Detailed Description

class IMaterialControllerProperty : public RED::IREDObject

Material controller property interface.

@related The Material Controller, Writing Material Controller Properties, class RED::IMaterialController

See the RED::IMaterialController interface documentation and the \ref bk_bm_the_material_controller document for an in-depth understanding of the REDsdk material controller feature.

RED::IMaterialControllerProperty are basic components of a material controller. Each property describe the behavior of an underlying material at a macroscopic level.

Let’s take the example of a shiny plastic material. Intuitively, such a material should expose at least two parameters: one for the plastic color and another one for the shininess intensity. In REDsdk, a plastic material would use a RED::RenderShaderPhong for the lighting shading. This kind of shader exposes a lot more parameters than just two colors and therefore is a lot more complex to set for a non-professional user. A programmer using REDsdk can create a RED::IMaterialController for his shiny plastic material with the two mentioned colors added as properties. He would have to write a little bit of MSC code (Material Controller Script introduced in the Programming guide document) to connect properties input to underlying shader ones.

Material controller properties can be of any following built-in types:

float, integer, boolean, color, texture 2D, 3D or cube, layerset.

For each of these types, two accessors are available (one for reading, another one for writing).

When accessing to a property using an accessor of the wrong type, an undetermined result will be returned. Using an accessor in write mode overwrite the type of the property with the one of the accessor used.

A range of definition can be defined for float and integer scalar properties. REDsdk will not check that assigned values fall inside the range (if defined). It’s up to the caller to check them before setting them.

Finally, instances of that class can have additional information about the role they play in the underlying material setup (RED::IMaterialControllerProperty::GetDescription).

virtual RED_RC SetScript(const RED::String &iScript) = 0

Sets the script associated with the property.

The script is automatically compiled when set.

Parameters

iScript – Source code of the script.

virtual RED_RC Set(const RED::IMaterialControllerProperty &iProperty, const RED::State &iState) = 0

Sets the property from an input RED::IMaterialControllerProperty instance.

This method overrides only the property value and type with the input ones. Property name, script and description are left unmodified.

Parameters

• iProperty – reference to the input property to be copied.

• iState – Current transaction.

Returns

RED_OK on success,

RED_FAIL otherwise.

virtual RED_RC SetColor(const RED::Color &iColor, const RED::State &iState) = 0

If the property type is not PYT_COLOR, the returned color may be undefined.

Returns

the property color.

virtual RED_RC SetFloatValue(float iValue, const RED::State &iState) = 0

Sets the float property value.

This method automatically set the property type to PYT_FLOAT. If the type cnanges, the value range is reset to [-FLT_MAX, FLT_MAX].

Parameters

• iValue – Poperty value.

• iState – Current transaction.

Returns

RED_OK on success,

RED_FAIL otherwise.

virtual float GetFloatValue() const = 0

If the property type is not PYT_FLOAT, the returned value may be undefined.

Returns

the property value.

virtual RED_RC SetIntegerValue(int iValue, const RED::State &iState) = 0

Sets the integer property value.

This method automatically set the property type to PYT_INTEGER. If the type changes, the value range is reset to [INT_MIN, INT_MAX].

Parameters

• iValue – Poperty value.

• iState – Current transaction.

Returns

RED_OK on success,

RED_FAIL otherwise.

virtual int GetIntegerValue() const = 0

Gets the integer property value.

If the property type is not PYT_INTEGER, the returned value may be undefined.

Returns

the property value.

virtual RED_RC SetBooleanValue(bool iValue, const RED::State &iState) = 0

Sets the boolean property value.

This method automatically set the property type to PYT_BOOL.

Parameters

• iValue – Poperty value.

• iState – Current transaction.

Returns

RED_OK on success,

RED_FAIL otherwise.

virtual bool GetBooleanValue() const = 0

Gets the boolean property value.

If the property type is not PYT_BOOLEAN, the returned value may be undefined.

Returns

the property value.

virtual RED_RC SetVector4(const RED::Vector4 &iVector, const RED::State &iState) = 0

Sets the property vector4.

This method automatically set the property type to PYT_VECTOR4.

Parameters

• iVector – Poperty vector4.

• iState – Current transaction.

Returns

virtual void SetRange(float iStart, float iEnd) = 0

Sets the definition range of the property.

If the property type is not PYT_FLOAT, the call will have no effect. The range includes iStart and iEnd values.

Parameters

• iStart – Starting value of the range.

virtual RED_RC SetTexture(const RED::Object *iTexture, const RED::String &iPath, const RED::State &iState) = 0

Sets the property texture.

PYT_TEXTURECUBE or PYT_TEXTURECOMPOSITE according to the interface supported by iTexture.

If a previous texture was set, it is replaced by the new one (even if the new is NULL) but not deleted. If the new texture is NULL, the property type will be set to PYT_TEXTURE2D.
