Member Function Documentation

◆ Alloc()

static BaseMaterial* Alloc ( Int32  type)
static

Allocates a base material. Destroy the allocated base material with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Parameters
[in]typeThe material type: Material Types
Returns
The allocated base material, or nullptr if the allocation failed.

◆ Free()

static void Free ( BaseMaterial *&  bl)
static

Destructs base materials allocated with Alloc(). Use AutoAlloc to automate the allocation and destruction based on scope.

Parameters
[in]blThe base material to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

◆ GetNext()

BaseMaterial* GetNext ( )

Gets the next material in the list. Convenience version of GeListNode::GetNext() returning a BaseMaterial*.

Returns
The next material, or nullptr if there is none. Cinema 4D owns the pointed base material.

◆ GetPred()

BaseMaterial* GetPred ( )

Gets the previous material in the list. Convenience version of GeListNode::GetPred() returning a BaseMaterial*.

Returns
The previous material, or nullptr if there is none. Cinema 4D owns the pointed base material.

◆ Update()

void Update ( Bool  preview,
Bool  rttm 
)

Recalculates the material's thumbnail and updates its internal values.

Note
Recalculating the thumbnail/RTTM image is time intensive. It only needs to be done to let the user change the view. The calculations are done asynchronously.
Parameters
[in]previewIf true the preview thumbnail will be updated.
[in]rttmIf true the real time texture map of the material will be recalculated.

◆ GetChannel()

BaseChannel* GetChannel ( Int32  id)

Retrieves the channel associated with a standard Material, such as the color channel or bump channel.

Warning
Only works with standard materials of type Mmaterial. For plugin materials this method does nothing and return nullptr.
Parameters
[in]idThe channel type: CHANNEL
Returns
The requested channel, or nullptr if there is no such channel or if the material is not a standard Material.

◆ InitTextures()

INITRENDERRESULT InitTextures ( const InitRenderStruct irs)

Initializes the material textures, loading any files required.

Parameters
[in]irsA struct with information about the upcoming material rendering. The caller owns the pointed struct.
Returns
The result of the initialization: INITRENDERRESULT

◆ UnlockTextures()

void UnlockTextures ( )

Unlocks all textures used by the material.

◆ Displace()

void Displace ( VolumeData sd,
const RayPolyWeight weights 
)

Calls the displacement routine of a material with associated barycentric weights.

Note
The passed VolumeData structure must be fully initialized and must contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.
[in]weightsUse nullptr. Private.

◆ ChangeNormal()

void ChangeNormal ( VolumeData sd)

Calls the bump routine of a material. For plugin materials this is MaterialData::ChangeNormal().
The call changes BaseVolumeData::bumpn.

Note
The passed VolumeData structure must be fully initialized and contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Warning
Normalization is not done by the routine.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.

◆ CalcSurface()

void CalcSurface ( VolumeData sd)

Computes the surface properties of the material. For plugin materials this is MaterialData::CalcSurface().
The call changes BaseVolumeData::col, BaseVolumeData::trans, BaseVolumeData::refl, BaseVolumeData::tray, BaseVolumeData::rray and/or BaseVolumeData::alpha (depending on the parameters).

Note
The passed VolumeData structure must be fully initialized and contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.

◆ CalcTransparency()

void CalcTransparency ( VolumeData sd)

Computes the transparency properties of the material. For plugin materials this is MaterialData::CalcTransparency().
The call changes BaseVolumeData::trans.

Note
The passed VolumeData structure must be fully initialized and contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.

◆ CalcAlpha()

void CalcAlpha ( VolumeData sd)

Computes the alpha properties of the material. For plugin materials this is MaterialData::CalcAlpha().
The call changes BaseVolumeData::alpha.

Note
The passed VolumeData structure must be fully initialized and contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.

◆ CalcVolumetric()

void CalcVolumetric ( VolumeData sd)

Computes the color of a volumetric ray in the material. For plugin materials this is MaterialData::CalcVolumetric().
The call changes VolumeData::col and/or VolumeData::trans.

Note
The passed VolumeData structure must be fully initialized and contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.

◆ InitCalculation()

void InitCalculation ( VolumeData sd,
INITCALCULATION  type 
)

If (and only if) (GetRenderInfo() & VOLUMEINFO::INITCALCULATION) is true, then call this function, with the right type, before any of the calculation functions is called.

Note
The passed VolumeData structure must be fully initialized and contain a render instance. This can only be achieved by copying/initializing from an existing VolumeData.
Parameters
[in]sdA volume data to use and modify. The caller owns the pointed VolumeData.
[in]typeSet the calculation type according to the method to call. See the default call order of MaterialData::InitCalculation().

◆ Compare()

Bool Compare ( BaseMaterial snd)

Check if the materials are identical.

Note
Only the name of the compared materials can be different.
Parameters
[in]sndThe material to compare with.
Returns
true if the materials contents are the same, otherwise false.

◆ GetPreview()

BaseBitmap* GetPreview ( Int32  flags)

Retrieves the preview picture of the material.

Parameters
[in]flags0 for the material editor preview, 1 for the viewport preview.
Returns
The preview picture. Guaranteed to be valid, i.e. not nullptr.
Note
To check if the preview has been calculated successfully, calling GetBw() on the returned bitmap should give a value superior than 0.

◆ GetRayIllumination()

RayIllumination* GetRayIllumination ( )

Private.

◆ GetAverageColor()

Vector GetAverageColor ( Int32  channel = -1)

Gets an average color for the material, based on the material preview.

Returns
The average color.

Returns
The return values are: VOLUMEINFO

◆ HasEditorTransparency()

Checks if the material supports viewport transparency.

Returns
true if the material support viewport transparency, otherwise false.

Bool InitEditorPreviewImage ( Int32  exponent,
BaseDocument doc,
BaseThread th,
Int32  doccolorspace,
Bool  linearworkflow
