SCNTextureInfo Class Reference

Inherits from	NSObject
Declared in	SCNTextureInfo.h SCNTextureInfo.m

Overview

An object which scans the assimp material, identifies if a color, embedded texture or external texture exists and generates a color/texture object.

The color and texture objects are platform independent CoreGraphics objects thereby removing the depdence on external paths for texture resources.

Other Methods

`textureType`

The texture type: diffuse, specular etc.

@property enum aiTextureType textureType

Discussion

The texture type: diffuse, specular etc.

Declared In

SCNTextureInfo.h

`– initWithMeshIndex:textureType:inScene:atPath:`

Create a texture metadata object for a material property.

- (id)initWithMeshIndex:(int)aiMeshIndex textureType:(enum aiTextureType)aiTextureType inScene:(const struct aiScene *)aiScene atPath:(NSString *)path

Parameters

`aiMeshIndex`	The index of the mesh to which this texture is applied.
`aiTextureType`	The texture type: diffuse, specular etc.
`aiScene`	The assimp scene.
`path`	The path to the scene file to load.

Return Value

A new texture info.

Discussion

Create a texture metadata object for a material property.

Declared In

SCNTextureInfo.h

`– getMaterialPropertyContents`

The contents of the material property which can be a texture or color.

- (id)getMaterialPropertyContents

Return Value

The contents which is either a texture or a color.

Discussion

The contents of the material property which can be a texture or color.

Declared In

`– releaseContents`

Releases the core graphics image resources used to load colors and textures.

- (void)releaseContents

Discussion

Other Methods

`– checkTextureTypeForMaterial:withTextureType:inScene:atPath:`

Inspects the material texture properties to determine if color, embedded texture or external texture should be applied to the material property.

- (void)checkTextureTypeForMaterial:(const struct aiMaterial *)aiMaterial withTextureType:(enum aiTextureType)aiTextureType inScene:(const struct aiScene *)aiScene atPath:(NSString *)path

Parameters

`aiMaterial`	The assimp material.
`aiTextureType`	The material property: diffuse, specular etc.
`aiScene`	The assimp scene.
`path`	The path to the scene file to load.

Discussion

Inspects the material texture properties to determine if color, embedded texture or external texture should be applied to the material property.

Declared In

`– generateCGImageForEmbeddedTextureAtIndex:inScene:`

Generates a bitmap image representing the embedded texture.

- (void)generateCGImageForEmbeddedTextureAtIndex:(int)index inScene:(const struct aiScene *)aiScene

Parameters

`index`	The index of the texture in assimp scene’s textures.
`aiScene`	The assimp scene.

Discussion

Generates a bitmap image representing the embedded texture.

Declared In

SCNTextureInfo.m

`– generateCGImageForExternalTextureAtPath:`

Generates a bitmap image representing the external texture.

- (void)generateCGImageForExternalTextureAtPath:(NSString *)path

Parameters

`path`	The path to the scene file to load.

Discussion

Generates a bitmap image representing the external texture.
