB of the mesh

Note

the AABB is in the local space, not the world space

setDynamicInstancing()

void setDynamicInstancing

(

bool

dynamic

)

Set this to true and instancing objects within this mesh renderer will be recalculated each frame, use it when you plan to move objects, Otherwise, transforms will be built once for better performance.

to update transforms on demand use rebuildInstances()

addInstanceChild()

void addInstanceChild

(

Node *

child

)

Adds a child to use it's transformations for instancing.

The child is in the space of this Node, keep in mind that the node isn't added to the scene graph, it is instead retained and it's parent is set to this node, updates and actions will not run. the reason for this is performance.

Parameters

child,The

child to use for instancing.
