Detailed Description

Data structure for a material.

Material data is stored using a key-value structure. A single key-value pair is called a 'material property'. C++ users should use the provided member functions of aiMaterial to process material properties, C users have to stick with the aiMaterialGetXXX family of unbound functions. The library defines a set of standard keys (AI_MATKEY_XXX).

void aiMaterial::Clear

(

)

Removes all properties from the material.

The data array remains allocated so adding new properties is quite fast.

static void aiMaterial::CopyPropertyList	(	aiMaterial *	pcDest,
		const aiMaterial *	pcSrc
	)

static

Copy the property list of a material.

Parameters

pcDest	Destination material
pcSrc	Source material

template<typename Type >

aiReturn aiMaterial::Get	(	const char *	pKey,
		unsigned int	type,
		unsigned int	idx,
		Type *	pOut,
		unsigned int *	pMax
	)		const

Retrieve an array of Type values with a specific key from the material.

Parameters

pKey	Key to search for. One of the AI_MATKEY_XXX constants.
type	.. set by AI_MATKEY_XXX
idx	.. set by AI_MATKEY_XXX
pOut	Pointer to a buffer to receive the result.
pMax	Specifies the size of the given buffer, in Type's. Receives the number of values (not bytes!) read. NULL is a valid value for this parameter.

		unsigned int	type,
		unsigned int	idx,

idx	Index of the texture to be retrieved.
pOut	Reference to receive the output value

		aiTextureOp *	op = `NULL`,
		aiTextureMapMode *	mapmode = `NULL`
	)		const

Helper function to get all parameters pertaining to a particular texture slot from a material.

This function is provided just for convenience, you could also read the single material properties manually.

Parameters

type	Specifies the type of the texture to be retrieved ( e.g. diffuse, specular, height map ...)
index	Index of the texture to be retrieved. The function fails if there is no texture of that type with this index. GetTextureCount() can be used to determine the number of textures per texture type.
path	Receives the path to the texture. NULL is a valid value.
mapping	The texture mapping. NULL is allowed as value.
uvindex	Receives the UV index of the texture. NULL is a valid value.
blend	Receives the blend factor for the texture NULL is a valid value.
op	Receives the texture operation to be performed between this texture and the previous texture. NULL is allowed as value.
mapmode	Receives the mapping modes to be used for the texture. The parameter may be NULL but if it is a valid pointer it MUST point to an array of 3 aiTextureMapMode's (one for each axis: UVW order (=XYZ)).

unsigned int aiMaterial::GetTextureCount

(

aiTextureType

type

)

const

Get the number of textures for a particular texture type.

Parameters

type	Texture type to check for

Returns: Number of textures for this type.

Note: A texture can be easily queried using GetTexture()

aiReturn aiMaterial::RemoveProperty	(	const char *	pKey,
		unsigned int	type = `0`,
		unsigned int	index = `0`
	)

Remove a given key from the list.

The function fails if the key isn't found

Parameters

pKey	Key to be deleted
type	Set by the AI_MATKEY_XXX macro
index	Set by the AI_MATKEY_XXX macro
